What do Salmonella, E coli, and bread have in common?

Say you happen to eat some chicken fingers contaminated with bacteria because the 19-year old kid behind the counter failed to wash his hands after using the toilet, or because the kitchen is poorly managed with unwashed counters and cutting boards, or because the food is undercooked. You get a bout of diarrhea and cramps, along with a desire to banish chicken from your life.

Here's yet another odd wheat phenomenon: About 30% of people who eliminate wheat from their lives experience an acute food poisoning-like effect on re-exposure. You've been wheat-free for, say, 6 months. You've lost 25 lbs from your wheat belly, you've regained energy, joints feel better. You go to an office party where they're serving some really yummy looking bruschetta. Surely a couple won't hurt! Within a hour, you're getting that awful rumbling and unease that precede the explosion.

The majority of people who experience a wheat re-exposure syndrome will have diarrhea and cramps that can last from hours to days, similar to food poisoning. (Why? Why would a common food trigger a food poisoning-like effect? It happens too fast to attribute to inflammation.) Others experience asthma attacks, joint pains that last 48 hours to a week, mental fogginess, emotional distress, even rage (in males).

Wheat re-exposure in the susceptible provides a tidy demonstration of the effects of this peculiar product of genetic research. So if you are wheat-free but entertain an occasional indulgence, don't be surprised if you have to make a beeline to the toilet.

The world of intermediate carbohydrates

There are clear-cut bad carbohydrates: wheat, oats, cornstarch, and sucrose. (Fructose, too, but in a class of bad all its own.)

Wheat: The worst. Not only does wheat flour increase blood sugar higher than nearly all other carbohydrates, it invites celiac disease, neurologic impairment, mental and emotional effects, addictive (i.e., exorphin) effects, asthma, irritable bowel syndrome, acid reflux, sleepiness, sleep disruption, arthritis . . . just to name a few.

Oats: Yeah, yeah, I know: "Lowers cholesterol." But nobody told you that oats, including slow-cooked oatmeal, causes blood sugar to skyrocket.

Cornstarch: Like wheat, cornstarch flagrantly increases blood sugar.It also stimulates appetite. That's why food manufacturers put it in everything from soups to frozen dinners.

Sucrose: Not only does sucrose create a desire for more food, it is also 50% fructose, the peculiar sugar that makes us fat, increases small LDL particles, increases triglycerides, slows the metabolism of other foods, encourages diabetes, and causes more glycation than any other sugar.

But there are a large world of "other" natural carbohydrates that don't fall into the really bad category. This includes starchy beans like black, kidney, and pinto; rices such as white, brown, and wild; potatoes, including white, red, sweet, and yams; and fruits. It includes "alternative" grains like quinoa, spelt, triticale, amaranth, and barley.

For lack of a better term, I call these "intermediate" carbohydrates. They are not as bad as wheat, etc., but nor are they good. They will still increase blood glucose, small LDL, triglycerides, etc., just not as much as the worst carbohydrates.

The difference is relative. Say we compare the one-hour blood glucose effects of 1 cup of wheat flour product vs. one cup of quinoa. Typical blood sugar after wheat product: 180 mg/dl. Typical blood sugar after quinoa: 160 mg/dl--better but still pretty bad.

Some people are so carb-sensitive that they should avoid even these so-called intermediate carbohydrates. Others can have small indulgences, e.g., 1/2 cup, and not generate high blood sugars.

Heroin, Oxycontin, and a whole wheat bagel

For a substantial proportion of people who remove wheat from their diet, there is a distinct and unpleasant withdrawal syndrome. Here are the comments of Heart Scan Blog reader, Scott, from Texas:

Hello Dr. Davis,

I've been experimenting with diet, converging upon a Paleo type diet, but I keep running into problems. I have isolated the problem to cutting out wheat.

Sugar, rice, fruit, corn, potatoes, etc. are relatively ok to add or remove from the diet, but cutting out wheat in particular brings on a moderate headache with heavy fatigue all day long. This resembles the wheat withdrawal symptoms I found on your blog. As I write this, I'm on day 8 of wheat-free. I consume a fair variety of meat and veggies each day with a moderate amount of white rice for carbs. Perhaps a bowl of corn flakes with milk and half a bar of dark chocolate a day. I've learned from experience over the past 5 months or so that none of these foods affect the withdrawal. It's purely wheat.

My question is, what is the range of times for withdrawal symptoms that you've heard from different people? Has there been anyone who never recovered from the wheat withdrawal symptoms even after many months?

It's very tough to get work done like this, and even though my body and head feel much healthier in general, my sinuses have cleared, don't have to take a big nap after I eat, etc., I don't want to go down a path where this is the way things are going to be forever. 



People who have never experienced wheat withdrawal pooh-pooh the effect. But, for about 30% of people, wheat withdrawal is a real, palpable, and sometimes incapacitating experience.

Beyond removing an exceptionally digestible carbohydrate that yields blood sugar rises higher than nearly any other known food (due to the unique amylopectin structure of wheat-derived carbohydrate), wheat withdrawal is a form of opiate withdrawal, somewhat like stopping heroin, Oxycontin, and other opiates. Stop eating whole wheat toast for breakfast, whole grain sandwiches for lunch, or whole grain pasta for dinner, and the flow of exorphins, i.e., exogenous morphine-like compounds, stops. You experience dysphoria (sadness, unhappiness), mental "fog," inability to concentrate, fatigue, and decreased capacity to exercise. It is milder than withdrawal from prescription opiates. Unlike withdrawal from more powerful opiates like heroine, there are, thankfully, no seizures or hallucinations. There are also no deaths.

In my experience, most people get through with wheat withdrawal in about 5 days. An occasional person will struggle for as long as 4 weeks. Thankfully for Scott, I've never seen it last longer than 4 weeks. (Interestingly, people who survive the withdrawal syndrome are often prone to a peculiar re-exposure phenomenon that I will discuss in future, i.e., they get sick upon re-exposure.)

The modern dwarf mutant variant of Triticum aestivum (that our USDA urges us to eat more of) contains greater proportions of gluten proteins compared to wheat pre-1970; glutens are the source of wheat-derived exorphins.

Incidentally, a drug company should be releasing a drug in the next year that will contain naltrexone, an oral opiate blocking drug, for a weight loss indication. They claim it is a blocker of the "mesolimbic reward system." I say it's a blocker of wheat exorphins.

The five most powerful heart disease prevention strategies

You've seen such lists before: 5 steps to prevent heart disease or some such thing. These lists usually say things like "cut your saturated fat," eat a "balanced diet" (whatever the heck that means), exercise, and don't smoke.

I would offer a different list. You already know that smoking is a supremely idiotic habit, so I won't repeat that. Here are the 5 most important strategies I know of that help you prevent heart disease and heart attack:

1) Eliminate wheat from the diet--Provided you don't do something stupid, like allow M&M's, Coca Cola, and corn chips to dominate your diet, elimination of wheat is an enormously effective means to reduce small LDL particles, reduce triglycerides, increase HDL, reduce inflammatory measures like c-reactive protein, lose weight (inflammation-driving visceral fat), reduce blood sugar, and reduce blood pressure. I know of no other single dietary strategy that packs as much punch. This has become even more true over the past 20 years, ever since the dwarf variant of modern wheat has come to dominate.

2) Achieve a desirable 25-hydroxy vitamin D level--Contrary to the inane comments of the Institute of Medicine, vitamin D supplementation increases HDL, reduces small LDL, normalizes insulin and reduces blood sugar, reduces blood pressure, and exerts potent anti-inflammatory effects on c-reactive protein, matrix metalloproteinase, and other inflammmatory mediators. While we also have drugs that mimic some of these effects, vitamin D does so without side-effects.

3) Supplement omega-3 fatty acids from fish oil--Omega-3 fatty acids reduce triglycerides, accelerate postprandial (after-meal) clearance of lipoprotein byproducts like chylomicron remnants, and have a physical stabilizing effect on atherosclerotic plaque.

4) Normalize thyroid function--Start with obtaining sufficient iodine. Iodine is not optional; it is an essential trace mineral to maintain normal thyroid function, protect the thyroid from the hundreds of thyroid disrupters in our environment (e.g., perchlorates from fertilizer residues in produce), as well as other functions such as anti-bacterial effects. Thyroid dysfunction is epidemic; correction of subtle degrees of hypothyroidism reduces LDL, reduces triglycerides, reduces small LDL, facilitates weight loss, reduces blood pressure, normalizes endothelial responses, and reduces oxidized LDL particles.

5) Make exercise fun--Not just exercise for the sake of exercise, but physical activity or exercise for the sake of having a good time. It's the difference between resigning yourself to 30 minutes of torture and boredom on the treadmill versus engaging in an activity you enjoy and look forward to: go dancing, walk with a friend, organize a paintball tournament outdoors, Zumba class, plant a new garden, etc. It's a distinction that spells the difference between finding every excuse not to do it, compared to making time for it because you enjoy it.

Note what is not on the list: cut your fat, eat more "healthy whole grains," take a cholesterol drug, take aspirin. That's the list you'd follow if you feel your hospital needs your $100,000 contribution, otherwise known as coronary bypass surgery.

Topping up your vitamin D tank

Now that my vitamin D replacement experience dates back nearly 5 years, I've been witnessing an unusual phenomenon:

The longer you take vitamin D, the less you need.

Let me explain. You take 10,000 units D3 in gelcap form. 25-hydroxy vitamin D levels, checked every 6 months, have remained consistently between 60 and 70 ng/ml. Three years into your vitamin D experience and 25-hydroxy vitamin D level rises to 98 ng/ml--an apparent need for less vitamin D.

So we cut your intake from 10,000 units per day to 8000 units per day. Another 25-hydroxy vitamin D level 6 months later: 94 ng/ml. We cut dose again to 6000 units, followed by another 25-hydroxy vitamin D level of 66 ng/ml.

This has now happened in approximately 20% of the people who have been taking vitamin D for 3 or more years. I know of no formal analysis of this effect, what I call the "topping up" phenomenon. Reasoned simply, it seems to me that, once your vitamin D "tank" is topped up (i.e., tissue stores have been replenished), it requires less to keep it full.

No one has experienced any adverse consequence of this topping up effect though it has potential for some people to develop toxic levels if 25-hydroxy vitamin D levels are not monitored long-term. In my office, I measure 25-hydroxy vitamin D levels every 6 months.

It means that long-term monitoring of 25-hydroxy vitamin D is crucial to maintain favorable and safe levels.

Thirteen catheterizations later

When I first met her, Janet couldn't stop sobbing. She'd just been through her 10th heart catheterization in two years.

It started with chest pains at age 56, prompting her first heart catheterization that uncovered severe atherosclerotic blockages in all three coronary arteries. Her cardiologist advised a bypass operation.

Six months after the bypass operation, Janet was back with more chest pains, just as bad as before. Another heart catherization showed that two of the three bypass grafts had failed. The third bypass graft contained a severe blockage that required a stent, along with multiple stents in the two now unbypassed arteries.

In the ensuing 18 months, Janet returned for 8 additional catheterizations, each time leaving the hospital with one or more stents.

Janet's doctor was puzzled as to why her disease was progressing so aggressively despite Lipitor and the low-fat diet provided by the hospital dietitian. So he had Janet undergo lipoprotein testing (NMR):

LDL particle number: 3363 nmol/L
Small LDL particle number: 2865 nmol/L
HDL cholesterol: 32 mg/dl
Triglycerides: 344 mg/dl
Fasting blood glucose 118 mg/dl
HbA1c 5.8%

Unfortunately, Janet's doctor didn't understand what these values meant. He pretty much threw his arms up in frustration. That's when I met Janet.

From her lipoprotein panel and other values, it was clear to me that Janet was miserably carbohydrate-sensitive and carbohydrate-indulgent, as demonstrated by the extravagant quantity (2865 nmol/L) and proportion (2865/3363, or 85%) of small LDL, the form of LDL particles created by carbohydrate exposure. Janet struggled with depression over the years and had been using carbohydrate foods as "comfort" foods, often resorting to cookies, pies, cakes, breads, and other wheat-containing foods for emotional solace.

It took a bit of persuasion to convince Janet that it was low-fat, "healthy whole grains," as well as comfort foods, that had led her down this path. I also helped Janet correct her severe vitamin D deficiency, mild thyroid dysfunction, and lack of omega-3 fatty acids.

Since meeting Janet and instituting her new prevention program, she has undergone three additional catheterizations (performed by another cardiologist), all performed for chest pain symptoms that struck during periods of emotional stress. All showed . . . no significant blockage. (Apparently, the repeated "need" for stents triggered a Pavlovian response: chest pain = "need" for yet more stents.)

In short, correction of the causes of coronary atherosclerotic plaque--small LDL, vitamin D deficiency, omega-3 fatty acid deficiency, and thyroid dysfunction--and Janet's disease essentially ground to a halt.

Imagine, instead, that Janet had undergone 1) a heart scan to identify hidden coronary plaque 5-10 years before her first heart procedure, then 2) corrected the causes before they triggered symptoms and posed danger. She might have been spared an extraordinary amount of life crises, hospital procedures, expense (nearly $1 million), and emotional suffering.

High blood pressure vanquished

Heart Scan Blog reader, Eric, related his blood pressure success story to me:

I'm 34 and have been battling chronic hypertension (systolic 150-200, depending on my anxiety levels) even with multiple prescriptions for over a decade now. I've seen four different cardiologists, all stumped as to what is causing my hypertension. First, they suspected coarctation of my aorta [a constriction in the aorta], but an angiogram determined blood pressure readings were the same on both sides of the narrowing.

The second angiogram performed last year to determine if my coarct had worsened determined that it had not, but that my aorta had calcium build up. The cardiologist was stumped because he told me he hasn't seen calcium in a patient so young. Needless to say, this scared me to death, with my wife being pregnant with our first child. I asked if it could be reversed and he didn't know so he sent me to get a Berkeley lab.

The Berkeley came back with LDL 91, HDL 41, Triglycerides 73, CRP 4.1, vit D 26. The doctors weren't very knowledgeable about explaining to me what these meant and how I could correct the low vit D and high CRP. They told me to follow the low-fat diet recommended by Berkeley. Well I've already tried the DASH diet and didn't like how I felt or my energy levels, so I didn't transition.

I was at a loss until I encountered your blog and it was truly a gift. It was a refreshing feeling to meet a knowledgeable Dr. who knew what I was going through and seems to truly care about reversing calcium in the heart (something I never got from my any of my cardiologists). With your blog I have an appointment to get a heart scan here in CO and take that number along with my Berkeley results and join Track Your Plaque.

For the past 2 weeks I've been following your advice by taking a D3+K2 supplement with Omega3 Fish oil and avoiding all grain, wheat, sugar and I'm already down 4lbs to 223.5lbs at 6'5" tall and my blood pressure readings have been 128/54 and 129/60 the past 2 days! With your help I may not have the dark future my father had: dead at 48 with a massive heart attack.

Stay on the look out because I look forward to telling you how I'm one of your top calcium losers!

Eric, Colorado


Conventional medical care fails at so many levels for so many people. While Eric's doctors were busy contemplating the next angiogram, they were neglecting several crucial aspects of his health.

It's really not that tough. But it can mean doing the opposite of what conventional "wisdom" tell us.

DHEA and Lp(a)

DHEA supplementation is among my favorite ways to deal with the often-difficult lipoprotein(a), Lp(a).

DHEA is a testosterone-like adrenal hormone that declines with age, such that a typical 70-year old has blood levels around 10% that of a youthful person. DHEA is responsible for physical vigor, strength, libido, and stamina. It also keeps a lid on Lp(a).

While the effect is modest, DHEA is among the most consistent for obtaining reductions in Lp(a). A typical response would be a drop in Lp(a) from 200 nmol/L to 180 nmol/L, or 50 mg/dl to 42 mg/dl--not big responses, but very consistent responses. While there are plenty of non-responders to, say, testosterone (males), DHEA somehow escapes this inconsistency.

Rarely will DHEA be sufficient as a sole treatment for increased Lp(a), however. It is more helpful as an adjunct, e.g., to high-dose fish oil (now our number one strategy for Lp(a) control in the Track Your Plaque program), or niacin.

Because the "usual" 50 mg dose makes a lot of people bossy and aggressive, I now advise people to start with 10 mg. We then increase gradually over time to higher doses, provided the edginess and bossiness don't creep out.

The data documenting the Lp(a)-reducing effect of DHEA are limited, such as this University of Pennsylvania study, but in my real life experience in over 300 people with Lp(a), I can tell you it works.

And don't be scared by the horror stories of 10+ years ago when DHEA was thought to be a "fountain of youth," prompting some to take megadose DHEA of 1000-3000 mg per day. Like any hormone taken in supraphysiologic doses, weird stuff happens. In the case of DHEA, people become hyperaggressive, women grow mustaches and develop deep voices. DHEA doses used for Lp(a) are physiologic doses within the range ordinarily experienced by youthful humans.

No more cookies

Jeanne enjoyed her Christmas holidays. She especially liked sharing the cookies she made for her grandchildren, sneaking 2 or 3 every day over a couple of weeks. On top of this, she enjoyed the Christmas candy, egg nog, leftover stuffing and cranberry sauce, topped off with a night of nutritional debauchery on New Year's Eve.

Lipid panel in October:

Total cholesterol 146 mg/dl
LDL cholesterol 72 mg/dl
HDL cholesterol 64 mg/dl
Triglycerides 49 mg/dl

Lipid panel in early January:

Total cholesterol 229 mg/dl
LDL cholesterol 141 mg/dl
HDL cholesterol 59 mg/dl
Triglycerides 147 mg/dl


I call the holidays The Annual Wheat and Sugar Frenzy. It's the carbohydrates, especially those from products made of wheat and sucrose, that caused the marked shifts in Jeanne's lipid patterns. Let's take each parameter apart:

--Triglycerides go up due to de novo lipogenesis, liver conversion of carbohydrates into triglycerides. Triglycerides enter the bloodstream as VLDL particles which, in turn, interact with LDL and HDL.

--LDL goes up because carbohydrate exposure increases VLDL, followed by conversion to LDL. The triglyceride-rich LDL created is converted to small LDL particles. Had we measured small LDL changes in Jeanne, we likely would have measured something like an increase (by NMR) from 800 nmol/L to 1600 nmol/L, a carbohydrate effect.

--The increased VLDL also makes HDL triglyceride-rich, cause more rapid degradation of HDL particles. (It also makes them smaller, like LDL.) Given sufficient time (a few more months), HDL would drop into the 40's.

--Total cholesterol changes reflect the composite of the above numbers. (Total cholesterol = LDL cholesterol + HDL cholesterol + Trig/5) (Note that, as HDL drops, so will total cholesterol; that's why this value is worthless and should be ignored.)

So don't be surprised by the above distortions after a period of carbohydrate indulgence. Although your unwitting primary care doc will see such changes as opportunity for Lipitor, it is nothing more than the cascade of effects from a carbohydrate-driven distortion of lipoproteins.

How to become diabetic in 5 easy steps

If you would like to become diabetic in as short a time as possible, or if you have someone you don't like--ex-spouse, nasty neighbor, cranky mother-in-law--whose health you'd like to booby trap, then here's an easy-to-follow 5-step plan to make you or your target diabetic.


1) Cut your fat and eat healthy, whole grains--Yes, reduce satiety-inducing foods and replace the calories with appetite-increasing foods, such as whole grain bread, that skyrocket blood sugar higher than a candy bar.

2) Consume one or more servings of juice or soda per day--The fructose from the sucrose or high-fructose corn syrup will grow visceral fat and cultivate resistance to insulin.

3) Follow the Institute of Medicine's advice on vitamin D--Take no more than 600 units vitamin D per day. This will allow abnormal levels of insulin resistance to persist, driving up blood sugar, grow visceral fat, and allow abnormal inflammatory phenomena to persist.

4) Have a bowl of oatmeal or oat cereal every morning--Because oat products skyrocket blood sugar, the repeated high sugars will damage the pancreatic beta cells ("glucose toxicity"), eventually impairing pancreatic insulin production. (Entice your target even further: "Would you like a little honey with your oatmeal?") To make your diabetes-creating breakfast concoction even more effective, make the oatmeal using bottled water. Many popular bottled waters, like Coca Cola's Dasani or Pepsi's Aquafina, are filtered waters. This means they are devoid of magnesium, a mineral important for regulating insulin responses.

5) Take a diuretic (like hydrochlorothiazide, or HCTZ) or beta blocker (like metoprolol or atenolol) for blood pressure--Likelihood of diabetes increases 30% with these common blood pressure agents.

There you have it! Perhaps we should assemble a convenient do-it-yourself-at-home diabetes kit to help, complete with several servings of whole grain bread, a big bottle of cranberry juice, some 600 unit vitamin D tablets, a container of Irish oatmeal, and some nice bottled water.
Atkins Diet: Common errors

Atkins Diet: Common errors

No doubt: The diet approach advocated by the late Dr. Robert Atkins was a heck of a lot closer to an ideal diet than the knuckleheaded advice emitting from the USDA, American Heart Association, American Diabetes Association, and the Surgeon General's office.

But having just spent a week with Atkins low-carbers, here are some common errors that I see many make, errors that I believe have long-term health consequences, including impairment of weight loss.

Excessive consumption of animal products--Non-restriction of fat often leads to over-reliance on animal products. Higher intakes of red meats (heme proteins?) have been strongly associated with increased risk for colon and other gastrointestinal tract cancers. It is not a fat issue; it is an animal product issue. We should consume less meat, more vegetables and other plant-sourced foods.

Consumption of cured meats--Cured, processed meats, such as sausage, hot dogs, salami, bologna, and bacon, have a color fixative called sodium nitrite, an additive that has been confidently linked to gastrointestinal cancers. Risk is likely dose-dependent: The more you ingest, the greater the long-term risk.

Overconsumption of dairy products--Dairy products, especially milk, yogurt, cottage cheese, and butter, are potent insulinotropic foods, i.e., foods that trigger insulin release. There can be up to a tripling of insulin (area-under-the-curve) levels. This is not good in a world populated with tired, overworked pancreases, exhausted from a lifetime of high-carbohydrate eating.

Too many calories--While I agree that "a calorie is a calorie" and "calories in, calories out" are faulty concepts, I have anecdotally observed that long-time low-carbers often trend towards unlimited consumption of food, a phenomenon that seems to result in weight gain, especially in the sedentary. I wonder if this is a reflection of the insulinotropic action of dairy products and other proteins, compounded by the poor insulin responsiveness that develops with lack of physical activity. Factor into this conversation that lower calorie intake extends life, probably substantially (Sirt-2 activation and related phenomena, a la resveratrol). If lower calorie intake extends life, unlimited calorie intake likely shortens life.

Please don't hear this as low-carb bashing--it is not. It is a call to improve diets and not stumble into common traps that can impair heart health, weight loss, and longevity.

    Please could you provide links to the interventional controlled (not observational) studies that have shown a link between eating meat and cancer risk, that separate the effect from eating junk food, and the fact that vegetarians are more likely to eat healthily in general than meat eaters due to the widespread and incorrect belief that saturated fat is harmful to health.

    Also, could you explain lack of cancer in traditional tribal societies with a high meat intake? You would need to do this before stating that meat intake necessarily increases cancer risk.

    Hi doc,

    Great blog. How do you explain the Inuit, Masaai, Komi (Siberia), Native American and similar cultural groups whose diets seemed to subsist primarily on animal products? ie. including my ancestors.

    Perhaps its an emphasis on wild/grass-fed/raw dairy(or as close to) animal products as opposed to the grain-fed animal products which encompass the majority of the US that you need to be addressing?

    Thanks.

    Great diet, and yes, it seems that we should talk about healthy eating instead of weight loss or diets. Anyway the purpose of any diet is to move your eating habits to new healthy level.

    Just on the nitrate/nitrite subject: as far as I know nitrate is a naturally occurring compound and the human exposure to it is mostly through  consumption of vegetables, and to a lesser extent water and other foods...

    I would say there are 3 primary pitfalls of low-carb dieting:

    1) Being too low in carbohydrates - being in ketosis is anti-metabolic and induces insulin resistance, and probably why Atkins suggested that his diet "tends to shut down the thyroid."  

    2) Too much protein - this strains the thyroid as well, and encourages gluconeogenesis, which is also problematic - especially when in ketosis and insulin resistance is extreme.  

    3) Extremely high in omega 6 polyunsaturated fat.  Eating a low carb diet with lots of pork fat, chicken skin, peanut butter, and nuts - the typical standbys of many low-carb dieters, provides an astronomical amount of omega 6.

    By my best guesses, I was consuming 15+ grams of omega 6 while on a low-carb diet.  I've since cut that back to less than 3 grams per day and the change has been dramatic.  Of course the 400 grams of carbs per day helps too.

    Dr. Davis,
    Thank you for this post.  I'm certainly culpable of the "common errors" you mention.  I find that making daily decisions on what to eat difficult. I want to eat healthy and have some variety. Here's the question.  What do you eat?  What did you have for breakfast this morning?  What did you eat last night?  What do you keep in the fridge and on the counter to make following your dictates easier.
    I don't want to over-think it but all this information is overwhelming.  I feel like a scientist and my body is the research subject.
    Thank you for your blog.  I've learned a lot but need some direct guidance.
    Sincerely,
    Dana Law

  • Tim

    Have you really read the meat leading to cancer literature carefully or do you just think it's like that? Others like Gary Taubes and Eades (who I really trust when it comes to research) have found no evidence that meat cause cancer.

    On sodium nitrate, I totally agree. I get so mad when I'm walking in the grocery stores. All meat has sodium nitrate added. Grrr.

    I share your thought about dairy. But do you really mean that butter triggers insulin spikes?

  • Daniel

    3/18/2010 3:11:55 PM |

    Most nitrite is form your own spit and originally ingested by eating vegetables.  

    I believe the epidemiological studies (which also typically find fat to have bad associations...) have more to do with a lack of fruits/vegetables/polyphenols than anything that is bad about meat.  

    Also, I don't think glycemic index or the insulinotropic nature of certain proteins matters one lick for people that are healthy.  I can eat a boiled potato for breakfast without my blood sugar breaking 100... I don't think diabetes is an overuse injury - more likely, it is cause by damage to the liver and then pancreas from PUFA and fructose overconsumption.  

    I think Matt Stone is correct about the top three problems with Atkins.

  • Lena

    3/18/2010 3:17:06 PM |

    If you're really concerned about your nitrite intake, watch your celery, arugula and spinach (and many other vegetables) consumption, too. Nitrites galore. Though it's not nitrites and nitrates in and of themselves that are linked to cancer, it's the nitrosamines that can form from them.

    Sodium nitrite isn't primarily a colour fixative, it's a an anti-bacterial agent. Meats cured with sodium chloride only have to be done quite carefully to avoid botulism. Nitrite has been used since the 16th century to preserve meat. Modern cured meats also add sodium ascorbate, and ascorbates have been shown to inhibit nitrosation reactions and thus the nitroamine level in these cured meats is usually at undetecable levels.

    Nitrites are produced in our mouths from bacterial reactions to the nitrates in food and water, and at least 70% of our dietary nitrite comes from this salivary nitrite (which came from our food and water). The nitrites and nitrates we then ingest are mostly either excreted fairly promptly or used to make nitric oxide. Human gastric secretions have a pH which isn't condusive to nitrosamine formation, and also include ascorbates which reduce nitrosamine formation, and keeping one's vitamin C at good levels will also have an effect. People with achlorhydria will obviously be more susceptible to nitrosamine formation. But interestingly, there are studies which now suggest that nitrite consumption is a good thing: http://www.ncbi.nlm.nih.gov/pubmed/20005970 - and branched-chain amino acids are also suggested as suppressing the effect of nitrosamines. However the amount of nitrosamines you get from smoking is definitely Not Good, and no amount of ascorbate will ameliorate it.

    So, a good intake of nitrates and nitrites primarily through vegetables, some fruit, and some cured meat is good: the vegetables and fruit contain ascorbates as does your body, and most of hte meat should have it added also, minimising the formation of nitrosamines, leaving your body to get on with making use of the nitr*tes to make needed nitric oxide. (Oral nitric oxide/arginine supplements are rubbish though - the studies showing their benefit used intravenous/injected supplement.)

    Personally, I'll take nitrites over botulism, thanks.

    Hmmm, I've never been on a cruise, but if I did go on one, I'll bet I'd have to eat somewhat differently than I do at home, regardless of the carb count.  Between not having access to the pastured bison and wild game, raw dairy, "backyard" eggs, and organic CSA produce subscription, and so on that make up most of my family's daily diet, and no access to a kitchen, my meals on a cruise would hardly be representative of my usual diet.  

    I'll bet LC cruisers are as prone to anyone when it comes to the excesses of endless supply of prepared foods on cruises, but I'm not sure we can assume that's the way they always eat.  Most people  eat somewhat differently on vacation, whether it's because they are on somewhat of a "diet vacation", or because they have to make the best of what's available.  When I was on vacation in Italy I had a gelato every day, but I certainly don't do that at home (it was a conscious decision to take a slight vacation from my diet and enjoy a local specialty for a limited time).  And I've been places where it was impossible to get eggs cooked in real butter instead of the ubiquitous "griddle grease" hydrogenated veggie oil, let alone pastured eggs and humanely produced bacon (seriously, we breakfasted at a tiny roadside diner outside Twenty-Nine Palms that had NO butter on the premises).  

    And not all LC eaters are following an Atkin's diet plan, though I understand the Atkins label has become be a generic term for LC eating.  I've read an Atkins book (as well as at least a half dozen other LC diet books).  I eat LC (& GF now) but I've never followed specifically an Atkin's diet plan, nor do I describe myself as at Atkin's dieter.

    I think the points you make point out that even on low carb, people can and do still rely on far too much industrial food.  It's convenient and it's everywhere (hard to avoid, esp when dining away from home).  Frankly, one of the reasons cruise vacations hold little appeal to me is the idea of having to nothing to eat all week but cr@p industrial food, no matter how talented the chefs may be at making it look and taste good.   I may be making a sweeping assumption, but somehow I don't imagine that cruise chefs are simmering their own bone broth stocks, curing charcuterie themselves, and making their own cheese (or even sourcing from small artisan vendors  very much).    I'd be extremely surprised if cruise ship food ingredients weren't offloaded from US Food tractor trailer trucks.  That's what I've seen at many land-based resorts.  When I travel,  as much as possible, I want to try the local traditional foods and specialties, prepared as authentically as possible.  That might mean eating more of something than usual (and less, too).

    Isn't it also an Atkins diet error that low-carb eaters tend to be on a constant and frantic quest for processed fake food items that are pretend substitutes for the food that got them in trouble in the first place?  And many of them have made Jimmy Moore, a huge hawker of low-carb substitutes and a less-than-successful low-carber, their role model.  

    I noticed on Swedish physician Dr. Andreas Eenfeldt's blog that his description of his experience on the cruise was that "[t]he big difference with Sweden is that many are fond of low-carb versions of traditional junk food, sugar, and so. Low carb cake, low carb icecream, low carb potato chips, diet sodas ... In my eyes seemed to just those participants who ate such did not have the same persuasive power of the diet. To put it nicely. Perhaps it was the roundest of them all, the man [Andrew DiMino -- Carbsmart.com?] who handed out the various "low carb" products that are advertising for his company. [Google translation]

    People I know who have been totally unsuccessful on Atkins have gleefully loaded up on "substitutes" that probably have derailed them.  And the Atkins company that sells this crap will forever keep the Atkins mantra from the gaining the credibility it probably deserves.

    Bill you said:

    "Excessive consumption of animal products--Non-restriction of fat often leads to over-reliance on animal products. Higher intakes of red meats (heme proteins?) have been strongly associated with increased risk for colon and other gastrointestinal tract cancers. It is not a fat issue; it is an animal product issue. We should consume less meat, more vegetables and other plant-sourced foods."

    I don't think this is true Bill. As far as I'm aware, there is no good evidence to support protein as cancer causing. Dr. Eades has debunked this on his blog.

    Ditto what Tim said. My understanding is that it's the whey in dairy that is insulinogenic (tho it's a bit like the glycemic index ... it depends on when and what you eat it with).

    Butter should not be as big a problem. One of my go-tos is ghee from grass-fed cows. The small amount of milk solids left in butter are removed when ghee is made.

    If you cut out animal protein, dairy, and carbs, there's not much left to eat.

    The protein sources favored by vegetarians, beans, rice, and grains, make blood sugar increase too much for people with diabetes.

    One can not live on tofu and fat alone, and anyway some people say too much soy is not good.

    I don't know why people have a prejudice against dairy. See this:

    http://care.diabetesjournals.org/content/29/7/1579.full

    If you have a diabetic tendency, it means your beta cells aren't producing enough insulin, so a food that helps them along is good.

    Too many calories on a high fat diet? Good luck keeping that up. I can't get 2000 most days. Too full.

    Why were there traditional societies that used dairy as a staple yet were free of CVD and diabetes, including the super long lived people on the border of Eastern Europe and Central Asia?

    Copy and paste the above argument for "eating too much meat."

    Low carb may not be for everyone, but the biggest problem with some low carbers is probably too much n-6 from processed meat. Lots of nuts aren't that good for you either.

It is not all about meqat meat meat or even high protein. And as much as I enjoy your blog- you still have a huge fear of fat. With Atkins I have improved my metabolic problems.

  • Helen

    3/18/2010 7:12:05 PM |

    I've been concerned to learn, here and elsewhere, that dairy products are insulinogenic, particularly since I can't seem to manage a reasonable diet without a fair amount of them.  (Nuts don't do well with me, soy is a no-go, I can only eat so much meat, my family has egg-allergy issues, and the fish that is non-contaminated, sustainably caught, not-BPA-canned, not-fed omega-6 and dioxin-laced stuff in a disgusting fish farm, is wicked expensive and logistically impossible to get fresh for my family more than once a week....)

    On the other hand, there are several dairy-reliant cultures that are quite long-lived and healthy, and dairy-consuming people in our own culture tend to be healthier than non-dairy eaters.  So maybe something mitigates the insulin question with dairy.  Just saying.

    In the end, you have to eat something, and sometimes reading this blog I feel I can't eat anything.  Like Dana Law, I'd like a better picture of what an ideal, or at least acceptable, day's or week's diet would look like from your point of view.

    3/18/2010 8:56:12 PM |

    I've followed Atkins for these last three years, losing 80lbs in the process, so am quite familiar with what's permitted and not.

    Atkins did not recommend consuming any milk, nor was much yogurt or cottage cheese permitted. Hard cheese, cream cheese and heavy cream are allowed, but the Atkins diet permits less than 2-3 oz per day.

    Butter is allowed liberally, but is 100% fat so can't be very insunlinotropic, if at all.

    Because I raise dairy goats, until three years ago, I drank goat milk freel.  Now I never drink it, though I do have a glass of very sour kefir now and then, after the probiotics have cultured most of the lactose into lactic acid.  The kefir I drink is very tart. Most people don't like it that sour. lol

    The "Atkins is High-Protein" myth is often bandied about by anti-low-carb groups. I track my daily intake on FitDay and it's usually about 15-18% protein, 65-70% fat, and 10-20% carbs... pretty much what Atkins recommended; even 20% protein is not especially high protein.

    My carbs come mostly from eggs, green vegetables, heavy cream for coffee, berries and other LC fruit, and certain nuts and seeds, like flax.  Peanut butter is very carby, and not freely allowed in Atkins.

    I recommend reading the old Atkins book to understand what his diet really contains. Read the 1972 version, as the newer books (after 1999) were changed by Atkins Nutritionals to allow low-carb junk food that they conveniently sell.

    I don't want anybody to hear "don't eat meat" here.

    I think that you should eat meat. I am a former vegetarian and I don't particularly like meat. Despite this, I do feel that humans are meant to be carnivorous. I just don't believe that piling your plate high with animal products several times per day is the ideal way to eat.

  • Haggus

    3/18/2010 9:58:20 PM |

    Dr. Davis, you sure it was "Atkins low-carbers" you were with?

    "Excessive consumption of animal products"

    At least with DANDR 2002, as you go up higher on the rungs, meat is replaced somewhat by veggies.  Personally, I eat around 200g of meat per day.  Of that, less than 90g is red meat (the rest is fish.)

    "Consumption of cured meat"

    I love bacon as much as the next guy, but in even Dr. Atkins stated in DANDR 20002 that one should "try to avoid meat and fish products cured with nitrates, which are known carcinogens."

    As for dairy, it's not taboo but still has to be fitted into the carbs you are allowed per day.

    This is the second blog post since the trip you have me scratching my head.  I hit your 60-60-60 markers using oat bran all the while being IGT and sporting an A1c of 4.8%.  (And before anyone asks, in DANDR 2002 Dr. Atkins mentions oat bran to bring down your cholesterol levels.)

    Try to do that for an extended period of time. I lasted about 2 weeks. Now I have a very small meaty breakfast, and a modest size meaty dinner, and I'm STUFFED. Been like this for years. Can't eat lunch-not hungry.

    You prefer plant foods which is great, but you're not in a carnivore's shoes. From our perspective, what you say is rather silly because many of us actually worry about not getting enough calories! Fat is filling. I'm a 6ft, 165 lb male and I can barely get 2000 calories I feel so full.

    Here's a good take on the conventional "wisdom" of nitrates: http://junkfoodscience.blogspot.com/2008/07/does-banning-hotdogs-and-bacon-make.html

    Matt:

    "Being too low in carbohydrates - being in ketosis is anti-metabolic and induces insulin resistance, and probably why Atkins suggested that his diet 'tends to shut down the thyroid.'"

    I generally find your thoughts to be spot-on, so there's no need to manipulate Atkins' quote to enhance your point.  What he said was that dieting in general tends to shut down the thyroid.

    "[P]rolonged dieting [including ‘this one’] tends to shut down thyroid function."

  • sonagi92

    3/18/2010 11:25:42 PM |

    I knew that dairy was insulinotropic, but like Emily, I was surprised to see butter on the list as butter is mostly fat, and clarified butter entirely fat.  As I understand, it is protein-rich foods like beef, chicken, and fish, that provoke unexpectedly high insulin responses, so I thought it was either the sugars or the protein in dairy, not the fat, that spiked a rise in blood sugar.  Is butter really insulinotropic like other dairy products containing lactose sugars and proteins?

  • sonagi92

    3/18/2010 11:39:43 PM |

    Another comment about dairy and weight gain:

    I have noticed that melted cheese in particular - a warm, creamy fat with some carbs and protein - is highly palatable.  Full-fat yogurt, whipped cream, and guacamole are similarly irresistible.  I could not consume more than a couple tablespoons of olive oil yet have no trouble gobbling down a few slices of cheese melted onto a piece of chicken or beef.  I'm trying to shave off 5 more pounds to reach my goal, so I've given up all dairy except for clarified butter, which I use to saute veggies.  Will see if this works.

Should slimness be a goal every low-carber can meet (apart from all the other health benefits)?

    How high is "too high?" I say this not to be a smart aleck or to overlook the wisdom in "you'll know it when you see it," but this is a bit too vague to be of much use.

    Clearly a largely plant-based diet supplemented with a decent amount of animal protein will trump loading up heavily on animal products to the exclusion of plant-based foods. But there's far too many vague generalizations being bandied about by so-called dietary experts these days and not a lot of concrete recommendations that can be tailored to fit a person's unique context.

    I would also like to see a typical day in the life of Dr. Davis.

    Anon-  Yes, they mean a % of total calories.  You can figure it this way:

    1g Protein = 4 cals
    1g Carb = 4 cals
    1g Fat = 9 cals

    So if a person eats 2000 cals/day and 18% was from protein, then that person ate approximately 360 cals of protein.  Divide 360 by 4 and you get 90 grams of protein.

    I agree that there are many low carbers who follow their eating plan less than optimally. I see them posting on the low carb forums I follow. But as one who was also on the cruise, I don't think you can really equate cruise eating with what people eat on a normal day-to-day basis!

    I had resolved to eat only "real food" on the cruise, as I almost always do at home, and I had resolved not to snack. And I was pretty good about my resolve. I didn't snack, ate only three meals a day, avoided the flour, sugar, even the sugar-free cheesecake and other things provided.

    But did I eat exactly the way I would eat at home? No, I didn't. I undoubtedly ate more than I would have eaten at home, and probably certainly more protein sources than I would have eaten at home. The last night of the cruise I even broke down and had one of the sugar-free margaritas, and I had a half glass of red wine at the comedy show.

    And I'm sure my PUFA intake was higher than I would normally like. We had no control over how foods were prepared in the kitchen after all, or very little.

    But this was 5 days out of my life, not a lifetime of eating. Smile I didn't gain any weight on the cruise and indeed have even hit a new low this week since being back. Overall I've lost more than 100 pounds.  

    I'm not convinced of the meat/cancer link either - though too much protein raises my blood sugar so I don't normal OD on protein much. I was never a vegetarian but often thought I could have gone that way as I'm not all that crazy about meat. But now I have an "It's them or me" attitude and look for meats I  enjoy better - just not too much.

    Apparently Matt Stone has challenged my son to try out a super-low-calorie, essentially fat-free diet, based on 1930s research by Evans and Strang, and I'm following his progress with interest. But at the moment it's not for me. I still love my butter and coconut oil.

    But we are all so different, and what works for one may not work well for another. But I wonder how many low carbers eat at home the same way they ate on the cruise?

    Anon said: "Whenever I read this sort of thing, I get confused. 15-18% of WHAT? the total calories? and if so then how do I translate that percentage into actual amounts (like grams or ounces?)"

    Percentages of my daily food intake. I used percentages because everyone has a different calorie ceiling where we stop losing weight. The ceiling calorie limit usually changes as you lose weight; but the percentage of Protein, Fat and Carbohydrates should remain the same.

    My daily calorie limit is now around 1500 calories; when I weighed 80 lbs more, it was closer to 2000 calories; and at 2000 calories back then I was losing 3-4 lbs a week.  Either way, the grams/oz of Potein/Fat/Carbs that I eat probably won't relate well to you; but percentages can and will.

    By the way, I use a food-tracking program called FitDay, that calculates your food entries into P/F/C, and into grams/oz and percentages, and also gives daily vitamin/mineral counts as well as for individual foods.  It's really quite interesting to compare the nutrition counts of different foods; that way you can see what's really worth eating.  Meat contains a lot more than just protein... it has a lot of essential vitamins and minerals, actually.

    FitDay is free online, but the purchased version is much more convenient; I paid $25 three years ago and consider the money well spent.

    You should track your own food intake to see for yourself what percentages your current diet contains... you might be surprised. Food tracking, whether through FitDay or some other program, is the single most useful thing that helps keep me on track.

    Re Anonymous and "percentages."  This drives me crazy too.  Without a total daily calorie count, percentages are meaningless.  So what if I eat "10%" carbs, if I am noshing on 6000 calories a day?

    To answer your question: yes, you do have to do some simple math.  First, figure out the number of calories in the given percentage, using a hypothetical total daily caloric intake.  40% of 2,000 calories, for example, would be 800 calories.  A carb has roughly 4-5 calories per gram, so that would equate to around 200 grams of carbs.  Protein is similar.  Fat, on the other hand, has 9 calories per gram.  So those 800 calories would be slightly less than 90 grams of fat.

    Once you start doing it, it gets easier.  Practice on food labels!

  • HSL

    3/19/2010 8:11:21 PM |

    Anon - most food values are given as a % of calories.  For example if you are eating 2000 calories/day of which 70% is fat, then you're eating about 155 gms of fat per day (2000 x 0.70 = 1400/9 = 155 gms). Fat has about 9 calories/gm; carbs & protein each have about 4 calories/gm.

    As for "...15 to 18% of what" that would depend on what you're eating.  Three ounces of white fish (raw) has about 16 gms of protein; 3 oz of beef chuck (raw) has about 28 gms of protein.

    I was on the cruise and yes, many of the cruisers were overweight.  Some are just starting a low carb lifestyle, and some are not.  I personally have lost over 150 lbs on low carb and maintained that loss for nearly 2 years now.  I consider that a success, however, I am not thin by any means and am working on about 50 more lbs.  I took the advice from many of the speakers, Dr. Davis included, and have worked it into my daily routines.  As a registered nurse, I am aware of nutrition both mainstream and low carb.  I do my research.  I try to eat cleanly most of the time.  Life interferes sometimes, much as is does for anyone who is human and as I know it has for some of the individuals who were on the cruise.  I do believe individuals who are or have been morbidly obese are vastly different from your average American with 30 lbs to lose.  Everything happens on a grander scale.  We lose weight bigger and gain weight bigger.  All I know is I've lost 100+ lbs using the Standard American Diet--twice.  Within a year I gained it back--twice.  Finding a low carb diet has saved my life.  I eat in normal portion sizes, I maintain. Is it for everyone? No.  Is it the only way? No.  But it is one way that works for many people who really need it.  

    Thanks Dr. Davis, for your presentation.  I truly enjoyed it.

    "Higher intakes of red meats (heme proteins?) have been strongly associated with increased risk for colon and other gastrointestinal tract cancers."

    Really? Strong association? If that's true, then how do you explain this?:

    Hilary, I have not formed an opinion one way or the other on this issue yet, but the study you cite was "Supported in part by the Cattlemen's Beef Board, through the National Cattlemen's Beef Association, and the National Pork Board."

    Re my question as to how to translate percentages of protein, fat and carbs into grams, I should've have asked my trusted friend "google" instead of taking up someone's time here. So please forgive me.

    But Thanks! to those who responded. Your explanations were very helpful.

    Meanwhile, I found a site which will do all that computation for me and thought I'd pass it on.

    Hi I was on the cruise and thoroughly enjoyed it. Sue, Yes I am overweight according to my BMI of 29, I was on the cruise the first year by the second i was 20 pound lighter by the time I got on this years cruise since last year I have lost 54 pound. Yes I am still as you say overweight but I am doing something about it. Sorry I wasn't "normal" for this year but I will be for next year. Snacks were handed out but the message was clear that these are treats and a preferable treat than something high carb and sugar loaded. There were new people there and others who have been doing it a while and of those we are all less than when we started. We had some excellent speakers i.e. Dana Carpender who spends her life educating us how to make foods using our own ingredients she even said you can put weight on eating low carb as we still can make the wrong choices. We all have the same problem with food do we not but we are prepared to be educated by the fabulous speakers who went to help us and gave their time freely to pass on their knowledge.

    A big big thank you to them and you Dr Davis

    Ailsa who came one the cruise all the way from the UK.

    I've been reading your blog for a couple years and really enjoy doing so. I think you've got it wrong on the Atkins diet, though. I don't know where you got your information and I'm pretty sure you didn't read the books. Milk and yogurt aren't on the "diet". Atkins also told you to not eat cured meats. As far as calories are concerned, Atkins also told people to not eat too much! So... I'm having a lot of difficulty with this article in particular & wanted to pipe up. I'll go back to readin' the rest of your blog now. Thanks for all your efforts in keeping this blog up and running. -- Mike

    Dr. Davis, have greatly enjoyed your insights on this blog over the year. Have had your book for a couple of years. Have noticed great benefits from your vitamin D recommendations. When is your updated Track Your Plaque book coming out? I thought it was coming out toward the end of last year? Any ETA on it? Very interested in seeing your recommendations as it relates to diet? Typical recommended breakfasts, lunchs, and dinners?

    This seems consistent with Ray Peat's advice as far as meat meat is concerned- he recommends balancing meat intake with gelatin so as to not get too much iron (hemeprotein afterall) as well as the fact that it has a less inflammatory amino acid profile (muscle is high in tryptophan and histidine wheras gelatin has no tryptophan and lots of glycine and proline...)

    Also he mentions that he always drinks coffee when he eats red meat so as to block iron overload even more!

    Of course he has no problems with milk, butter and cheese consumption but prefers the latter b/c curds have a better amino profile than whey.

    Over the years, I've looked closely at the studies associating red meat with colorectal cancer, and it appears to be impossible from them to separate the effects of modern meat production practices from that of the meat. In other words, it is as likely as not that what's wrong with the red meat is what we put into it, and how it is grown, versus any attribute of the meat itself.

    However, whatever the cause of the problem, it pays to at least limit consumption of red meat that you buy in a supermarket.

    Hi Dr Davis,

    Thanks for sharing your comments. I am a big Atkins Diet follower, and we all need to remind ourselves to keep the intake of "processed" meat & foods to a minimum. Vegetables are a good way to go! Thanks for providing us <a href ="http://atkinsdietinformation.blogspot.com>Atkins Diet</a> followers with such relevant and important information

    Cheers,

    I think it's bizarre to associate ANYONE'S eating habits on a cruise with what their day-to-day life is like.

    My normal food would not be available on a cruise: homemade yogurt and kefir made from fresh raw whole milk mixed with berries, pastured eggs with dark yellow yolks cooked in pastured butter, pastured meat, fresh organic fruits and vegetables, homemade chocolate made with coconut oil, cocoa, almonds and stevia... I don't see a cruise line providing food like this.

    So, I'd probably do sugar-free cheesecake too, or wind up overeating fresh fruit, just cause there'd not be any of my food there.

    When I travel, I do Wendy's burgers using the lettuce as a bun if hitting a drive-through or really crappy salad bars with not much beyond iceberg lettuce.

    Sometimes, you do the best you can with the circumstances... cause to eat really WELL, you pretty much need a kitchen.

    Really some truth to the fact that people from Mediterranean areas are seldom obese despite eating a very high fat diet? Did science get it all wrong before? Was there a national conspiracy to force people to eat boring, healthy foods? Thanks for your good suggestion.

    I haven't eaten meat or dairy in long time. Humans don't need meat or dairy. I think meat is disgusting and I'm glad I don't have to eat it. I've seen meat-eaters B-12 deficient, so this shows eating meat doesn't necessarily make someone sufficient in B-12. Methylcobalamin B-12 works great. Eating red meat apparently increases colon and breast cancer risk. I think meat was meant to be an option, just like grains or legumes. Humans were designed to survive on many different things. Plant foods are affordable and bearable for me - meat is not.

    Overconsumption of dairy products--Dairy products, especially milk, yogurt, cottage cheese, and butter, are potent insulinotropic foods, i.e., foods that trigger insulin release. There can be up to a tripling of insulin (area-under-the-curve) levels. This is not good in a world populated with tired, overworked pancreases, exhausted from a lifetime of high-carbohydrate eating.

    hey guys,
    you out there had some great conversations that help me learn a lot from your, atkins diet, "slow-burn" discussions, meat consumption and being vegetarian.

    Nice exchange of great ideas, keep going guys and thanks Dr. Davis.

    What do you make of this 'physiological insulin resistance' and its role in creeping weight gain on too low carb

    Hi, Lance--

    I've not heard this argument before. If you've got the references for the studies showing this effect, I'd be happy to take a look.

    In real life, I've not seen this play out. People who restrict carbs, lose visceral fat, drop HbA1c, glucose, and insulin. Maintaining the diet does not, over the years, allow recrudescence of the phenomena of insulin resistance.
