No more Lovaza

That's it: I will NEVER ever write another prescription for Lovaza.

I actually very rarely write a prescription for Lovaza, i.e., prescription fish oil. But this was the last straw.

I advised a patient that we've had good success using high-doses of fish oil to reduce lipoprotein(a), Lp(a). 6000 mg per day of the omega-3 component (EPA + DHA) from fish oil reduces Lp(a) in 60% of people after one year. (Recall that Lp(a) is the most aggressive known lipid-related cause of heart disease.)

The two preparations I generally suggest are either the very affordable Sam's Club Members Mark Triple-Strength Fish Oil with 900 mg EPA + DHA per capsule: 7 capsules per day. Another great product (my personal favorite because of its extreme purity--it doesn't even smell like fish oil): Pharmax Finest Pure Fish Oil with 1800 mg EPA + DHA per teaspoon: 3 to 3 1/2 teaspoons per day.

Both preparations work great and are quite affordable, given the high dose. For the Sam's Club preparation, it will cost around $30 per month, while the Pharmax liquid will run around $49 per month.

Well, the woman's husband insisted on a prescription for Lovaza. One Lovaza capsule contains 784 mg EPA + DHA per capsule: 7 to 8 capsules per day.

Here are some prices for Lovaza from online pharmacy discounters:
Prescription Giant: $78.99 for 30 capsules ($2.63 per capsule)
Planet Drugs Direct: $135 for 100 capsules ($1.35 per capsule)

These are lower than the prices I obtained in past by calling local pharmacies in my area, quite a bit lower, in fact.

Filling the Lovaza prescription at Prescription Giant will therefore cost $552.93 to $631.92 per month; at Planet Drugs Direct it will cost $283.50 to $324.00 per month. At local pharmacies, a similar 7 to 9 capsules Lovaza per day will cost upwards of $800 to $900 per month.

The patient's husband insisted on the Lovaza prescription because he knew that his insurance would cover it. When I pointed out that this was a large cost that would have to be borne by others in their healthcare premiums, he said that didn't matter to him.

I hesitated, but ended up writing the prescription for 7 Lovaza capsules per day. As soon as I handed to him, I regretted it. In fact, I am embarassed and angry at myself for having given in.

So I vowed: I will NEVER EVER write another prescription for Lovaza.

I do not believe that we should spread the excessive profiteering of the pharmaceutical industry around on the backs of people who pay their healthcare insurance premiums, just so that a few people, like this selfish couple, can save a few dollars a month.

This is your brain on wheat II

In the original Heart Scan Blog post, This is your brain on wheat, I discussed how opioid peptides (i.e., small proteins that act like opiates such as heroine or morphine) that result from digestion of wheat cause unique effects on the human brain, particularly addictive behaviors. I also briefly reviewed how elimination of wheat has been shown to reduce auditory hallucinations and other psychotic behaviors in a subset of people with paranoid schizophrenia.

These two phenomena, addictions and schizophrenia, are most likely the result of exorphins that cross the blood-brain barrier. Exorphins--exogenous morphine-like compounds--can be blocked by opiate-blocking drugs like naloxone and naltrexone. Naloxone is used in hospitals to reverse morphine or heroine overdoses; naltrexone is being repackaged into a weight loss drug, since blocking wheat-derived exorphins reduces appetite. (Yes: The USDA tells us to eat more wheat, the drug industry sells us the antidote.)

There's another way that wheat can affect the brain and nervous system: immune-activated damage.

This is similar to the effect seen in celiac. There's even overlap with some of the antibody markers used to diagnose celiac, like the anti-gliadin antibodies and the anti-endomysium antibodies.

The most common immune neurological syndrome consequent to wheat consumption is cerebellar ataxia, a condition in which an immune response causes damage to the Purkinje cells of the cerebellum, the portion of the brain responsible for balance and coordination. This results in stumbling, incoordination, incontinence, and eventually leads to reliance on a cane or walker and wearing a diaper. Average age of onset: 53 years. A shrunken, atrophied cerebellum can be seen on an MRI of the brain.

Problem: Most people with central nervous system damage caused by wheat do not have any intestinal symptoms, like diarrhea and abdominal pain, the sort of symptoms usually associated with celiac disease. It means the first sign of wheat-induced brain damage may be bumping into walls and wetting your pants.

There's no such thing as a "no-carb" diet

When I tell patients how I advise a wheat-free, cornstarch-free, sugar-free diet on the background of a low-carbohydrate diet, some people ask: "But can I live on a no-carb diet?"

Well, there's no such thing as a "no-carb" diet. Low-carb, yes. No-carb, no.

Here are the carbohydrate contents of various "low-carb" foods:

Gouda cheese--3 oz contains 1.65 grams carbohydrates
Mozzarella cheese--1 cup contains 2.89 grams carbohydrates
Walnuts--4 oz (56 nuts) contains 2.96 grams carbohydrates
Almonds--4 oz contains 1.38 grams carbohydrates
Sour cream--one-half cup contains 3.31 grams carbohydrates
Red wine--3.5 oz glass contains 2.69 grams carbohydrates
Eggplant--1 cup cooked contains 8.33 grams carbohydrates
Green pepper--1 medium-sized raw contains 5.52 grams carbohydrates
Cucumber--1 medium contains 4.34 grams carbohydrates
Tomato--1 medium contains 4.82 grams carbohydrates

(Nutrition data from USDA Nutrient Database)

In other words, foods thought to be "low-carb" actually contain a modest quantity of carbohydrates.

Such modest quantities of carbohydrates may not be enough to trip your blood sugar. But add up all the "low-carb" foods you consume over the course of a day and you can easily achieve 30 grams or more carbohydrates per day even without consuming any higher carbohydrate foods.

Why doesn't your doctor try to CURE diabetes?

Imagine you have breast cancer. You go to your doctor and she says, "As your pain worsens, we'll help you with pain medication. We'll fit you with a special bra to accommodate the tumor as it grows. That's all we're going to do."

"What?" you ask. "You mean just deal with the disease and its complications, but you're not going to help me get rid of it . . . cure it?"

It would be incredibly shocking to receive such advice. Then why is that the sort of advice given when you are diagnosed with diabetes?

Say you go to the doctor. Lab values show a fasting blood sugar of 156 mg/dl, HbA1c (a reflection of your previous 60 days average glucose) of 7.1%. Both values show clear-cut diabetes.

Your doctor advises you to 1) start the drug metformin, then 2) talk to the diabetic teaching nurse or dietitian about an American Diabetes Association (ADA) diet.

The ADA diet prescribed encourages you to increase carbohydrates and cut fats at each meal and maintain a consistent intake so that you don't experience hypoglycemic (low blood sugar) episodes. You follow the diet, which causes you to gain 10-15 lbs per year, increasing your "need" for diabetes medication. You doctor adds Actos, then Januvia, then injections of Byetta.

Three years and 34 lbs later, you are not responding well to the drug combination with blood sugars rarely staying below 200 mg/dl. You've developed protein in your urine ("proteinuria"), lost 30% of your kidney function, and you are starting to lose sensation in your feet. So the doctor replaces some of your medication with several insulin injections per day.

This formula is followed millions of times per year in the U.S. So where along the way did your doctor mention anything about a "cure"?

Adult diabetes is the one chronic disease that nobody cares to cure. Treat it, maintain control over blood sugars, but cure it? Most physicians say it's impossible.

The tragedy is that diabetes is a curable condition. I've seen it happen many times. Physicians dedicated to curing diabetes like low-carb expert, Dr. Mary Vernon, have cured it countless times. Dr. Eric Westman and colleagues have been building the case for the carbohydrate-restricted cure for diabetes with studies such as this. In this last study, of the 8 participants on insulin + medications at the start of the study, 5 no longer required medications at the close of the study--they were essentially non-diabetic.

I tell patients that diabetes, in fact, is a disease you choose to have or not to have--provided you are provided the right diet and tools. Sadly, rarely are diabetics told about the right diet and tools.

That's why Cadbury Schweppes has been a major contributor to the American Diabetes Association, as are other processed food manufacturers and the drug industry, all who stand to profit from maintaining the status quo.

The cure? Eliminate or at least dramatically reduce carbohydrates, the foods that increase blood sugar.

Note: If you have diabetes and you are taking any prescription agents, such as glyburide, glipizide, insulin, and some others, you will need to discuss how to manage your medications if you reduce carbohydrates. The problem is finding a doctor or other resource to help you do this.

LDL pattern B

Here's a Q&A I stumbled on in the Forum of MedHelp, where people obtain answers from presumed health "experts."

Question:

My VAP test results in July 07 identified an LDL Pattern B.
Overall results:
Total 150
HDL 75
LDL 61
Trig 60
HDL-2 17
LP(a) 6.0
LDL Pattern B

Medications:
Lipitor 10mg
Zetia 10mg
Altace 10mg
Atenolol 50mg
Plavix 75mg
Aspirin 81mg

I had several heart attacks which resulted in CABG performed May 2000. I am a 53 year old white male , 6'1", 190 pounds, exercise every day, watch my diet and feel great. Everything looks OK except my LDL Pattern B. Is there any therapy to improve the Patten B?


Answer from CCF, MD:
Your results indicate an LDL pattern B, which generally indicates small atherogenic LDL particles which may cause increased risk for CAD. However, there are several problems with LDL patterning: 1) its unreliability (of LDL pattern testing ), 2) unclear clinical evidence regarding regarding the usefulness of LDL patterns and particle size. The majority of evidence regarding the progression of atherosclerosis is with LDL lowering and to an smaller extent HDL raising.

All available clinical evidence shows that any particles in the VLDL, IDL, or LDL range are atherogenic, and there is no evidence that whether belonging to pattern A or B one is more atherogenic than others.

Subclass studies have proliferated over the last few years, but many of these studies were funded or subsidized either by suppliers of the assays as a method to expand their use and move them into mainstream practice, or by pharmaceutical companies in an attempt to claim some advantage over other therapeutic agents.
Thus, current data on LDL subclasses are at best incomplete and at worst misleading, suffering from publication bias, and now given the recent results of the Ensign et al. study, unreliable.

Your LDL, and HDL are at goal. The Lpa level is still not clearly linked as a modifiable risk factor for CAD, although elevated levels are now know to be linked to stroke.

Continue with your present treatments: aspirin, plavix, ateonol and altace are all essential medications.



Wow. The extent of ignorance that pervades the ranks of my colleagues is frightening.

Contrary to the response, LDL particle size assays are quite reliable and accurate. I've performed many thousands of lipoprotein assays and they yield reproducible and clinically believable results. For example, eliminate wheat, oats, cornstarch, and sugars and small LDL drops from 2400 nmol/L to 893 nmol/L (NMR)--huge drops. If repeated within a short period of time, the second measure will correspond quite closely.

The data are also quite clear: Small LDL particles (i.e., "pattern B") are a potent predictor of cardiovascular events. What we lack are the treatment trials that show that reduction of small LDL results in reduced cardiovascular events. The reason for this is that small LDL research is not well-funded, since there is no prescription drug to treat small LDL, only nutritional means. Niacin (as Niaspan) is as close as it comes for a "drug" to reduce small LDL. But diet is far more effective.

Given the questioner's fairly favorable BMI of 25.1 and his history of aggressive heart disease, it is virtually certain that he has what I call "genetic small LDL," i.e., small LDL that occur on a genetically-determined basis (likely due to variants of the cholesteryl-ester transfer protein, or CETP, or of hepatic lipase and others).

Ignoring this man's small LDL will, without a doubt, consign him to a future of more heart attacks, stents, and bypass. Maybe by that time the data supporting the treatment of small LDL will become available.

What increases blood sugar more than wheat?

Take a look at these glycemic indexes (GI):


White bread 69
Whole wheat bread 72
Sucrose 59
Mars bar 68
White rice 72
Brown rice 66


I've made issue in past of whole wheat's high GI--higher than white bread. Roughly in the same glycemic league as bread are shredded wheat cereal, brown rice, and a Mars candy bar.

With few exceptions, wheat products have among the highest GIs compared to the majority of other foods. For instance:


Kidney beans 29
Chick peas 36
Apple 39
Ice cream 36
Snickers Bar 40


Yes, by the crazy logic of glycemic index, Snickers is a low-glycemic index food.

While I do not believe that low GI makes a food good or desirable, since low GI foods still provoke high blood sugars, small LDL particles, trigger glycation, and other abnormal phenomena, they are clearly less obnoxious than the items in the first list.

Take a look at this list:

Cornflakes 80
Rice cakes 80
Rice Krispies 82
Rice pasta, 92
Instant potatoes 83
Tapioca 81



Starches that are dried and/or pulverized, such as cornstarch, potato starch, rice starch, and tapioca starch (cassava root) will increase blood sugar even more than wheat. Foods with these starches have GI's of 80-100.

Cornstarch, potato starch, rice starch, and tapioca starch: Sound familiar? These are the main starches used in "gluten-free" foods. A hint of the high GI behavior of these dried starches is seen in the GI for cornflakes of 80.

So remember: Wheat-free is not the same as gluten-free. Gluten-free identifies junk carbohydrates masquerading as healthy because they don't contain one unhealthy ingredient, i.e. wheat.

China fiction?

Dr. Colin Campbell caused a stir with publication of his 2005 book, The China Study. Dr. Campbell, after extensive animal and epidemiologic research conducted in China over 20 years, concluded that a diet high in animal protein, especially casein, was associated with increased cancer, osteoporosis, and heart disease risk.

Richard Nikoley of Free the Animal and Stephan Guyenet of Whole Health Source have been talking about an analysis of the China Study raw data performed by a young woman named Denise Minger.

Denise's analysis is nothing short of brilliant, absolutely "must" reading for anyone interested in nutrition.

Her comments on the relationship of wheat to heart disease:

Why does Campbell indict animal foods in cardiovascular disease (correlation of +1 for animal protein and -11 for fish protein), yet fail to mention that wheat flour has a correlation of +67 with heart attacks and coronary heart disease, and plant protein correlates at +25 with these conditions?

Speaking of wheat, why doesn’t Campbell also note the astronomical correlations wheat flour has with various diseases: +46 with cervix cancer, +54 with hypertensive heart disease, +47 with stroke, +41 with diseases of the blood and blood-forming organs, and the aforementioned +67 with myocardial infarction and coronary heart disease?

Carbohydrate-LDL double whammy

Carbohydrates in the diet trigger formation of small LDL particles. Because carbohydrates, such as products made from wheat, increase triglycerides and triglyceride-containing lipoproteins (chylomicrons, chylomicron remnants, VLDL, and IDL), LDL particles (NOT LDL cholesterol) become triglyceride-enriched. Triglyceride-enriched LDL particles are "remodeled" by the enzyme, hepatic lipase, into triglyceride-depleted, small LDL particles.

The list of reasons why small LDL particles are more atherogenic, i.e., plaque-causing, is long:

--Small LDL particles, being smaller, more readily penetrate the endothelial barrier of the arterial wall.
--Small LDL particles are more adherent to glycosaminoglycans in the artery wall.
--Small LDL particles are poorly taken up by the liver LDL receptor, but enthusiastically taken up by macrophage receptors of the sort in your artery walls.
--Because of their poor liver clearance, small LDL persists in the bloodstream far longer than large LDL.
--Small LDL particles are more oxidation-prone. Oxidized LDL are more likely to trigger inflammatory phenomena and be taken up by macrophages in the artery wall.

Let me add another reason why small LDL particles are more likely to cause plaque: They are more likely to undergo glycation. (More on glycation here.)

Glycation occurs when glucose (sugar) molecules in the blood or tissue modify proteins, usually irreversibly. Small LDL particles are uniquely glycation-prone. (This is likely due to a conformational change of the apoprotein B in the small LDL particle, exposing lysine residues along apo B that become glycated.)

Here's a great demonstration of this phenomenon by Younis et al:


"LDL3" is the small type. Note that small LDL particles are 4-5 times more glycated than large LDL. That's a big difference.

Once glycated, small LDL is especially resistant to being taken up by the liver. Like annoying in-laws, they hang around and hang around and . . . The longer they hang around, they more opportunity they have to contribute to plaque formation.

So, carbohydrates trigger formation of small LDL particles. Once formed, small LDL particles are glycated when blood sugar increases. While LDL can be glycated even when blood sugars are in the normal range (90 mg/dl or less), glycation goes berserk when blood sugars go higher, such as a blood sugar of 155 mg/dl after a bowl of steel-cut oatmeal.

To lose weight, prick your finger

We know that foods that trigger insulin lead to fat storage. Putting a stop to this process allows you to mobilize fat and lose weight. If you're starting out from scratch, rapid and dramatic weight loss can be experienced, as much as one pound per day.

So how can you stop triggering insulin?

The easiest way is to eliminate, or at least minimize, carbohydrates. My favorite method to restrict carbohydrates is to eliminate wheat and minimize exposure to other carbohydrates, such as oats, cornstarch, and sugars. All these foods, wheat products worst of all, cause blood sugar and insulin to skyrocket.

Another way is to check your blood sugar one hour after completing a meal and keep your after-eating, or "postprandial," blood sugar 100 mg/dl or less. Let's say you are going to eat stone ground oatmeal, for example. Blood sugar prior to eating is, say, 90 mg/dl. One hour after oatmeal it's 168 mg/dl--you know that this is going to trigger insulin and make you fat. Oatmeal should therefore be eliminated.

Keeping blood sugar to 100 mg/dl or less after eating teaches you how to avoid provocation of insulin. A shrinking tummy will follow.

To do this, you will need:

1) A glucose meter--My favorite is the One Touch Ultra Mini ($13.42 at Walmart). It's exceptionally easy to use and requires just a dot of blood. Drawback: Test strips are about $1 each. Accuchek Aviva is another good device. (We've had a lot of problems with Walgreen's brand device.)
2) Test strips--This is the costly part of the proposition. Purchased 25 or 50 at a time, they can cost from $0.50 to $1.00 a piece.
3) Lancets--These are the pins for the fingerstick device that comes with the glucose meter. A box should be just a few dollars.

No prescription is necessary, nor will insurance pay for your costs unless you're diabetic. To conserve test strips, use them only when a new, untested food or food combination is going to be consumed. If you had two scrambled eggs with green peppers, sundried tomatoes, and olive oil yesterday and had a one hour postprandial glucose of 97 mg/dl, no need to check blood sugar again if you are having the same meal again today.

Iodine update

As the iodine experience grows, I've made several unique observations.

Up to several times per day, I see people who are responding in some positive way to iodine supplementation. (See previous Heart Scan Blog posts about iodine: Iodine deficiency is REAL and The healthiest people are the most iodine deficient.)

Among the phenomena I've observed:

1) A free T4 thyroid hormone at the low end of normal, or even in the below normal range, along with a highish TSH (usually >1.5 mIU/L) are the most frequent patterns that signal iodine deficiency. Occasionally, a low free T3 value will also increase, though this is the least frequent development.

2) At a dose of 500 to 1000 mcg iodine per day, it requires anywhere from 3 to 6 months to obtain normalization of thyroid measures.

3) Reversal of small goiters also occurs over about 6 months.

4) Iodine intolerance is uncommon. If it occurs, using a low starting dose, e.g., 100-200 mcg per day, usually works. The dose can be increased gradually over the ensuing months.

5) Perceptible benefits of iodine occur only occasionally. The most common perceptible effects are increased energy and increased warmth, especially of the hands and feet.

6) Some people who have taken thyroid hormones for years will develop reduced need for their medication with iodine supplementation. In other words, their physician was inadvertently treating iodine deficiency with thyroid hormone replacement. Anyone already on any thyroid preparation(s), e.g., Synthroid, levothyroxine, Armour thyroid, Naturethroid, etc., should watch for signs of hyperthyroidism when iodine is added. But having your own thyroid gland make its own thyroid hormones is better and healthier than relying on the prescription agents. Just be sure to monitor your thyroid measures.

7) Iodine toxicity can occur--Two people in my clinic population developed iodine toxicity by taking 6000 mcg iodine per day for 6 or more months. (Both patients did it on their own based on something they read). Iodine toxicity is evidenced by shutting down your thyroid, i.e., marked increase in TSH, e.g., 15 mIU/L.


Most of the people in my clinic obtain their iodine from kelp tablets. Some use potassium iodine (KI) drops. A handful have used the high-potency Iodoral (12.5 mg or 12,500 mcg iodine per tablet); this was also the form that generated the toxic effects in the two females.

All in all, iodine deficiency is actually far more common than I ever suspected. Not everybody is iodine deficient. But a substantial minority of the Midwest population I see certainly are.
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.

    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,

    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?

    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.

    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.
