No flush = No effect



"Inositol Hexanicotinate is the true 'flushless niacin.' Unlike 'sustained-release' niacin, which is just regular niacin in a pill which dissolves more slowly, Inositol Hexanicotinate is a niacin complex, formed with the B-vitamin-like inositol. When you take an IHN supplement, the central inositol ring gradually releases niacin molecules, one at a time delivering true niacin. This, like “sustained-release” niacin, allows you to take niacin at clinically-proven doses without going crazy with the itch."


That above bit of nonsense adorns one manufacturers sales pitch for its no-flush niacin. No-flush niacin is one of the biggest scams in the health food store.

Ordinarily, I love health food stores. There's lots of fun and interesting things available that pack real power for your health program. Unfortunately, there's also outright nonsense. No-flush niacin is absolute nonsennse.

No-flush niacin is inositol hexaniacinate, or an inositol molecule complexed with 6 niacin molecules. So it really does contain niacin. However, although it works in rats, it exerts no known effect in humans.

Just Friday, a 41-year old woman came to my office for consultation because her doctor didn't know what to do with lipoprotein(a). She had seen a cardiologist who told her to take no-flush niacin. Both the cardiologist and the patient were therefore puzzled when lipoprotein(a) showed no drop and, in fact, was slightly higher on the no-flush preparation.

The lack of any observable effect and no studies whatsoever showing a positive effect (there is one study demonstrating no effect), manufacturers continue to manufacture it and health food stores continue to push it as an alternative to niacin that causes the flush. It's quite expensive, commonly costing $30-$50 for 100 tablets.

Don't fall for this gimmick. Niacin is among the most helpful of treatments for gaining control over coronary plaque. It raises HDL, corrects small LDL, reduces triglycerides (along with its friend, fish oil, of course), reduces lipoprotein(a), and dramatically contributes to reduced heart attack risk. No-flush niacin does none of this.

"Black holes" on heart scan


Lots of smokers, especially younger smokers, rationalize their habit by telling themselves that they'll stop if and when any hint of adverse health effects develop.

The problem is that, even in the first decade of smoking, dramatic and profound effects can develop--but you won't know it.

One of the most graphic examples of this I see every day in people who have heart scans. While CT heart scans are, of course, for identification of coronary plaque/coronary disease, they're also great for visualizing the lungs.

This man is a light smoker. The lungs are the black tissues (that's normal) on either side of the (white) heart in the center. Now, note the holes in the lung tissue. That's what they literally are: holes left by the destrucive, tissue-eating effects of cigarette smoking.

How common are the holes (or emphysematous "blebs", as they're called in medical lingo)? Very common. You'll even see them in 30-somethings who've smoked only a few years.

These are holes that have nothing in them. The lung tissue that was destroyed to create the hole will never grow back, even when smoking stops. The holes in this example are actually small to average in size. I've seen much bigger. And this only represents the early stages of lung tissue destruction. A long-time heavy smoker shows all other sorts of abnormalities.

Whenever I show these "black holes" to people who smoke, they are horrified and I've actually gotten many people to quit. Take the opportunity to quit as soon as you can if you smoke.

Small LDL--a persistent bugger

Sometimes, small LDL is easy to get rid of. Take niacin, for instance, and it can simply disappear from your body.

But other times, it can be aggravatingly persistent. Several times every day, in fact, I need to run through the checklist of strategies to reduce small LDL with patients.

How important is small LDL? In my experience, it is among the most potent causes behind coronary plaque known. It's a big part of the explanation why some people at an LDL of cholesterol of X mg/dl will have heart disease, while others with the same X mg/dl of LDL will not. When present, small LDL particles are much more likely to trigger atherosclerotic plaque formation. Small LDL particles magnify Lp(a)'s ill-effects tremendously. The data vary but small LDL probably increases heart attack risk at least three-fold.



Here's a checklist of strategies that I advise patients to consider to minimize the small LDL pattern:


--Lose weight to ideal weight--This is very important and effective.


--Fish oil--A relatively small effect unless triglycerides are high to begin with.




--Reduction of wheat products--This can provide a BIG effect. More precisely, a reduction in high-glycemic index foods is effective. But the biggest day-to-day high-glycemic food culprits are wheat products like breads, pasta, crackers, chips, pretzels, and breakfast cereals. "You mean whole wheat bread makes small LDL?!" Yup.


--Reduction of sweets--For the same reasons as reducing wheat products.


--Add raw almonds and walnuts--1/4 to 1/2 cup per day.




--Replace wheat products with OAT products, especially oat bran. This does NOT mean oat-containing breakfast cereals with added sugar and wheat, e.g., Honey Nut Cheerios, Cracklin' Oat Bran Cereal, etc. You might as well eat candy. Buy oat bran as plain oat bran--nothing added. Use it as a hot cereal or added to yogurt, "breading" for chicken, etc.




--Vitamin D--A variable effect, likely resulting from its beneficial effects on "insulin resistance".


--Exercise


--Niacin--Very effective but not always enough.


Among the choices, my favorites are weight loss, niacin, and reduction of wheat products. Those will give you the biggest bang for your buck.

Red badge of courage

A group of 60- and 70-somethings were standing in the anteroom to the cardiac rehabilitation center. All (males) had their T-shirts pulled up, comparing their coronary bypass scars.

It reminds me of war veterans comparing their war wounds. The scars of suffering, of having "conquered" and won a war with a common enemy, a badge of courage.

This is part of the broad social acceptance of bypass surgery and other major procedures for heart disease. Hospitals support it. They do it for the psychological support for patients enduring a difficult process. Often, talking about a shared experience can be a helpful purge for the fears and frustrations of a traumatic event.

Curious thing, though. I've actually had people request bypass surgery simply because all their friends have had one. No kidding. "I just figure my time is coming. I might as well get it over with."

Get the picture? We've had a battle with heart disease and the hospitals have won. The enormous success of hospitals over the last 20 years is not because of delivering babies, it's not from psychiatric hospitalization, it's not from cancer treatment. It's from heart disease. The largest floors in the hospital are usually the cardiac floors. The bulk of revenues and profit are from heart disease.

If I manufacture widgets and each widget I sell makes me scads of money, guess what? I want to sell more and more widgets. I'll persuade people they need my widgets even if they don't. Perhaps I'll even persuade them that buying one is a noble cause. Maybe I'll subtly suggest that I am a charitable operation and I only sell my products for the public good. I could even name my company after a saint. Personal profit--absolutely not!

Ignore the hype. See hospitals and their "products" for what they are: A necessary service--some of the time; profitable products that they hope to sell to more and more people most of the time.

"We don't believe in heart scans"

Tim's CT heart scan score was an earth-shattering 3,447, clearly in the upper stratosphere of percentile rank. Risk of heart attack: 25% per year. At age 58, it was a wonder that nothing had happened yet.

Tim went to the Cleveland Clinic for an opinion, long a powerful bastion of heart procedures. The consulting cardiologist told Tim, "We don't believe in heart scans. They're wrong too often."

An opinion from a widely-respected cardiovascular center. If they don't "believe" in heart scans, does that mean they "believe" in stents and bypass surgery? Does it mean that the thousands of research studies that have now been published on the value of heart scanning are pure fiction? Is there a choice to believe or not believe?

I continue to be shocked at the extraordinary ignorance on the topic of heart scanning among my colleagues. The number one killer of Americans and you still rely on stress tests?

Why this perception that heart scans are "wrong too often"? What this cardiologist means, I believe, is that when people are taken to the cath lab for catheterization, a substantial number of those with positive heart scan scores don't have "blockage". But I could have told him that even before the heart catheterization.

There is an expected and well-documented likelihood of finding significant "blockage" based on your heart scan score. At Tim's scary score of 3,447, what is the likelihood of "blockage" of 50% or more? It's around 40-50%. That means that half the people at this score will have a blockage sufficient to justify inserting stents or undergoing bypass surgery, half will not. There will indeed be many plaques, but none severe enough to block flow.

Does that make the heart scan wrong? I don't think it does. Just because you don't need a major procedure to "fix" blockages does not mean that no heart disease is present. Without preventive efforts, Tim's heart attack risk remains an alarming 25% per year--whether or not he gets stents or bypass. The only treatments that substantially reduce this risk (in an asymptomatic person) are preventive efforts, not procedures.

Yet cardiologists like the one Tim consulted at the Cleveland Clinic regard heart scans as something "he doesn't believe in". I would suggest a return to the textbooks and published literature and re-thinking how heart disease should be managed.

Heart scans should provide an opportunity for prevention, not an opportunity for profit.

More on the “Rule of 60”

Despite its apparent simplicity, there’s a lot of thought and wisdom in the Rule of 60.

What if you achieve only a single value in the Track Your Plaque “Rule of 60”? What if, for instance, you got LDL down to 60 mg/dl, but ignored the fact that your HDL was 41 mg/dl and triglycerides were up to 145 mg/dl? Can you still do pretty well?

Probably not. In fact, this specific combination of low HDL and high triglycerides tells me several things:

1) LDL is really much higher than suggested by the 60 mg/dl, which is a calculated value, often much higher. Recall that calculated LDL is prone to immense inaccuracy. When measured, the LDL is commonly somewhere between 120 and 160 mg/dl. However, when you raise HDL to 60 and reduce triglycerides to 60, much of the inaccuracy is removed, i.e., calculated LDL becomes more accurate. LDL can be measured as LDL particle number (NMR), apoprotein B, or direct LDL.

2) LDL particles are small. This is yet another reason why the weight-based LDL measures can be inaccurate. Imagine you have two identical glass jars full of marbles. One jar has small marbles, the other has large marbles, but both jars have the same weight in marbles. Which jar has more marbles? The one with small marbles, of course. The same phenomenon occurs with LDL particles: at the same weight, you can have different numbers of LDL particles. It’s the number of particles that better determine risk for heart disease, not the weight.

3) Triglycerides of 145 mg/dl is actually below the target advised by the National Cholesterol Education Panel Adult Treatment Panel-III guidelines, i.e., you’re okay by conventional standard. But look beneath the surface, and you’ll find that triglycerides at 145 mg/dl are associated with flagrant excesses of VLDL lipoprotein particles and a greater likelihood of a postprandial (after-eating) disorder (increased IDL or postprandial triglycerides), both of which add to coronary plaque.

4) This pattern is also commonly associated with higher blood sugar, higher blood pressure, increased inflammation (e.g., C-reactive protein), increased fibrinogen—all the facets of the metabolic syndrome, or pre-diabetes.

In fact, some of the most aggressive plaque growth—increasing heart scan scores—will occur with this specific pattern. So just achieving one facet of the Track Your Plaque Rule of 60 does not suffice. It’s the whole package that really stacks the odds in your favor of stopping or dropping your heart scan score.

The Track Your Plaque “Rule of 60”

The Track Your Plaque recommended targets for conventional lipids (i.e., LDL, HDL, triglycerides) are LDL 60 mg/dl, HDL 60 mg/dl, and triglycerides 60 mg/dl: 60-60-60.

Not only is this set of values easy to remember—60-60-60—but is grounded in science and the results of clinical trials.

LDL 60 mg/dl
The LDL target is based on experiences such as that of the Reversal Trial, the PROVE-IT Trial, and the Asteroid Trial, all of which showed that LDL cholesterol values in the range of 60 mg/dl dramatically enhance the likelihood of stopping plaque growth or achieving regression, reducing risk of heart attack more than more lenient LDL targets.


HDL 60 mg/dl
Achieving HDL cholesterol of 60 mg/dl is not as well grounded as LDL targets, mostly because increasing HDL is more difficult. There’s also no tremendously profitable way to raise HDL, as there is for reducing LDL (statin drugs). But epidemiologic observations strongly suggest that HDL of 60 mg/dl provides maximum control over both coronary plaque growth, as well as slashing rates of heart attack. Numerous smaller trials have borne this phenomenon out.


Triglycerides 60 mg/dl
Triglycerides of 60 mg/dl is based principally on studies that have shown a virtual elimination of abnormal lipoproteins, especially small LDL, when this value is achieved. Reduction of triglycerides is an effective means to reduce hidden lipoproteins like small LDL and VLDL. Triglycerides in the conventionally acceptable range of 100-150 mg/dl can be associated with dramatic abnormalities of lipoproteins.


Thus, the Track Your Plaque “Rule of 60”. In our day to day experience of trying to stamp out plaque growth from its terrifyingly rapid 30% per year, or reversing it—-dropping your heart scan score—-the Rule of 60 has held up time and again. Getting your lipids to 60 mg/dl does not guarantee that plaque growth stops, but it appears to be a necessary requirement that tips the scales heavily in your favor.

Those of you who’ve discussed lipid targets with your doctor will quickly recognize that the Track Your Plaque targets appear laughably ambitious, perhaps unnecessary. Recall that your doctor likely has no idea of what coronary plaque regression means. He/she likely conforms to the lax targets set by the National Cholesterol Education Panel (NCEP). (These targets depend on a number of factors such as whether you’re diabetic, sex, risk factors, etc.) Based on trial experiences like the few mentioned above, as well as my experience with purposeful coronary plaque reversal, the lipid guidelines as advocated by NCEP guarantee heart disease. Let me emphasize that again: Follow the guidelines set by the NCEP for your doctor to follow, and progression of heart disease is a virtual certainty. At best, it may slow growth of plaque and delay your heart attack or bypass surgery, but it will not stop it.

Now, that point made, let me make another: Just knowing about the targets and even becoming a member of the Track Your Plaque program does not mean that your lipids with automatically go to 60-60-60. We’ve actually had an occasional person tell us that they were disappointed that, by becoming Members, why hadn’t their lipids gone to 60-60-60?

Knowing that the 60-60-60 targets provide real advantage is not the same as actually achieving them.

A little bit of fish oil


The British National Health Service (NHS) has announced that, in light of the substantial data documenting that omega-3 fatty acid intake from fish reduces likelihood of cardiovascular events by around 40%, that Brits discharged from hospital following a heart attack should be "prescribed" 1000 mg of prescription fish oil per day.

Hardly a revolutionary concept. Part of the timidity of the British NHS seems to relate to the potential cost to the government, since apparently much of the cost will be borne by the government-subsidized health system.

But prescription fish oil? Why prescription fish oil? Prescription Omacor, one capsule per day, costs around $70 (U.S.) per month. If I go to Sam's Club the same quantity of omega-3 fatty acids (in three capsules) will cost around $2.50. That's less than 5% of the cost of the prescription form.

Omacor is clearly more concentrated. But is the prescription form better--more effective, more purified, less contaminated, etc.? I have seen no independent verification of this. Of course, manufacturers make all sorts of claims. The only independent, unbiased testing I'm aware of comes from organizations like Consumer Reports and www.consumerlabs.com. Omacor has not been compared to non-prescription fish oil in any of their analyses. Head-to-head comparison of Omacor to nutritional supplement fish oil is unlikely to come from Solvay, the manufacturer of Omacor. Drug companies powerfully resist head-to-head comparisons, fearing it will not play out in their favor. Let the public remain ignorant and hope marketing conquers all.

Why would the NHS only recommend eating fish and prescription fish oil? I don't know, but it smells awfully fishy to me. As soon as an opportunity for profit is built into a treatment, all of a sudden it gains endorsement. Perhaps lobbying by those parties with potential for profit drove the process.

Nonetheless, despite the filthy politics and under-the-table dealings, some good comes out of the NHS's action: broader recognition of the power of fish oil. Perhaps when a British patient or an American patient gets discharged with a prescription for Omacor, the patient will take the initiative and go to the health food store instead and save him (or his insurer) $67.50 per month.

For your coronary plaque control program and control and/or reversal of your heart scan score, we start at 4000 mg per day of standard fish oil, providing 1200 mg per day of omega-3 oils. This amount as a nutritional supplement costs only a few dollars a month. And you have the satisfaction of not only taking a powerful step for your health, but also not enriching the overflowing pockets of drug companies.

AHA: Doctors don't have time for prevention

Doctors "don't have enough time to educate their patients and to stop and think about what measures the patient really needs," says Dr. Raymond Gibbons, new head of the American Heart Association.

Dr. Gibbons highlighted how the system reimburses generously for performing procedures, but reimburses relatively little (often just a few dollars) for providing preventive counseling. He claims to have several ideas for solutions.

Good for Dr. Gibbons. There's no doubt that the lack of truly effective preventive information and counseling is a systemic, built-in flaw in the current medical environment. It is especially true in heart disease.

Another problem: "If a doctor didn't say it, it must not be true." That's the attitude of many of my colleagues. Despite their broad and systematic failure to provide preventive counseling, most physicians (my colleagues the cardiologists especially) pooh-pooh information that comes from other sources. Yet, it's my prediction that much of healthcare will go the way of optometry--direct access to care, often delivered in non-healthcare settings like a store or mall. People are hungry for truly self-empowering health information. Too many physicians can't or won't provide it. You've got to turn elsewhere for it.

That's one of the main reasons I set up the Track Your Plaque program. It's direct access to self-empowering information. A flaw: You still require the assistance of a physician to obtain lab values, lipoproteins, and to monitor certain treatments (e.g., niacin at higher doses). If I knew of a way around this, I'd tell you. But right now I don't. We remain constrained by legal and moral obligations.

Nonetheless, phenomena like CT heart scanning and the Track Your Plaque program are just a taste of things to come.

Confusion about Lp(a)

Since the recent reader question about Lp(a), I've had several other instances of confusion over Lp(a).

To help you navigate through some of the often confusing issues behind this complex genetic abnormality, here are some common sense rules to follow. When you ask your doctor to draw a Lp(a), try to be certain that:

--the same laboratory is always used. Just going from lab to lab can account for huge variation in Lp(a). As standardization proceeds internationally, this will be become less important. But in 2006, it's still an issue.

--you and your doctor resist the temptation to check Lp(a) frequently. I saw a patient recently who was having Lp(a) levels nearly every month. This is pointless. Lp(a) changes very slowly. Checking it frequently will not allow any treatment to be fully reflected. All you'll observe is random variation that can be frustrating. We wait at least 6 months before re-checking after a new treatment is introduced.

If you have a choice, I would recommend you opt for the measure provided by Liposcience (NMR). The technique they use is a particle count measure, rather than a weight-based measure. This may be more accurate, particularly when Lp(a) is small.

Lp(a) remains among the more difficult patterns to understand and correct. Don't be surprised if you encounter a lot of confusion from your doctor, as well. You may end up providing much of his/her education.
Bet you can't fast

Bet you can't fast

People who continue to consume the world's most destructive grain, i.e., wheat, can rarely endure fasting--not eating for an extended period--except by mustering up monumental willpower. That's because wheat is a powerful appetite stimulant through its 2-hour cycle of exaggerated glycemia followed by a glucose low, along with its addictive exorphin effect. Wheat elimination is therefore an important first step towards allowing you to consider fasting.

Why fast? I regard fasting as among the most underappreciated and underutilized strategies for health.

In its purest form, fasting means eating nothing while maintaining hydration with water alone. (Inadequate hydration is the most common reason for failing, often experienced as nausea or lightheadedness.) You can fast for as briefly as 15 hours or as long as several weeks (though I tell people that any more than 5 days and supervision is required, as electrolyte distortions like dangerously low magnesium levels can develop).

Among its many physiological benefits, fasting can:

  • Reduce blood pressure. The blood pressure reducing effect can be so substantial that I usually have people hold some blood pressure medications, especially ACE inhibitors and ARB agents, during the fast since blood pressure will drop to normal even without the drugs. (A fascinating phenomenon all by itself.)

  • Reduce visceral fat, i.e., the fat that releases inflammatory mediators and generates resistance to insulin.

  • Reduce inflammatory measures

  • Reduce liver output of VLDL that cascades into reduced small LDL, improved HDL "architecture," and improved insulin responsiveness. (The opposite of fasting is "grazing," the ridiculous strategy advocated by many dietitians to control weight. Grazing, or eating small meals every two hours, is incredibly destructive for the opposite reason: flagrant provocation of VLDL production.)

  • Accelerate weight loss. One pound per day is typical.


Beyond this, fasting also achieves unique subjective benefits, including reduced appetite upon resumption of eating. You will find that as single boiled egg or a few slices of cucumber, for example, rapidly generate a feeling of fullness and satisfaction. Most people also experience greater appreciation of food--the sensory experience of eating is heightened and your sense of texture, flavors, sweetness, sourness, etc. are magnified.

After decades of the sense-deadening effects of processed foods--over-sugared, over-salted, reheated, dehydrated then just-add-water foods--fasting reawakens your appreciation for simple, real food. On breaking one of my fasts, I had a slice of green pepper. Despite its simplicity, it was a veritable feast of flavors and textures. Just a few more bites and I was full and satisfied.

Once you've fasted, I believe that you will see why it is often practiced as part of religious ritual. It has an almost spiritual effect.

More on fasting to come . . .

    1. Should I continue to take all my supplements and medications during fasting, e.g. Niacin, or does it depend?
    2. If upon fasting, satiety comes after eating a small amount of food, how do I make sure my nutrition is sufficient to maintain the muscle mass? How do you combine fasting and exercise?

  • Joe

    5/26/2011 4:52:26 PM |

    Gene, my guess is that you can't. Or shouldn't. But then you're probably not going to fast for more than a few days at most, so going without exercise for a few days is probably not going to cost you any muscle mass.

    I would also think it's probably okay to take your usual supplements, too.  Medicines may be a problem, depending on what they are.  People with serious health issues probably should avoid fasting altogether, unless under the close supervision of his or her doctor.

    I'm interested in hearing what Dr. Davis has to say regarding fasting.  Hurry up doc!

    I've had a similar experience to your post-fast feeling upon eating by doing a 2 or 3 day liquid-only diet that's heavy on water and includes a large protein shake each day.  It's as though you have to periodically remind the part of your brain that listens to the stomach what "full" means.

    Like the others, I'm very interested in what the doc has to say in the next article in this series!

    Type 1 diabetic for 40 years, and nowadays I eat about a thousand-calorie high-fat breakfast and a similar dinner.  I rarely eat lunch, and skipping breakfast (simply omit the pre-meal shot of insulin) as well is usually not a big deal any more: I do it occasionally.  Control of blood sugar is much easier now, and Hb A1c around 6 rather than over 10: still room for improvement.  When I was eating skimmed milk with Grape-Nuts or Uncle Sam (whole wheat flakes with whole flaxseed) for breakfast I would have blood sugars as high as 300 by mid-morning and a powerful hunger by lunchtime.  Whatever benefits fasting may have, I find it a lot easier now than it once was, and plan to try it more often, as I'm still overweight.

    I experimented with intermittent fasting (IF) for a little over a year. I first got interested in IF through calorie restriction (CR) -- there were a couple papers suggesting that you could extend lifespan through IF without the CR, which seemed like the perfect combination.

    These papers are still quoted on many blogs, but I doubt many have actually read them, since none of them actually show you can increase lifespan without restricting calories. See this post for a more detailed analysis:

    http://inhumanexperiment.blogspot.com/2010/05/does-intermittent-fasting-increase.html

    Anyhow, I still think there might be benefits for doing intermittent fasting -- though I've also seen some studies showing it might have negative effects as well -- and certainly it seems pretty good for weight loss. When I was on a high-fat, low-carb diet and fasting for 24 hours, then eating for 24 hours, I was the leanest I'd ever been. And that was without trying or counting calories:

    http://inhumanexperiment.blogspot.com/2009/08/year-of-intermittent-fasting-adf.html

    Hi, Gene--

    Green vegetables have no discernible postprandial chylomicron/VLDL consequence and is the exception. I'd consider that safe "grazing."

    We usually hold niacin during a fast due to the fluid struggles, which can magnify the hot "flush." We usually continue the other supplements, however.

  • Dr. William Davis

    5/27/2011 11:41:49 AM |

    Hi, Paul--

    If not yet corrected, I don't think it would be a good time to fast, since you could feel pretty crumby during your fast.

    Fasting should be a positive experience, not something to endure. I'd wait until these issues are corrected.

  • Dr. William Davis

    5/27/2011 11:45:56 AM |

    Hi, JLL--

    Agreed. In fact, I believe that the greatest benefits of intermittent fasting are the subjective benefits of reawakened taste and appreciation of food, rather than the physiologic benefits. Nonetheless, it makes sense that, since atherosclerosis and arterial dysfunction are to a large degree postprandial phenomena, prolonged "no-prandial" periods might facilitate arterial health.

    I have been following Fast-5 for three years, and quickly got down to a healthy weight. I'm 58 years old and lost 25 lbs to get down to 160lb (5'-11''), and a reasonable BMI. I fast daily for 19 to 21 hours with absolutely no effort required - it is just the way I live now. During this whole time I have made no effort to restrict wheat in any way. I don't eat a lot of wheat and I don't eat it every day, but on the day after pigging out on pizza I have no trouble with my fasting. There's your black swan.

    Ketone metabolites from Beta oxidation of fatty acid, B-hydroxy-butyrate , increase when fasting;  these metabolites act on visceral fat receptor HM74A. The result is upregulation of the anti-inflammatory  molecule adiponectin;  it (adiponectin)  also keeps less glycerols  (think of tri-glyceride group).

    The increased adiponectin upshot is the white visceral adipose (not subcutaneous fat) does less lypo-lysis (fat cleaving) and there is a reduced level of free fatty acids going into circulation.  This relief, from excessive "freed" fatty acids ,  permits the response to insulin to improve (ie: sensitivity to insulin better) when go back to eating;  and the longer the fast went on for  the longer the boost of circulating adipinectins stays  around   than before.

    Low serum adiponectin levels are common in the obese, hyper-glycaemic,  diabetic;  individuals with  hyper-triglycerides, coronary artery disease (and often even the children of  hyper-tensives.  Metabolic syndrome tends to low adiponectin and concurrent high levesls of circulating triglycerides.

    The  actual anti-inflammatory action of adiponectin is a major  part of why the fast makes the body feel so much better;  the digestive  organ rest is given too much focus.   Many individuals report  " pain gone"  from diets  that favor more ketone derived energy
    production (like low carb,  calorie restriction &/or  ferments for gut bacteria) ;  because,  there too, the metabolite Beta hydroxy-butyrate is instigating more circulating adiponectin that  then stymies pro-inflammatory cytokines.

    Hi, Might--

    You make a crucial point that, I believe, explains much of the benefits to fasting: via improvements in cytokine levels and tissue responsiveness, especially adiponectin.

    Fabulous!

    Hi, Curtis--

    Exactly. There are going to be exceptions. However, I speak for the 80% or more people who do indeed have addictive and appetite-increasing relationships with wheat.

    I wasn't able to fast when Dr. Davis started discussing it about 1-2 years ago. Most of my life, if I didn't "graze", I'd get hypoglycemic symptoms like my mother, and my paternal grandmother. My mother even got a note from my doctor that I had to have a sandwich before Jr high band practice, else I'd get headaches or light-headed - that's how long I've dealt with frequent hypoglycemia episodes.

    So I came up with my own personal mini-fast-challenge. I would only eat when an actual hypoglycemic symptom happened, ignoring the regular hunger pangs. Then when I ate, I avoided sugars, starch and wheat - I did have a bit of rice though. I'm guessing it was about 3-4 days before I could go 5-6 hours with no hypoglycemic symptoms, and about 10'ish days before I could go 12 waking hours with no calories (I draink tea with stevia).

    Looking back, both my parents' families ate lots of wheat: bread, biscuits, pasta, so that's probably what gave my paternal grandmother, mother, and then me our hypoglycemia. If I have a hypoglycemic symptom, I start my mini-fast-challenge again. I finally figured out my family's curse is wheat, so I avoid it except the occasional pasta dish.

    I followed the "East Stop Eat" approach a while back, with good results. I agree with one poster that said best to skip the breakfast insulin surge. In fact I think the whole "three square meals" with grazing in between, needs to be challenged (perhaps one meal a day). My guess is that humans are designed to go days without food and have plenty of energy. Its an ability that needs to be regained. Also I gather fasting is good for HGH response, especially if combined with resistance training.

    Dr. Davis, I have done intermittent fasting for a long time...so long, I have lost count but I think that it has been 4 years. I do my version on a daily basis so it I am not as strict as someone who does this occasionally. Now that being said, my final meal of the day is the meal that I begin my fast so I keep it as nutritious and ketogenic as possible. So, I eat my final meal at around 7:00 P.M. I don't eat again until 3:00 P.M. the following day. Eating is such a treat and I eat very tasty low carb food when I break my fast. I will have my morning coffee with heavy whipping cream and MCT oil. Or I will have a glass of water with MCT oil. I take my vitamin D at this time of day because it wards off any allergy bugs lurking in the air. This summer I would like to lose 10 lbs so I will just kick up my fasting method in intensify my diet by keeping it balanced between protein and fats.

    I am not athletic in the least but I find that being active is not hindered during fasting. I strongly believe that we should not need to eat before exercise. Nor should we need to eat immediately after exercise.

    Sorry, I just noticed that post came up under my husband's name. That post on fasting should come up under my name Mary...I am the one playing flute.

    Yes, I do agree with you . I read about HGH becoming activated through a combination of fasting and resistance training.

    18 hour fasts are easy, 24 hour fasts are hard, but once I break the 24 hour barrier, another 12-16 hours isn't bad.  My diet isn't wheat heavy, but I certainly don't avoid it.  What works for me is moderate physical activity, which gets me over the hump.  The hump may be the switchover from carb burning to fat burning, which moderate activity of a couple hours duration trains the body to do.

    Dr. Davis,
    Please refer me to your source of  "wheat is destructive".  I have eaten Shredded Wheat breakfast cereal every day for 25 years.  It is the only breakfast cereal I am not allergic/sensitive to.  After eating it for breakfast, it fills me up and I do not eat again for 6 hours.  I understand about wheat products raising a person's glycemic index, but I have read that the fiber in Shredded Wheat takes so long to digest that it actually controls a person's blood sugar all day.
    I am a healthy, near ideal-weight 50 year-old female.  My experience finds this statement to be false: "wheat is a powerful appetite stimulant through its 2-hour cycle of exaggerated glycemia followed by a glucose low, along with its addictive exorphin effect".
    Thank you for your time.
