The Paleo approach to meal frequency

24. November 2009 William Davis (12)
Furthering our discussion of postprandial (after-eating) phenomenona, including chylomicron and triglyceride "stacking" (Grazing is for cattle and Triglyceride and chylomicron stacking), here's a comment from the recent Palet Diet Newsletter on the closely related issue, meal timing and frequency:


We are currently in the process of compiling meal times and patterns in the worlds historically studied hunter-gatherers. If any single picture is beginning to emerge, it clearly is not three meals per day plus snacking ala the typical U.S. grazing pattern. Here are a few examples:

--The Ingalik Hunter Gatherers of Interior Alaska: 'As has been made clear, the principal meal and sometimes the only one of the day is eaten in the evening.'
--The Guayaki (Ache) Hunter Gatherers of Paraguay: 'It seems, however, that the evening meal is the most consistent of the day. This is understandable, since the day is generally spent hunting for food that will be eaten in the evening."
--The Kung Hunter Gatherers of Botswana. "Members move out of camp each day individually or in small groups to work through the surrounding range and return in the evening to pool the collected resources for the evening meal."
--Hawaiians, Tahitians, Fijians and other Oceanic peoples (pre-westernization). 'Typically, meals, as defined by Westerners, were consumed once or twice a day. . . Oliver (1989) described the main meal, usually freshly cooked, as generally eaten in the late afternoon after the day’s work was over."

The most consistent daily eating pattern that is beginning to emerge from the ethnographic literature in hunter-gatherers is that of a large single meal which was consumed in the late afternoon or evening. A midday meal or lunch was rarely or never consumed and a small breakfast (consisting of the remainders of the previous evening meal) was sometimes eaten. Some snacking may have occurred during daily gathering, however the bulk of the daily calories were taken in the late afternoon or evening. This pattern of eating could be described as intermittent fasting relative to the typical Western pattern, particularly when daily gathering or hunting were unsuccessful or marginal. There is wisdom in the ways of our hunter gatherer ancestors, and perhaps it is time to re-think three squares a day.


In other words, the notion of "grazing," or eating small meals or snacks throughout the day, is an unnatural situation. It is directly contrary to the evolutionarily more appropriate large meal followed by periods of no eating or small occasional meals.

I stress this point because I see that the notion of grazing has seized hold of many people's thinking. In my view, grazing is a destructive practice that is self-indulgent, unnecessary, and simply fulfills the perverse non-stop hunger impulse fueled by modern carbohydrate foods.

Eliminate wheat, cornstarch, and sugars and you will find that grazing is a repulsive impulse that equates with gorging.

Even mummies do it

20. November 2009 William Davis (16)

Lady Rai, nursemaid to Queen Nefertari of Egypt, died in 1530 BC, somewhere between the age of 30 and 40 years. Her mummy is preserved in the Egyptian National museum of Antiquities in Cairo.

A CT scan of her thoracic aorta revealed calcium, representing aortic atherosclerosis, reported by Allam et al (including my friend from The Wisconsin Heart Hospital, Dr. Sam Wann, who provided me a blow-by-blow tale of this really fascinating project). Ladi Rai and 14 other Egyptian mummies were found to have vascular calcification of a total of 22 mummies scanned. (The hearts of the mummies were too degenerated to make out any coronary calcium.)

But why would people of that age have developed atherosclerosis?

The authors of the study comment that "Our findings that atherosclerosis was not infrequent among middle-aged and older ancient Egyptians of high social status challenges the view that it is a disease of modern humans. . . Although ancient Egyptians did not smoke tobacco or eat processed food or presumably lead sedentary lives, they were not hunter-gatherers. [Emphasis mine.] Agriculture was well established in ancient Egypt and meat consumption appers to have been common among those of high social status."

Fascinating. But I don't think that I'd blame meat consumption. Egyptians were also known to have cultivated grains, including wheat, and frequently consumed such sweet delicacies as dates and figs. Egyptians were also apparently beer drinkers. Unfortunately, no beer steins were seen in any of the scans.

Life Extension article on iodine

17. November 2009 William Davis (25)
Here's a link to my recent article in Life Extension Magazine on iodine:

Halt on Salt Sparks Iodine Deficiency

Iodized salt, a concept introduced into the U.S. by the FDA in 1924, slowly eliminated goiter (enlarged thyroid glands), along with an enormous amount of thyroid disease, heart attack, mental impairment, and death. The simple addition of iodine to salt ensured that salt-using Americans obtained enough iodine sufficient to not have a goiter.

Now that the FDA, goiters long forgotten from their memories, urges Americans to reduce salt, what has happened to our iodine?

I talk at length about this issue in the Life Extension article.

The healthiest people are the most iodine deficient

16. November 2009 William Davis (19)
Here's an informal observation.

The healthiest people are the most iodine deficient.

The healthier you are, the more likely you are to:

--Avoid junk foods--30% of which have some iodine from salt
--Avoid overuse of iodized salt
--Exercise--Sweating causes large losses of iodine.

So the healthy-eating, exercising person is the one most likely to show iodine deficiency: gradually enlarged thyroid gland (in the neck), declining thyroid function. Over time, if iodine deficiency persists, excessive sensitivity to iodine develops, as well as abnormal thyroid conditions like overactive nodules.

Even subtle levels of thyroid dysfunction act as a potent coronary risk factor.

It's the score, stupid

14. November 2009 William Davis (4)
Sal has had 3 heart scans. (He was not on the Track Your Plaque program.) His scores:

March, 2006: 439

April, 2007: 573

October, 2009: 799

Presented with the 39% increase from April, 2007 to October, 2009, Sal's doctor responded, "I don't understand. Your LDL cholesterol is fine."

This is the sort of drug-driven, cholesterol-minded thinking that characterizes 90% of primary care and cardiologists' practices: "Cholesterol is fine; therefore, you must be fine, too."

No. Absolutely not.

The data are clear: Heart scan scores that continue to increase at this rate predict high risk for cardiovascular events. Unfortunately, when my colleagues hear this, they respond by scheduling a heart catheterization to prevent heart attack--a practice that has never been shown to be effective and, in my view, constitutes malpractice (i.e., performing heart procedures in people with no symptoms and with either no stress test or a normal stress test).

It's the score, stupid! It's not the LDL cholesterol. Pay attention to the increasing heart scan score and you will know that the disease is progressing at an alarming rate. Accepting this fact will set you and your doctor on the track to ask "Why?"

That's when you start to uncover all the dozens of other reasons that plaque can grow that have nothing to do with LDL cholesterol or statin drugs.

Heart Scan Blog Redux: Cheers to flavonoids

13. November 2009 William Davis (32)
Because in Track Your Plaque we've been thinking a lot about anthocyanins, here's a rerun of a previous Heart Scan Blog post about red wine. (Anthocyanins are among the interesting flavonoids in red wine, along with resveratrol and quercetin.)


The case in favor of healthful flavonoids seems to grow bit by bit.

Flavonoids such as procyanadins in wine and chocolate, catechins in tea, and those in walnuts, pomegranates, and pycnogenol (pine bark extract) are suspected to block oxidation of LDL (preventing its entry into plaque), normalize abnormal endothelial constriction, and yield platelet-blocking effects (preventing blood clots).

Dr. Roger Corder is a prolific author of many scientific papers detailing his research into the flavonoids of foods, but wine in particular. He summarizes his findings in a recent book, The Red Wine Diet. Contrary to the obvious vying-for-prime-time title, Dr. Corder's compilation is probably the best mainstream discussion of flavonoids in foods and wines that I've come across. Although it would have been more entertaining if peppered with more wit and humans interest, given the topic, its straightfoward, semi-academic telling of the story makes his points effectively.

Among the important observations Corder makes is that regions of the world with the greatest longevity also correspond to regions with the highest procyanidin flavonoids in their wines.




Regarding the variable flavonoid content of wines, he states:

Although differences in the amount of procyanidins in red wine clearly occur because of the grape variety and the vineyard environment, the winemaker holds the key to what ends up in the bottle. The most important aspect of the winemaking process for ensuring high procyanidins in red wines is the contact time between the liquid and the grape seeds during fermentation when the alcohol concentration reaches about 6 percent. Depending on the fermentation temperature, it may be two to three days or more before this extraction process starts. Grape skins float and seeds sink, so the number of times they are pushed down and stirred into the fermenting wine also increases extraction of procyanidins. Even so, extraction is a slow process and, after fermentation is complete, many red wines are left to macerate with their seeds and skins for days or even weeks in order to extract all the color, flavor, and tannins. Wines that have a contact time of less than seven days will have a relatively low level of procyanidins. Wines with a contact time of ten to fourteen days have decent levels, and those with contact times of three weeks or more have the highest.

He points out that deeply-colored reds are more likely to be richer in procyanidins; mass-produced wines that are usually "house-grade" served at bars and restaurants tend to be low. Some are close to zero.

Wines rich in procyanidins provide several-fold more, such that a single glass can provide the same purported health benefit as several glasses of a procyanidin-poor wine.

So how do various wines stack up in procyanidin content? Here's an abbreviated list from his book:

Australian--tend to be low, except for Australian Cabernet Sauvignon which is moderate.

Chile--only Cabernet Sauvignon stands out, then only moderate in content.

France--Where to start? The French, of course, are the perennial masters of wine, and prolonged contact with skins and seeds is usually taken for granted in many varieties of wine. Each wine region (French wines are generally designated by region, not by variety of grape) can also vary widely in flavonoid content. Nonetheless, Bordeaux rate moderately; Burgundy low to moderate (except the village of Pommard); Languedoc-Roussillon moderate to high (and many great bargains in my experience, since these producers live in the shadow of its northern Bordeaux neighbors); Rhone (Cote du Rhone) moderate to high, though beware of their powerful "barnyard" character upon opening; decanting is wise.

Italy--Much red Italian wine is made from the Sangiovese grape and called variously Chianti, Valpolicella, and "super-Tuscan" when blended with other varietals. Corder rates the southern Italian wines from Sicily, Sardinia, and the mainland as high in procyanidins; most northern varieties are moderate.

Spain--Moderate in general.

United States--Though his comments are disappointingly scanty on the U.S., he points out that Cabernet Sauvignon is the standout for procyanidin content. He mentions only the Napa/Sonoma regions, unfortunately. (I'd like to know how the San Diego-Temecula and Virginian wines fare, for instance.)

The winner in procyanidin content is a variety grown in the Gers region of southwest France, a region with superior longevity of its residents. The wines here are made with the tannat grape within the Madiran appellation; wines labeled "Madiran" must contain 40% or more tannat to be so labeled (such is a quirk of French wine regulation). Among the producers Dr. Corder lists are Chateau de Sabazan, Chateau Saint-Go, Chateau du Bascou, Domaine Labranche Laffont, and Chateau d'Aydie. (A more complete list can be found in his book.)

How does this all figure into the Track Your Plaque program? Can you succeed without red wine? Of course you can. I doubt you could do it, however, without some attention to flavonoid-rich food sources, whether they come from spinach, tea, chocolate, beets, pomegranates, or red wine.

Though my wife and I love wine, I confess that I've never personally drank or even seen a French Madiran wine. Any wine afficionados with some advice?

Can wheat elimination cure ulcerative colitis?

13. November 2009 William Davis (0)
Tammy is a 36-year old mother of three young children. Since age 20, she has suffered with the debilitating symptoms of ulcerative colitis: constant, gnawing abdominal pain; frequent diarrhea, often bloody.



Tammy has had to take several medications, some with significant side-effects, all of which provided only partial relief from the pain and diarrhea. Her gastroenterologist and surgeon were planning a colectomy (removal of the colon) with creation of an ileostomy (rerouting of the small intestine to the abdominal surface, which would require Tammy to wear an ileostomy bag under her clothes for the rest of her life).



Although Tammy had previously tested negative for celiac disease (an allergic sensitivity to the gluten in wheat products), I urged her to attempt a trial of a wheat-free diet. Having witnessed many people experience relief from irritable bowel syndrome, acid reflux, and other common gastrointestinal complaints, all while trying to reduce blood sugar and small LDL, I'd hoped that Tammy would obtain at least some small improvement in her terrible symptoms.



I therefore urged Tammy to try it. After all, what was there to lose? Tammy grudgingly agreed.



She returned 6 months later. Her report: She had lost 38 lbs, virtually all of it within the first 6-8 weeks. Her diarrhea and cramping were not better, but gone. She was down to a single medicine from her former list of drugs.



I am unsure what proportion of people with ulcerative colitis or other inflammatory bowel diseases like Crohn's will experience a result like Tammy's. Perhaps it's only a minority. But I take this another piece of evidence that this enormously destructive thing called wheat has no place in the human diet.



We have no facts or figures on the prevalence of various forms of wheat intolerance in the U.S. When I contacted the Celiac Disease Foundation, they had no figures on the number of fatalities per year in the U.S. from celiac disease. But if there are 2-3 million Americans with celiac disease, there are probably 100 times that many people with various forms of wheat intolerance.



Postprandial pile-up with fructose

12. November 2009 William Davis (20)
Heart disease is likely caused in the after-eating, postprandial period. That's why the practice of grazing, eating many small meals throughout the day, can potentially increase heart disease risk. Eating often can lead to the phenomenon I call triglyceride and chylomicron "stacking," or the piling up of postprandial breakdown products in the blood stream.

Different fatty acid fractions generate different postprandial patterns. But so do different sugars. Fructose, in particular, is an especially potent agent that magnifies the postprandial patterns. (See Goodbye, fructose.)

Take a look at the graphs from the exhaustive University of California study by Stanhope et al, 2009:



From Stanhope KL et al, J Clin Invest 2009. Click on image to make larger.

The left graphs show the triglyceride effects of adding glucose-sweetened drinks (not sucrose) to the study participants' diets. The right graphs show the triglyceride effects of adding fructose-sweetened drinks.

Note that fructose causes enormous "stacking" of triglycerides, meaning that postprandial chylomicrons and VLDL particles are accumulating. (This study also showed a 4-fold greater increase in abdominal fat and 45% increase in small LDL particles with fructose.)

It means that low-fat salad dressings, sodas, ketchup, spaghetti sauce, and all the other foods made with high-fructose corn syrup not only make you fat, but also magnifies the severity of postprandial lipoprotein stacking, a phenomenon that leads to more atherosclerotic plaque.

Track Your Plaque: Safer at any score

11. November 2009 William Davis (0)
Imagine two people.

Tom is a 50-year old man. Tom's initial heart scan score was 500--a concerning score that carries a 5% risk for heart attack per year.

Harry is also 50 years old. His heart scan score is 100--also a concerning score, but not to the same degree as Tom's much higher score.

Tom follows the Track Your Plaque program. He achieves the 60:60:60 lipid targets; chooses healthy foods, including elimination of wheat; takes fish oil at a therapeutic dose; increase his blood vitamin D level to 60-70 ng/ml, etc. One year later, Tom's heart scan score is 400, representing a 20% reduction from his starting score.

Harry, on the other hand, doesn't understand the implications of his score. Neither does his doctor. He's casually provided a prescription for a cholesterol drug by his doctor, a brief admonition to follow a low-fat diet, and little else. One year later, Harry's heart scan score is 200, a doubling (100% increase) of the original score.

At this point, we're left with Tom having a score of 400, Harry with a score of 200. That is, Tom has twice Harry's score, 200 points higher. Who's better off?

Tom with the score of 400 is better off. Even though he has a significantly higher score, Tom's plaque is regressing. Tom's plaque is therefore quiescent with active components being extracted, inflammation subsiding, the artery in a more relaxed state, etc.

Harry's plaque, in contrast, is active and growing: inflammatory cells are abundant and producing enzymes that degrade supportive tissue, constrictive factors are released that cause the artery to pinch partially closed, fatty materials accumulate and trigger a cascade of abnormal responses.

So it's not just the score--the quantity of atherosclerotic plaque present--but the state of activity of the plaque: Is it growing, is it being reduced? Is there escalating or subsiding inflammation? Is plaque filled with degradative enzymes or quiescent?

Following the Track Your Plaque program therefore leads us to the notion that it's not the score that's most important; the most important thing is what you're doing about it. We sometimes say that Track Your Plaque makes you safer at any score.
Fasting with green tea

Fasting with green tea

1. June 2011 William Davis (34)
I've been playing around with brief (18-24 hour) fasts with the use of green tea. Of the several variations on fasting, such as juice "fasts,"  I've been most impressed with the green tea experience.

While the weight loss effects of daily green tea consumption are modest, there seems to be a specific satiety effect that has now been demonstrated in multiple studies, such as this and this. In other words, green tea, through an uncertain mechanism, reduces hunger. The effect is not just due to volume, since the effect cannot be reproduced with hot water alone.

I therefore wondered whether green tea might be a useful beverage to consume during a fast, as it might take the "edge" off of hunger. While hunger during a fast in the wheat-free is far less than wheat-consuming humans, there is indeed an occasional twinge of hunger felt.

So I tried it, brewing a fresh 6-8 oz cup evert two hours or so. I brewed a pot in the morning while at home, followed by brewing single cups using my tea infuser at the office. Whenever I began to experience a hunger pang, I brewed another cup and sipped it. I was pleasantly surprised that hunger was considerably reduced. I sailed through my last 18 hours, for instance, effortlessly. The process was actually quite pleasant.

I brew loose Chinese bancha, sencha, and chunmee teas and Japanese gyokuro tea. Gyokuro is my favorite, but also the most expensive. Bancha is more affordable and I've used that most frequently.

If anyone else gives this a try, please report back your experience.

    I would like to know if this works with iced green tea as well. I used a method of one meal per day to loose 50+ pounds. I found it pretty easy, all in all, but have regained about 20 now and need to get back on it. I think I will give iced green tea a try! (I'm not crazy about hot green tea, but like it fine iced)

    I use tea as a method of extending eating intervals.  It works well.  I'm sure a lot of it has to do with the "upper" effect.  Ie.  uppers reduce appetite as a result of blocked sensory.

    I find fasting and sensory blocking to be counter-productive.

    May be other effects but caffeine and it's cousin theobromine in the tea are pretty reliable appetite suppressants.  But isn't getting jacked up (even if only a little) a bit counter productive to some of the potential benefits of fasting?  The idea is to rest your physiology while catabolism is in full swing. Activating the sympathetic nervous system so you don't have to experience the sensations you don't like during the early stages of fasting does not seem to me to really promote that.

    Yes, green tea reduces my hunger; I just use Tetley in the bag. Some of the greens do not have a satiating effect on me, nor do any of the black teas. Coffee increases hunger for me. Bullion cubes or OXO packets also help. I make a 1.5 l thermos, and suck on that until its done. Some days 3 or 4 of them in a day. I think I have more hunger than most people, but I am down 55 kgs, 2 to 4 years ago and have been down for 2 years.

    The other thing that helps me is chew-able Vitamin C, a couple of 500s any time I feel hungry. It seems to raise BG, possible due to BG sparing, as it is required for far oxidation, or inside cell far transport, depending on who is explaining. Two 500's raise my BG form 4.0 to 5.3 -- OK US 72 to 95.
    I am off wheat mostly; occasionally Clam chowder, sausages, and a few crackers for low BG issues. One cracker raises BG 1.5 at 15 mins.

    Thanks for the one hour BG idea. Some of my higher protein meals were a problem, like 280 Calories of canned salmon ran my BG to 9.0 (OK 162). And my doctor says I an not diabetic but my a.m. BG sure is erratic, 4.0 to 6.2 this week.

    Hey Phyllis, I'm with you. I have been drinking 4 cups green tea made with tea bags and then chilled and have noticed that I'm not as hungry but didn't really connect it with the tea itself. I need to lose 50 lbs and I like the idea of one meal a day.

    Green tea, or any tea actually, makes me a little ill on an empty stomach.  Not sure but believe it is the tannins.  I also was consuming a lot of green/white tea while fasting and I just felt really acidic and my face got red splotches, which seems to coincide with acidity.  I know the net result is supposed to be alkaline for green/white tea but that has not been my experience.  Recently, I've been adding a tablespoon of apple cider vinager to a cup of warm water.  Went a fairly easy 18 hours today but did break down and had four or five macadamia nuts around 12 hours in.

    After millennia of human starvation, to think that we still have tons to learn about fasting used for health purposes!

    Phyllis--While I've not tried it personally, nor do I know of any formal data, I expect that iced green tea--provided it is real brewed green tea, and not the bottled variety--should work every bit as well.

    I am unable to drink green tea at all on an empty stomach, I will absolutely throw up if I do.  I end up with pullovertothesideoftheroadI'mgoingtopukeyesseriously!".   I actually threw up all over my suit once which was really special.  Green tea with food often makes me queasy as well.  I am allergic to oak so I think there may be a tannin connection as some heavy oak wines are problematic for me.

    For those who get dizzy on green tea, try puerh tea.  It is a fermented green tea that is also much lower in caffeine and it taste much better than green.  It is the equivalent of drinking an aged red wine over 2 buck chuck.

    This question has been around for quite some time,  but no one seems to know the answer for certain.

    Theoretically at least, consuming antioxidants during fasting could be detrimental to autophagy (removing "junk" cells), since antioxidants might suppress the stress response from fasting. This is why some studies show antioxidants and exercise are a bad combination -- you *want* some stress to happen so that the body can adapt to it.

    Then again, there is the theory that small amounts of antioxidants actually work through the same mechanism as fasting and exercise -- hormesis. In which case fasting + antioxidants might complement each other. But that's just speculation.

    What we do know from studies is that green tea seems to increase weight loss, for example when combined with calorie restriction (and thus should apply to fasting):

    http://inhumanexperiment.blogspot.com/2009/04/green-tea-increases-weight-loss-during.html

    And when combined with exercise:

    http://inhumanexperiment.blogspot.com/2009/03/green-tea-extract-increases-insulin.html
    http://inhumanexperiment.blogspot.com/2009/02/green-tea-extract-enhances-abdominal.html

    And when combined with capsaicin (from chilli pepper), it reduces the feeling of hunger and thus calorie intake:

    http://inhumanexperiment.blogspot.com/2009/04/green-tea-and-capsaicin-reduce-hunger.html

    So all in all, whatever the mechanism is, if you're fasting just for the sake of losing weight, I'd say green tea is a pretty good bet.

    Would depend on the length of fasts, but the East Stop East method advocates two fasts per week.  My fasts are now usually shorter, as they kind of trained me to stop grazing. I usually don't bother with breakfast now. The more you eat, the more you want to eat sometimes.

    Yes, I completely agree with you! I went 90% wheat and sugar free from November 2010 to February 2011 and lost a whopping 2 pounds. It wasn't until I went to 95% or more wheat free that I was able to start losing weight. I am now 100% wheat free and I have lost 36.2 pounds in 15 weeks. I have also been able to significantly cut my caloric intake to 500-700 calories per day (sometimes less than 500) using iced jasmine green tea. I truly believe that a diet that is lower in calories is better for health. I typically drink 6-8 glasses a day and I really enjoy it. It helps immensely with any hunger I may have and completely satisfies my sense to eat. I use any of the varieties available in tea bag (Numi, Two Leaves and a Bud, Stash, and Mighty Leaf are my favorites). I typically choose whatever's on sale. I also drink a full glass every morning prior to eating and that also seems to stimulate my colon which is a bonus as well when consuming such low caloric counts.

    On a cholesterol and BG level, my family genetics are something that should be studied. While I started my diet at 234.8# on 2/15/2011 (I'm 5'3" and 47 y/o female) my total cholesterol was 167 and my HDL was 54. My 102 y/o grandmother however, has a total cholesterol of 155 and an HDL of 115! My 76 y/o mother also has the same great results but her HDL is "only" 109. Neither of them are on any medication for cholesterol and both of them eat a diet fully based on things we berate on this blog (cookies, bread, ice cream, fried foods, etc). Neither are overweight either. I'm eager to see what my levels become when I reach my goal weight. Maybe I can surpass that HDL of 115!

    About 15 years ago I went on a fast and had only water.  The fast lasted for 10 days.  No green tea.  Just water.  After 18 hours, I completely lost any hunger.  Meanwhile I continued to cook meals for my family.  I also continued to go to work every day.

    The experience seemed wonderful.  I had been suffering badly from asthma, and all symptoms disappeared!  I could have kept going forever without eating.  However, after 10 days I started to have problems with urination.  I began excreting small, hard pellets.

    I went to the doctor, and he exploded.  "You bloody fool!" he said.  I had altered the ketone content of my blood.

    So I started eating again.  My first meal was brown rice (no salt).  It was the most beautiful meal I ever had.  Gradually I returned to normal eating.  Gradually I returned to my asthma symptoms. Gradually all meals started tasting the same.

    Did I lose weight?  I'm not sure, as my ketone problem overshadowed all else.  Did I need green tea or anything else to curb my appetite?  No, plain water (not even distilled or bottled water, but tap water) was good enough. Do I recommend fasting?  In moderation.  10 days is far too long.

    There is only one problem with green tea: Pesticides.
    Most green tea is imported from India or China because it is the cheapest. On testing, a serious amount of pesticides, fungicides, microcides is found regularly. I wonder if this diminishes the health aspect of green tea.
    I used to buy organic green tea from Japan but after Fukushima that option is also out.
    Still, certified organic is the only option left, I suppose.

    Started IF HFLC diet three months ago. 30 lbs lost and A1c down to
    5.1 !! (was 6.7 ) . Curiously I have been drinking green tea during the daily 18 hour fasts and hunger is a rare occurance,  hunger pains last only a few seconds. The tea helps,  body and mind trained to not think about food until
    nightly free for all. Thank you, Dr. Davis and contributors>

    Flouride IS an issue with green tea. There are known cases of flourde poisoning with excessive green tea drinking - woman drinking equivalent of 20-30 green tea cups per day. This isn't something to worry about on regular usage but if you do it on IF with reduced nutrient input and more frequently to reduce appetite it can become a problem.

    White tea has lower content of fluoride as it is harvested when plant is still young. It is much more expensive but overall better then green tea due to less processing and lower fluoride content.

    Coffee works for me absolutely amazing in reducing hunger. To some people, however, it works the opposite way. My friend develops hand tremor, nervousness, and heat. The same thing she got from the green tea but not other teas. Caffeine might be problematic for some I guess, or maybe tannin. We are currently in the process of isolation of such substance.

    To reduce appetite, I found the following valuable:
    - Garlic, fresh, in tomato juice (parsley can be included to block the smell). The capsule doesn't work.
    - High intensity exercise, short bursts of 15-20 minutes will shut down digestive engine and you will not be able to eat for hour at least.
    - Marijuana restriction - its usage during fat loss might be problematic due to activation of CB1/anandamide system.
    - Periodic IF can learn body to handle prolonged food abstinence. I find that 16-24 hours fast is enough.
    - Almonds, 10-15g, are cool, especially if you tend to go crazy before sleep - its mostly fat which doesn't rise insulin during night. 2g CHO, 3.5g MUFA, 1g PUFA, 2g P is enough to make your hunger go down at least a bit and still keep your insulin down.
    - Water

    I would suggest extensive supplementation during IF - especially Vit C (at least 2g as frequent as possible), Mg, Iodine, Selenium, Idebenon.

    Drs. Davis or Taylor (or anyone else) have you noticed any issues with accumulated caffeine intake from multiple cups of Green Tea throughout the day?

    Dr. Davis, I hadn't heard about the dangers of pesticide use relating to green tea (as mentioned by Renfew, above)...is this a viable concern?  Since green tea is loaded with antioxidants, do the benefits outweigh the risks in this case?

    I have been drinking about two to three cups of Tazo Zen Green Tea for quite awhile now (hot, as well as chilled), and enjoy it very much.  It does seem to curb cravings quite well.  I also notice increased energy without the edgy side effects that coffee sometimes causes.  Before Tazo, I was not a big fan of the taste of green tea, but the Zen blend also contains lemon verbena, spearmint leaves and lemongrass, which enhances the flavor and makes it quite delicious--providing an "aromatherapy experience" along with the tea consumption.  Smile

    I drink the Tazo Zen Green Tea from Starbucks. I prefer this green tea over any others, however I have noticed extreme dizziness when I drink this tea. Has anyone experienced this? I even bought the tea bags to brew at home, I do not add any sweetener and love the taste. I occasionally drink black tea or soda and do not get the same dizzy feeling, therefore I believe it is not caffeine causing me to feel dizzy it's just green tea. Any suggestions or comments? I like the benefits of green tea but not sure it's worth the dizziness.

    Wacky. No, I'm not sure why this happens.

    Perhaps its some mixture or proportion of the theaflavins or other components. There are hundreds of green tea preparations available. It might be worth finding a happy alternative.

    I have been using green tea for years in weight loss.  You are right, it is not a "speedy" remedy and you will only recognize small affects it has, however, it does work.  On average, it is said that you can burn anywhere from 70 to 80 calories a day drinking green tea.  This is assuming you are drinking at least 3 to 4 cups daily.  It should be combined with water and a healthy diet and exercise.

    About the dizziness, I had severe vertigo in the middle of the night, i.e. at 3 am (my blood pressure was 130/100 pr 90), and the day and the night before sleeping, I consumed 4 mugs of green tea. The vertigo was associated with vomiting (which relieved the vertigo for a while). The vertigo lasted till the next day (vomited 4x). The green tea was a gift from a friend who came back from China-loose dried leaves. After that episode, I think I can't make myself to drink green tea again.

    I sometimes do a morning 'flush' of green tea, up to 4 freshly brewed mugfuls, with the addition of a squeeze of fresh lemon, which complements the taste and gives extra benefits, vitamin c and supporting detoxification.

    I recently saw a BBC documentary which demonstrated an optimal brew time of 7 minutes for maximum anti-oxidant release.

    Also, the cooled teabags are an excellent beauty treatment for the eye area, squeeze excess moisture and relax for a few minutes.

    Am reluctant to extend beyond midday due to stimulating effect of caffeine, how about switching to other teas that deliver other useful benefits? Ginger, fennel, liquorice come to mind.

    Blessings of health
