The Track Your Plaque guide to getting grotesquely overweight

If you'd like to gain huge quantities of weight, here's a number of helpful tips:

1) Follow the advice of food manufacturers and eat the products they label "healthy", or "heart healthy", or "part of a nutritious breakfast" etc., like Shredded Wheat cereal, pretzels ("a low-fat snack"!), low- or non-fat salad dressings.

2) Cut your morning calorie intake by skipping breakfast.

3) Hang around with other heavy people. They will confirm that it's okay to be overweight.

4) Call walking your dog "exercise".

5) Get a sedentary desk job. Use your swivel desk chair to scoot about whenever possible, rather than getting up to do things.

6) Say "I've worked hard all week long. Weekends are for relaxing, not for physical activities. I deserve a rest."

7) Eat foods without thinking about it: Eat chips while watching football, eat while on the phone, daydream over the sink.

8) Eat to provide comfort when stressed.

9) Eat foods that have sentimental value, whether or not they're good for you: Freshly-baked cakes that remind you of Mom, Pop Tarts that you used to carry in your lunchbox when you were a kid, hot dogs just like Dad would buy at the baseball stadium.

10) Cut back on sleep and generate insatiable starch cravings.

11) Stack your shelves at home with great variety. That way, you'll always have something to suit your mood.

12) Say to your spouse: "It's none of your damn business what I eat! I'm a grown man/woman!" Prove it by over-indulging in obviously unhealthy foods.

13) Tell yourself that you're just too busy to pay attention to food choices. Just grab whatever you can out of a convenience store or vending machine.

See, it's easy! And that just a start.

Of course, I don't really want you to do any of these things. But if you see yourself in any of the above, and you're struggling with weight, you should seriously rethink your approach.

Your heart scan is just a "false positive"

I've seen this happen many times. Despite the great media exposure and the growing acceptance of my colleagues, heart scans still trigger wrong advice. I had another example in the office today.

Henry got a CT heart scan in 2004. His score: 574. In his mid-50s, this placed him in the 90th percentile, with a heart attack risk of 4% per year. Henry was advised to see a cardiologist.

The cardiologist advised Henry, "Oh, that's just a 'false positive'. It's not true. You don't have any heart disease. Sometimes calcium just accumulates on the outside of the arteries and gives you these misleading tests. I wish they'd stop doing them." He then proceeded to advise Henry that he needed a nuclear stress test every two years ($4000 each time, by the way). No attempt was made to question why his heart scan score was high, since the entire process was outright dismissed as nonsense.

I'm still shocked when I hear this, despite having heard these inane responses for the past decade. Of course, Henry's heart scan was not a false positive, it was a completely true positive. I'm grateful that nothing bad happened to Henry through two years of negligence, though his heart scan score is likely around 970, given the expected, untreated rate of increase of 30%.

The cardiologist did a grave disservice to Henry: He misled him due to his ignorance and lack of understanding. I wish Henry had asked the cardiologist whether he had read any of the thousands of studies now available validating CT heart scans. I doubt he's bothered to read more than the title. The cardiologist is lucky (as is Henry) that nothing bad happened in those two years.

Do false positives occur as the cardiologist suggested? They do, but they're very rare. There's a rare phenomenon of "medial calcification" that occurs in smokers and others, but it is quite unusual. >99% of the time, coronary calcium means you have coronary plaque--even if the doctor is too poorly informed to recognize it.

What's better than a heart scan?


Do you know what's better than a heart scan?

Two heart scans. No other method can provide better feedback on the results of your program.

Say you've made efforts to correct high LDL; lost weight to raise HDL and reduce small LDL; added soluble fibers, nuts, and dramatically reduced wheat products; take fish oil, vitamin D, and follow a flavonoid-rich diet. Has it worked?

After a year or so of your program, that's when another heart scan can give you invaluable feedback on whether it's been successful. I tell my patients that it's relatively easy to correct lipid and lipoprotein abnormalities. The difficult part is to know when it's good enough. Is your LDL of 67 mg/dl and HDL of 50 mg/dl good enough? Another heart scan score is the best way I know of to find out.

Variation in plaque growth differs hugely from one person to another, even at equivalent lipoprotein values. Why? Lots of reasons. Humans are inconsistent day to day. Lipoproteins, being a snapshot in time and not a cumulative value, change somewhat from day to day. There's also the possibility of unmeasured, unrecognized factors that influence coronary plaque growth. We may not be smart enough to identify these hidden factors yet. But your heart scan score will incorporate the effects of these hidden factors.

Ideally, we aim for zero growth in plaque (no change in score) or a reduction. But, particularly in the first year, 10% or less plaque growth is still a good result that predicts much reduced risk of heart attack. More than 20% per year and your program needs more work--or else you know what's ahead.

Lipids are snapshots in time; heart scans are cumulative

Let me paint a picture. It's fictional, though a very real portrait of how things truly happen in life.

Michael is an unsuspecting 40-year old man. He hasn't undergone any testing: no heart scan, no lipids or lipoproteins. But we have x-ray vision, and we can see what's going on inside of him. (We can't, of course, but we're just pretending.) Average build, average lifestyle habits, nothing extraordinary about him. His lipids/lipoproteins at age 40:

--LDL cholesterol 150 mg/dl
--HDL cholesterol 38 mg/dl
--Triglycerides 160 mg/dl
--Small LDL 70% of all LDL

At age 40, with this panel, his heart scan score is 100. That's high for a 40-year old male.

Fast forward 10 years. Michael is now 50 years old. Michael prides himself on the fact that, over the past 10 years, he's felt fine, hasn't gained a single pound, and remains as active at 50 as he did in 40. In other words, nothing has changed except that he's 10 years older. His lipids and lipoproteins:

--LDL cholesterol 150 mg/dl
--HDL cholesterol 38 mg/dl
--Triglycerides 160 mg/dl
--Small LDL 70% of all LDL

Some of you might correctly point out that just simple aging can cause some deterioration in lipids and lipoproteins, but we're going to ignore these relatively modest issues for now.)

Lipids and lipoproteins are, therefore, unchanged. Michael's heart scan score: 1380, or an approximate 30% annual increase in score. (Since Michael didn't know about his score, he took no corrective/preventive action.)

My point: If we were to make our judgment about Michael's heart disease risk by looking at lipids or lipoproteins, they would'nt tell us where he stood with regards to heart disease risk. His lipids and lipoproteins were, in fact, the same at age 50 as they were at age 40. That's because measures of risk like this are snapshots in time.

In contrast, the heart scan score reflects the cumulative effects of life and lipids/lipoproteins up until the day you got your scan.

Which measure do you think is a better gauge of heart attack risk? I think the answer's obvious.

The recognition of the metabolic syndrome as a distinct collection of factors that raise heart disease risk has been a great step forward in helping us understand many of the causes behind heart disease.

Curiously, there's not complete agreement on precisely how to define metabolic syndrome. The American Heart Association and the National Heart, Lung, and Blood Institute issued a concensus statement in 2005 that "defined" metabolic syndrome as anyone having any 3 of the 5 following signs:





Waist size 40 inches or greater in men; 35 inches or greater in women

Triglycerides 150 mg/dL or greater (or treatment for high triglycerides)

HDL-C <40 mg/dL in men; <50 mg/dL in women (or treatment for reduced HDL-C)

Blood Pressure >130 mmHg systolic; or >85 mmHg diastolic (or drug treatment for hypertension)

Glucose (fasting) >100 mg/dL (or drug treatment for elevated glucose)


Using this definition, it has become clear that meeting these criteria triple your risk of heart attack.

But can you have the risk of metabolic syndrome even without meeting the criteria? What if your waste size (male) is, 36 inches, not the 40 inches required to meet that criterion; and your triglycerides are 160, but you meet none of the other requirements?

In our experience, you certainly can carry the same risk. Why? The crude criteria developed for the primary practitioner tries to employ pedestrian, everyday measures.

We see people every day who do not meet the criteria of the metabolic syndrome yet have hidden factors that still confer the same risk. This includes small LDL; a lack of healthy large HDL despite a normal total HDL; postprandial IDL; exercise-induced high blood pressure; and inflammation. These are all associated with the metabolic syndrome, too, but they are not part of the standard definition.

I take issue in particular with the waist requirement. This one measure has, in fact, gotten lots of press lately. Some people have even claimed that waist size is the only requirement necessary to diagnose metabolic syndrome.

Our experience is that features of the metabolic syndrome can occur at any waist size, though it increases in likelihood and severity the larger the waist size. I have seen hundreds of instances in which waist size was 32-38 inches in a male, far less than 35 inches in a female, yet small LDL is wildly out of control, IDL is sky high, and C-reactive protein is markedly increased. These people obtain substantial risk from these patterns, though they don't meet the standard definition.

To me, having to meet the waist requirement for recogition of metabolic syndrome is like finally accepting that you have breast cancer when you feel the two-inch mass in your breast--it's too late.

Recognize that the standard definition when you seen it is a crude tool meant for broad consumption. You and I can do far better.

What role DHEA?




DHEA, the adrenal gland hormone, has suffered its share of ups and downs over the years.

Initially, DHEA was held up as the fountain of youth with hopes of turning back the clock 20 years. Such extravagant dreams have not held up. But DHEA can still be helpful for your program.

All of us had oodles of DHEA in our bodies when we were in our 20s and 30s. Gradually diminishing levels usually reach nearly blood levels of around zero by age 70.



In our heart disease prevention program, of course, we aim to stop or reduce your CT heart scan score. Does DHEA reduce your score? No, it most certainly does not. But it can be helpful for gaining control over some of the causes behind coronary plaque.

For instance, DHEA can:

--Help reduce abdominal fat and increase muscle mass (slightly)
--Provide more physical stamina.
--Boost mood.
--It may modestly reduce some of the phenomena associated with the metabolic syndrome (high blood pressure, high blood sugar, high insulin, low HDL, small LDL, etc.)

In my experience, people who feel better do better on their overall program. If you're always tired and run down and run out of steam by 3 pm, I won't see you riding your bicycle outdoors or at the aerobics class. But if you're bursting with energy until you put your head on the pillow, you're more inclined to walk, bike, dance, play with the kids, dance, take Tai Chi, etc.

Some downsides to DHEA: Some people experience aggression. Backing off on the dose usually relieves it. Also, sleeplessness. Taking your DHEA in the morning usually fixes it.



The dose is best tailored to your age and blood levels. People less than 40 years old should not take DHEA. The older you are, the higher the dose, though we rarely ever have to exceed 50 mg per day. If you've never had a blood level and your doctor refuses to obtain one, 25 mg per day is a reasonable dose (10-15 mg in women 40-50 years old). It's always best to discuss your supplement use, particularly agents like DHEA, with your doctor.

Brainwashed!

At a social gathering this weekend, as we humans like to do, someone asked me what I did for a living. I told him I was a cardiologist.

"What hospital do you work at?" he asked.

This is invariably the response I get whenever I tell people what I do. I wouldn't make much of it except that it happens just about every time.

This indicates to me just how successful hospitals, my colleagues, cardiac device manufacturers, and others supporting the status quo in heart care, have been in persuading us that the place for heart disease is the hospital--period.

Tense families, drama, high-tech...It all takes place in the hospital.

Yet the people destined to be the fodder for hospital heart care are presently well, mostly unaware of what the future holds. Also unaware that heart disease is readily, easily, inexpensively, and accurately identifiable. Ask anyone in the Track Your Plaque program who's had a CT heart scan.

We all need to rid ourselves of the idea that the hospital is the place for heart disease. If the coronary plaque behind heart attack is easy to detect and controllable, there's little or no need for the hospital for the vast majority of us.

In the majority of instances of coronary disease, the hospital should be the place for the non-compliant and the ill-informed, and not for those of us sufficiently motivated to know and do better. The formula is simple: 1) Quantify plaque with a CT heart scan, 2) Identify the causes, then 3) Correct the causes.

The Fanatic Cook: A fabulous Blog about food and nutrition

I came across this Blog authored by a nutritionist when it was highlighted on Blogger as an interesting site:

The Fanatic Cook at http://fanaticcook.blogspot.com/

I was thoroughly impressed with the insightful and entertaining commentary. I'd highly recommend this site to you for reading on nutrition. In particular, her coenzyme Q10 column was exceptionally well written and clear.(http://fanaticcook.blogspot.com/2005/02/statins-and-not-well-publicized-side.html)

Also read her column, Super NonFoods at http://fanaticcook.blogspot.com/2005/07/super-nonfoods.html.

There's also oodles of recipes, all for the taking.

Eggs: Good, bad, or indifferent?

Eggs have been in the center of the cholesterol controversy almost from the very start.

The traditional argument against eggs went that eggs, high in cholesterol (210-275 mg per egg)and with some saturated fat (1.5-2.5 grams per egg), raised blood cholesterol (and LDL). Out went the daily fried, scrambled, poached eggs that many Americans indulged in most mornings. (We replaced it with more breakfast cereals and other carbohydrate conveniences, then got enormously overweight.)





A large Harvard epidemiologic study in 1999 called this observation into question. They tracked the fate of 117,000 thousand people and then compared the rate of heart attack, death, and other cardiovascular events among various people correlated to the "dose" of eggs they ate. Egg intake varied from none to 7 or more per week. Lo and behold, people who ate more eggs appeared to not suffer more events.

This study, large and well-conducted by an internationally respected group of investigators, seem to reopen the gates for more egg consumption, though most Americans still consume eggs cautiously.

Deeper down in this study, however, was another observation: People with diabetes who ate 1 egg per day had double the risk of heart attack. Because this study was observational, no specific conclusion as to why could be drawn.

A new study conducted by a Brazilian group may shed some light. Healthy (non-diabetic) men were fed an emulsion of several eggs. Inclusion of plentiful yolks caused a dramatic slowing of fat clearance from the blood. Specifically, "chylomicron remnants" were abnormally persistent in the blood. Chylomicron remnants are potent causes of coronary plaque. (Chylomicron remnants can be measured fairly well by intermediate-density lipoprotein and VLDL by NMR, or IDL by VAP.)

Diabetics are know to have substantial disorders of after-meal fat clearance, including an excess of chylomicron remnants. Could the Brazilian observation be the explanation for the increased event rate in diabetics in the Harvard study? Interesting to speculate.

We continue to tell our patients that eating eggs in moderation is probably safe. After all, there are good things in eggs: the high protein in the egg white, lecithin in the yolk. It is the yolk's contents that are in question, not the white. Thus, you and I can eat all the egg whites (e.g., Egg Beaters) we want. It's the safety of yolks that are uncertain.

The abnormal after-eating effect suggested by the Brazilians opens up some very interesting questions and confirms that we should still be cautious in our intake of egg yolks. One yolk per day is clearly too much. What is safe? The exisitng information would suggest that, if you have diabetes, pre-diabetes, or a postprandial disorder (IDL, VLDL), you should minimize your egg yolk use, perhaps no more than 3 or so per week, preferably not all at one but spaced out to avoid the after-eating effect.

Others without postprandial disorders may safely eat more, perhaps 5 per week, but also not all at one but spaced out.

Track Your Plaque Members: Be sure to read our upcoming Special Report on Postprandial Disorders. It contains lots of info on what this important pattern is all about. Postprandial disorders are largely unexplored territory that hold great promise for tools to inhibit coronary plaque growth and drop your heart scan score. The Brazilian study is just one of many future studies that are likely to be released in future about this very fascinating area.

Diabetes is Track Your Plaque's Kryptonite!


If there's one thing I truly fear from a heart scan score reduction/coronary plaque regression standpoint, it's diabetes.

I saw a graphic illustration of this today. Roy came into the office after his 2nd heart scan. His first scan 14 months ago showed a score of 162. Roy started out weighing well over 300 lbs and with newly-diagnosed adult diabetes.

Roy put extraordinary effort into his program. He lost nearly 70 lbs by walking; cutting processed carbohydrates, greasy foods, and slashing overall calories. His lipoproteins, disastrous in the beginning, were falling into line, though HDL was still lagging in the low 40s, as Roy remains around 60 lbs overweight, even after the initial 70 lb loss.

Unfortunately, despite the huge loss in weight, Roy remains diabetic. On a drug called Actos, which enhances sensitivity to insulin, along with vitamin D to also enhance insulin response, his blood sugars remained in the overtly diabetic range.

Roy's repeat heart scan showed a score of 482--a tripling of his original score.

Obviously, major changes in Roy's program are going to be required to keep this rate of growth from continuing. But I tell Roy's story to illustrate the frightening power of diabetes to trigger coronary plaque growth.

Like Kryptonite to Superman (remember George Reeves crumbling and falling to his knees when the bad guys got a hold of some?), diabetes is the one thing I fear greatly when it comes to reducing your heart scan score. As you see with Roy's case, diabetes can be responsible for explosive plaque growth, more than anything else I know.

The best protection from diabetes is to never get it in the first place. (See my earlier Blog, "Diabetes is a choice you make".)
Is glycemic index irrelevant?

Is glycemic index irrelevant?



University of Toronto nutrition scientist, Dr. David Jenkins, was the first to quantify the phenomenon of "glycemic index," describing how much blood sugar increased over 90 minutes compared to glucose. The graph is from their 1981 study, The glycemic index of foods: a physiologic basis for carbohydrate exchange. The research originated with an effort to characterize carbohydrates for diabetics to gain better control over blood sugar.

Since Dr. Jenkins’ original work, thousands of clinical studies have been performed by others exploring this concept. The food industry has also devoted plenty of effort exploiting it (e.g., low-glycemic index noodles, low-glycemic index cereals, etc.).

Most Americans are now familiar with the concept of glycemic index. You likely know that table sugar has a high glycemic index (60), increasing blood sugar to a similar degree as white bread (glycemic index 71). Oatmeal (slow-cooked) has a lower glycemic index (48), since it increases blood sugar less than white bread.

A number of studies have shown that when low glycemic index foods replace high glycemic index foods (e.g., whole wheat bread in place of cupcakes), people are healthier: less diabetes, less heart attack, less high blood pressure. Books have been written about glycemic index, touting its benefits for health and weight control. Health-conscious people will try to substitute low-glycemic index foods for high-glycemic index foods.

So what’s not to like here?

There are several fundamental flaws with the notion that low-glycemic index foods are good for you:

1) Check your blood sugar after a low-glycemic index food like oatmeal. Most non-diabetic adults will show blood sugars in the 140 to 200 mg/dl range. The more central (visceral) fat you have, the higher the value will be. In other words, an apparently “healthy” whole grain food like oatmeal can generate extravagantly high blood sugars. Repeated high blood sugars of 125 mg/dl or greater after eating increase heart disease risk by 50%.

2) Foods like whole wheat pasta have a low glycemic index because the blood sugar effect over the usual 90 minutes is increased to a lesser degree. The problem is that it remains increased for an extended period of up to several hours. In other words, the blood sugar-increasing effect of pasta, even whole grain, is long and sustained.

3) Low-glycemic index foods trigger other abnormalities, such as small LDL particles, triglycerides, and c-reactive protein (a measure of inflammation). While they are not as bad as high-glycemic index foods, they are still quite potent triggers.

Low-glycemic index foods trigger the very same responses as high-glycemic index foods—they’re just less bad. But less bad does not equate to good. Low-glycemic index foods cause weight gain, trigger appetite, increase blood pressure, and lead to the patterns that cause heart disease.

High-glycemic index foods are bad for you. This includes foods made with white flour (bagels, white bread, pretzels). Low-glycemic foods (whole grain bread, whole wheat crackers, whole wheat pasta) are less bad for you—but they are not necessarily good.

Don’t be falsely reassured by foods because they are billed as “low-glycemic index.” View low-glycemic index foods as indulgences, something you might have once in a while, since a slice of whole grain bread is really not that different from a icing-covered cupcake.

    I was diagnosed a type 2 diabetic 30 years ago.  Now at age 70, I've lost 60 pounds through exercise and avoiding processed foods.  My breakfast every morning is boiled oats-groats and whole barley.  My vision is 20/20 and my A1C is always under 6%.  My diet is mostly vegetarian except for salmon or mackerel in my salad.  I usually avoid wheat products except when travelling or on social occasions.

    I don't disagree with your comments on GI in general, although as an Aussie I believe  it should be noted that Jennie Brand-Miller had a great deal to do with the develpment of the GI/GL concept.

    As a type 2 diabetic I used the concept in a slightly different way. I used peak post-prandial testing to develop my own personal database of the effect of various foods on my own blood glucose levwels. In effect, a personal GL list.

    My main reason for commenting was this: "Check your blood sugar after a low-glycemic index food like oatmeal. Most non-diabetic adults will show blood sugars in the 140 to 200 mg/dl range." Although I agree that oatmeal would do that to me - probably worse than 11mmol/L(200mg/dL) I have doubts that it would do that to a non-diabetic. In my experience testing friends and relatives I have never tested anyone who had levels that high after a meal who was not subsequently diagnosed as a type 2. The non-diabetics I have tested, regardless of the carb load of the meal (usually a feast like Christmas) have never reached 8(144), let alone higher numbers.

    I would be interested to know if you have seen numbers like that personally in your clinical experience in non-diabetics, apart from those affected by medications like Prednisone. Or was the statement based on the experience of others?

    This is one of the few published examples that I am aware of showing post-prandial blood glucose levels in non-diabetics:

  • Renfrew

    2/16/2010 12:37:19 PM |

    Good post.
    In the last few years there has been a better parameter, called "Glycemic load" (GL).
    While GI is always the same, independent of HOW MUCH you eat, GL takes into account "portion size".
    This is important because if you are eating half an apple or 2 apples it will have the same GI regardless, but not the same GL.

    The Mercola mixed diet recommends eating occasional higher glycemic foods AFTER the rest of a meal...since this apparently blunts the insulin response.

    I've been indulging in oatmeal...eaten dry as a snack.  Also fruit.  Shame on me.

    Also beans as part of meals...not recommended (like wheat as far the effect on the gut?).  Not to mention the salted nuts roasted in hydrogenated oils.

    Still have some work to do.....

    I buy food only every 3 weeks or so...and I find that when I run out of "favorites" near the end of this period and am eating only lean meats...assorted veggies...olive oil...spices...I feel better.  Though I do seem to get a major itch to go buy some "junk food"...plus a kind of panic as far as running out of food.  

    Wondering WHY this is...since I do feel better...do I have addictions?  Need to go to a clinic to recover? Wink

    I may be addicted to the sugar rush???  The oatmeal rush? The bean rush?  The hydrogenated oil/nut rush?  

    Dependent on my food reactions?

    Alan--

    Yes, I've seen many, many people with either "normal" (<100 mg/dl or 5.5 mmol/L) or slightly increased blood glucose (100-110 mg/dl or 5.5-6.0 mmol/L) with high postprandial glucoses.


    Peter--

    I believe there are a number of reasons, including the use of rice in place of wheat. Being part Japanese, I am well aware of their eating habits which are not as high-carb as often made out. There are confounding factors, as well, including iodine content of the diet.

    Also, there are indeed fat, diabetic Japanese people, also. Diabetes is, in fact, a growing problem in Japan.

  • whatsonthemenu

    2/16/2010 7:17:14 PM |

    Dr. Davis is right about the Japanese diet.  Northeast Asians eat a bowl of rice or noodles at every meal, but that is the only high GI food at the table.  A typical Japanese, Korean, or Chinese meal includes fish or meat and non-starch vegetables.

    Moreover, type II diabetes is common among middle-aged Asians, who get the disease at lower BMIs than non-Asians.  

    I am wondering about the accuracy of identifying whole grain products as low GI.  The Easy GL Diet Handbook lists a GI of 37 for whole wheat pasta compared to 43 for regular pasta.  Likewise, brown rice and long-grain white rice have nearly identical GIs of 55 and 56, respectively.  Low GI is defined at around 55 or less, so pasta qualifies as low GI, but the difference between whole grain and refined varieties is not significant, especially when GI is converted to GL.  As the good doctor notes, it's best to avoid grains altogether.

    30 Minutes after lunch (Portion of papaya, bowl of 'auyama' soup, half chicken breast with tomatoes and green peas, one boiled potato and salad with olive oil, one cup of lapsang tea): 111

    60 Minutes after lunch: 101

    Afternoon before eating some oats: 94

    30 Minutes after oats (quaker classics, soaked in water for 10 minutes with some almonds): 110

    60 Minutes after oats: 121

    30 Minutes after dinner (3/4 chicken breast same sauce as lunch, broccoli, salad, couple glasses of red wine): 109

    60 Minutes after dinner: 116

    90 Minutes after dinner: 92

    This opens many questions to me, like how much the time at which I had the oats affects. Or the fat I just had them with some almonds instead than as part of a whole meal

    Also as dinner seems to have more effect on my glucose than lunch even when lunch had  fruit and a potato I wonder if this is due to the black tea at lunch or to the time of the day.

    Also I wonder how much effect had the wine at dinner.

    I'll do some more tests when my fingers recover

    I would add to this post the fact that fructose has low GI, yet is more toxic and screws up the metabolism more than most other carbohydrates.  (E.g. causing fatty liver disease and insulin/leptin resistance; increasing hunger rather than satiating it.)  Food companies are motivated to add fructose to their products so they can claim a lower GI (hence the agave craze), but the fructose does more harm than most higher-GI carbs.

    I soon discovered that "low GI" foods, like oatmeal and other whole grains, still cause an unacceptable rise in my blood sugar.  Low GI may be a little better than high GI, but filtered cigarettes are a little better than non-filtered cigarettes.  Both are still bad.

    Glycemic load, which also takes into accout the number of carb grams, is much more relevant.  Non starchy veg, meat, & fat are about as low GI/GL as you can get.

    As for agave nectar, they still have to process it to extract it.  I'm not sure it's all that "natural."

    Low-glycemic index foods trigger the very same responses as high-glycemic index foods—they’re just less bad. But less bad does not equate to good. Low-glycemic index foods cause weight gain, trigger appetite, increase blood pressure, and lead to the patterns that cause heart disease.

    I eat oats with milk and 2 tbsp of ground flax seeds every morning, and since I'm doing that every morning I lost 10 pounds, and I feel great. I don't crave for sweet anymore. So, I don't understand how low glycemic foods like oats can increase your weight?
    Few of my friends who implemented oats and flax seed in their diet had similar results.
    No one mentioned very valuable fiber that oats contain.
