For starters...this guy is a complete...who doesn't have a clue what he's talkign about.

Let's start with his first obvious error...It is the GLYCEMIC INDEX, not the hypoglycemic index. Hypoglycemia is what happens when you eat foods too high on the Glycemic Index.

Yet, "There is no compelling evidence that in normal individuals day-to-day fluctuations of the blood glucose level are an important determinant of how much food is consumed," University of Washington endocrinologist Michael Schwartz told me. But "Although the concept that insulin triggers weight gain has little scientific merit," he wrote earlier in the journal Science, "it remains a key selling point for advocates of diets that are low in carbohydrate and high in protein and fat."
|
"no compelling evidence"...I guess that would depend on what he defines as "normal." Those who are insulin resistant [which I believe is actually a good majority of the US Population] must not be included in his definition "normal individuals." Now that he's excluded most of the population, whose he counting as "normal" ??? The small percentage of folks who can eat their body weight in carbs and not gain an ounce ??? I hate to tell ya Fumento, but those folks ain't normal by any stretch.

And because the South Beach diet is indeed low-carb, Agatston feels compelled to claim that, "When we eat fats, we become satiated." False. The literature on this is both voluminous and clear. Fat and carbohydrates reduce hunger equally, although protein may have a slight edge.
|
It's official, Fumento's smoking some good shit...I'll make him an offer...Prove me wrong. I've eaten [on a few occassions] up to 1,200g of Carbohydrates in a day. If fat and carbs both satiate equally, then by his logic...he should be able to eat 14 sticks of Butter no problem. I'd like to see him try it.
Now, back to reality...on Atkins, I eat up to 200g of fat and 300g of Protein. Normally, my fat is closer to 100g and Protein to 150g. This even blows his theory about Protein being more satiative out of the water...Otherwise, my Protein intake would be lower than my fat intake. Also, how is it that I feel full at between 100 and 200g of Fat...yet can easily eat an entire box of Graham Crackers (which are Whole Grain IIRC)...with up to 400-800g of Carbs IN ONE SITTING ???

Were either the hyperinsulinemia or fat-satiety theories true, it would certainly show up in the decades of studies comparing diets of varying fat and carbohydrate content. It does not. For example, in April 2001 the Journal of the American Dietetic Association reviewed "all (such) studies identified," over 200 total. Conclusion: "Weight loss is independent of diet composition."
|
Uh...you might want to take a closer look at some of those studies...'cause a number of them show the exact opposite: that folks who eat a diet in low in carbs and high in fat are more easily satiated.

Most recently, a review in the April 9, 2003, Journal of the American Medical Association found "insufficient evidence to conclude that lower-carbohydrate content is independently associated with greater weight loss compared with higher-carbohydrate content."

Kekwick, A., Pawan, G.L.S., "Calorie Intake in Relation to Body-Weight Changes in the Obese," The Lancet, July 28, 1956, pages 155-161.
In one study, 3 groups took in the same number of calories. One group was fed a diet of 90% Carbs, another 90% Protein, and a third 90% Fat. The 90% Carbs group on average gained weight, while the 90% Protein group lost weight...But, the 90% Fat group lost the most weight.
In a second study, two groups were fed diets of either 2,000 Calories Low-Fat or 2,600 Calories Hi-Fat. The Low-Fat group gained weight, while the Hi-Fat [and presumably Low-Carb] group lost weight.
Young, C.M., Scanlan, S.S., Im, H.S., et al., "Effect on Body Composition and Other Paramters in Obese Young Men of Carbohydrate Level of Reduction Diet," The American Journal of Clinical Nutrition, 24, 1971, pages 290-296.
In one study, 3 groups took in the same number of calories, at varying levels of Carbs. Fat weight change corresponded inversely to carb intake. I.E. The less carbs eaten, the more fat lost, the more carbs eaten, the less fat lost.
There's a number of other studies...But, typing 'em all up would take forever.

In fairness, the South Beach diet is superior to Atkins in two ways. First, it encourages the consumption of healthier unsaturated fats, while saturated fats like lard and those in bacon are emblematic of Atkins.
|
Did he even read the book ??? Bacon is discouraged. While Lard is technically allowed, yain't gonna be able to find allowable [non-hydrogenated] Lard in most Grochery Stores...and as a result very few Atkins Dieters use Lard. Also, he seems to forget Beef [and Lard] are a majority Unsaturated...While they have a decent amount of Saturated Fat...The levels of Palmitic and Myristic Acid [the only two Saturated Fats that have been proven to raise LDL considerably] are exceeded considerably by the levels of Stearic Acid and Oleic Acid, both of which are known to Lower LDL and possibly raise HDL.

Second, while the South Beach diet allows carbohydrates, it promotes higher-fiber ones. Fiber is good for overall health. Further, by adding non-caloric bulk to food, it can aid weight control. But South Beach still can't be called a high-fiber diet since it discourages carbohydrate consumption.

Obviously, he does NOT get the concept of NET Carbs.

Ultimately neither regimen favors permanent weight-loss, which is why both authors fall back on anecdotes without having published a single study supporting their diets.
|
"A single study" ??? If he really believes that, he seriously needs his head examined. While I can't speak for SBD, Atkins has shown dozens of studies that back up his WOL. More and more studies are coming out every day that show Atkins works...I'm reminded of the time Atkins gave a speech and asked the audience: "How many of you could do this for life ???" Then, he asked how many could eat Low-Fat/Low-Calorie for the rest of their life...We all know what the results were...A number of folks indicated they could do Atkins for Life, while almost none believed they could starve themselves for life. Oh and BTW, the USDA Diet has done so well at generating permanent weight loss in Americans...Heavy Sarcasm intended, as if you couldn't tell.

Obesity experts who do publish such studies, including those directly comparing Atkins dieters to high-carb dieters, say Atkins works only because it excludes so much of what we normally consume that we end up eating fewer calories. But soon people get bored and repack the pounds. A 12-month study in the May 22, 2003, New England Journal of Medicine showed as much.
|
There was a recent study that showed Atkins Dieters eat more, yet lose more than those on a Low-Calorie/Low-Fat Diet. in fact, a number of studies...including those I previously mentioned showed that persons eating a LC/HF Diet, lost more weight than those eating a LF/HC Diet, even when consuming significantly more Calories.
Water is stored with Glycogen [and possibly fat, though I am not sure on that part.] Obviously, any person on a Ketogenic Diet will lose alot of water in their first week. By my estimates [using weight/measurments/etc...] I lost over 2 pounds of fat and over 2 pounds of lean weight my first week in induction. My second week I lost just as much fat, but little to no lean weight...After that, I continued to lose significant amounts of fat. Admittedly, I lost 2 pounds of water [or more] my first week. But, I also lost an equal amount of fat. I have continued to lose fat, and the majority of my weight loss has been fat, not water, muscle, bone, or whatever non-fat part of my body du jeur the LF Advocates claim I'm losing.

If you do lose fat with South Beach it's because you're following the recipes (comprising two-thirds of the book), which amount to a low-calorie diet. But the spontaneously eating Omnivorous Americanus will not stick to recipes for very long.
|
My understanding of SBD is that it is realatively low in Calories. But, assuming it is truly low in carbs...that would not be the only reason folks lose. Otherwise, they would not lose faster than LF Dieters on comparable caloric intakes.

That's why, although the subtitle of Agatston's book modestly calls it "foolproof," a whole chapter is devoted to why people fail on it.
|
Any good diet book should have such a chapter. It is possible to fail at any diet...The reasons, not the least of which include not following it properly. Atkins speaks of Carb Creep in his part on those who fail...He also considers the possibility of medicine or a sluggish thyroid being the cause. None of these are the diet's fault...yet, if he's chosen to leave that portion of his book out...many of those who plateau or experience carb creep...would quit and tell everyone that Atkins doesn't work, rather than finding out what was really causing them to fail.
