Hormonal Obesity

Trans Fat and Coronary Disease – Hormonal Obesity XXXVI

Doesn't dietary fat 'clog up' the arteries and cause coronary disease?  It would seem from popular press that this has been proven beyond a shadow of a shadow of a doubt. Perhaps we had better take a closer look.  The Diet-Heart Hypothesis suggests that diets high in saturated fats lead to high cholesterol which leads...

The Diet-Heart Hypothesis – Hormonal Obesity XXXV

With the publication of Dr. Key's Seven Country Study, the origins of the Diet-Heart Hypothesis were laid down.  The major problem was that this was all observational data, and as such, was subject to severe interpretation.  There is nothing more dangerous in medicine than the correlation study.  It cannot be used to prove a hypothesis,...

Fat Phobia – Hormonal Obesity XXXIV

“It is now increasingly recognized that the low-fat campaign has been based on little scientific evidence and may have caused unintended health consequences” It has been over a decade since the influential Harvard researchers Drs. Frank Hu and Walter Willett wrote this in 2001.  Even now, the low fat campaigners are everywhere you care to...

The Deadly Effects of Fructose – Hormonal Obesity XXXI

For years, fructose was considered a benign sweetener because of its low glycemic index.  Fructose was found naturally in fruits.  The problem, as often is the case, is a matter of scale.  Whereas natural fruit consumption contributed only small amounts to the diet, added sweeteners, particularly in the form of sucrose or high-fructose corn syrup...

Sugar Sweetened Beverages – Hormonal Obesity XXX

The epidemiological evidence linking sugar consumption and diabetes as well as obesity is overwhelming.  Very little controversy surrounds this fact.  Another demonized food – salt, by contrast is far more controversial.  Many people argue that salt is not as bad as advertised – myself included.  But sugar, alas, has few defenders, only pushers.  This doesn’t...

Red Meat Dilemma 2 – Hormonal Obesity XXVII

Devotees of the low carb approach faced the red meat dilemma.  Meat was supposed to be non fattening because it was not a carbohydrate.  However, some large studies questioned this assumption.  The fascinating study “Changes in Diet and Lifestyle and Long- Term Weight Gain in Women and Men” demonstrated a rather large correlation between red...

Red Meat Dilemma – Hormonal Obesity XXVI

Our dilemma here is that there are really two opposing effects of meat and other animal proteins.  One is to raise insulin which tends to cause weight gain,  The other is to slow gastric emptying, increase satiety and tends to cause weight loss.  Which is the stronger effect? One of the largest association studies of...

Is Protein Fattening? – Hormonal Obesity XXV

The weight gaining potential of protein is a complex question.  Let me reiterate here that this area of research is still very new and we certainly do not have all the answers.  While refined carbohydrates (white flour) and sugar are almost universally considered fattening, there is maddening debate about the virtues or flaws of dietary...

Is Dairy Fattening? – Hormonal Obesity XXIV

Dairy proteins stimulate high levels on insulin due partially to the incretin effect.  Glucose, though does not seem to increase much.  If insulin increases, does this mean that dairy is fattening?  Here the answer is far more difficult. As we saw in our previous posts, protein containing foods may stimulate insulin partially due to the...

Insulin Index – Hormonal Obesity XXIII

Insulin levels had always been assumed to go up or down with the blood glucose levels which led to the glycemic index which had always been assumed to be a surrogate measure of insulin levels.  The glycemic index did not turn out to be as successful in weight control because glucose does not drive obesity....

The incretin effect – Hormonal Obesity XXII

What is the incretin effect?  With the Glycemic Index (GI), we had a physiologic scale for classifying carbohydrates.  Some raise blood sugars more than others.  When researchers looked at carbohydrate containing foods, there is a very close correlation between the GI and the amount of insulin released (Insulin Index - II). Insulin is the hormone...

Replace, don’t Add Fruit – Hormonal Obesity XXI

One of the greatest barriers to weight loss is conventional dietary advice to eat more to lose weight.  This was covered in a previous post "Time Dependence".  This advice sounds completely contradictory because it is.  Nevertheless, the media is full of unhelpful advice to eat more to lose weight.  The reason, I believe, is that...
