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...

Sugars 1 – Hormonal Obesity XXIX

Sugars are fattening.  Of that, there is really little doubt.  Almost everybody can agree upon this fact.  The reason it is fattening is a little more contentious.  Some consider sugar as empty calories since they contain few essential nutrients.  Others think that sugar makes food more 'palatable' and thus cause us to overeat these foods....

The Benefits of Vinegar – Hormonal Obesity XXVIII

Diluted vinegar is a traditional tonic for weight loss.  Indeed, mention of this remedy is found as far back as 1825, when Brillat-Savarin wrote about its dangers.  A British poet, Lord Byron had popularized the weight loss tonic and would reportedly go for days eating biscuits and potatoes soaked in vinegar.  Popular ways to use the vinegar...

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...

The Genetics of Obesity – The Epiphenomenon of Obesity II

One commonly overlooked aspect of obesity is its genetic underpinnings.  Obesity tends to run in families.  Obese parents have obese children.  Obese patients often have obese siblings.  Yet most conventional theories of obesity do not account for these genetic effects.  Start here for Hormonal Obesity. For example, in the erroneous Caloric Reduction as Primary theory,...

Prevention of Resistance – Hormonal Obesity XII

One of the keys to high insulin levels lies in insulin resistance.  To start the Hormonal Obesity series – click here. Insulin resistance leads to high insulin levels.  It also appears that high levels of insulin also leads to insulin resistance in a vicious cycle.  How does the body normally defends against insulin resistance? High...
