Dietary Fat and Hyperinsulinemia

I've often recommended switching to a diet higher in natural fats and lower in refined carbohydrates. What's the deal with dietary fat? Simply put, dietary fat does not raise insulin. And hyperinsulinemia is the main driver of obesity. Hyperinsulinemia means literally, high insulin in the blood (hyper means high, and -emia means blood levels). So,...

Nutritionism’s Great Blunder

Dr. Ancel Keys has been accused of many great nutritional crimes, but his greatest blunder was the inadvertent triumph of nutritionism.  Dr. Keys was one of the great proponents of saturated fat as one of the main determinants of the epidemic of coronary disease in the 1950’s and 1960’s.  This led directly to the low...

The MultiFactorial Nature of Obesity – How to Lose Weight II

The multifactorial nature of obesity is the crucial missing link. There is no one single cause of obesity. Do calories cause obesity? Yes, partially. Do carbohydrates cause obesity? Yes, partially. Does fiber protect us from obesity? Yes, partially. Does insulin resistance cause obesity?   Yes, partially. Does sugar cause obesity? Yes, partially. All these factors converge...

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...

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 Atkins Decline – Hormonal Obesity Part XX

The Atkins revolution was well and truly underway by the mid 2000s.  Millions of people around the world were following the Low-Carbohydrate lifestyle.  Burger King introduced lettuce wrapped burgers to reduce the carb content.  Everybody seemed to know somebody who was on the diet and had lost a lot of weight.  The possibility of permanently...

The Atkins Revolution – Hormonal Obesity part XIX

Short term studies of the Atkins low carbohydrate diet were very encouraging.  Not only were patients losing more weight, but their metabolic profiles were improved compared to the low fat diets of years past.  Millions of people were taking a low carbohydrate lifestyle, and seeming to enjoy the benefits.  By the mid 2000's, Dr. Atkins...

The Atkins Onslaught – Hormonal Obesity XVIII

The low carbohydrate diet long preceded the infamous Dr. Atkins.  Jean Anthelme Brillat-Savarin (1755 -1826) wrote the influential textbook “The Physiology of Taste” in 1825. Sometimes considered the father of the low carbohydrate diet, he wrote: “The second of the chief causes of obesity is the floury and starchy substances which man makes the prime...

The Role of Fibre II – Hormonal Obesity XVII

The main role of fibre is that of an anti-nutrient.  By various mechanisms such as bulking and viscosity the absorption of nutrient may be slowed in the GI tract.  This is especially beneficial in the absorption of glucose which tends to cause insulin to spike with meals.  This study illustrates the effect of fibre. Thirteen...

The Role of Fibre I – Hormonal Obesity XVI

Fibre is the non digestible part of food, usually a carbohydrate that our bodies cannot break down and absorb.  They pass through our system largely unchanged.  There are 2 types of fiber - soluble and insoluble based on whether it can be dissolved in water.  Plant foods often contain varying amounts of both types of...
