Gary Taubes has become an expert on the obesity epidemic. During his initial research he discovered that there were poor malnourished populations all over the world that were experiencing increased levels of obesity. Another interesting part of the equation is that many of these populations that were consuming less food/calories were also working jobs with intense manual labor. This was completely contrary to the old "exercise more and eat less," "calorie in versus calorie out" diet theories.
This peaked his interest and led to a career dedicated to understanding and battling this widely misunderstood epidemic. Here are the highlights from his discoveries:
1) When insulin is secreted or chronically elevated, fat accumulates in the fat tissue. When insulin levels drop, fat escapes from the fat tissue and the fat deposit shrinks.
2) We secrete insulin primarily in response to the types of carbohydrates in our diet. The wrong carbohydrates are driving insulin, which is driving fat.
3) Avoid bread and everything else made with flower, cereals, pudding, and all other white root vegetable. Also avoid sugar and sweets. These are the carbohydrates that drive insulin which drives fat.
4) Eat plenty of: Meat, fish, birds, all green vegetables, eggs, cheese, fruit (limit bananas and grapes).
The bottom line is this: Obesity is a disorder of fat accumulation, not energy balance (not overeating or sedentary behavior). Fat accumulation is regulated fundamentally by insulin and dietary carbohydrates. The only non-pharmaceutical remedy is to restrict or remove the causative agent, i.e., the wrong carbohydrates.
The simple truth appears to be, that if we remove the foods from our diet that drive insulin, that drive fat, we might be able to skip the under-utilized gym membership next January.
