The Obesity Code: Unlocking the Secrets of Weight Loss (Why Intermittent Fasting Is the Key to Controlling Your Weight)

by Jason Fung

HERE’S THE QUESTION that has always bothered me: Why are there doctors who are fat? Accepted as authorities in human physiology, doctors should be true experts on the causes and treatments of obesity.

The key assumption of the theory that reducing caloric intake leads to weight loss is false, since decreased caloric intake inevitably leads to decreased caloric expenditure.

You cannot make up for dietary indiscretions by increasing exercise. You can’t outrun a poor diet.

OBESITY IS NOT caused by an excess of calories, but instead by a body set weight that is too high because of a hormonal imbalance in the body.

Highly refined carbohydrates are the most notorious foods for raising blood sugars. High blood sugars lead to high insulin levels. High insulin levels lead to weight gain and obesity.

Insulin resistance requires persistently high levels.

The government is subsidizing, with our own tax dollars, the very foods that are making us obese. Obesity is effectively the result of government policy.

Once inside the body, only the liver can metabolize fructose.

The bottom line is that excess fructose is changed into fat in the liver. High levels of fructose will cause fatty liver.

Soluble fiber reduces carbohydrate absorption, which in turn reduces blood glucose and insulin levels.
