Prior to 1945, European physicians knew that obesity was a direct result of eating too many carbohydrates and sugars.

But by the 1970s, the American medical establishment convinced the world that the problem was total calories.

Therefore, the answer to obesity was semi-starvation diets.

The problem with this program was that obese people ate no more in terms of total calories than people with normal fat composition.

When I first examined the problem, I was puzzled as to why “experts” used total calories as the most important measure of a healthy diet. People were told to count calories from proteins, carbohydrates, and fats as the same.

I tried to convince people that calories from protein and fat did not contribute to obesity, and that the only important calories to count were those from carbohydrates and sugars.

But no one would listen.
