Contributor(s):Author: Dr Richard MackarnessDr. Richard Mackarness book exposed the calorie fallacy and proposed a non-carbohydrate Stone Age diet of protein and fat with no restriction as to the amount eaten. OBESITY IS always fatiguing and always a great strain on the body. It is not due to greed but, as Dr. Mackarness so clearly explains in this book, to a little-understood difficulty in the economy of the body which makes it turn sugars and starches into fat instead of promptly using them to give energy, as do the people who remain normal in weight.
