"Fasting is, after all, a scientific method of purifying the body, and should be done scientifically. In my opinion, 60-70% of the so-called "healthy" people of today, and 85 to 95% of the seriously ill people would die from the effects of loosening the tremendous toxic poison they have stored in their bodies, if they tried a long fast, say of 21-35 days." Paul Bragg N.D., PhD; page 55 of "The Miracle Of Fasting"
"One cannot simply rely on how much body fat a person has to decide on how long to fast that person. Even obese individuals can develop signs of starvation while still overweight if their muscle reserves fall to dangerously low levels while their fat reserves are still adequate.....Cardiac failure could occur in patients who no longer have skeletal muscle reserve and who continue to fast." Joel Fuhrman M.D.; page 210 of "Fasting and Eating For Health"
Fasting should be taken seriously. It absolutely should not be entered into with the attitude of "if I don't eat for a couple of weeks, then I'll lose a lot of weight and my life will be better". I'm sorry these warnings are taken to be negative thinking. But I cannot in good conscience recommend anyone jump into a prolonged, unsupervised fast with little or no preparation just to lose a few pounds. On the other hand, with patience, preparation and a proper attitude fasting is a great method to employ as part of an overall health plan including safely losing weight.
