Another spin on the 80/20 rule, says Dr. Lipman: stopping eating when you're 80% full. That means slowing down and checking in periodically throughout the meal about what your body is saying. Does the food no longer taste great? Are you getting that "I don't really need any more feeling"? Thinking 80/20 as you eat can help slow you down and be more mindful. Being in tune with your body prevents overeating, he says.
In the book Triumph Over Disease, Jack Goldstein, DPM, outlines his true story in overcoming ulcerative colitis by sticking to strict water fasting and a vegetarian diet. Goldstein is one of very few people who has tested his own tongue scrapings, urine, feces, even perspiration during a water fast, Strychacz says. "He found that the contents [during a fast] are different than normal -- that toxins like DDT do get removed."
