people have lost weight eating macdonalds everyday. Intermittent fasting is actually eating in a 4hr window period and not eating for at least 17 hours.
cravings go away, your body will adjust after two weeks or so. Your leptins(sp?) are what trigger hunger. Eventually your brain becomes satisfied with smaller meals, if you desire.
sugars and fats dont stay around long tjhey are the first to get burnt up. All the bodybuilders I know only eat in a 4hr window period, BUT they do say you HAVE to cheat once a week, or maybe more, in order to sustain your diet. If you dont reward yourself it makes it that much harder to stick to a stricter diet plan/
So you eat a few more sweets or some extra stuff, do some more exercise the next day and eat less and a little more healthy it will balance out.
