There are a few recent threads about people hitting plateaus or wanting to lose weight. In an article I read about yesterday (more about IF and leaning out) someone tried this tactic. If total calories required to lose weight is 1500 (ie should be calorie deficit) instead of having 1500 a day he would have 2000 one day and 1000 the next. You wind up with the same calories but the higher meal day keeps metabolism revved up. I suppose this is similar to the alternate day fasting idea but interesting to see another take on it.
