>Humans are well known for compensatory eating True, but this applies to fasting as well as exercising (if not more so)! At the end of the day, what matters most for fat loss is changing your habits. I don't think that "calories in / calories out" has been invalidated, so you have two sets of habits you can adjust. If it is easier for you to reduce calories in with fasting vs. portion control, then go for it. IME it is incredibly painful to miss a meal, but not so painful to eat less calories when I do eat - particularly if I substitute high density carbs (bread, pasta, sugar) for lower density (veg, etc). I do think that just focusing on calories out is problematic for the obese and/or long term sedentary - mainly because they are way more likely to injure themselves by not ramping up to activity very carefully...
