I can't think of anything more distracting than trying to fit in 5 meals/day. Lost a lot of weight doing the slow carb diet, which is eating 4 times/day and the gradually shifted to the warrior diet, which is essentially one large meal/day. Takes a few days to adjust, but once I did my ability to focus has been unreal. Not everyday, but somedays I feel like I am on adderall and it is awesome. Anyways, just want to throw it out there, eating 5 times a day can be a lot for some, and I have found other hn'ers out there that practice one meal per day. I really really enjoy it.
