I have investigated various Intermittent Fasting styles including ESE, Warrior Diet, Fast 5 and leangains. The science seems to make sense, so I've chosen the leangains approach, basically a 16 hour fast and 8 hour feeding window (sometimes more like 18/6). I have previously tried the more common 5-6 small meals, but since I enjoy eating big meals, I was never really satisfied with 6 small meals. IF seems to fit my life style. I have lost some fat, my strength has not suffered and I have plenty of energy. I train early a.m. in a fasted state. I do use protein shakes to get enough protein and plan to begin using BCAAs before and after training.
