you ingest under 500 Kcals a day?
man you are asking for trouble, even though I don\'t know you bf% I can guess that you lean body mass will probably be in the area of 140-150 lbs, and with that amount of kcals, your at least 400 kcals below your maintness level. And to throw in the fact that you\'re active, your body must be going in to a catabolic state...eating muscle.
you may have lost some weight, and got results, but it\'s very unhealthy. Personally I would never recommend anything below 1000 kcals for an adult male. But then again, it\'s your body.
