I am a 16 year old male. About a year ago, i decided that i was to heavy and needed to lost some weight. I slashed my calorie intake to less than half. On average i was consuming around 1000 calories a day. I lost weight rapidly and reached 150 pounds. My eating habits since then have been improved, slightly. I average 1500, to 2000. My main question is, did i cause any irreversible damage? Did i stunt my growth?( My current height is 5 ft 10 in.
