From early August through October my kid started a 6 day week lifting program, took creatine and ate like it was job. He went from around 175 to 200. He is now at 194 and will probably lose a few more pounds as he is doing track (sprints, long jump and shot put) but he will get leaner as they will lift 4x week and run miles 5 to 6 days a week. He stopped creatine supplements in November when track started. He was trying for 4200 calories a day but is eating a lot more calories now
