Hey all doing a life overhaul

Hey everyone doing a life overhaul here. Just got out of the military and moved to so-california decided to focus on getting my self in the best shape of my life.....I feel healthy at 175-180lbs i am 6'1' and 25 years old. Currently I am 200lbs and sluggish. Been running and dieting with calorie counting. Also just recently started Insanity and loving it. Would like any and all pointers and could be a motivational buddy if needed. Thanks everyone.
