Well i'm 17 years old as of right now, but before i get onto problem let me give a little history.
6th grade, plain and simple i was fat.. 5'1 or somewhere around there at 125-130 pounds

7th grade fatter
8th grade 160 pounds 5'4/5
8th-9th grade 145 pounds
10th grade 122 pounds 5'8
I did cut diet 9-10 grade but i think with a growth spurt i just rapidly lost, i mean i was just losing a ton. But with that i was left with little muscle and flab.
10th grade i did track and it slimmed stomach down a bit but not much improvement.
11th grade i believe skin started to tighten up in this year otherwise i didn't see much.(did tennis this year)
12th grade year im accepted to college and ready to get this body in shape.
Today i am 5' 11 ~163
Mainly i've noticed a little more flab coming onto me and i don't understand chest is just annoying me i mean its just flabby but its all over the place sometimes it looks like no flab at all othertimes it seems to protrude more i look pretty in shape when im in clothing but otherwise i would never take off shirt and i havent felt comfortable with myself for the past 7 years.
If anyone can help please just help me i want to get rid of this flab and replace it with lean muscle, i don't want to bulk up and get big i want to maintain a slim figure with muscle and little fat.
I've been looking into jump roping > running because running bores me.
I could really use a diet that a school kid can follow.
And i would like to get down to 145 Healthily within 2-4 months if possible if not at least before may

PLEASE HELP
