Dieting is 70% of being healthy brother. I weighed 172 lbs when I was 14, 15-16 i weighed 205. Eating right with the right kind of weight training and cardio is all you need.
I am on a lean diet atm.
Liquid egg whites in the morning
10 am- almonds
1pm- A piece of chicken and a fat free yogurt
4pm- peanut butter sandwich
Dinner- chicken and vegetables.
Idk if your parents will buy u chicken breast all the time, you could subsitute it with turkey (no bread) you could also try cottage cheese or string cheese if you do not have yogurt.
I lost 13 lbs in 3 weeks with this diet and exercising I am still doing the diet but I cheat at dinner time sometime lol Ive lost enough weight, im just trying to maintain now
