@Mickeyy 214,
Exercise!!!
Get out and run, swim, play sports when you can.Eating healthy is the hardest part for me XP but try to get fruits and vegetables into your diet a lot!
Cut back on things like ice cream, soda, chips, or any other sugary/greasy foods.Diet sodas are perfectly alright.
Llimit yourself to about one a day.Don't eat LESS! eat HEALTHIER! eating less will actually make you fatter, but don't eat TOO MUCH either!!!
Besides, unless your OBESE I don't think you should worry about your weight your body's still growing things could change.
