What's going on with my weight?

The problem is your body no longer uses that food to grow, for example grow your muscles, your height etc.... so what it does now is stores that food as fatty deposits therefore the more you eat the bigger you get. i had exactly the same problem as you. went to the docter they said i should eating to much.... i cut down and now im back to 175 pounds. theres no point in visiting the doctor because they'll say exactly the same to you
