Stop eating. I know that sounds sarcastic, but that is all i can say. I eat very little and still am chubby. I try to exercise when I can, which is not enough. Eating less, exercising more.
I am in the same boat. I am single and alone and getting older by the minute. I am very down right now, so I will stop talking.
If you are comfortable at your weight than that is great. You only have to be happy with yourself. I am not comfortable being overweight.
Dont lose weight for society, please yourself.
