14 year old boy? Weight 130 kg? Height 173? Seek ways to lose weight and keep fit.
You are all right in height and weight, and you are not fat at all. Stacking several layers is not a sign of being fat. Real fat people don't fold their bellies. If you feel a lot of fat, you can eat less at night, then walk for 40 minutes or walk for 40 minutes, and you can see the effect in about half a month. In addition, if you feel hungry at night, you can make some cereal to drink, just the original taste.
