Men should exercise more. Playing basketball or something can not only slim down but also win the opposite sex. If you eat a lot, control your appetite. I suggest you take your time first.

For example, eat some milk, cereal, corn and bread in the morning.

I can be vegetarian at noon, as long as it's not too oily (I don't think I like snacks, and few men like them)

Leisure sports.

It is important not to eat staple food at night, or eat less. Some boys are in the same situation as you, but subtraction is scary, and they basically endure it at night, which is faster.

I wish you success in losing weight
