Hello. I am having. Fat belly. And my weight is 80.Age. 25 please help me?

Can't.. If you are a 25 year old male who weighs 80 pounds - you are either terrifically short or terrifically underweight. I really can't encourage you to lose any more fat or any more weight. Severe undernourishment can sometimes result in death. If you are not already in treatment for your issues with your body & youf health - please seek this out. Best wishes.
Fat beely. Okay firstly - exercise daily. Secondly - stop or cut back on carbohydrates, fatty foods, fizzy sweet drinks. East lots of protein, vegetables and fruit(non sweet).
