There is a difference between the big belly with fats which is the results because of extra fat all over the body and the other belly that you will find the guy completely thin but he got that one big as a watermelon ...

The last one is because of the wall of the tummy getting week because of lack of exercising and the insides are pushing out and while it's weak, they keep pushing creating a pressure there that goes bigger the more your insides pushes your tummy wall.

The other one, you need to have a diet and exercise as well to burn that fat. Some of them got that big, but when you punch him there it is really solid.

In the end it does not matter while you can enjoy your life and be happy ... Forget about wearing suits to cover it up or carrying a bag and put it in front of you ... It is either you leave it or just work hard on it to lose it ...

Do not dwell in the past, do not dream of the future, concentrate the mind on the present moment. (Gautama Buddha)
