There are heavy people and there are skinny people.
My Brother has a set of twins you can realy see the differnce in the 2 one takes after her mother very thing almost to thin. Just going into the first grade she is about 65 pounds (guess) Then there is the other she takes after her father my side of the family she is big for her age heavy i'd say pushing little over 80 pounds. They both eat likes birds very health councouse.

That is a fair bit of it. The heavy one will never be the thin ones size. Geniticly it just is not going to happen. It is not fair but that is the fact of life.

I have been heavy all my life. Geneticly I am large but I also have a monky on my back. I like to eat and I eat out of bordome. But even if I did not. I will never be skinny. There is no going back once you are heavy. You can lose wight and be healthy, but but your not going to get to that goal of 6,1 170 male adonis. When you are large things chang to support the wight bones get bigger muscle builds up and so on.

I could go on the strictus diet in the world and I have but I will never be porn star thin. It is not in my geans or my slacks either.
