I never thought about a medical problem before I think I will have to check this out. Someone also told me I could exercise yet I may not get too skinny which this person is right. So others who have my problem when they do not eat too much and yet are still big need to check with a doctor to make sure it is not a medical problem and just keep exercising even if you do not get into the size 8 to 0 that the world seem to love right now. Enjoy the body your in and to the .com world let us give others a chance just because they are big does not mean they overeat, let us stop thinking that person is gross, and instead take time to get to know them. You may find a friend if you just took time to look deeper within. For not all can be model thin.
