Sometimes it has to do with disease. Thyroid diseases can cause people with the best of efforts to become obese. I think of myself and my illness also. When I weighed in at the ER almost 3 years ago, I was right at 260 pounds. After being diagnosed with cancer and starting treatment, I dropped down to 170 within a year. I am now right around 200 pounds, which is about right for a 6'1" guy.

There are a lot of things that can sway one's weight dramatically one way or the other.
