The problem with Obesity is you can't just go to a clinic for a few weeks or months to get clean. It is a complete lifestyle change that won't show really noticeable results for quite awhile. Even when others notice it, the overweight individual will not. I felt I needed to lose a little weight once... lost 10lbs and everyone was asking me if I lost weight and telling me I looked great. I didn't notice the loss, with the exception of those people telling me that I had, without me ever telling them I was working on it.
