I was 320 and an undiagnosed diabetic when I had a heart attack. Now my weight is good and my blood sugars are normal without medication. I'm in the 96th percentile for cardiac health for my age. It is hard so you have to keep at it, for the rest of your life. BTW, you probably won't lose vast amounts of weight by exercise alone. You have to change your eating habits permanently.

slvoid--I'm writing small because right now you're acting like a small person. You said that fat people have a problem because so many people mock them. Actually only a very small number of people are cruel enough to mock somebody with a problem. So I guess smart and 154 IQ are two different things, and acting like a pig has nothing to do with one's weight. You owe an apology.
