Agree...
I was up to 209lbs, (im down to 189 now, lost 20 pounds through nutrition control, running, and working out).
Its really the simpler things that will really help you out. Eg: Dont drink that coke with your food, dont get the side of fries, dont eat desert.
And if one just consiously listens to when the body feels sated, one eats much less.
I dont necessarily reccomend running to overweight people though. Its quite rough on the knees, especially if youre overweight.
Try swimming, or cross trainer machines, or cycling! Theyll all get your weight down.
Incidentally, my dad has diabetes, and the doc assures him, that if he would only lose 20 pounds, it may even go away!
