I think you hit the nail on the head there. People are fat because they are lazy, plain and simple. My parents are overweight because of years of being over worked trying to raise my sister and I. They didn’t have much time for themselves to exercise or make healthy meals. As a result they have gained weight for about 15 - 20 years and my sister and I were both overweight also. I met my wife when I was 16 and she helped me change my eating habits and I lost 20 lbs without working out. I just cut out the fast food, pop, pizza, ice cream, etc. for a few months and I felt and looked much better. I have decided that for the rest of my life I will make sure that I exercise and eat smart so that I can be a good role model for my kids. This obesity being contagous is pure BS and was probably determined by a bunch of fat scientists who need a reason why they got fat.
