If you want to lose weight, watch what fat people eat and then don't eat that.
I used to work with a lot of Chinese people. They had the same kind of life the rest of us did, sendentary, sitting at a desk most of the week. Not a single one was fat. I think it was their diet, lots of veggies, rice, and not a lot of fried stuff.
But Fat people eat everything!
But they eat everything! (Just kidding)
