I don't understand, your body optimizes, and uses 20% less energy. However, you are still using the 80% which is more than not doing anything at all don't you?
Plus at least for running you can just run faster and make up for that 20% effioency gain. I personally do not think excercise is very good for losing weight but that particular argument is BS.
