I can see how this would make sense, but for people who are living a sedentary lifestyle and are only moderately overweight, I find it hard to believe that exercise is a bad idea, even if it were to somewhat slow their weight loss progress (and this is without getting into "weight" loss vs. fat loss, which is what really matters)
