This is not the proper conclusion. He also started regular resistance training. I would say one of the biggest problems is seeing weight loss as either being nutrition or fitness, when it should ALWAYS be seen as a combination. Why? Because the goal is usually to lose fat. Without muscle stimulus, the body will include muscle in the weight loss. Muscle tissue is important long term for metabolism and other health aspects.
