Best way to lose bodyfat?Diet or Exercise for Weight Loss?
November 25, 2006 09:36 AM
There has been a controversy over whether diet or exercise works best for weight loss. It has been a bit misguided, in my opinion, because it is caloric deficit or what I call negative energy balance that causes weight loss. I show this in my "Why We Get Fat" paper above under the Research link. Weight training exercise is the best way of all, but most weight trainers do not let themselves go into negative energy balance. This is because they are trying to add muscle mass. I think I may have convinced you that there is much that is wrong about theory and practice in body building, but the point applies with even more force when weight training is used to lose body fat.
Weight training that builds lean body mass when done in a manner that induces a negative energy balance is the superior way to lose fat and improve body composition. It is not a superior way to lose weight, but that is not the goal anyway. You do not lose as much weight because you build muscle, but you lose far more fat.
Improved insulin sensitivity, improved glucose clearance, and altered hormonal profile along with higher basal metabolic rate and improved exercise tolerance are the objectives of a weight loss program through weight training. And nothing works like Evolutionary Fitness in achieving those goals.
Here is one of the first studies to show that exercise is equally effective in weight loss and superior in hormonal action. Dr. Fontana, a member of the study team, was at the Caloric Deprivation conference where I also spoke. The clear goal of any exercise program is to induce negative energy balance and his protocol is the only one I know of that effectively does this in a well-designed experiment.
