Troy Garver describes what he calls the third law of thermodynamics for weight loss. Spending more energy than you consume should lead to weight loss. However, the matter is complicated by the fact that the body cuts its metabolic rate in response to calorie reduction.
In this podcast (download ipod compatible, 47MB), Troy Garver and I discuss something he calls the third law of thermodynamics in dieting. It's actually a contradiction because while you may believe that cutting calories (energy intake) will lead to weight loss, it frequently just does not. That's because the body is itself a dynamic system that tries to conserve energy as you cut intake.
After I mention to him what I like about the atkins diet: hunger remains after control and after induction energy is manageable if not bountiful, Troy mentions that "satiety" is one of the key factors he looks for when helping people manage their diets. He basically looks to give people foods from the groups they like but cleaned up, meaning without processed foods, and of course, reduced in calories.
We're going to switch topics in future podcasts. We have a strong man who is going to provide a couple of exercise analyses and some upcoming interviews with Paul Wright about his gym expansion plans.
