Today, we're diving into a topic that has the potential to revolutionize the way we think about weight loss and energy balance: the constrained model of energy expenditure, as proposed by evolutionary anthropologist Herman Pontzer.

If you're like most people, you've probably heard the old adage that weight loss is simply a matter of "calories in, calories out." This idea, known as the additive model, suggests that our bodies burn energy in a linear fashion, and that by either reducing our calorie intake or increasing our energy expenditure through exercise, we can create a calorie deficit and lose weight.

But what if this model is overly simplistic and doesn't actually reflect the complex realities of human physiology?

This episode peels back the layers of metabolism and physical activity, as we examine the startling notion that our bodies aim to maintain THE SAME LEVEL of energy output, no matter how much we move.

We'll explore why an uptick in exercise doesn't always translate to the expected calorie deficit and how our bodies compensate in surprising ways. Learn how to navigate this intricate dance of calories and master your physiological responses to achieve physical self-mastery.
