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.--“Quick Wits” are short mini-episodes between full episodes to give you an actionable strategy or hit of motivation.These mini-episodes give you practical advice on fitness, training, and mindset based on my everyday experience with clients that you can implement right away.If you enjoy these bonus episodes or have feedback on how to make them better, just send me a message on IG @witsandweights or hit me up in the free Wits & Weights Facebook community.Support the show📱 Get Fitness Lab - Philip’s science-based AI app for fat loss, muscle building, and strength training for people over 40.
