The evolutionary science behind why you can’t lose weight and how to avoid 5 modern food mistakes | Prof Daniel Lieberman

تفصیل

Why can’t you lose weight, and why do modern diets fail? Today, Harvard professor Daniel Lieberman explains how evolution shapes hunger, body fat, food cravings, and modern food mistakes. You will learn why eating well can feel so hard in today’s food world. Using themes from Daniel’s new book, Fed Up: What Evolution Reveals about Food, Diet and Eating Well, we explore how our modern food environment explains weight gain, failed diets, and confusion about what to eat. We discuss calorie counting, ultra-processed food, hunger, and why there may be no single “best” diet for everyone. By the end of the episode, you’ll have some simple ways to make better food choices and will know how to make healthy choices easier. If your body evolved for a world where food was scarce, what does that mean for how you eat today? 🌱 Try our science-backed and tasty wholefood supplement Daily30 🌿Let your gut microbes snack on the ZOE Gut Health Bar Build healthy habits.
