A short YouTube monologue by Jim Katsoulis arguing that human bodies and brains evolved for food scarcity, so they instinctively encourage eating and resist weight loss. He recommends reframing weight loss as a process of personal development—becoming the person you want to be—because the brain is more receptive to identity-driven change than to the idea of losing weight itself.

Your body doesn't want you to lose weight. Actually, neither does your brain. We've evolved over millions of years in a food scarce environment, so that now when you see food, your body and brain are encouraging to eat as much of it as possible because your body and brain still think you're in that food scarce environment and that's going to help you survive better. So when you want to lose weight, the first thing you have to do is reframe this process from one of that's primarily about losing weight to one that's more about becoming the person who you want to be. You need to wrap your weight loss and personal development because your brain wants you to become a better version of yourself, but it does not want to lose weight.
