Everyone's brain hates it when they lose weight. It doesn't matter your starting point. You could start from a point where you are athletic versus someone who's not athletic, couch potato phenotype. The moment you lose a little bit of weight, we're talking even a few pounds. I'm not even talking, you're talking about a stone. Even if you lost five pounds, what happens in your brain is your brain is used to you carrying, you or me carrying a certain amount of weight. The moment your weight starts to go down as an adult, it goes, this is a big flag comes up. This is reducing my chance of survival. This is what the brain thinks. And so what it does is it begins to use strategies, not conscious, nothing to do with our brain, anything like that, to drag us back up, kicking and screaming to where we were before. First of all, it makes us hungry. And second, it actually very, very secretively lowers your metabolism ever so slightly. Even eating exactly the same thing, you are now storing more than you're burning. Even eating exactly the same thing. Part of the strategy to get you back up to where you were before. So once you were on that keto diet, and we can debate, talk about how it works and whether it's useful, but once you're on the diet, your weight goes off, you're able to keep it, but you said, man, I can't do this. And so you stop. And the moment you stop, your brain goes, comes back on and starts dragging you back up. This is going to be true for pretty much every single diet that is out there. The moment you stop the diet, the weight will come back on.
