Kelly LeVeque explains how protein triggers satiety by regulating hunger hormones like ghrelin, the "gorilla hormone." Gut nerves detect amino acids and signal the body that nutritional needs are met, creating a calm state and preventing the blood-sugar crashes that come with high-carb meals.
When we are eating enough protein, we feel satisfied. We are regulating hunger hormones like ghrelin, which I call the gorilla hormone, and neuropeptide Y. There's now dozens of hunger hormones screaming at us to eat. And what's interesting is we have nerves that innervate our gut that are searching for essential amino acids, and they're searching for fatty acids. And our body feels calm and relaxed when we're getting what we need. And that makes sense if you think about it. Like, I need amino acids to survive, then there's going to be mechanisms that are searching for— it's checks and balances that those are arriving in your body and you're able to heal, perform at your best, stay balanced, build muscle mass, and feel energized. So I love protein. I think it's made an amazing comeback, but it doesn't have a spike and crash in the same way as carbohydrates.
