When our family is overweight, we're 40% more likely to be overweight. But when our friends are overweight, we're 170% more likely to be overweight. And that's when you think about children, right? Children. All they want is their parents approval. Hey mom, hey dad, watch me, watch me, watch me, watch me, right? And they have no inhibitions in the outside world. They don't care what the world thinks about them at all. I'm dressed like a princess, I'm going to dress like Spider man. But I want mom and dad to watch me jump off the steps. And I would desperately want mom and dad's approval, right? And that's where all of the learning about what's appropriate, what's inappropriate comes from, strictly from our parents. Nothing else. Until they reach about adolescence, we convert to only needing our parents approval, to only needing our friends approval. Frustrating for the parents, but very, very important for social animals because what we're doing is acculturating outside of our families, beyond our families, into the broader tribe, and that lasts for the rest of our lives.
