I'm 45, and I still drink regularly, and when I'm hungover, I'm pretty sure a regular delivery pizza still sounds orders of magnitude better than a gas station pizza.
As Derka has referenced, I think people struggle to understand just how addicting sugar is, and how sugar is in ALL of our fucking food, often unnecessarily but just as a way to sell more fucking food. This is why I think food addiction is a real thing, because sugar addiction is a real fucking thing. Generative AI, so grain of salt, but:
Now, in America we pour sugar into fucking everything. Specifically, Corn Syrup, which we basically created to be an additional government subsidy for farmers. I've been on and off Keto for a few years now, and the side result is that you look at all the labels. The amount of "Added sugars" in the columns for foods like fucking bread, or condiments, snacks, and sometimes even processed meats, is staggering. And that's before you get to sugary drinks, even "healthy" ones like Gatorade. We lace everything with sugar, to make it more addicting, and then ignorant parents feed this shit to their children from day one. My son has a friend who's parents are overweight. The kid is still a rail, but he won't be, and he's gobbling down just koolaid and candy and ice cream and pizza and such at all times. I think his relationship with food might have never had a chance. And it's worse for poor children, where their access to food is limited to processed, sugar addicting shit.
For many people, and in many regards, being fat is a choice. Maybe for all people, on some level, it's a choice. It's also a choice for me to climb Mt. Everest. Technically, I can do it. But realistically, I'm going to fucking die. And I say that as a 45 year old, reasonably in shape person, who probably needs to drop 15-20 lbs and quit drinking the way I drink.
