@Kro @DA70D6 @matrix @maxim Well yeah, you aren't supposed to feed your kid on cheetos and oreos
What I meant is that past 25 your metabolism changes. I didn't go above ~80kg until turning 26 regardless of how much I ate. Now I'm around 90kg, way more muscle, but also need to work out a bit to not develop a belly. Still eat like a beast though, and couldn't go above 100 unless I started to chug pure grease.
The US is absolutely irrational in regards to food, I won't argue it. I like that they have proper portions when you eat out and even if you tend to eat a lot you won't need to order three plates, but a lot of people there don't stop when they've hit their body's needs.
