> And you know what it is? It's volume. I eat too much.

100% this.

I lived in Asia for a few years and obesity is rare (though increasing for youth). It's not like they get more exercise (most people don't) or eat healthy (it's mostly carbs), but 100% portion sizes.

I see people who work manual labor jobs eat lunch that is a bowl of noddles, a few thin slices of chicken or pork, and a few veggies. I highly doubt it exceeds 500 kcalories. It's probably half the portion size you'd get in the US.

Mystery solved. If you're only eating 1500 to 1800 kcal per day as an adult male doing manual labor, it's pretty obvious why you're at 10% body fat.
