I agree that when it comes to portion size and whole foods, Europe makes it easy to follow by example. FWIW, I ate healthy in the US before because I rock climbed and needed to maintain a very lean mass. If I wanted to cut weight in Indonesia, it was easy: just eat their portion size, and I'd come in below maintenance.
What I've seen consistently amongst the non-healthy eating Americans is that they argue:
1. Dieting requires them to be hard on themselves and they're focusing on self-love, which they struggle with
2. They deserve a daily treat. They look forward to it, it brings meaning, etc
3. The taste of their food is super important to them, such that they can't imagine repetitively eating (meal-prep) or eating cleanly (no added sugar, monitoring sodium)
