what you say is totally true
what are the factors limiting the practical implementation of your solution?
Shouting at people that they are being stupid does not make them smarter, and does not always give them enough will power.

None. It's literally as simple as doing what you already know you should be doing. Why is this so complicated to understand?
Edit: will power fails because it implies that there's temptation. Temptation exists when you decide you want something you shouldn't. Just decide you don't want it. It is indeed the root of that.

so what is the reason why so many people are getting obese in the USA? Is this some moral (or other) weakness?
Discovering the correct reason(s) why for a situation enable the use of effective solutions for a problem.
This includes multiple contributing factors to any situation.
Attacking the wrong problem will lead to ineffective solutions.
Obesity is a complex problem with many contributing factors.
YES doing the right thing is important. But ignoring and not correctly identifying the contributing factors can hobble efforts to solve the situation.
Asserting that there are no relevant contributing factors is willful blindness.
I'm not going to play this game. Your point is 100% irrelevant because the true heart of the matter is "Don't eat more than you need." It really, truly is literally that simple. You can point at anything you want in advertising, food manufacturing, packaging or whatever else but at the end of the day it boils down to "Don't eat more than you need."
