I agree if someone is unhealthy we shouldn't praise them. They should be open to help and it should be looked at the same as addiction (drug, alcohol, etc.)
I think the biggest problem with overweight is what is healthy or unhealthy. To my knowledge, there is no good measurement that can clearly indicate overweight as BMI and other measurements all have their issues (obviously not talking about those clearly overweight).
I take pride in the fact I am currently in the position of being one of those people who breaks BMI. Technically overweight with a 12% body fat. Weight is an irrelevant number to what you see in the mirror.
I think the biggest issue is that people don't like to admit that they are in need of help, they want to look like they have the situation under control but that is in most cases false.
Very true, and other instances they are aware of the issue and just don't care.
