Eating less is not that hard

There are always hundreds of excuses, but hardly any of them are reasonable.

but blaming everything on external factors is addict behavior.

Okay, I 'll give it a go too. Even though @storksforlegs@beehaw.org already mentioned what I am about to say, obviously to no effect.

You say you are speaking from experience. That you 've lost some weight. And then you make claims that go way beyond your experience, that are far tοo general. I won't go so far as to say that the position you support is ignorant. This won't be nice. I will assume you are more educated than I am. But I will point out, that your experience alone hardly constitutes solid ground to speak for everyone. There is room there for you to be mistaken.

Addictive behavior is not rational. People get addicted to stuff, whether there are inherent addictive qualities to whatever they get addicted to or not, not because they choose so, but because they are vulnerable to addictive behavior. This, more often than not, is something indicating other psychological issues that need to be addressed. It can be insane amounts of stress, it can be depression, it can be many other issues that need to be addressed in order for someone with addictive behavior to get to a place where that person no longer needs crutches to function. Attacking how an addict rationalizes the addiction, not only doesn't address the issues that lead to this behavior but it probably adds to to them.

So, since you can't know why someone is displaying addictive behavior, implying, for example, that a person with severe anxiety that turns to food for comfort is lazy, is actually neither nice nor helpful. It's not even speaking the truth as you said. It's just negative, probably adding to the problem causing the unhealthy relationship with food.

I won't bother with the rest of the generalizations you 've already made, but I will suggest this. If you want others to respect your experience when you speak about it, try to consider its limitations before you draw assumptions that include other people's lives.
