I don't mean to be overly harsh, but saying "just changing their diet" is quite ignorant. There's been a huge amount of research into the challenges of weight loss, so it should be (more) common knowledge by now that it's not just about deciding to do it and "having discipline" - it takes much more than that, both physically and psychologically. I understand where you're coming from, though, I used to think the same - I remember a specific situation where an obese person next to me was breathing heavily from doing something easy and me thinking "how do you hear yourself breathing audibly from doing almost nothing and not decide and just change it". Unfortunately, I got into a situation where I now understand the issue and am struggling to lose weight, despite hearing myself breathing audibly after picking up something from the floor and all the rational understanding and knowledge of what I need to do. IMO, in a lot of cases, the first step should be going to a therapist.
