>>8 The combination will help, yes, as it will burn a few extra calories. Exercise alone can not do much. I assume by "binge" dieting you mean crash dieting, and yes, encouraging generally good habits > deprivation is important. But research is showing that taking your diets slow isn't as good for you physically as we think, so crash dieting may be the way to go in the long run. It's just a matter of ensuring people are in the right mental state to do so and are being monitored by doctors.
"How bad do depressions and anxiety has to be before they 'legally' acknowledge that you can't work?" For the few mental illnesses that are recognized for disability, it's handled on a case-by-case basis. You're observed and tested for a period of time to see whether or not you can handle day to day tasks, as well as the tasks you'd be expected to perform in the industries you worked in before their onset. The same goes for physical disabilities.
Coming from a US perspective^: You're almost always rejected the first time(s) and need further testing; it's very, very difficult to get approved. Being suspicious of anyone on disability here (can't talk for Scotland) is incredibly silly with how impossible it is to get approved.
"A few binge eating here and there doesn't make you morbidly obese." Except that it literally can. Weight doesn't magically go away once you gain it unless you under-eat or over-exercise after, and it gets harder to lose what you gain every time you do so. It only takes a little bit of binging to gain a significant amount once you've crossed that threshold.
"before you talk about ignorance (how American)" Do you have a problem with the existence of legitimate vocabulary? Sometimes people just aren't aware of these things, whether it's because of their environment or the only recent discovery of said information. There's nothing bad about bringing that up as a point of interest to explain someone's behavior or struggle with a topic.
"As exampled in the article, canned food and no veggies." While the sodium in canned food causes water retention, it's not innately bad for you. What you eat is less relevant to weight loss than the amount of it. Not sure what your point is here. Yes, the women in the article given here are off-kilter, but I don't feel they make the overarching topic any less legitimate of a discussion.
"Don't spoil people who have given up on life is what I think." Don't be jealous of people who are struggling in ways you can't understand getting assistance is what I think. It's sad and pathetic to watch people who are capable of taking care of themselves finding offense in others being assisted. Just know that if you have a time of need, society'll be around to help; in the mean time, be grateful you have the freedom to assume everyone has the same emotional or physical capacity that you do.
