I think those making claims of eating disorders and glandular problems should supply some supporting data so we can determine what percentage of obese people we're actually talking about.
Indeed. I tried looking for information on it, but anything related to eating disorders is dominated by anorexia and bulimia.
I absolutely did not suggest this. I merely pointed out that there are medical conditions which can cause some people to be fat. I in no way suggested that all fat people suffer from these conditions.
Sure, but the point is that people always point that out whenever any mentions obesity, and it's completely irrelevant. Yes, there are medical conditions, but I have never seen any evidence presented to suggest that accounts for anything more than a tiny minority of obese and overweight people. There never seems to be any reason to bring it up at all other than to try to provide excuses for being fat that avoid any personal responsibility.
1) "discipline" around weight is universally a good thing and
Why would it not be a good thing? Being too fat or too thin is unhealthy. Being unfit, no matter what your weight, is unhealthy. Eating a poor diet, no matter what your weight or fitness, is unhealthy. Of course having some discipline and paying attention to what you put in your body and what you do with your body is a good thing. That doesn't mean being fat is necessarily bad, and if that's your choice then it's really none of my concern, but to argue that looking after yourself might not be a good idea is just plain weird.
2) that all fat people are only fat because they're lazy or greedy or ignorant. I have not even once seen an "except for eating-disordered people" disclaimer in a weight-related thread on this forum.
Well, firstly I have never seen anyone say that. Ever. If you can find somewhere here where anyone has claimed that all people are fat because they're lazy, feel free to show me. Secondly, the reason no-one bothers with a disclaimer is because, as I say in my reply to Arthwolipot, it's irrelevant. It's like complaining that people say things like everyone should walk to the shops to save on petrol without putting a disclaimer "except for those without any legs" on the end. No-one bothers with the disclaimer because the number of people it applies to is tiny, and it's extremely obvious to anyone with half a brain so there would be no point in saying it anyway.
What I am trying to say, in my clumsy way, is that any given fat person you meet could be like me, and that demonizing all fat people as lazy and self-indulgent is not helpful, original, or interesting.
Again with your "demonising all fat people" straw man. However, in case you forgot to the read the OP, we're not talking about specific individuals here, we're talking about a statistical fact about a large population. The fact that you may not be sure that a particular person you meet does not have a disorder has nothing to do with the fact that the vast majority of fat people do not.
Has there been a discussion I missed that was a little more thoughtful than "put the fork down"?
What exactly do you expect anyone to say? For the majority of fat people who do not have an eating disorder and simply eat too much, what else is there? Eat less and do more exercise. We'll stop saying that either when people start doing it.
What drives the average dude/dudette to gain weight in today's (presumably Westernized) society, where slenderness is next to godliness?
Are you going to accept the laziness answer here? People gain weight because eating high calorie fast food is generally easier, and often faster, than eating a sensible diet. They exercise less because it's generally easier and to not do exercise.
How do appetite and satiety work/how are they related/unrelated?
That's really more for the science forum. Basically, it all comes down to chemicals. If you eat lots, your body gets used to things and you have to eat more to get the same feeling of satiety. If you snack constantly you never reach the point of actually feeling full, and so end up eating a lot more than if you just have a few meals in a day. We still don't understand everything about appetite, but we do know quite a lot about it. I'd recommend starting a thread in the science section, since this certainly isn't my area of expertise.
How has becoming a "car culture" affected general activity levels of the population? Why don't people compensate with other activities?
What do you mean "compensate"? People didn't used to exercise for fun, they used to exercise because it was the only way they could get things done. Now that we can drive everywhere and have machines to do so many things for us, that is no longer the case. People don't compensate for the lack of exercise because they never wanted to exercise in the first place. They mostly still want to just get on with their lives without having to make too much effort.
What have been the historical advantages of overeating behavior/craving certain foods/etc, and how have they become disadvantages?
Again, that's more for the science forum, but it's a pretty easy question really. We evolved to eat particular foods as much as possible because that gave a higher chance of surviving when food became harder to find. A fat person can live longer without eating than a thin person. This has become a disadvantage because for most people in the West food, particularly high carbohydrate and fatty food, is no longer scarce.
For some reason, I just can't seem to will myself to start very often. It's more a matter of perpetual procrastination than actual laziness.
That seems to be pretty much the definition of laziness. I have exactly the same problem, but I don't pretend it's anything other than what it is.
Thank you for making my point for me. "It's their own damn fault", they'll get no sympathy from me certainly is the prevailing attitude.
Why should they get any sympathy? Whether its an active choice or simply the result of not paying enough attention to your diet and activity, becoming fat is something you do to yourself, it's not something you have done to you (and yes, that's obviously excluding people with a medical condition for those who need obvious disclaimers spelled out explicitly every time
