Ok. I know that there are a good number of people who are obese because they eat too much and don't exercise, but I can't stand this mentality that many seem to have that assumes that anyone who is obese is that way because of their own actions... even if that is true of a large percentage of people.
Some people have diabetes, are insulin resistant, or have a gluten allergy (and don't even know it). Any of those can royally screw with one's metabolism, making weight loss all but impossible without surgical intervention. I've even heard of people with brain tumors who are left with conditions that cause someone to never feel like they've had enough to eat. Not to mention, that, when a person gets to the point where they are obese, by then their stomach is stretched out, and the part of the stomach that stretches to hold excess food is the part that produces ghrelin, which is what sends hunger signals to the brain. So, for many, once they get to a certain point of excess weight, the odds of ever being a healthy weight again are less than 5% without medical intervention.
I'm not suggesting that everyone who is obese should run out and have surgery by any stretch of the imagination. That's a drastic step that should only be used when someone has tried every other option first, and seriously given those other options a serious effort. But I know many people whose lives have been saved by surgery, and many of those people had been fighting to lose the "old fashioned way" on their own for years.
Please let's not turn this thread into one of judging people for being obese. The whole point of the thread should be that Disney needs to find a way to prevent guests from being mad and embarrassed because they waited in line or wasted a fastpass, just to find out they can't ride.
