A very specific, physiological condition where obesity is a result or side effect, despite moderate to heavy exercise and healthy diet habits/change? Sure, why not. That is, for actual obesity, not just that 15 extra pounds you want to lipo out of your gut for that Oscars-night dress. But to have some kind of "obesity is a disease/should be covered" blanket thing? No.

...I'm in general agreement with most of the others, where at least for the vast majority, being obese is not a disease. At best it could be classified as a psychological addiction to pleasure stimulus, with food instead of sixual stimuli, dope, or feeling rewarded while video gaming.

no, its not a disease. It a condition. Thats like saying missing limbs or what ever. being really fat is the effect, not its own cause. There are specific diseases that can make it hard for people to loose weight but those are separate conditions.

body fat is gained by eating more calories than you burn, end of story.

I have family members that blame all kinds of stuff like gmo's and "obese-o-genes" and so forth, and they talk about how they have diseases that make it so that burning calories doesn't cause them to loose weight. However those same people consider using a treadmill once and then never again to be "excercise", also specifically one relative I lived with would eat whole rotisserie chickens some nights but still blames gmo's.

I walked all my life and everywhere. Probably why I haven't been over 150lbs. Something for obese people to think about.

Just don't walk in the heat(yet). Take it in strides.

I know someone who jokes that "if I could lose 10 pounds by running on the treadmill for 10 hours straight, I could do that now and then, but having to exercise vigorously for an hour every single day just to lose a few pounds a week or near-starve myself/not eat any of my fave foods for months ... not so much." (she knows why she's fat, in other words, and doesn't blame it on her genes....).

Most people either vastly underestimate the amount of calories they're taking in on a daily/weekly basis, or are vastly overestimating the amount of calories they burn. Or the other trap I see people fall into a lot ... "I ran on the treadmill for 45 minutes today, so I'm going to eat that this huge frosted donut" - which pretty much negates running on that treadmill as far as losing weight goes.
