Some people just don't want to let go of cherished myths that make them feel better -- this one is an example. My doctor is the one who gave me the data in talking me out of weight loss surgery. She's a very slender Asian lady.
Fat isn't unhealthy. Being sedentary and having a bad diet is unhealthy, but it remains as unhealthy for thin people as it is for fat people. Some thin people make themselves feel better with the illusion that they are "more in control than fat people" when they are, quite often, much less healthy.
Research shows (and my doctor has given me the stats, which I'd be happy to provide) that obesity definitely disables, it definitely irritates many conditions, but it is only correlative with diabetes and other conditions, it doesn't cause them. I'm fat and I'm not diabetic or hypertensive. I have low blood cholesterol levels. It may well be that what we've attributed to obesity has really been caused by dieting, which we fat people have done all our lives. I definitely am disabled by it, but that is a very different thing from longevity.
Medical evidence (the latest stuff) strongly shows that yoyo dieting is much less healthy than simply staying at a heavy weight. If your chances are 10% of succeeding at any diet (and that's what they are), then you're much better off resisting the diet wheel. And weight loss surgery kills people by the hundreds every year.
I've recommended two books for you - there are many others. If you want the current evidence and research, you'll seek them out. I don't ever go on in any debate on this issue, because fatophobes (and you don't sound like one, you're just misinformed) refuse to inform themselves, while I've been reading on this issue - from all sides - since childhood.
In a hundred years, medical science will feel terrible about how fat people were treated in the past. It'll be too late for us, but perhaps this new trend of discovery will benefit fat people in the future...if we're allowed to live outside of concentration camps. lol
I'm adding a few titles on here for those who genuinely want to inform themselves versus embracing the freeper mode of limited thinking, in example: "America's the greatest country because everyone knows American's the greatest country".
