It's well known that people treat fat people worse; I constantly wonder how aware people are of their own biases?
For what it's worth I've been fat before and I've been in shape before. I have my own biases that are beyond the scope of this comment. Never taken one of these drugs but only because of cost/access; I'm actually curious to experience them. If they work for people, I say they should take them.
As for exercise, it has many benefits but is a fairly minor contributor to weight loss. I am doing a bit of a hardcore diet at the moment (helped a ozempic competitor), lost 20kg/44lbs in 3 months, and I noticed no difference in change in weight whether I do 1h of exercise bike daily (max resistance) or whether I do a week without.
Because apparently a surprising number of people can't calculate bodyweight doses.
But if there's a way to lose weight without major lifestyle change, it threatens that tidy moral barometer. Someone might look virtuous without actually being so. Cognitive dissonance ensues. So they hope and wish for anything to catch out and punish these "cheaters."
Because humans spent some hundred thousand years on earth with no fat human in sight, and only around 3-400 with the ultra obese. It's unnatural.
Cars, computers, and cellphones are unnatural. If you can get over those, you can get over recoiling in atavistic horror from people who don't meet your beauty standards.
They are not a part of, or the whole human body
It's easy, substitute the obese with the smokers demographic. Imagine them whining that they smoke because it's an environmental issue, that they just can't do otherwise, that it's a metabolic issue and not a willpower one, a genetic thing, lack of access to alternatives... anything besides their own will.
I wonder how taking a medicine for the rest of your life is a win-win when there are places in the world where obesity is almost non existent and it's been proven to be largely lifestyle related. Besides, semaglutide just makes the subjects crave less, reinforcing the willpower role in weight loss.
I have read people in this forum state that if they eat less, they gain more weight for some unknown genetical issue, like thermodynamics do not apply to them.
You have to keep a clear head as an early adopter in some things, and be aware of incentives. Remember, the pharma company pushing the drug/treatment to market is out to make money first. Having a knock-on problem down the line to fix also serves that purpose, and in fact, has been a tactic employed by other notorious pharma manufacturers. Lest we forget the lessons of the opioid crisis do quickly.
There are win-win tradeoffs. Vitamins, for instance. If you're running a vitamin deficiency, there isn't a downside to increasing your intake of that vitamin. (Curing acute dehydration via IV is another shortcut that just works.)
The Ozempic story, for me, has been more about how we almost seem to be reflexively against the idea of a win-win. A lot of people want there to be a tragic downside to the drug for reasons that aren't entirely clear to me.
