Fat bias (and its detriment to the health of
2/3 of the population) in medicine is well researched and published about at this point.
There’s also a lot of published research about how “fat” people actually can’t lose weight as easily because of biological issues that prevent it, not because they can’t control themselves.
My 75yo aunt’s GP recently put her on an addiction / weight loss medication that has had her drop over 30 lbs in 4 months. Unbeknownst to any of her children (or me, I’m as close) until she started telling us how much weight she was losing — and we asked HOW? I asked her what had been advised alongside to prevent muscle loss and bone density loss given her age, and especially as a woman, the answer was absolutely nothing.
There’s a lot of foolish stuff out there and plenty of under-informed people with degrees.
But again, this is a food site. It’s a particularly odd place to have toxic (and well-debunked) diet tropes keep popping up.
