alt Hacker News> For the longest time people argued if overweight people ate too much or not.
Maybe uneducated people, but when was the last time anyone seriously doubted that excess calories make you fat? For serious people the discussion has always been about how to reduce the calories, because "just eat less" is provably ineffective. Simple minded people continuously suggest otherwise, but data really doesn't support their intuition at all.

It’s never been as black and white as you’re saying.
Lot’s of medical practitioners will even advise you that it’s the quality of food you eat, more so than the quantity. Look at all the published research around processed foods and ultra-processed foods.
Other nutritionists will advise you that obesity is all about your macros. And that if you want to lose weight you need to increase fat and protein intake and limit carbs.
Others have argued it’s less about diet and more about exercise and having an active lifestyle.
There’s also a bunch of research showing that poor sleep might cause obesity.
Ozempic seems to have thrown all that out the window and says that one just needs to eat less if one is overweight.

There's quite a few people here on this page.
Although part of the problem is poor word choice. Eating less absolutely works. Telling people to eat less absolutely doesn't work, because people won't do it (if they did do it, then it absolutely would work).
