It's easy to say "just diet ez" and it's hard to "just diet".

If you can administer a treatment as a simple one and done thing, that's alright. If it's a pill you got to take every day, that's pretty bad. More than once a day? Horrible. Why? Because a lot of patients just don't have it in them to take a pill 3 times a day consistently.

If it's purely an "exercise willpower" thing or a "change your lifestyle" thing? You might as well give up.

The medical establishment wants to do things that work. Telling people "go diet" doesn't work. Semaglutide, evidently, does.
