A few years after graduation, for unrelated reasons, I was on antidepressants. I massively over-ate, became obese, gained stretch marks that will likely remain for life.
There was no voice in my head telling me I was even over-eating, there was no awareness of what I was doing to myself even when I felt the weird tingle in my belly that in retrospect was the tearing flesh that has the outward sign of a stretch mark — I ate without thought.
There is no "natural, effective" solution, because our natural instincts are at odds with our unnatural world.
Seriously — the US and Europe have not been in a remotely "natural" condition since over a century before I was born. Even the air we breathe is significantly different from its natural condition.
Why do you think I gave that example?
Ozempic is exactly the type of drug Unilevel/Nestlé would create if they were tasked with reducing obesity. I wonder if they'll include a free 7 day dose of it with Mars bars.
That's pretty much the exact opposite of what you seem to think it does, and is exactly the kind of thing that will hurt Nestlé's junk food line. (Though probably not their bottled tap water line).
