What other solution do you propose?

(Yes, eating healthy and exercising would probably help most people, but many remain)

Progress on making fecal transplants more widespread, less wide-spectrum antibiotics prescriptions and more targeted ones (it would help with antibiotics resistance, as a nice side-effect), investing more in bacteriophages as an alternative to antibiotics, and far stronger limits to chemical pollution, and cleaning up existing ones.

Eating healthy and exercising.

And for the remainder: go to your physician to get to a state where you can do healthy diet and exercise.

For the small part that remains is highly suggest getting an actual physician to give you treatment options, instead of self medicating with sketchy Chinese chemicals.

That's what GLP-1s do: they make it trivial to eat healthily.

If you want to be reductive, and correct, these medicines make it trivial to manage total food intake.
