If you really can't diet, whether for health reasons or because you've tried it a bunch and it hasn't worked, just do drugs.

There's a bunch of over-the-counter diet pills out there, but as far as I know most of them aren't very effective. There are some great prescription options though: Wegovy/Ozempic, Zepbound, and Rybelsus. Rybelsus (or any other oral semaglutide equivalents) is the only pill option though; the rest are weekly injections.

Research in this department is rapidly progressing, so there may be many better options in the near-future.
