We have a bit of a discussion on this general theme ("Gap-1 inhibitors in healthy people for weight loss) here: Intermittent (oral) Rybelsus / Semaglutide use in healthy individuals?
I’ve had significant weight loss when using metformin, and also the SGLT-1 inhibitors (Canagliflozin and empagliflozin) and would recommend that approach also for quick weight loss with minimal side effects. I quickly (2 to 4 weeks) lost about 15lbs with metformin (and it stayed off after I stopped taking it), and another 10lbs with the initiation of canagliflozin (in about 2 weeks). So, another potential approach you might try. I will also be taking empagliflozin for the long term for health benefits.
