How This List Is Built
Numbers straight from Google
Ratings and review counts are read straight from Google in October 2026. We never edit them.
Right kind, right city
Only businesses Google files as weight loss services, with an address in San Antonio and a rating of 4.0 or higher, are considered. Each company appears once.
Rating weighed by volume
A big review history counts for more than a perfect score from a handful of people. That's why a 5.0 can sit below a 4.7.
Starting pool
Beside each write-up, a scorecard gives the rating, the review count set against the other listings we started from, and whether Google lists a website, phone and hours.
Check the license
Prescription weight loss medicines can only be prescribed by a licensed clinician. Before you book, ask who prescribes at the clinic, then look that person up on the Texas medical or nursing board's public license search.
Before You Book, Ask
- Who prescribes, and what is their licence?
- What will a visit and any follow-up cost in total, including medication and pharmacy fees?
- What happens if I want to stop or pause?
- How are side effects handled, and who do I call?
- Will you keep my own doctor informed?
