Where the Order Comes From
Google's ratings, as read
Ratings and review counts come from Google, read in October 2026, and we never edit them.
Right kind, right city
Only businesses Google files as weight loss services are listed, each with an address in Salt Lake City and a rating of 4.0 or higher. A company appears once.
Rating and volume together
The order weighs the rating by how many people gave it, so a long review history counts for more than a perfect score from a handful.
What each scorecard shows
Each scorecard shows the rating, the size of the review history, the share of four and five star ratings, 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 Utah medical or nursing board's public license search.
Questions for Your First Call
- Who prescribes or supervises the programme, and what licence do they hold?
- What does the whole programme cost, including follow-up visits, supplements or extras?
- What happens if I want to stop or pause partway through?
- How are side effects or problems handled between appointments?
