Plain-English Reference

Weight Loss & GLP-1 Glossary

153 terms from modern weight medicine, each explained in detail on its own page — the hormones, the medications, the trial names behind the headlines, the dosing vocabulary your doctor uses, and the insurance maze, minus the jargon. Written and reviewed against FDA prescribing information and primary trial publications.

How to use this glossary

Every entry opens as a full page: a plain-English definition, a detailed explanation of why the term matters for treatment, and related terms to keep reading. Start anywhere — the entries cross-link like a map. If you'd rather see the medicine than the vocabulary, our Wegovy, tirzepatide, and semaglutide tablets program pages apply all of it, and a free consultation turns reading into a plan. This glossary is educational — it isn't medical advice, and your own clinician outranks it on every question about you.

Every term here leads to the same next step: a free telehealth consultation where a licensed doctor applies it to your health history. Booking takes about two minutes — you're only charged after approval.
