- **GLP-1** — GLP-1 (glucagon-like peptide-1) is a gut hormone released after eating that stimulates insulin, slows gastric emptying, and reduces appetite. (https://elevateglp.com/glossary/glp-1)
- **GLP-1 receptor agonist** — A GLP-1 receptor agonist is a medication that binds the GLP-1 receptor to reduce appetite, slow gastric emptying, and improve blood sugar control. (https://elevateglp.com/glossary/glp-1-receptor-agonist)
- **GIP** — GIP is a second incretin hormone that works alongside GLP-1 to regulate insulin, fat handling, and appetite. (https://elevateglp.com/glossary/gip)
- **Semaglutide** — Semaglutide is a GLP-1 receptor agonist sold as Ozempic and Rybelsus for type 2 diabetes and as Wegovy for chronic weight management. (https://elevateglp.com/glossary/semaglutide)
- **Tirzepatide** — Tirzepatide is a dual GIP/GLP-1 receptor agonist sold as Mounjaro for type 2 diabetes and Zepbound for chronic weight management. (https://elevateglp.com/glossary/tirzepatide)
- **Gastric emptying** — Gastric emptying is the rate at which food leaves the stomach; GLP-1 medications slow it, which extends fullness and can cause nausea or bloating. (https://elevateglp.com/glossary/gastric-emptying)
- **Lean mass** — Lean mass is body weight that is not fat — mostly muscle, bone, and water — and 25–40% of GLP-1 weight loss can come from it without protein and training. (https://elevateglp.com/glossary/lean-mass)
- **Sarcopenia** — Sarcopenia is the progressive loss of skeletal muscle mass and strength, which rapid weight loss can accelerate. (https://elevateglp.com/glossary/sarcopenia)
- **Protein** — Protein is the macronutrient that preserves muscle during weight loss; GLP-1 users should target 0.7–1.0 g per pound of goal body weight daily. (https://elevateglp.com/glossary/protein)
- **Electrolytes** — Electrolytes are minerals — mainly sodium, potassium, and magnesium — that regulate fluid balance, nerve signalling, and muscle contraction. (https://elevateglp.com/glossary/electrolytes)
- **Magnesium glycinate** — Magnesium glycinate is a highly absorbable, gentle form of magnesium used for sleep, muscle relaxation, and cramp prevention. (https://elevateglp.com/glossary/magnesium-glycinate)
- **Soluble fiber** — Soluble fiber dissolves in water to form a gel that softens stool and slows digestion, making it the preferred fiber type for GLP-1 constipation. (https://elevateglp.com/glossary/soluble-fiber)
- **Constipation** — Constipation on a GLP-1 is caused by slower gut transit, lower food volume, and reduced fluid intake rather than by the drug damaging the bowel. (https://elevateglp.com/glossary/constipation)
- **Nausea** — Nausea is the most common GLP-1 side effect, peaking 24–72 hours after a dose and usually easing within two to four weeks at each dose level. (https://elevateglp.com/glossary/nausea)
- **Telogen effluvium** — Telogen effluvium is temporary diffuse hair shedding triggered by rapid weight loss, low protein, or nutrient shortfalls — not by GLP-1 drugs directly. (https://elevateglp.com/glossary/telogen-effluvium)
- **Titration** — Titration is the scheduled stepping-up of a GLP-1 dose over weeks or months to improve tolerance. (https://elevateglp.com/glossary/titration)
- **Weight-loss plateau** — A plateau is four or more weeks without weight change, driven by a lower metabolic rate, muscle loss, or unmeasured intake creep. (https://elevateglp.com/glossary/weight-loss-plateau)
- **Gut microbiome** — The gut microbiome is the community of bacteria in the digestive tract that influences digestion, immunity, and GLP-1 production. (https://elevateglp.com/glossary/gut-microbiome)
- **Dehydration** — Dehydration is common on GLP-1 medications because appetite suppression also blunts thirst signalling. (https://elevateglp.com/glossary/dehydration)
- **Whey protein** — Whey protein is a fast-digesting complete dairy protein with a high leucine content, making it efficient for preserving muscle on low food volume. (https://elevateglp.com/glossary/whey-protein)
