On a GLP-1, appetite drops — and three things slip first: protein (which protects muscle), and fiber and water (which keep a slowed-down gut moving). This turns published ranges into three daily targets to aim for, plus realistic ideas for low-appetite days. It’s a ballpark for thinking, not a prescription.
Why ranges, not exact numbers? Needs scale with body size, training, and how fast you’re losing weight — and for higher body weights, clinicians and dietitians often base the protein target on an adjusted or goal weight rather than current weight. Treat these as starting points and confirm what’s right for you with a clinician or registered dietitian. The science and sources are on the protein evidence page.
