About GLP-1 Protein Calculator

Our mission is to help adults using GLP-1 therapy understand a transparent protein-planning framework, its assumptions, and the questions they may wish to discuss with a clinician or registered dietitian.

Why We Exist

GLP-1 medicines are prescribed for different conditions, and weight change can include changes in fat mass and lean body mass. In a DEXA substudy of STEP 1, semaglutide 2.4 mg plus lifestyle intervention was associated with reductions in total fat mass, regional visceral fat mass, and total lean body mass. The study does not establish an individual protein prescription or predict a person’s body-composition change. Source: STEP 1 body-composition analysis.

This calculator shows a transparent 1.2–1.6 g/kg educational planning range for many adults using GLP-1 therapy. Protein intake is one factor commonly considered alongside overall intake, activity, strength training, medical history, treatment tolerance, and clinician guidance. The tool does not diagnose inadequate intake, assess body composition, or promise a health outcome.

Ownership & Editorial Boundary

GLP-1 Protein Hub is owned and operated by Vibelity Inc., an independent tool publisher. The site does not represent its owner as a physician, dietitian, nutritionist, patient expert, or product tester. It publishes the calculator's method, sources, limitations, and correction process so visitors can assess the tool's educational scope.

Calculator Method

The calculator uses disclosed inputs such as body size, activity, strength-training pattern, meal pattern, treatment phase, and a higher-BMI adjustment to explain its planning logic. Dietary Reference Intakes are population reference values for healthy people, and the NIH notes that individual requirements may be higher or lower. This tool provides general educational information, not an individualized clinical nutrition plan. Source: NIH Office of Dietary Supplements.
