Effects of Dietary Supplements on Muscle Mass and Function While Using GLP-1 Medication

This pilot study will examine whether daily protein supplementation with or without a mixture of culinary spices can help preserve muscle mass and function in adults who are using GLP-1 medications for weight management. The study will include 75 adults who recently started a GLP-1 medication and are experiencing weight loss. Participants will be randomly assigned to one of three groups: standard of care, protein supplementation plus placebo capsules, or protein supplementation plus mixed spice capsules. The study will last 6 months. Researchers will compare changes in muscle mass and muscle function among the groups. Muscle mass will be measured using DEXA and D3-creatine enrichment. Muscle function will be assessed using walking, stair-climbing, and grip-strength tests. The study will also evaluate metabolic and inflammatory markers, body composition, dietary intake, physical activity, fatigue, sleep quality, quality of life, and other measures related to muscle health.
