Tiredness is reported by some people on GLP-1 medications, often linked to eating less than the body needs. General information on nutrition, fluids, sleep, activity, and when to ask your provider about lab work.
GLP-1 medications reduce appetite. When intake falls below what the body needs — particularly protein and fluids — energy can drop. Changes in eating patterns, sleep, and activity during treatment can add to that.
Fatigue that persists despite adequate intake, or that comes with other symptoms, is a reason to speak with your provider so other causes can be considered.
General habits that many people find helpful. Your provider or a dietitian can give guidance specific to you.
Eggs, poultry, fish, dairy, legumes, or a protein shake when appetite is low. Regular protein intake supports muscle during weight change.
Several small meals rather than one or two large ones, with complex carbohydrates such as oats or sweet potato for steadier energy.
Dehydration is a common and easily missed contributor to tiredness.
Seven to nine hours of sleep, light daily activity such as a walk, rest days when needed, and limiting caffeine late in the day.
Many people eat less than they realise once appetite falls.
If fatigue persists despite adequate intake, sleep, and activity, your provider can consider other causes.
