Key Insights Fatigue is a common but usually temporary side effect during the initial weeks or dose changes in GLP-1 therapy, caused largely by rapid calorie deficit, dehydration, and metabolic adjustments. Maintaining steady energy requires prioritising nutrient-dense meals rich in protein and complex carbohydrates, staying well hydrated, and managing electrolyte balance, which helps mitigate tiredness and supports overall metabolism. Gentle physical activity and good sleep hygiene are critical lifestyle adjustments that improve circulation, mood, and energy levels without overtaxing the body during the drug adaptation period.
