Introduction
GLP-1 medications like semaglutide (Wegovy) and tirzepatide (Mounjaro) are revolutionising weight loss, but they work best with smart nutrition. Appetite suppression from GLP-1s can lead to reduced calorie intake, risking nutrient gaps or muscle loss. Enter meal replacements (MR)—a simple way to support your GLP-1 journey. In this post, we'll dive into the evidence, benefits, and how Altralife's shakes, soups, and bars can optimise your results for sustainable health.
Understanding GLP-1 Therapy and Its Nutritional Challenges
GLP-1 receptor agonists mimic hormones to curb hunger, slow digestion, and boost insulin. They deliver 6-17% weight loss in non-diabetics, and 4-6% in those with diabetes, but side effects like nausea or low energy highlight the need for nutrition. Without balanced intake, users may lose lean muscle (up to 9.7% in some studies) or face deficiencies in protein, vitamins, and fibre.
The Evidence: Meal Replacements as GLP-1 Allies
Research shows combining meal replacements with GLP-1s enhances outcomes:
- Increased Weight Loss: Studies indicate 12% greater weight reduction when MR (1-3 meals/day) is added to GLP-1 therapy, thanks to structured calories and satiety.
- Preserving Muscle and Nutrients: High-protein MR reduces lean body mass loss while ensuring micronutrient needs are met, countering GLP-1's appetite effects.
- Clinical Guidelines: Experts recommend partial MR for GLP-1 users to improve adherence, metabolic health, and long-term success, per WHO and consensus statements.
This combination addresses GLP-1's impact on food cravings and intake, leading to better energy and fewer side effects.
