GLP-1 medications burn fat. Without intervention, 25 to 40 percent of what you lose can be lean muscle, not fat. Muscle Guard tracks the protein-and-training playbook that drops that figure below 10 percent — across every GLP-1 South Africans actually take, including compounded semaglutide and tirzepatide.

Muscle Guard tracks the playbook for you, on every approved GLP-1.
Nine features, all working together. Lead with the differentiator — track every drug, every metric, every milestone.
The hero metric. Combines protein adherence, resistance training, weight trend and body composition into one number that captures fat-loss-without-muscle-loss.
Delete your account in one tap, all data is gone. No cookie banner. No third-party trackers. POPIA, GDPR and CCPA-ready by architecture, not retrofitted.
Knows the standard titration schedule for every approved GLP-1 — including Rybelsus oral pill and compounded vials.
Snap your meal — get macros, protein target progress, and a quick logging interface. Powered by Open Food Facts + Google Gemini, transparently disclosed.
Pattern detection across symptoms, mood and logs. Spots stalls, side-effect clusters and protein gaps before they derail your journey — and surfaces a specific next move.
A branded one-page report your prescriber can read in 60 seconds. Hand it over instead of 12 weeks of WhatsApp screenshots.
Built-in pose guide, side-by-side compare, monthly reminders. Comparable photos that tell the truth.
Waist, hip, neck, body-fat estimate, visceral-fat rating. The numbers that prove muscle is being preserved while fat is lost.
Built for the emotional reality of a GLP-1 journey. Not "lost 1 kg" — milestones that respect the work.

The mechanism, the prevention plan, and the studies that ground both.
GLP-1 receptor agonists suppress appetite and slow gastric emptying so effectively that most users enter a sustained calorie and protein deficit. Without adequate protein intake and a resistance-training stimulus, the body mobilises both fat and muscle for energy — producing the lean-mass-loss share that shows up consistently in body-composition substudies of the major trials.
The prevention plan is well-established: 1.2 to 1.6 g of protein per kg of body weight per day, resistance training 2 to 4 times per week, avoid extreme calorie restriction, and track strength and body composition — not just weight.
Muscle Guard is built around that plan. Every feature, every milestone, every metric is in service of one thing: fat loss without muscle loss.
