Track your GLP-1 Journey.Protect yourMuscle.
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 substantially — across every GLP-1 South Africans actually take, including compounded semaglutide and tirzepatide.
Built for: Compounded semaglutide and tirzepatide, plus Ozempic,
Wegovy, Mounjaro, Zepbound, Rybelsus, Saxenda and Trulicity.
GLP-1 medications work. The question is what you’re losing.
Every weight-loss number on the scale hides a second number — the one your doctor isn’t asking about.
of every kilo lost on a GLP-1 can be lean muscle — not fat. Strength gone. Posture gone. Metabolism slower than before you started.
With adequate protein (1.2–1.6 g/kg/day) plus resistance training 2–4× a week. Muscle preserved. Fat lost. Result intact.

How muscle preservation works on a GLP-1
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.
Phase-3 trial body-composition data, structured-intervention arms. Sources cited in the cornerstone.

What to expect from Ozempic, Wegovy, Mounjaro, Zepbound, Rybelsus, and Saxenda — week by week, dose by dose. Nausea, fatigue, GI symptoms, and when to call your doctor.
Do you lose muscle on a GLP-1? What the research shows.
Without intervention, 25 to 40 percent of weight lost on a GLP-1 can be lean muscle, not fat. With adequate protein and resistance training, that figure drops substantially. The cited evidence, in plain English.
