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.

Built around the Score.
17 features. One number that tells you whether they’re working.
Six screens that do most of the work.
From the Muscle Guard Score on the home dashboard through the daily protocols, the body-composition check, and the visceral fat trend — the places your week actually lives.
Feed the plan.Not the guesswork.
Muscle Guard builds a 7-day plan from a curated GLP-1 recipe library. Every day hits your protein target within your carb and fat caps — if a day can’t reach protein, it nudges you to add a shake.
- 3, 4, or 5 meals a day — the 5-meal layout adds two snacks, common when appetite is small on a GLP-1.
- Swap any meal, regenerate any week — the planner rebalances your macros as you go.
- Deduped shopping list, one-tap PDF — grouped by aisle so a Sunday shop takes twenty minutes.

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.
