Drop fat. Keep muscle.
Track what actually moves it.
Body recomposition is a slow, steady change in your body’s makeup — less fat, more muscle — at a roughly stable weight. Zabeau puts the three things that drive it in one app: your macros, your training, and your trend line.
What is body recomposition?
Body recomposition — “recomp” for short — means shifting your body’s makeup toward less fat and more muscle while your scale weight stays roughly the same. You’re not chasing a smaller number; you’re changing the ratio underneath it. Three habits drive it, and Zabeau is built to track all three.
Eat enough protein, daily
Protein gives your body the raw material to hold onto muscle while fat comes down. Hitting it every day is the single habit recomposition rests on.
Ask a little more over time
Adding reps, sets, or load as the weeks pass is the signal that tells your body to keep the muscle it has — and build a bit more.
The curve, not the morning
Scale weight swings daily with water and food. Recomposition shows up as a slow trend over weeks, so you watch the line, not the number.
Why is Zabeau built for recomposition?

Recomposition falls apart when your macros live in one app, your workouts in another, and your weight in a third. Nothing can see the whole picture, so nothing can tell you whether it’s working.
Zabeau keeps all three together. Set your calorie and protein targets and log meals in seconds. Run an editable routine and log your sets so you can see progression. Log your weight and read the smoothed trend line instead of reacting to daily noise. Every one of those is free.
Then the AI coach reads all three — your macros, your training, and your trend — and proposes specific, grounded changes you apply in one tap. It keeps you anchored on protein and progression, never shames you, and has guardrails against under-eating. See the full toolkit on the features page.
