Recompose for Mounjaro
Recompose is a UK app for people taking Mounjaro (tirzepatide), a weekly GLP-1 injection. It works out which day of your shot week you are on and changes what it asks of you accordingly (a protein target, meals that suit your appetite that day, and a resistance session scaled to your energy) with the aim of helping you hold on to muscle while you lose weight. It costs £9.99 a month, and you can see your own week free without an account.
The problem with using a normal tracking app on Mounjaro
Calorie apps assume every day is the same. On a weekly injection they are not. In the first days after your shot your appetite may be almost gone; by the end of the week it is back with force. An app that asks the same thing of you on both days is asking the wrong thing on at least one of them.
What Recompose does instead
- Knows where you are in the week. Tell it your injection day once, and every screen after that is written for the day you are actually on. See the cycle engine.
- Protects protein on the worst days. A floor rather than a target, with low-volume options you can face. See protein and food.
- Puts the hard session where the energy is. Resistance work scheduled for your return days, optional on suppression days. See workouts.
- Shows you what you kept, not just what you lost. A weekly check-in that tracks strength alongside weight. See the weekly check-in.
- Reminds you about the shot. The evening before and the morning of. See reminders.
What a week on Mounjaro tends to look like
Most people describe a repeating rhythm: appetite lowest in the first two or three days after the injection, returning through the middle of the week, and hunger strongest just before the next dose. Our Mounjaro shot week guide goes through it day by day.
Muscle, and why we built this
Rapid weight loss takes some weight from lean tissue as well as fat, and how much varies a great deal between people and studies. Higher protein intake and resistance training throughout are the two things most consistently linked to keeping more of it. Recompose exists to make those two things survivable on a week where two days have no appetite in them. Read muscle loss on GLP-1 medication.
