Lose the fat. Keep the muscle.
The protein, strength and shot tracker built for people on GLP-1 medication.
For adults 18+. For tracking and education only. Not medical advice.
GLP-1s make it easy to eat less. That’s also why it’s easy to lose muscle.
Low appetite
Smaller meals are the point of the medication, but they can leave protein far below what your body needs.
Missed protein
When protein is low and muscles aren’t used, part of the weight you lose can come from muscle instead of fat.
Regain after stopping
Appetite can return when you stop or taper. Without a plan, the weight can creep back.

Questions, answered.
What is MuscleKeep?
MuscleKeep is a tracking app for adults using GLP-1 medication. It helps you hit a daily protein target, do short strength sessions, and keep track of doses, side effects and weight — so the weight you lose is more fat and less muscle.
Is it medical advice?
No. MuscleKeep is for tracking and education only. It never recommends or calculates doses. Talk to your doctor before changing your medication, diet or exercise.
Which medications does it work with?
It works with GLP-1 medications including tirzepatide and semaglutide injections and daily GLP-1 pills. You can also enter a compounded or other medication by name.
How is my protein target set?
We start from about 0.67 g of protein per pound of your goal weight, rounded and kept within a sensible range. You can change it any time, and we recommend checking targets with your care team.
Is my data private?
Yes. We don’t ask for your name or email, we don’t sell your data and we don’t use it for ads. Health data from Apple Health or Health Connect is only used to show your own progress.
Do you use AI?
Only if you allow it. Meal photo and text analysis use Google Gemini. We send the meal photo or text, the protein you have left today and symptom tags — never your name, medication or Health data.
How do I cancel?
