Keep your muscle mode
Three things to hold on to
while the scale moves.
- 01
A protein floor for every day.
A daily protein minimum from your own target or your recent weight, shown with your calorie target. Simple high-protein foods for days when a full plate feels like too much.
- 02
Strength sessions, counted.
A weekly meter for at least two strength sessions. Fewer sets, done well, on the big movements. A short session still counts.
- 03
A calm flag if the pace is too fast.
If your weight trend drops faster than 1% of body weight a week, the app lets you know. The weekly smart check-in suggests a steadier calorie target. You decide.
Inside the app
Protein first.
Then the rest.
Log a meal in a few seconds and see where protein stands for the day. When appetite is low, eat the protein first. If you only finish half the plate, make it the right half.

Questions
A little clarity.
Who is Lean Mass Priority for?
Adults who are eating less than usual, whether from a smaller appetite or a planned weight-loss phase, and who want to keep the strength they have. It is general guidance, not a medical program.
How much protein will it ask for?
Your own protein target, if you have set one. Otherwise about 0.7 grams per pound of your recent average weight, kept between 90 and 220 grams a day. Your calorie and protein targets sit together, so you always see both.
What happens if I lose weight quickly?
If your trend falls faster than 1% of your body weight a week, Keep your muscle mode shows a short caution. It is a prompt to prioritize protein, keep lifting and, if a clinician guides your care, check in with them. It does not diagnose anything.
Do I have to lift heavy?
No. The emphasis is two to three strength sessions a week, every week, with fewer sets done well. On a low-energy day, do the first two exercises well and go home.
General guidance for healthy adults. If a clinician guides your nutrition or a medication affects your appetite, follow their plan. Results vary from person to person.
