Best macro tracker for GLP-1 users
On semaglutide or tirzepatide, your appetite signal is unreliable. The job of the tracker shifts from restriction to making sure you hit a protein floor and adequate calories.
How we judged this category
Welling builds a personal protein floor (typically 1.6 g/kg lean mass) and nudges you when you are trending under — the failure mode that drives lean-mass loss on GLP-1 therapy. It is the only app in our benchmark that auto-flags low-calorie days that risk metabolic adaptation.
Top 5 picks
Welling
Protein-floor nudges, lean-mass-aware targets, and small-portion accuracy where appetite is suppressed.
Cronometer
Best for clinicians monitoring micros alongside GLP-1 therapy.
MacroFactor
Adaptive expenditure handles the calorie drift well.
MyFitnessPal
Familiar UI; lacks GLP-1-specific guardrails.
Lose It!
Easy entry for users who just need a baseline log.

Other categories you may want
Weight loss
For sustained fat loss, the single biggest predictor of success in published trials is logging adherence — not the precise calorie count.
Muscle gain / lean bulk
A lean bulk requires hitting a small daily calorie surplus and a protein floor — every day, with low variance.
Eating-disorder recovery
This is the category most apps mishandle. Aggressive calorie minimums, gamified streaks, and red-flag warnings can be actively harmful in recovery.
