What It Does
PSMF Diet calculates your personalized protein target based on your lean body mass, then helps you hit it every day. Log meals, track your weight against your LBM floor, and schedule refeeds and diet breaks — all without creating an account or sending your data anywhere.
Features
Protein Calculator Personalized daily protein target calculated from your lean body mass using the YMCA body fat formula. Fat and carb limits are included to keep you in a true PSMF.
Protein Tracker Log meals, save favorites for quick re-use, and monitor your protein goal and carb/fat limits throughout the day.
Progress Tracking Weight trend chart with your LBM floor shown as a reference line, so you always know how much fat you have left to lose and when to stop.
Diet Scheduling Refeed day and diet break scheduling based on your body type category, with reminders so you never miss a refeed.
Hydration Tracking Daily water goal tracking with visual progress and smart reminders.
Educational Resources Built-in PSMF guides and safety information backed by peer-reviewed research.
