Cut — Evidence-Based Fitness

Cut is an evidence-based nutrition and body composition tracker for people who want honest numbers, not motivational noise. TARGETS YOU CAN TRUST Your BMR and TDEE are calculated from validated formulas (Mifflin-St Jeor, Katch-McArdle) with sources cited in-app. Cut shows you a TDEE range, not a fake-precise number — and tells you to calibrate it against your real weight trend. HONEST PROJECTIONS Pick a deficit and see projected fat loss, lean mass changes, and BMI over time — with warnings when a plan crosses evidence-based limits: too-fast loss rates, intake below micronutrient floors, metabolic adaptation past 10% weight loss. FOOD LOGGING WITHOUT FRICTION Search a database of 5M+ foods, log in seconds, quick-add when you don't need the library. Track protein, fat, and carbs against targets built from your goal. MICRONUTRIENTS, DEMYSTIFIED 95 nutrients with plain-language guidance: what's commonly under-dosed, what has a ceiling, what to test first, what skews labs. Track what matters for you. BODY COMPOSITION Tape-based body fat estimation (U.S. Navy method), measurement history, lean mass tracking. Log measurements for any day — including ones you forgot.
