Fat Burned vs Steps Journey

Ever wonder how much fat you actually burn in a day? FatBurn turns your Apple Health data into clear, actionable fat burn estimates — no guesswork, no calorie counting, no manual logging. Just open the app and see how much fat your body has burned today, during workouts, this week, and over your entire fitness history. HOW IT WORKS FatBurn uses established exercise physiology research to estimate fat oxidation from data already on your iPhone and Apple Watch: Heart rate samples from workouts and throughout the day Your age, weight, and biological sex from Health Workout duration, and intensity Calories are estimated using the Keytel formula (Keytel et al., British Journal of Sports Medicine, 2005). Fat burn is then calculated based on heart rate zone analysis — your body burns a higher percentage of fat at lower intensities and shifts toward carbohydrates at higher intensities. FatBurn classifies your effort into low, moderate, and vigorous zones and applies research-backed fat oxidation percentages to each. WHAT YOU SEE Daily Fat Burn — total fat burned from all activity and resting metabolism Workout Fat Burn — fat burned specifically during recorded workouts Weekly Trends — a 7-day chart showing daily fat burn with weekly totals Workout Breakdown — individual workout cards with fat burn, duration, and calories Lifetime Total — cumulative fat burned from your earliest HealthKit record Customizable Goals — set daily, workout, and weekly fat burn targets based on CDC and AHA guidelines All values display in grams or ounces, with support for kilograms and pounds for larger totals. APPLE WATCH APP FatBurn includes a full Apple Watch companion app so you can check your fat burn stats right from your wrist: Daily and workout fat burn at a glance Active calories, workout minutes, and weekly totals Syncs automatically with your iPhone via HealthKit Designed for quick, on-the-go reference WATCH COMPLICATIONS Add FatBurn to your watch face for instant access.

Every calculation is grounded in peer-reviewed research: Keytel Formula for calorie estimation from heart rate (J Sports Sci, 2005) Achten & Jeukendrup's Maximal Fat Oxidation research (Int J Sports Med, 2003) CDC weight loss guidelines (0.5–1.0 kg/week safe range) AHA physical activity recommendations (150 min/week moderate exercise) Full methodology with formulas and citations is available inside the app under Settings.
