Whether you want to lose weight, cut body fat, or just understand your numbers, CutCal turns the science of a calorie deficit into one clear daily target — and the simple tools to actually hit it.

WHY A CALORIE DEFICIT?
Weight loss comes down to one principle: eat fewer calories than you burn. CutCal works out how many calories you burn each day (your maintenance calories, or TDEE) and subtracts a safe deficit, so you lose weight at a steady, sustainable pace.

YOUR DAILY TARGET
• Calorie deficit calculator — your exact daily calorie target for weight loss
• Maintenance calories (TDEE) from the trusted Mifflin–St Jeor equation (Katch–McArdle when you add body-fat %)
• Pick your pace — 0.25, 0.5 or 0.75 kg (0.5–1.5 lb) per week
• Choose a macro split — balanced, high-protein or low-carb
• Estimated goal date so you know exactly when you'll get there
• Safe calorie minimums so your target never drops too low

LOG FOOD THE EASY WAY
• Scan barcodes for instant nutrition (Open Food Facts)
• Search foods by name, or quick-add calories offline
• Tracks calories and macros (protein, carbs, fat) — fiber & sugar with Pro
• Favorites, meal templates and copy-yesterday for one-tap re-logging
• Water tracking plus a clean Home dashboard calorie ring

TRACK ACTIVITY & NET CALORIES
• Log workouts — walking, running, cycling, swimming, weights, HIIT, yoga and more (MET-based)
• Keep activity calories separate, or add them back to your daily budget
• Net intake updates live: food in, exercise out

INTERMITTENT FASTING
• Fasting tracker — 16:8, 18:6, 20:4, OMAD, 24h or custom windows
• Manual or Auto mode (logging food can end your fast and start the eating window)
• Live countdown, fasting streaks and completion reminders
