How to use this calculator
- Enter your planned daily calorie deficit or surplus gap.
- Add body weight, workout duration, and workout days per week.
- Review estimated exercise contribution and weekly fat-loss projection.
Balance your diet and exercise plan. This calculator estimates workout calorie burn, compares it with your calorie gap, and shows whether your weekly exercise plan supports sustainable fat loss without relying on extreme restriction.
The result estimates how much weekly progress comes from diet plus exercise and flags whether the balance is practical.
The calculator assumes moderate mixed training. Actual burn differs by workout type, intensity, and fitness level.
A 500 kcal daily deficit plus four 45-minute workouts at 75 kg can produce roughly 4,800 kcal weekly deficit, or about 0.6 kg fat equivalent.
One pound of fat is often approximated as 3,500 kcal, but real progress varies with water, metabolism, and adherence.
Running, cycling, rowing, and swimming can burn many calories, but the best workout is the one you repeat consistently.
Daily movement is useful, but hard workouts need recovery. Many people combine several workouts with daily walking.
Cardio burns calories efficiently, while strength training helps preserve muscle during weight loss.
The right target depends on your calorie deficit, recovery, training level, and sustainability.
