How to use BMI Calculator + Calorie Deficit Planner
- Enter your stats. Drop in your current weight, height, age, and biological sex so the calculator can estimate your maintenance calories accurately.
- Set your training load. Pick the activity level that matches your weekly volume — light lifters and endurance athletes burn very different amounts.
- Choose a goal weight. Tell us where you want to land. If you're cutting to a class, use that exact target.
- Pick a timeframe. Set a realistic deadline. The tool will flag pacing that's too aggressive for your body and training demands.
- Read your daily deficit. We'll show your maintenance calories, target intake, and the deficit needed each day to hit your goal.
- Adjust and re-run. If the deficit feels brutal, stretch the timeline. Small tweaks beat blown-out training weeks.
