Target calories represent the daily energy goal required to drive your selected body composition phase. Whether your goal is a deficit for fat loss, a surplus for muscle gain, or maintenance for recomposition, sizing this target accurately establishes the thermodynamic direction of your progress. BodyCompOS uses validated guidelines to translate your biological statistics and activity factors into highly customized caloric ranges.
1. How to Use & Apply This Target
Incorporate the target calorie calculation into your daily food logging. Treat this number as a consistent baseline. If your goal is fat loss, aim to hit your deficit target consistently. If your goal is hypertrophy, aim for your surplus target. Track weight averages weekly and adjust only after 2-4 weeks of consistent adherence.
2. Mathematical Assumptions & Formula Logic
This calculator derives calorie targets directly from estimated Total Daily Energy Expenditure (TDEE). The system applies a 15% deficit for fat loss, an 8% surplus for lean bulking, a 15% surplus for aggressive bulking, and a 2% deficit for body recomposition, ensuring metabolic safety.

Frequently Asked Questions
Q:How often should I recalculate my target calories?
Recalculate your targets after every 3-5 kg of weight change, or when you notice a steady progress plateau lasting more than 2-3 weeks. As your body weight changes, your resting metabolic rate and movement cost shift.
Q:Can I eat different calorie targets on weekends?
While consistency is key, you can shift calories across days as long as your weekly total remains aligned with your strategy. If weekend calories are higher, offset them slightly during weekdays.

TDEE Calculator
Estimate Total Daily Energy Expenditure, Basal Metabolic Rate (BMR), and maintenance calories using Mifflin-St Jeor BMR, refined with Katch-McArdle when body fat is available. TDEE is the starting foundation for all calorie planning, fat loss, and muscle gain strategy.
Calorie Calculator
Calculate daily calorie targets for fat loss (cutting at a moderate 15% deficit), lean bulk (8% surplus), aggressive bulk (15% surplus), or recomposition (98%). Moderate ranges optimize fat mobilization and muscle retention.
