What is the minimum safe daily calorie intake?
Generally, adult women should rarely consume fewer than 1,200 kcal/day and adult men fewer than 1,500 kcal/day without medical supervision.
Calorie Calculator
Calculates your baseline maintenance calories and provides tailored target caloric intakes for mild, moderate, and aggressive cutting or bulking goals.

Equation: Mifflin-St Jeor Energy Expenditure Model | Peer-Reviewed Source: Journal of the Academy of Nutrition and Dietetics
Target Calories = BMR × Activity Multiplier ± Deficit/Surplus
Calculates BMR and applies physical activity factors, then provides calibrated energy targets based on 250, 500, and 750 kcal daily adjustments.
Step-by-Step Worked Example: Weight Loss Calorie Target
- Deficit for 1 lb/week fat loss: 500 kcal/day
- Subtract deficit: 2500 - 500 = 2000 kcal/day
Calculation Result: Target = 2,000 kcal/day
Clinical Nuances, Limitations & Best Practices
- Assumes a static deficit; metabolic adaptation may require minor downward adjustments over prolonged dieting phases.
