What the result means
The result is a practical daily planning estimate. Use the health score and status to judge whether your target is balanced, aggressive, or needs adjustment.
BMR = Mifflin-St Jeor. TDEE = BMR × activity factor. Goal calories = TDEE ± adjustment.
This calculator is for general wellness planning only and does not replace professional medical advice.
Example calculation
Using the default values, the calculator estimates a daily target, compares it with the selected goal, and returns a health score for quick decision-making.
Tips for better results
- Use consistent units and update inputs when your body weight or training level changes.
- Compare the result with weekly trends rather than one isolated day.
- Avoid extreme changes; gradual adjustments are easier to maintain.
FAQ
How many calories should I eat to lose 1 pound per week?
A 500 kcal daily deficit is commonly used as a rough estimate for about 1 pound per week, but real results vary by activity and adherence.
Is eating below my BMR unhealthy?
Eating below BMR for long periods can be too aggressive for many people. Use it only with professional guidance.
How many calories do I need to maintain my weight?
Maintenance calories are estimated by multiplying BMR by your activity factor.
How much calorie deficit is considered safe?
A moderate deficit around 10–20% below TDEE is usually more sustainable than a severe restriction.
How does activity level affect calorie needs?
Higher activity increases TDEE, which raises maintenance calories and allows more flexible calorie targets.
