Daily calorie estimates are easier when activity is included
Calorie planning usually needs more than a resting baseline because activity level changes how much energy is used across a typical day.
This calculator builds on a BMR-style estimate and adds activity plus simple goal adjustments so the result is more practical for everyday planning.
Helpful tips for a better result
- Choose the activity level that best matches your typical routine, not your best day.
- Use the maintenance result as a starting point rather than a perfect guarantee.
- Compare the maintenance, loss, and gain targets before making larger changes.
Frequently asked questions
Does this include activity level?

Can I see calorie targets for different goals?
Yes. The calculator provides simple maintenance, gain, and loss-style targets.
Is this medical or nutrition advice?
No. It is a general planning estimate and not a replacement for professional guidance.
