What is a Calorie Calculator?

 

A calorie calculator is a nutrition and fitness tool that estimates your daily calorie needs based on factors such as age, sex, height, weight, and activity level. It works by first calculating your Basal Metabolic Rate (BMR) — the number of calories your body burns at rest — and then adjusting for your physical activity to determine your Total Daily Energy Expenditure (TDEE).

 

By knowing your daily calorie requirements, you can:

Create a calorie deficit for safe and effective weight loss.

Build a calorie surplus for muscle gain and bulking.

Maintain your weight by balancing calorie intake and calorie burn.
