Calorie Calculator
The Calorie Calculator is a free online tool designed to help individuals calculate their daily calorie needs for weight loss, maintenance, or gain. By providing information about age, sex, weight, height, and activity level, users can get an estimate of their basal metabolic rate (BMR) and daily calorie requirements. Whether you're trying to lose weight, maintain weight, or gain weight, this calculator is a valuable resource for anyone looking to achieve their fitness goals and live a healthier lifestyle. With its easy-to-use interface and accurate calculations, the Calorie Calculator is an essential tool for anyone seeking to manage their weight and improve their overall health.
How the Calorie Calculator Works
The Calorie Calculator uses a formula to estimate an individual's daily calorie needs based on their BMR and activity level. The formula is as follows:
BMR (men) = 66 + (6.2 x weight in kg) + (12.7 x height in cm) - (6.76 x age in years)
BMR (women) = 655 + (4.35 x weight in kg) + (4.7 x height in cm) - (4.7 x age in years)
Daily calorie needs are then calculated by multiplying the BMR by an activity factor, ranging from 1.2 for sedentary individuals to 1.9 for extra active individuals.
| Activity Level | Calorie Needs Multiplier |
|---|---|
| Sedentary (little or no exercise) | 1.2 |
| Lightly active (light exercise/sports 1-3 days/week) | 1.375 |
| Moderately active (moderate exercise/sports 3-5 days/week) | 1.55 |
| Very active (hard exercise/sports 6-7 days a week) | 1.725 |
| Extra active (very hard exercise/sports & physical job or 2x training) | 1.9 |
