How does the Calorie Calculator work?

First, the calculator estimates your Basal Metabolic Rate (BMR) using the Mifflin-St Jeor equation.

Maintenance Calories = BMR x Activity Factor

Maintenance calories are an estimate of the energy required to maintain your current body weight at the selected activity level.

The goal options then show simple calorie adjustments around that maintenance estimate.

Important: These calorie figures are estimates for general informational use and are not individualized dietary prescriptions. Energy requirements vary between people. Calorie restriction may be inappropriate for some people, including during pregnancy, while breastfeeding, for people under 18, or when medical or nutritional conditions require individualized care.

Vedicaly's Calorie Calculator helps estimate your daily calorie needs based on information such as age, sex, height, weight and activity level. The result provides an estimate of the energy your body may require each day.

What Are Calories?

Calories are units of energy. Food and drinks provide energy that the body uses for essential functions, physical activity and everyday tasks. Individual calorie requirements vary depending on several personal and lifestyle factors.

What Affects Daily Calorie Needs?

Daily calorie needs can vary according to factors such as age, sex, body size and physical activity. People who are more physically active generally use more energy than people with lower activity levels.

Are calculated calorie needs exact?

No. Calorie calculators provide estimates based on formulas and the information entered. Actual energy requirements can vary between individuals.

Is a calorie estimate the same for everyone?

No. Two people can have different calorie requirements even if some of their measurements are similar. Activity level, body composition and other individual factors can influence energy needs.
