NIH Calorie Calculator – Estimate your daily calorie needs based on personal data and activity level.
Maintaining a healthy weight starts with understanding your daily caloric needs. The NIH Calorie Calculator is a powerful tool that estimates the number of calories your body requires based on factors like age, gender, weight, height, and activity level. This tool helps you make informed decisions about diet, exercise, and overall wellness.
What is the NIH Calorie Calculator?
The NIH Calorie Calculator, developed by the National Institutes of Health, calculates your Total Daily Energy Expenditure (TDEE). It considers your Basal Metabolic Rate (BMR)—the calories needed for basic bodily functions—and adjusts for your activity level to estimate how many calories you need to maintain, lose, or gain weight.
How the NIH Calorie Calculator Works
The calculator uses the following inputs:
- Age: Your current age in years.
- Gender: Male or female.
- Weight: Current weight in pounds or kilograms.
- Height: Height in inches or centimeters.
- Activity Level: Sedentary, lightly active, moderately active, very active, or extra active.
Using these values, the calculator estimates:
- Calories to Maintain Weight
- Calories to Lose Weight (Moderate or Aggressive)
- Calories to Gain Weight
