Our NHS calorie calculator and BMI tool will help you quickly determine your daily calorie needs and assess your body mass index.
How to Use the NHS Calorie and BMI Calculator
This calculator assists in estimating your daily caloric needs based on your Basal Metabolic Rate (BMR) and activity level, as well as calculating your Body Mass Index (BMI).
Steps to Use the Calculator:
- Enter your age in years.
- Select your gender from the dropdown menu.
- Enter your weight in kilograms.
- Enter your height in centimeters.
- Select your activity level from the available options.
- Click the “Calculate” button to get your daily caloric needs and BMI.
How It Calculates Results:
The calculator uses the Harris-Benedict equation to estimate your BMR. Your BMR represents the number of calories you’d burn per day if you were at rest. This number is then multiplied by an activity factor to estimate your total daily energy expenditure (TDEE).
The BMI is calculated using the standard formula: BMI = weight (kg) / height^2 (m²). This provides an estimate of your body fat based on your height and weight.
Limitations:
- This calculator provides an estimate and should not be used as a substitute for professional medical advice.
- The BMI may not accurately reflect body fat percentage for all individuals, especially athletes or those with a muscular build.
- Caloric needs can vary based on additional factors not accounted for in this calculator, such as muscle mass, metabolic health, and specific health conditions.
