How to Use the NHS Calorie Calculator for Females
This calculator helps you estimate the number of calories you should consume daily to maintain your current weight, taking into account your age, weight, height, and activity level.
Instructions:
- Enter your age in years.
- Enter your weight in kilograms (kg).
- Enter your height in centimeters (cm).
- Select your activity level from the dropdown menu.
- Click the “Calculate” button to see your daily calorie requirement.
How the Calculation Works:
This calculator uses the Mifflin-St Jeor Equation to estimate Basal Metabolic Rate (BMR), which is the number of calories your body needs to perform basic functions. The equation for females is: 655 + (9.563 x weight in kg) + (1.850 x height in cm) – (4.676 x age in years).
The BMR is then multiplied by the activity factor you selected to estimate your Total Daily Energy Expenditure (TDEE), which indicates how many calories you need per day to maintain your weight.
Limitations:
Please note that this calculator provides an estimate and may not be 100% accurate for everyone. Factors such as muscle mass, medical conditions, and metabolism can affect your calorie needs. Always consult with a healthcare provider for personalized advice.
