NHS Calorie Intake Formula:
| From: | To: |
The NHS (National Health Service) calorie intake formula calculates daily energy requirements by multiplying Basal Metabolic Rate (BMR) with Physical Activity Level (PAL). This provides an estimate of the calories needed to maintain current weight based on individual metabolic rate and activity level.
The calculator uses the NHS formula:
Where:
Explanation: BMR represents the calories your body needs at rest, while PAL accounts for your daily activity level. Multiplying these gives your total daily energy expenditure.
Details: Accurate calorie intake estimation is crucial for weight management, ensuring adequate energy for daily activities, and maintaining overall health and wellbeing according to NHS guidelines.
Tips: Enter your BMR in kcal/day and select your appropriate PAL level from the dropdown menu. All values must be valid (BMR > 0, PAL > 0).
Q1: How do I calculate my BMR?
A: BMR can be calculated using various formulas (e.g., Mifflin-St Jeor, Harris-Benedict) based on age, gender, height, and weight.
Q2: What PAL level should I choose?
A: Choose based on your daily activity: Sedentary (office work), Lightly active (light exercise 1-3 days/week), Moderately active (moderate exercise 3-5 days/week), Very active (hard exercise 6-7 days/week), Extra active (very hard exercise, physical job).
Q3: Is this calculation accurate for weight loss?
A: This calculates maintenance calories. For weight loss, subtract 500 kcal/day for approximately 0.5kg loss per week, as recommended by NHS.
Q4: Should I adjust my intake for special conditions?
A: Yes, pregnant women, athletes, or those with medical conditions should consult healthcare professionals for personalized advice.
Q5: How often should I recalculate my calorie needs?
A: Recalculate when your weight changes significantly, activity level changes, or every few months to ensure accuracy.
