- View Results: The calculator will display your recommended daily energy intake based on the details provided.
Formula for Energy Intake Calculation
The energy intake calculator uses the Mifflin-St Jeor Equation, one of the most accurate formulas for calculating Basal Metabolic Rate (BMR) and Total Daily Energy Expenditure (TDEE).
Mifflin-St Jeor Equation:
- For Men:
BMR=10×weight (kg)+6.25×height (cm)−5×age (y)+5 - For Women:
BMR=10×weight (kg)+6.25×height (cm)−5×age (y)−161
To find TDEE:
TDEE=BMR × Activity Level
Activity Levels:
- Sedentary (little or no exercise): ×1.2
- Lightly active (light exercise/sports 1-3 days/week): ×1.375
- Moderately active (moderate exercise/sports 3-5 days/week): ×1.55
- Very active (hard exercise/sports 6-7 days a week): ×1.725
- Super active (very hard exercise/sports & physical job): ×1.9
Example Calculation
Suppose you are a 30-year-old woman, weighing 70 kg, 165 cm tall, and you exercise moderately. Here’s how you would calculate your TDEE:
- Calculate BMR:
BMR=10×70+6.25×165−5×30−161=1417.5 - Apply activity level (moderately active):
TDEE=1417.5×1.55=2197.125
So, your daily energy intake should be approximately 2197 calories.
FAQs
What is Basal Metabolic Rate (BMR)?
BMR is the number of calories your body needs to maintain basic physiological functions at rest.
How accurate is the Mifflin-St Jeor Equation?
The Mifflin-St Jeor Equation is considered one of the most accurate for estimating BMR and TDEE, with an accuracy rate of about 5%.
Can this calculator help with weight loss?
Yes, by knowing your TDEE, you can create a calorie deficit to aid in weight loss.
Should I consult a professional before making dietary changes?
It’s always recommended to consult with a healthcare or nutrition professional before making significant changes to your diet.
Conclusion
Calculating your daily energy intake is essential for maintaining a balanced and healthy lifestyle. With the energy intake calculator, you can easily determine your daily calorie needs and tailor your diet to meet your health goals. Whether you’re looking to lose weight, build muscle, or simply maintain your current health, understanding your energy intake is a crucial step.
