Calorie Calculation Formula:
| From: | To: |
The Calorie Calculator estimates your daily energy needs based on your basal metabolic rate (BMR) and activity level. It uses the Mifflin-St Jeor equation for BMR calculation, which is considered the most accurate for healthy individuals.
The calculator uses two main formulas:
Mifflin-St Jeor Equation (BMR):
\[ \text{Male: } BMR = 10 \times weight + 6.25 \times height - 5 \times age + 5 \] \[ \text{Female: } BMR = 10 \times weight + 6.25 \times height - 5 \times age - 161 \]Total Daily Energy Expenditure (TDEE):
\[ Calories = BMR \times activity\_factor \]Where:
Details: Knowing your daily calorie needs helps with weight management, whether your goal is to lose, maintain, or gain weight. It provides a scientific basis for planning your diet.
Tips: Enter your weight in kg, height in cm, and accurate age. Select your gender and most appropriate activity level. For weight loss, consume fewer calories than calculated; for weight gain, consume more.
Q1: How accurate is this calculator?
A: It provides a good estimate for most people, but individual variations in metabolism may affect actual needs.
Q2: Should I eat exactly my calculated calories?
A: Use it as a starting point and adjust based on your weight changes and energy levels.
Q3: How often should I recalculate?
A: Recalculate after significant weight changes (5+ kg) or lifestyle changes.
Q4: Why different formulas for men and women?
A: Men typically have more muscle mass and higher metabolic rates at the same weight.
Q5: What if I'm very muscular or obese?
A: The calculator may overestimate for obese individuals and underestimate for very muscular individuals.
