Calorie Equation for Weight Loss:
From: | To: |
This calculator estimates the daily calorie intake needed for women to lose weight safely (about 0.5 kg per week) based on their basal metabolic rate (BMR) and activity level.
The calculator uses the following equation:
Where:
BMR Calculation (Mifflin-St Jeor for Women): \[ BMR = (10 \times weight\ in\ kg) + (6.25 \times height\ in\ cm) - (5 \times age) - 161 \]
Details: Accurate calorie estimation is crucial for safe and effective weight loss. A 500-calorie daily deficit typically results in about 0.5 kg of weight loss per week.
Tips: Enter your current weight in kg, height in cm, age in years, and select your activity level. For best results, measure your weight and height accurately.
Q1: Why subtract 500 calories?
A: A 500-calorie daily deficit creates about 3500 calories weekly deficit, which equals approximately 0.5 kg of fat loss.
Q2: Is this calculator only for women?
A: Yes, this uses the female-specific BMR equation. Men should use a different calculator.
Q3: How accurate is the BMR calculation?
A: Mifflin-St Jeor is about 70-80% accurate for most people. Individual variations exist.
Q4: Can I create a larger deficit?
A: Not recommended. Deficits >500-750 calories/day may cause muscle loss and metabolic slowdown.
Q5: Should I adjust as I lose weight?
A: Yes, recalculate every 4-5 kg lost as your BMR decreases with weight loss.
