Weight Loss Calories Formula:
From: | To: |
This calculator estimates the daily calorie intake needed for weight loss in women, based on the Mifflin-St Jeor Equation with a 500 calorie deficit for steady weight loss (about 0.5kg per week).
The calculator uses the formula:
Where:
Explanation: The equation calculates your Basal Metabolic Rate (BMR), adjusts for activity level, then subtracts 500 calories to create a deficit for weight loss.
Details: Accurate calorie estimation helps create a sustainable weight loss plan without extreme restriction that could lead to nutrient deficiencies or metabolic slowdown.
Tips: Enter your current weight in kg, height in cm, age in years, and select your activity level. For best results, use measurements taken in the morning before eating.
Q1: Why subtract 500 calories?
A: A 500 calorie daily deficit typically results in about 0.5kg (1lb) of weight loss per week, which is considered safe and sustainable.
Q2: Should I eat fewer calories for faster weight loss?
A: Not recommended. Very low calorie diets (<1200 kcal/day) should only be done under medical supervision and can lead to muscle loss and metabolic adaptation.
Q3: How accurate is this calculation?
A: It provides a good estimate but individual variations exist. Monitor your progress and adjust as needed.
Q4: When should I recalculate my calories?
A: Recalculate every 5-10kg of weight loss or if your activity level changes significantly.
Q5: What if I'm not losing weight at this calorie level?
A: Double-check your measurements, track accurately, and consider consulting a nutritionist. Metabolic adaptation or measurement errors may be factors.
