Weight Loss Calculation:
From: | To: |
This calculator helps women determine the daily calorie intake needed to reach their weight loss goal by a specific target date. It calculates the required calorie deficit based on the weight difference and time period.
The calculator uses these formulas:
Where:
Explanation: The calculation is based on the principle that 1 kg of body fat contains approximately 7700 calories, so creating a daily deficit of (7700 × kg to lose) ÷ days will result in the target weight loss.
Details: Creating a consistent calorie deficit is the most scientifically validated method for weight loss. This calculator helps determine a safe and sustainable deficit to reach your goal by your target date.
Tips: Enter your current weight, goal weight, target date, and TDEE (use a TDEE calculator if unsure). The calculator will show the required daily calorie intake to reach your goal.
Q1: Is 7700 kcal really equal to 1 kg of fat?
A: This is an approximation. The exact energy content of body fat can vary slightly, but 7700 kcal/kg is the widely accepted value for calculations.
Q2: What if my calculated daily calories are very low?
A: Extremely low calorie targets may not be sustainable or healthy. Consider extending your target date or consulting a nutritionist.
Q3: Why is this specifically for women?
A: Women typically have different metabolic rates and fat distribution than men. For men, the calculations might need slight adjustments.
Q4: How accurate is this calculator?
A: It provides theoretical values. Actual results may vary due to metabolic adaptation, water retention, and other factors.
Q5: Should I eat exactly the calculated calories every day?
A: The calculation shows an average. You can vary daily intake as long as the weekly average matches the target.
