Weight Loss Equation:
From: | To: |
This calculator helps you determine your daily calorie intake needed to reach your weight loss goal within a specific time period (6-12 months). It's based on the principle that 1 kg of body fat contains approximately 7,700 kcal.
The calculator uses these equations:
Where:
Explanation: The equation calculates the daily calorie deficit needed to lose your target weight in the specified time, then subtracts this from your TDEE to give your recommended daily intake.
Details: Creating a calorie deficit is essential for weight loss. This calculator helps you determine a sustainable deficit for gradual, healthy weight loss over 6-12 months.
Tips: Enter your weight loss goal in kg, the time period in days (182 for 6 months, 365 for 12 months), and your calculated TDEE. All values must be positive numbers.
Q1: Why use 7700 kcal per kg?
A: Research shows 1 kg of body fat contains approximately 7,700 kcal of energy. This is an estimate as body fat composition varies slightly.
Q2: What's a healthy weight loss rate?
A: 0.5-1 kg per week is generally recommended for sustainable loss. This calculator helps plan for slower, more maintainable loss over 6-12 months.
Q3: How accurate is TDEE?
A: TDEE estimates vary. For best results, calculate your TDEE using multiple methods and track your actual weight changes to adjust.
Q4: Should I eat exactly these calories?
A: This is a starting point. Monitor your progress and adjust as needed based on your body's response.
Q5: What if I want to lose weight faster?
A: Larger deficits lead to faster loss but may be harder to maintain and can cause muscle loss. Consult a professional before aggressive deficits.
