1. What is the Weight Loss Calories Calculator?

This calculator determines your recommended daily calorie intake to achieve your weekly weight loss goal based on your TDEE (Total Daily Energy Expenditure). It uses the scientific principle that 1 kg of body weight equals approximately 7700 calories.

2. How Does the Calculator Work?

The calculator uses the weight loss formula:

Where:

• \( TDEE \) — Total Daily Energy Expenditure (kcal/day)
• \( weekly\_loss\_kg \) — Desired weekly weight loss (kg/week)
• \( 7700 \) — Calories equivalent to 1 kg of body weight
• \( 7 \) — Days in a week

Explanation: The equation calculates the daily calorie deficit needed to achieve your weekly weight loss goal while accounting for your current energy expenditure.

3. Importance of Calorie Calculation

Details: Accurate calorie calculation is crucial for safe and effective weight loss. Too large a deficit can lead to muscle loss and metabolic slowdown, while too small may not produce results.

4. Using the Calculator

Tips: Enter your TDEE (use a TDEE calculator if unknown) and your desired weekly weight loss. A safe range is typically 0.25-1 kg per week.

5. Frequently Asked Questions (FAQ)

Q1: What is a safe rate of weight loss?
A: Generally 0.5-1 kg per week is considered safe and sustainable for most people.

Q2: How do I find my TDEE?
A: Use a TDEE calculator that considers your age, gender, weight, height, and activity level.

Q3: Why 7700 calories per kg?
A: Research shows 1 kg of body fat contains approximately 7700 kcal of energy.

Q4: Should I adjust my calories as I lose weight?
A: Yes, as you lose weight your TDEE decreases, so you should recalculate periodically.

Q5: Is it safe to go below 1200 (women) or 1500 (men) calories?
A: Not without medical supervision, as it becomes difficult to meet nutritional needs below these levels.
