1. What is BMR and Weight Loss Timeline?

The Basal Metabolic Rate (BMR) is the number of calories your body needs at complete rest. The weight loss timeline estimates how long it will take to reach your goal based on your calorie deficit (TDEE - BMR - other factors).

2. How Does the Calculator Work?

The calculator uses the weight loss timeline equation:

Where:

• \( weight\_loss\_kg \) — Your weight loss goal in kilograms
• \( 7700 \) — Calories per kg of body fat
• \( TDEE \) — Total Daily Energy Expenditure (your maintenance calories)
• \( BMR \) — Basal Metabolic Rate (calories burned at rest)
• \( other \) — Additional caloric factors (exercise, etc.)

Explanation: The equation calculates how many days it will take to burn the calories equivalent to your weight loss goal at your current calorie deficit.

3. Importance of Accurate Calculation

Details: Understanding your BMR and realistic weight loss timeline helps set achievable goals and prevents unhealthy crash dieting. It accounts for individual metabolic differences.

4. Using the Calculator

Tips: Enter your BMR (use a BMR calculator if unknown), weight loss goal in kg, TDEE (maintenance calories), and any additional caloric factors. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why 7700 calories per kg?
A: Research shows 1 kg of body fat contains approximately 7700 kcal of energy.

Q2: How accurate is this calculation?
A: It provides an estimate. Actual results vary based on metabolic adaptation, water weight, and other factors.

Q3: What's the difference between BMR and TDEE?
A: BMR is calories burned at complete rest. TDEE includes all daily activities and exercise.

Q4: Is a larger deficit better for faster weight loss?
A: Too large a deficit can be unhealthy and lead to muscle loss. 500-1000 kcal deficit per day is generally recommended.

Q5: Why might my actual results differ?
A: Metabolism changes, measurement inaccuracies, water retention, and non-linear fat loss can affect results.
