1. What is the Weight Loss Formula?

The weight loss formula calculates expected weight reduction based on your Basal Metabolic Rate (BMR), activity level, caloric intake, and time period. It's based on the principle that 7700 kcal deficit equals approximately 1 kg of weight loss.

2. How Does the Calculator Work?

The calculator uses the weight loss equation:

Where:

• \( BMR \) — Basal Metabolic Rate (kcal/day)
• \( activity\_factor \) — Multiplier for physical activity level
• \( intake \) — Daily caloric intake (kcal/day)
• \( days \) — Time period (days)
• 7700 — kcal needed to burn 1 kg of fat

Explanation: The equation calculates your total caloric deficit over time and converts it to estimated weight loss.

3. Importance of Accurate Calculation

Details: Understanding your potential weight loss helps set realistic goals and create effective diet plans based on your metabolism and activity level.

4. Using the Calculator

Tips: Enter your accurate BMR (use a BMR calculator if needed), select appropriate activity factor, input your daily caloric intake, and specify the time period.

5. Frequently Asked Questions (FAQ)

Q1: What are typical activity factors?
A: Sedentary: 1.2, Lightly active: 1.375, Moderately active: 1.55, Very active: 1.725, Extremely active: 1.9

Q2: How accurate is this calculation?
A: It provides an estimate. Actual results may vary due to metabolic adaptation, water retention, and other factors.

Q3: Why 7700 kcal per kg?
A: This is the approximate energy contained in 1 kg of body fat, though individual composition may vary.

Q4: Should I aim for 7700 kcal deficit weekly?
A: Not necessarily. Very large deficits can be unhealthy. Consult a professional for personalized advice.

Q5: Does this account for muscle loss?
A: No, this assumes fat loss only. Proper protein intake and exercise help preserve muscle mass.
