1. What is the Weight Loss Time Calculator?

This calculator estimates how long it will take to reach your weight loss goal based on your current weekly calorie deficit. It uses the scientific principle that 1 kg of body fat equals approximately 7,700 calories.

2. How Does the Calculator Work?

Where:

• Weight Loss — Your goal weight loss in kilograms
• Weekly Calorie Deficit — The difference between calories consumed and calories burned each week
• 7700 — Approximate calories in 1 kg of body fat

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