Weight Loss Duration Formula

Formula
$$\text{Days to Lose Weight} = \frac{( \text{Current Weight} – \text{Target Weight} ) \times 7700}{\text{Daily Calorie Deficit}}$$

Explanation:
Each kilogram of body fat is roughly equivalent to 7700 calories. By dividing the total calorie difference by your daily deficit (e.g., 500 kcal), you can estimate how long it will take to lose the desired weight.

This tool is perfect for anyone who wants to set a realistic weight loss goal. By creating a calorie deficit of up to 500 kcal per day, you can achieve gradual and sustainable results. The calculator provides an estimated duration based on your current and goal weight, helping you track progress and plan a healthier lifestyle.
