1. What is a Weight Loss Speed Calculator?

Definition: This calculator estimates how much weight you can lose per week based on your daily calorie deficit.

Purpose: It helps people understand the relationship between calorie intake/expenditure and weight loss progress.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \text{Rate} \) — Weight loss rate (pounds per week)
• \( \text{Calories Deficit} \) — Daily calorie deficit (kcal)
• \( 3500 \) — Calories in one pound of body fat (kcal/pound)

Explanation: The daily calorie deficit is multiplied by 7 (days) and divided by 3500 to calculate weekly weight loss.

3. Importance of Calorie Deficit Calculation

Details: Understanding this relationship helps set realistic weight loss goals and maintain healthy progress.

4. Using the Calculator

Tips: Enter your estimated daily calorie deficit (difference between calories consumed and burned). Value must be > 0.
