1. What is a Calorie Deficit?

A calorie deficit occurs when you consume fewer calories than your body expends. This energy imbalance forces your body to use stored fat for energy, resulting in weight loss over time.

2. How Does the Calculator Work?

The calculator uses the calorie deficit formula:

Where:

• 3500 — Calories in one pound of body fat
• lb per week — Desired weight loss rate in pounds per week
• 7 — Days in a week

Explanation: This formula calculates the daily calorie deficit needed to achieve your desired weekly weight loss goal, based on the principle that 3500 calories equals approximately one pound of body fat.

3. Importance of Calorie Deficit for Weight Loss

Details: Creating a consistent calorie deficit is the fundamental principle behind weight loss. Understanding your required deficit helps you plan appropriate dietary changes and exercise routines to achieve sustainable weight loss.

4. Using the Calculator

Tips: Enter your desired weekly weight loss rate in pounds. For sustainable weight loss, most experts recommend aiming for 1-2 pounds per week. Values must be positive numbers.
