How the Calorie Deficit Calculator Works

    The Secret to Healthy Weight Loss

    Weight loss happens through a simple principle: you need to burn more calories than you consume. This is called a calorie deficit.

    However, a very aggressive deficit can be harmful, causing muscle loss and metabolic problems. Understanding how to create a healthy deficit is crucial for sustainable results.

    Our Calorie Deficit Calculator helps you plan this process safely.

    How it Works

    The Basic Formula:

    (Weight Loss Goal in kg × 7700 kcal) ÷ (Timeframe in days) = Daily Calorie Deficit

    To lose 1 kg of fat: a deficit of ~7700 kcal is needed.

    For healthy loss (0.5 kg/week): a weekly deficit of 3850 kcal is needed (or 550 kcal/day).

    How to Create a Calorie Deficit

    Effective, but requires discipline.

    Increase Physical Activity

    Burn more calories through exercise.

    Improves overall health.

    Combine Both

    Allows for a moderate deficit from diet and exercise.
