Calorie Calculator Weight Loss

Introduction: Effective weight loss involves a careful balance of calorie intake and expenditure. The Calorie Calculator Weight Loss tool is designed to help you estimate the daily calories needed for weight loss based on factors such as gender, age, weight, height, activity level, and weight loss goal.

Formula: The calculator uses the Harris-Benedict equation to estimate the Basal Metabolic Rate (BMR) and adjusts it based on the selected activity level. It then incorporates the weight loss goal by assuming a caloric deficit of 7700 calories per kilogram for weight loss.

How to Use:

  1. Select your gender from the dropdown menu.
  2. Enter your age in years.
  3. Input your weight in kilograms.
  4. Specify your height in centimeters.
  5. Choose your activity level from the options provided.
  6. Enter your weight loss goal in kilograms.
  7. Click the “Calculate” button to get your estimated daily calorie needs for weight loss.

Example: For example, a 35-year-old female who weighs 80 kilograms, is 170 centimeters tall, has a moderately active lifestyle, and aims to lose 2 kilograms. After inputting these values and clicking “Calculate,” the calculator will provide an estimate of the daily calories needed for effective weight loss.
