This tool helps you calculate your daily calorie deficit to achieve your weight loss goals.
How to Use the Calorie Deficit Calculator
This calculator helps you determine your ideal calorie intake to achieve a calorie deficit based on your age, gender, height, weight, activity level, and specific goal. To use the calculator, follow these steps:
- Enter your age in years.
- Select your gender.
- Enter your height in centimeters.
- Enter your weight in kilograms.
- Select your activity level from the dropdown menu.
- Choose your goal: Mild Deficit, Moderate Deficit, or Aggressive Deficit.
- Click the ‘Calculate’ button to see your maintenance calories and target calories.
How It Calculates
The Basal Metabolic Rate (BMR) is calculated using the Mifflin-St Jeor Equation, which varies slightly based on gender. The formula for calculating BMR is:
- For men: BMR = 10 * weight (kg) + 6.25 * height (cm) – 5 * age (years) + 5
- For women: BMR = 10 * weight (kg) + 6.25 * height (cm) – 5 * age (years) – 161
The BMR is then multiplied by an activity level factor to calculate the maintenance calories, which represents the total number of calories you need to maintain your current weight. The following activity level multipliers are used:
- Sedentary (little or no exercise): 1.2
- Lightly active (light exercise/sports 1-3 days/week): 1.375
- Moderately active (moderate exercise/sports 3-5 days/week): 1.55
- Very active (hard exercise/sports 6-7 days a week): 1.725
- Super active (very hard exercise, physical job or training twice/day): 1.9
Finally, the maintenance calories are multiplied by a goal factor to determine your target calories to achieve your desired calorie deficit:
- Mild Deficit: Maintenance Calories * 0.9
- Moderate Deficit: Maintenance Calories * 0.8
- Aggressive Deficit: Maintenance Calories * 0.7
Limitations
While this calculator provides a good estimate, individual variations such as metabolism differences, muscle mass, and other health factors can influence actual calorie needs. It is recommended to consult with a healthcare provider or a nutritionist for personalized guidance.
