Our MSJ Calorie Calculator helps you determine your daily calorie needs for maintaining or adjusting your weight.
How to Use the MSJ Calorie Calculator
Fill out the form with your personal information such as age, gender, weight, height, activity level, and your weight goal. Then click the “Calculate” button to see your daily calorie needs.
How It Calculates the Results
The calculator uses the Mifflin-St Jeor (MSJ) equation to estimate your Basal Metabolic Rate (BMR) based on your gender, weight, height, and age. It then adjusts the BMR by your activity level to estimate your maintenance calories. Depending on your weight goal, it further adjusts the result to either help you lose or gain weight.
Limitations
Please note this calculator provides an estimate of daily calorie needs, and actual needs may vary based on other factors such as muscle mass, metabolic health, and other lifestyle aspects. Consultation with healthcare or nutrition professionals is recommended for personalized advice.
