How To Calculate How Many Calories I Eat

Calculating your daily calorie intake is crucial for maintaining a healthy weight and overall well-being. This calculator helps you estimate your daily calorie needs based on your age, weight, height, gender, and activity level.

1. Enter your age, weight, height, and select your gender.
2. Choose your activity level from the dropdown menu.
3. Click the ‘Calculate’ button to see your estimated daily calorie intake.

The calculator uses the Mifflin-St. Jeor equation to estimate your Basal Metabolic Rate (BMR), which is then multiplied by your activity level to determine your Total Daily Energy Expenditure (TDEE).

• Track your calorie intake using a food diary or a calorie-tracking app.

• Consult a healthcare professional or a registered dietitian for personalized advice.
