How to Use the Calorie Calculator

Step 1: Enter Your Information

Provide your basic details:

  • Age (years)
  • Gender (affects metabolic calculations)
  • Weight (in pounds or kilograms)
  • Height (in feet/inches or centimeters)

Step 2: Select Activity Level

Choose your activity level to calculate your Total Daily Energy Expenditure (TDEE). This accounts for your daily physical activity.

Step 3: Choose Your Goal

Select whether you want to maintain, lose, or gain weight. The calculator will adjust your calorie recommendations accordingly.

How the Calorie Calculator Works

BMR Calculation (Mifflin-St Jeor Equation)

The calculator uses the most accurate BMR formula:

Men: BMR = 10 × weight(kg) + 6.25 × height(cm) - 5 × age(years) + 5
Women: BMR = 10 × weight(kg) + 6.25 × height(cm) - 5 × age(years) - 161

BMR (Basal Metabolic Rate) is the calories your body needs at rest.

TDEE Calculation

Total Daily Energy Expenditure is calculated by multiplying BMR by activity factor:

Sedentary BMR × 1.2
Lightly Active BMR × 1.375
Moderately Active BMR × 1.55
Very Active BMR × 1.725
Extremely Active BMR × 1.9

Key Definitions

Metabolic Terms

Basal Metabolic Rate (BMR)

The number of calories your body needs to perform basic functions like breathing, circulation, and cell production while at rest.

Total Daily Energy Expenditure (TDEE)

The total number of calories you burn in a day, including BMR plus calories burned through physical activity.

Calorie Deficit

When you consume fewer calories than you burn, leading to weight loss (typically 500-1000 calories per day).

Macronutrients

Protein

Essential for muscle building and repair. Recommended: 0.8-1.2g per kg body weight.

Carbohydrates

Primary energy source. Recommended: 45-65% of total calories.

Fats

Essential for hormone production and nutrient absorption. Recommended: 20-35% of total calories.

Pro Tips for Using the Calorie Calculator

📊 Accurate Measurements

Use accurate weight and height measurements for the most precise calorie calculations.

🏃 Activity Level

Be honest about your activity level. Overestimating can lead to consuming too many calories.

🎯 Realistic Goals

Aim for 1-2 pounds of weight loss per week. More aggressive goals may not be sustainable.

🔄 Regular Updates

Recalculate your needs as your weight changes to maintain accuracy.
