About Calorie Calculation

Calorie requirements vary based on many factors including age, gender, weight, height, body composition, and activity level. This calculator uses scientifically-validated formulas to estimate your needs.

Basal Metabolic Rate (BMR)

BMR represents the calories your body needs to perform basic life-sustaining functions at rest. Different formulas calculate BMR:

  • Mifflin-St Jeor Equation: Considered the most accurate for the general population
  • Harris-Benedict Equation: A traditional formula that's been used for decades
  • Katch-McArdle Formula: Uses lean body mass for potentially better accuracy in athletic individuals
Total Daily Energy Expenditure (TDEE)

TDEE is your BMR multiplied by an activity factor. This represents your maintenance calories - what you need to maintain your current weight.

Macronutrients

Calories come from three main macronutrients:

  • Protein: 4 calories per gram - important for muscle repair and growth
  • Carbohydrates: 4 calories per gram - your body's preferred energy source
  • Fat: 9 calories per gram - essential for hormone production and vitamin absorption
Calorie Goals

To change your weight:

  • Weight Loss: Create a calorie deficit by consuming less than your TDEE
  • Maintenance: Consume calories equal to your TDEE
  • Weight Gain: Create a calorie surplus by consuming more than your TDEE

A sustainable rate of weight change is typically 0.5-1 kg (1-2 lbs) per week.

Understanding Maintenance Calories

Maintenance calories are the number of calories your body needs to maintain its current weight. These calories support your daily activities, including exercise and basic bodily functions.
