Calorie Calculator

Basal Metabolic Rate (BMR) is the number of calories your body burns at rest to maintain basic life functions like breathing, circulation, and cell production.

Total Daily Energy Expenditure (TDEE) is your BMR multiplied by an activity factor. It represents the total calories you burn in a day including exercise and daily activities.

A moderate calorie deficit of 500 calories below your TDEE leads to approximately 0.5 kg (1 lb) of weight loss per week. Extreme deficits are not recommended.

Macronutrients (macros) are protein, carbohydrates, and fat. A balanced diet typically includes 25-35% protein, 45-55% carbs, and 20-30% fat of total calories.
