How many calories do I need per day?

Your daily calorie needs depend on factors like age, gender, weight, height, and activity level. Kairo automatically calculates your Basal Metabolic Rate (BMR) and Total Daily Energy Expenditure (TDEE) based on your profile using the scientifically recognized Mifflin-St Jeor equation.

What is the difference between BMR and TDEE?

BMR (Basal Metabolic Rate) is the number of calories your body burns at rest to maintain basic functions. TDEE (Total Daily Energy Expenditure) includes your BMR plus calories burned through physical activity and digestion. TDEE is the total number of calories you need per day.

The Body Map is a unique Kairo feature that shows you at a glance how your nutrition supports different body systems — brain, heart, muscles, bones, digestion, and skin & immune system. It provides personalized insights based on your daily food intake.

What is BMI and how is it calculated?

BMI (Body Mass Index) is calculated by dividing your weight in kilograms by your height in meters squared: BMI = weight / (height in m)². A BMI of 18.5-24.9 is considered normal weight. Note that BMI does not account for muscle mass or body composition.
