How accurate is the calorie calculator?

Our calorie calculator uses scientifically proven formulas (Mifflin-St Jeor equation) to estimate your daily caloric needs with high accuracy based on your personal metrics.

What is the difference between BMR and TDEE?

BMR (Basal Metabolic Rate) is the calories your body burns at rest, while TDEE (Total Daily Energy Expenditure) includes calories burned through daily activities and exercise.

How much protein do I need daily?

Protein needs vary based on your goals: 0.8g per kg for maintenance, 1.2-1.6g per kg for muscle building, and 1.6-2.2g per kg for athletes and intense training.

Advanced Body Composition Analysis (Optional)

Enhanced Accuracy: Providing your body fat percentage enables the Katch-McArdle formula, which calculates your calorie and macronutrient needs based on lean muscle mass rather than total body weight—delivering significantly more precise results tailored to your unique physiology.

Body Fat Percentage (%):

Don't know your body fat percentage? No problem! Leave this field empty and the calculator will use the standard Mifflin-St Jeor formula. You can measure body fat using calipers, bioelectrical impedance scales, or DEXA scans.
