Frequently Asked Questions
How is BMI calculated?
BMI is calculated by dividing your weight in kilograms by your height in meters squared. Formula: BMI = weight (kg) / height (m)²
What's the difference between BMR and TDEE?
BMR is your basal metabolic rate (calories at rest), while TDEE includes all the calories you burn with physical activity and daily movement.
How many calories should I consume to lose weight?
For healthy weight loss, a deficit of 300-500 calories daily from your TDEE is recommended. This allows you to lose approximately 0.5 kg per week.
Is BMI accurate for everyone?
BMI is a general guide but has limitations. It doesn't consider body composition (muscle vs fat), so muscular athletes may have a high BMI but be healthy.
