Frequently Asked Questions
BMI (Body Mass Index) is a measurement that uses your height and weight to determine if your weight falls within a healthy range. It's calculated by dividing your weight in kilograms by your height in meters squared.
While BMI is a useful screening tool for most adults, it may not accurately reflect body composition for athletes with high muscle mass, pregnant women, or the elderly. Always consult with a healthcare professional for a comprehensive health assessment.
For most adults, a BMI between 18.5 and 24.9 is considered healthy. Below 18.5 is underweight, 25-29.9 is overweight, and 30 or above is considered obese.
For most people, checking BMI every 3-6 months is sufficient unless you're actively working on weight changes. Remember that BMI is just one indicator of health and should be considered alongside other factors.
