Measurement tips:
- • Weigh yourself in the morning, without clothes
- • Measure height without shoes, standing straight

Important Considerations:
BMI is a screening tool that estimates body fat based on weight and height. It's widely used but has limitations and should be interpreted alongside other factors.
Limitations:
- • Doesn't distinguish between muscle and fat mass
- • May not be accurate for athletes with high muscle mass
- • Different standards may apply for different ethnic groups
- • Age and sex variations not accounted for
Always consult healthcare professionals for comprehensive health assessment and personalized weight management advice.
