BMI Calculator
What is BMI (Body Mass Index)?
Body Mass Index (BMI) is a simple index of weight-for-height that is commonly used to classify underweight, overweight, and obesity in adults. It allows you to estimate your body fat levels using only your height and weight, without the need for complex equipment. BMI is widely used by healthcare professionals globally as a preliminary screening tool.
💡 Formula: BMI = Weight (kg) ÷ {Height (m) × Height (m)}
Understanding Your BMI Result
While BMI is a useful indicator, standards may vary slightly by region (e.g., WHO vs. Asia-Pacific guidelines). Generally, the ranges are interpreted as follows:
- Underweight (Below 18.5): You may need to gain weight through a balanced diet and strength training.
- Normal Weight (18.5 – 22.9): You are in a healthy range. Maintain your current lifestyle!
- Overweight (23 – 24.9): This is a warning sign ("Pre-obese"). It's a good time to start managing your weight.
- Obese (25 and above): Increased risk of health issues such as heart disease and diabetes. Weight loss is recommended.
Tips for Maintaining a Healthy Weight
1. Eat a Balanced Diet
Avoid extreme diets. Instead, focus on regular meals rich in protein, fiber, and essential nutrients.
2. Stay Active
Aim for at least 30 minutes of moderate aerobic exercise, such as brisk walking or jogging, 3 to 5 times a week.
3. Hydration and Sleep
Drinking plenty of water and getting 7+ hours of quality sleep helps regulate your metabolism and prevents overeating.
