Can I use BMI to plan my weight loss?

Yes, BMI gives you a realistic weight target based on your height. You can use it along with a weight loss calculator to set specific goals and track progress.

Is BMI a reliable measure of health?

BMI is a useful screening tool but doesn't consider muscle mass, bone structure, or fat distribution. It should be used along with other health metrics like body fat percentage or waist measurements.

What BMI range is considered healthy?

A BMI between 18.5 and 24.9 is considered healthy for most adults. This range is associated with a lower risk of chronic diseases.

📖 What Is BMI (Body Mass Index)?

Body Mass Index (BMI) is a simple screening tool used globally to assess whether your weight is within a healthy range based on your height. While it doesn’t directly measure fat, it gives a good estimate of whether you’re underweight, at a healthy weight, overweight, or obese.

✅ Formula:
BMI = weight (kg) ÷ (height in meters)²
🔍 Example:
If your weight is 70 kg and height is 1.75 meters,
BMI = 70 / (1.75 × 1.75) = 22.86

📊 BMI Classification – Know Your Category

According to World Health Organization (WHO) standards, BMI values are grouped as follows:

⚖️ Is BMI Always Accurate?

Not quite. BMI is a broad tool, and it doesn’t consider everything:

Limitation	What It Misses
Muscle vs Fat	Athletes may have higher BMI due to muscle mass
Fat Distribution	Visceral vs subcutaneous fat not considered
Age & Gender Variance	Older adults & women have different fat ratios
Ethnic Differences	Risks vary across populations at the same BMI
Fitness & Metabolic Markers	Ignores blood pressure, glucose, and cholesterol

✅ This is why BMI is best used with other tools, like:

Body Fat Percentage Calculators
Waist-to-Height Ratio
Fitness & medical screenings

🔍 Why BMI Alone Isn’t a Full Health Picture

Your weight isn’t the only thing that matters. Someone with a “normal” BMI could still have health issues, and someone with a high BMI might be metabolically healthy.

BMI doesn’t measure:

Heart health
Mental health
Diet quality
Physical activity
Sleep habits
