When it comes to assessing general health and fitness, two commonly used indicators are body mass index (BMI) and body fat percentage (BFP). Both matrices provide insights into the body structure, but they measure different aspects of health. While BMI is an accelerated and simple calculation depending on height and weight, the body fat versus the lean mass gives a wider breakdown of the various body components.
Which one should you trust- BMI versus body fat percentage? How do these measurements affect your health insurance coverage, and which is best to access a plan for Family health insurance? Let's delve deeper to discover the comparison between BMI and body fat percentage.
What is BMI?
BMI (Body Mass Index) is a numerical value calculated using a person’s height and weight. It is a crucial tool used to classify individuals into various types of weight categories ranging from:
BMI Range
|
Category
|
Below 18.5
|
Underweight
|
18.5 – 24.9
|
Normal Weight
|
25 – 29.9
|
Overweight
|
30 and above
|
Obese
|
How to measure BMI?
To measure body mass index, use the following formula:
BMI = Weight (kg) / Height (m)²
For example, if a person weighs 70 kg and is 1.75 m tall, their BMI would be:
BMI = 70 / (1.75)² = 70 / 3.06 = 22.86
What is body fat percentage?
Body fat percentage (BFP) is the proportion of fat in your body compared to your total weight. It provides a detailed composition of body fat versus muscle, bone, and water weight.

How to measure body fat percentage?
There are several methods to measure your body fat:
· Skinfold Calipers – Measures fat thickness at different body parts.
· Bioelectrical Impedance Analysis (BIA) – Uses a small electrical current to estimate body fat.
· Hydrostatic Weighing – It measures body composition based on underwater weight.
· Dual-Energy X-ray Absorptiometry (DEXA) – A highly accurate scan to measure fat and muscle distribution.
Limitations of body fat percentage
1. Requires special equipment – Unlike BMI, body fat measurement often needs a device or professional assessment.
2. Can be expensive – Some developed and advanced methods such as DEXA scans or hydrostatic weighing can turn out to be expensive.
3. Results can vary – Different methods may provide slightly different types of results.
BMI versus body fat percentage: Which is more reliable?
1. Accuracy
· BMI provides a general estimate of weight categories but does not consider the body's muscle mass.
· Body fat percentage gives a clearer measure of fat levels in the body.
2. Ease of measurement
· The process to measure body mass index is quick and easy, as it uses just height and weight.
· Body fat percentage requires special equipment or professional assessment.
3. Health risk assessment
· BMI is good for large-scale population studies but may misclassify individuals.
· Body fat percentage provides a clearer picture of obesity-related risks such as heart disease and diabetes.
4. Use of health insurance
Health insurers often consider body mass index when assessing risk and health insurance premiums. However, a high BMI does not always mean poor health. Some insurers now consider waist-to-hip ratio or body fat percentage for a better risk assessment.
5. Consideration of body composition
· BMI does not lead to differentiation between fat, muscle, and bone mass, leading to significant misclassification.
· Body fat percentage precisely estimates fat levels and provides insights into muscle-to-fat ratio, which is very important for health assessment.
6. Impact on overall health and fitness goals
· BMI can be misleading for athletes and individuals with high muscle mass.
· Body fat percentage is a great indicator for those tracking fitness progress, weight loss, or muscle gain.
Thus, body fat percentage emerges as the more reliable metric for individual health assessments, while BMI remains very useful for quick, large-scale evaluations.
BMI vs. body fat: Which one you should trust?
If you are seeking an instant and easy estimate, BMI can give a rough idea of weight categories. However, for a detailed and accurate evaluation of your health risk, body fat is a better option to consider wisely.
For health insurance plans, BMI is still the most widely used metric. However, as consciousness increases, the insurers may include body fat percentage in the policy assessment process.
Final thoughts
Both BMI and body fat percentage are used to determine an individual's fitness, but body fat percentage is more accurate for measuring health risks. While BMI remains a standard health insurance assessment tool, insurance companies may soon include body fat percentages for better accuracy.

Frequently Asked Questions (FAQs)
1. Can BMI and body fat percentage be used together?
Yes, BMI versus body fat percentage can be used together. BMI gives a broad classification, while body fat percentage provides a detailed insight into fat distribution.
2. What is a healthy BMI for insurance eligibility?
Most health insurers consider a BMI of 18.5 – 24.9 as normal. A higher BMI may lead to increased premiums.
3. Is body fat percentage better than BMI for assessing obesity?
Yes, body fat percentage is more accurate as it distinguishes between muscle and fat.
4. Does health insurance cover obesity treatments?
Some insurers, including Generali Central Insurance, may cover obesity-related conditions if they cause health risks like diabetes or heart disease.
5. Can I lower my insurance premiums by reducing body fat?
Yes. Maintaining a healthy BMI and body fat percentage can improve eligibility for lower insurance premiums.
