When it comes to managing your weight, you’ve likely come across terms like BMI and body fat percentage, but what do they actually mean? And more importantly, which one gives you a clearer picture of your overall health?
At Hodgson Pharmacy in Longfield, we work with individuals across Dartford, Gravesend, and the surrounding areas to help them understand their health beyond just a number on the scales. Here’s how BMI and body fat percentage compare and why it’s helpful to track both.
What Is BMI?
BMI, or Body Mass Index, is a simple calculation based on your height and weight:
BMI = weight (kg) ÷ height (m²)
Once calculated, your BMI places you into one of the following categories:
- Underweight: BMI under 18.5
- Healthy weight: BMI between 18.5 and 24.9
- Overweight: BMI between 25 and 29.9
- Obese: BMI of 30 or above
BMI is widely used in general health assessments and GP checkups because it’s fast and easy to calculate. It offers a basic estimate of whether your weight is appropriate for your height and can flag potential health risks associated with being under or overweight.
However, BMI has limitations. It doesn’t differentiate between muscle, fat, and bone, meaning that very muscular people may fall into the “overweight” or “obese” category despite having low body fat. Similarly, older adults with less muscle may appear to have a “normal” BMI even if their fat levels are too high.
What Is Body Fat Percentage?
Body fat percentage is a measure of how much of your total body weight is made up of fat. It provides a far more accurate look at your health than BMI alone, because it tells you how much of your weight is fat as opposed to lean mass (muscle, bone, organs, and water).
Healthy body fat ranges vary by gender and age, but general guidelines are:
- Men: 10–20% is ideal; over 25% is considered high
- Women: 20–30% is ideal; over 35% is considered high
Carrying too much body fat, particularly around the abdomen, is linked to an increased risk of heart disease, type 2 diabetes, high blood pressure, and other serious health issues. That’s why tracking fat percentage, not just weight, is key to understanding your health.
BMI vs Body Fat Percentage: Which One Matters More?
Both BMI and body fat percentage have value, but body fat percentage is typically a more accurate reflection of your health, especially if you’re trying to lose fat or gain muscle.
For example:
- If your BMI is high but your body fat is low, you’re likely fit and muscular (common among athletes).
- If your BMI is in the normal range but your body fat is high, you could be what’s known as “skinny fat”, a condition that still carries health risks like high cholesterol and insulin resistance.
In other words, BMI can be useful, but it should be considered alongside other indicators, especially body fat percentage, lifestyle habits, and family history.
