BMI vs Body CompositionMar 09, 2018 / By Bodyfuelz
A lot of people tend to confuse the terms BMI (Body Mass Index) and Body composition. While both are indicators of body fat, they are different in a lot of ways. Let us see what sets them apart.
Body Mass Index (BMI) is an indicator of healthy body weight and is based on your height and weight. It is calculated by dividing your body weight (kgs) by the square of your height (metres). This tells you if you are underweight, normal, overweight or obese.
BMI is a good measure for checking if your body weight is healthy or not. However, BMI isn’t the best measure for everyone. There could be skinny people with a lot of belly fat. For instance, an obese person and a bodybuilder have a BMI of 31. The obese person has high amounts of fat in the body but the bodybuilder has lean and muscle mass which has resulted in a high BMI – it doesn’t mean that the body builder has an unhealthy body weight.
Body composition is a measure of fat, bone, water and muscle in the body. Measuring the body composition gives a better insight of a healthy body weight over BMI. It also tells you how much of your body weight comes from muscle and fat. A “skinny fat” person with a lot of belly fat would have an ideal BMI but according to their body composition, are at a risk of obesity. A bodybuilder with a BMI of 31 would have a healthy body composition because of their high lean mass and low fat levels.
Body composition gives a better insight into healthy body weight over BMI. To maintain a good body composition, have a well balanced diet and exercise. Follow a healthy lifestyle to improve immunity and keep diseases at bay!
