Body index mass, otherwise known as Body Mass Index or BMI is a formula that calculates body fat percentage based on height and weight. It does not directly measure body fat, but rather approximates it using an equation. BMI may be used to evaluate if a person is overweight or healthy.
A high BMI indicates that the body has too much fat, whereas a low BMI indicates that the body has too little fat. The higher a person’s BMI, the more likely they are to acquire significant health problems including heart disease, high blood pressure, and diabetes. A low BMI can lead to health issues such as bone loss, impaired immunological function, and anaemia.
While BMI can be effective in detecting body weight concerns in children and adults, it does have its limitations. In athletes and other persons with exceptionally muscular bodies, BMI may exaggerate the amount of body fat. It may also underestimate body fat in elderly folks and those who have lost muscular mass.
