Continue reading to learn about the pros and cons of using BMI for obesity.
You can measure body fat in various ways and one of the methods is body mass index. It gives a global view of one’s health and predicts the risk of cholesterol, hypertension, joint problems, etc. Moreover, individuals with high BMI have an increased risk of cancer and chronic diseases. Statisticians use the BMI index to know the obesity level of the population to organize targeted prevention campaigns.
