Why is belly fat dangerous to your health?
A small amount of fat is an essential part of a healthy lifestyle. However, having a large amount of belly fat raises the risk of high blood pressure, heart disease, diabetes, and liver problems. Moreover, excess belly fat can be dangerous because it surrounds internal organs and puts you at greater risk for developing several kinds of health problems.
