Body Mass Index (BMI) can be maintained by following a healthy diet, reducing calorie intake, and becoming physically active.BMI is determined by dividing the weight (in kilograms) by the square of height (in metres). BMI indicates if the person is underweight or overweight based on his/her height. A high BMI carries the risk of cardiovascular diseases and high blood pressure. While a low BMI can indicate underweight and low blood pressure issues.
