It has been an accepted practice that the body mass index is the best measure of the health status of an individual. The body mass index of the weight to height ratio. A value between 20 and 25 has generally been accepted as normal value while a value between 25 and 30 is considered as representing an overweight individual. A BMI above 30 indicates obesity. BMI values of over 40 are indicative of severe obesity. Thus, a high BMI value is considered as a risk factor for several diseases including coronary heart disease. Usually, an increase in BMI is accompanied by an increase in the amount of fat present in the body.
Some recent studies indicate that what is more important than the quantum of fat, is where the fat is present which is more significant as far as the risk for heart disease is concerned. Studies involving heart patients from several countries have shown that it is the fat which is accumulated around the waist and in the abdominal region which is a high risk factor for heart disease. Of course, it is also more difficult to get rid of the belly fat. This fat is rather stubborn and tries to defy all your attempts to get rid of it. Thus, individuals having a smaller waistline and a higher BMI would be having a lowered risk for cardiovascular disease because the fat is uniformly distributed throughout the body. All that is required to assess this risk is a tape to measure the waistline.
Thus, people who are having larger waistlines are in urgent need of weight loss. The additional fat accumulated in the hips and abdominal region is called visceral fat and is considered to be dangerous. The visceral fat is not inert and has been found to be responsible for many of the harmful chemical changes occurring in the body. The visceral fat is metabolically active and releases a large number of chemicals. Some of these chemicals are hormones and are responsible for the changes in the circulating levels of many of the parameters like cholesterol and sugar. These hormones could also be responsible for the onset of hypertension which is a risk factor for heart disease and strokes.
