Excess weight around the waist = increased risk of disease

Here's a message from the National Institute of Diabetics and Digestive and Kidney Diseases that may prompt you to incorporate a healthy diet:

Where excess fat is located on your body may be another risk. If you carry fat mainly around your waist, you are more likely to develop health problems than if you carry fat mainly in your hips and thighs. This is true even if your BMI falls within the normal range. Women with a waist measurement of more than 35 inches or men with a waist measurement of more than 40 inches may have a higher disease risk than people with smaller waist measurements because of where their fat lies.
