Waist Size & Belly Fat
One way of measuring whether you are overweight is by checking your waist size. Belly fat is one of the worst kinds of overweight, according to many experts, and exercise won't help alone; you need to lose fat.
People with excessive belly fat not only have fat on the outside, but on the inside too. It can contribute to heart attacks, diabetes, circulatory problems, impotence in men, and has recently been linked to a future risk of dementia.
According to Mayo Clinic, most men should have a waist measurement under 40 inches. and women under 35 inches to avoid health problems. Measure just above the hipbone, without holding your breath, or sucking it in, and without pulling the tape measure tight. Keep the tape level. A lesser waist size is healthier.
Another measurement is the hip to waist ratio. Measure the hip at the widest point, keeping the tape level and loosely firm, not pulled tight. Measure the waist at the smallest point. Divide your hip measurement by your waist measurement. A healthy waist to hip ratio is less than 0.9 for men, and less than 0.8 for women.
