Final answer:
The best method for assessing visceral fat is by measuring the waist-to-hip ratio. Skin calipers and BMI do not specifically assess visceral fat.
Step-by-step explanation:
The best method for assessing visceral fat is by measuring the waist-to-hip ratio. This measurement involves using a measuring tape to determine the circumference of the waist and hips, and then dividing the waist circumference by the hip circumference. A higher waist-to-hip ratio indicates a greater amount of visceral fat and is associated with increased risks for chronic diseases such as heart attacks. Other methods such as skin calipers and BMI do not specifically assess visceral fat and may not provide an accurate indication of disease risk.
