The most trustworthy weight charts for both men and women are available online through websites such as WebMD and CDC.gov. Calculating BMI and muscle-to-fat ratios are different ways to determine your level of fitness and health.
BMI, or body mass index, is a number calculated using a person’s height and weight. For the average person, BMI is a good indicator as to whether or not his is overweight.
BMI scales are broken up into four categories: underweight, healthy weight, overweight and obese. Websites such as WebMD have reliable BMI calculators to tell you where your weight falls on the scale of overall health.
Some body types do not fit into the BMI scale correctly, including, but not limited to, bodybuilders and athletes. For irregular body types, it is better to calculate the muscle-to-fat ratio. The simpler calculation is to use a website that measures height, weight, neck and hip diameters for an approximation. This is known as the U.S. Navy Body Fat Percentage Formula.
It is also possible to visit a licensed health adviser, such as a nutritionist or personal trainer, who can physically measure your body fat with a tool called a skinfold caliper. The skinfold caliper is the most accurate way to measure your body fat percentage.
