HEALTHY WEIGHTS

Am I the right weight for my height?

"Are you at a healthy weight? Measure your body mass index and waist hip ratio. Find out what the terms healthy weight, overweight, and obese really mean." http://www.cdc.gov/nccdphp/dnpa/obesity/basics.htm

Obesity is defined as an excessively high amount of body fat compared to lean body mass (muscle, bones, organs and other tissues). Where you wear this excess body fat (or adiposity) as well as how much excess body fat you have are both of concern. Regardless of where you are carrying this excess fat, it is putting a strain on your heart and joints, as well as increasing your risk of disease, including diabetes, heart disease and cancer.

Overweight refers to increased body weight in relation to height, when compared to some standard of acceptable or desirable weights. Overweight may or may not be due to increases in body fat. For example, professional athletes may be very lean and muscular, with very little body fat, yet they may weigh more than others their same height simply because of their larger muscle mass. While they may qualify as "overweight," they are not necessarily "over fat."

So how do you measure your body fat?
Body fat and it's distribution can be estimated by skinfold measures, underwayer weighing, bioelectrical impedance, or by techniques such as ultrasound, computed tomography, or magnetic resonance imaging. The majority of these tests require expensive equipment and highly skilled technicians. Because of this scientists have developed simple tools that you can use in the privacy of your own home to help you determine if you are in a healthy weight range for your body (BMI) as well as how you carry your fat (WC and WHR)

Body Mass Index (BMI) is a common measure expressing the relationship (or ratio) of your bodyweight-to-height. BMI is a mathematical formula in which a person's body weight in kilograms is divided by the square of his or her height in meters (i.e., wt/(ht)2. The BMI is more highly correlated with body fat than any other indicator of height and weight.

Individuals with a BMI of 25 to 29.9 are considered overweight, while individuals with a BMI of 30 or more are considered obese.

Waist circumference is a common measure used to assess abdominal fat content. The presence of excess body fat in tummy area, when out of proportion to total body fat, is considered an independent predictor of other health problems associated with obesity.

What waist size is risky?

  • Men at risk have a waist measurement greater than 40 inches (102 cm) - this could be in the form of love handles that one can grab OR that "hard as rock" tummy that looks like it has a basketball pushing it out. These are the guys that do their belts up at their hips and insist that they still have a 34" waist.......

  • Women at risk have a waist measurement greater than 35 inches (88 cm)

Waist-to-hip ratio (WHR) is the ratio of a person's waist circumference to hip circumference, mathematically calculated as the waist circumference divided by the hip circumference. For most people, carrying extra weight around their middle increases health risks more than carrying extra weight around their hips or thighs. (NOTE: Overall obesity is still more risky than body fat storage locations or waist-to-hip ratio.)

What waist-to-hip ratio is considered risky?
For both men and women, a waist-to-hip ratio of 1.0 or higher is considered "at risk" or in the danger zone for undesirable health consequences, such as heart disease and other ailments connected with being overweight.

What is a good waist-to-hip ratio?
For men, a ratio of .90 or less is considered safe. This means that your waist is 90% of your hips...so you can do your belt up tighter around your waist than your hips.
For women, a ratio of .80 or less is considered safe. Women tend to have more of a "curvy" figure so our waist should be 80% of our hips.

How to measure waist circumference:
With a tape measure, comfortably measure the distance around the smallest area below the rib cage and above the umbilicus (belly button).

How to measure hip circumference:
With a tape measure, comfortably measure the distance around the largest extension of the buttocks.
