Pressure (symbol: p or P) is the force applied perpendicular to the surface of an object per unit area over which that force is distributed. Gauge pressure (also spelled gage pressure) is the pressure relative to the local atmospheric or ambient pressure. Various units are used to express pressure.
A BMI of 25 to 29.9 indicates a person is overweight. A person with a BMI of 30 or higher is considered obese. Like the weight-to-height table, BMI does not show the difference between excess fat and muscle. BMI, however, is closely associated with measures of body fat. It also predicts the development of health problems related to excess weight.
People with a body mass index (BMI) of 30 or higher are considered obese. The term âobesityâ is used to describe the health condition of anyone significantly above his or her ideal healthy weight. Donât be discouraged by the term. It simply means you are 20% or more above your ideal weight, and you are not alone. Nearly 70% of American adults are either overweight or obese.
