Overweight body mass index

Testing should be considered for persons younger than 45 years of age or more frequently in individuals who are overweight (body mass index greater than or equal to 25 kg/m2) and have additional risk factors ... 

Weight reduction in people who are overweight (body mass index [BMI] over 25 kg/m2)... 

Overweight (body mass index [BMI] >25 kg/m ) and obesity (BMI >30 kg/m ) are associated with increased risk for many of the most common cancers. Epidemiological and preclinical (animal and cell culture) studies indicate that increased consumption of fruits, vegetables, and whole grains is associated with reduced cancer risk. Alcohol consumption has been associated with an increased risk of some cancers. Many bioactive food components can simultaneously influence multiple sites involved in the cancer process. 

Obesity is defined by the body mass index (BMI), measured as body weight in kilograms divided by the squared height in metres (kg/m2). A BMI of 30 or more is a commonly-used criterion for defining obesity and a BMI between 25 and 30 is considered overweight. 

Body mass index (BMI), waist circumference, comorbidities, and readiness to lose weight are used in the assessment of the overweight or obese patient.

The body mass index (BMI) is a number calculated from a person s weight and height that can be used to estimate his or her level of body fat. A person is classified as healthy, overweight, or obese based on his or her BMI. The BMI value can be helpful in assessing the health risks a person may face because he or she is carrying too much weight. 

The Body Mass Index (BMI) is used to determine whether a person is at a healthy weight, overweight or obese. BMI has some limitations, in that it can overestimate body fat in people who are very muscular and it can underestimate body fat in people who have lost muscle mass, such as many elderly. 

Figure 1.1 The body mass index (BMI) is a formula that calculates whether a person is an ideal body weight, overweight, or obese. The formula used to calculate BMI considers a person s weight and height. BMI has some limitations. It may not be accurate for people who are very muscular, such as bodybuilders, and people with very little muscle mass, such as the elderly. BMI is one of several factors health-care providers consider when they determine whether a person is overweight or obese. Note that this BMI chart is designed for adults who are age 20 or older.

Body mass index (BMI) is another index of weight-for-height that is highly correlated with body fat. Interpretation of BMI should include consideration of gender, frame size, and age. BMI values greater than 25 kg/m2 are indicative of overweight, and values less than 18.5 kg/m2 are indicative of undernutrition. BMI is calculated as follows ... 

The body mass index, BMl, is the most rehable measure of overweight and obesity. 

Nearly two-thirds of Americans are classified as overweight according to the criteria of body mass index (BMI) calculations, and obesity is now considered to be a disease. 

The body mass index (BMI) is a measure of body fat. It is calculated in both men and women as the (weight in kg)/(height in inches2). Individuals with a BMI between 25.1 and 29 are considered overweight, and those with a BMI greater than 30 are defined as obese.

In industrialized nations, a significant portion of the population is overweight. The Body-Mass-Index (BMI) provides a reliable and simple quantitative criterion for assessing this condition it is calculated as follows ... 

Those who are overweight should reduce their total caloric intake, ideally until they have returned to the weight that is appropriate for their height (i.e. body mass index) but realistically with an initial aim of reducing body weight by 10% (see Appetite control p. 696) this automatically assumes reduced intake of alcohol and total (especially animal) fat. Elevated triglyceride concentrations may respond particularly well to alcohol withdrawal.
