In a paragraph, summarize the article overall.What two things did you learn from this article?After reading this article, what would you tell someone who eats a poor diet and has some of the risk factors for overweight and obesity? Do you think cultural differences can contribute to what foods are habitually eaten?Americans are eating “junk” food such as fast food, cookies, and chips in place of fruits, vegetables, whole grains, and lean meats. How, in your opinion, are fast food or junk food items linked to diseases? Can these foods compromise your nutritional status? Is there a way to measure if junk foods may be negatively affecting your health?
Over two-thirds of adults in the United States are overweight or obese, and over one-third are obese, according to data from the National Health and Nutrition Examination Survey (NHANES) 2003–2006 and 2007–2008.
What Are Overweight and Obesity?
Overweight: Overweight specifically refers to an excessive amount of body weight that may come from muscles, bone, adipose (fat) tissue, and water.
Obesity: Obesity specifically refers to an excessive amount of adipose tissue.1
Causes of Overweight and Obesity
Essentially, overweight and obesity result from energy imbalance. The body needs a certain amount of energy (calories) from food to sustain basic life functions. Body weight is maintained when calories eaten equals the number of calories the body expends, or “burns.” When more calories are consumed than burned, energy balance is tipped toward weight gain, overweight, and obesity. Genetic, environmental, behavioral, and socioeconomic factors can all lead to overweight and obesity.2
Treating Overweight and Obesity
Overweight and obesity are risk factors for diabetes, heart disease, high blood pressure, and other health problems. Since there is no single cause of all overweight and obesity, there is no single way to prevent or treat overweight and obesity that will help everyone. Treatment may include a combination of diet, exercise, behavior modification, and sometimes weight-loss drugs. In some cases of extreme obesity, bariatric surgery may be recommended.2
Risk Factors for Overweight and Obesity
■ type 2 diabetes
■ coronary heart disease
■ high LDL (“bad”) cholesterol
■ stroke
■ hypertension
■ nonalcoholic fatty liver disease
■ gallbladder disease
■ osteoarthritis (degeneration of cartilage and bone of joints)
■ sleep apnea and other breathing problems
■ some forms of cancer (breast, colorectal, endometrial, and kidney)
■ complications of pregnancy
■ menstrual irregularities
Estimates on Overweight and Obesity
The estimates on overweight and obesity in this fact sheet were taken from the Centers for Disease Control and Prevention (CDC). Data are based on the CDC’s National Health and Nutrition Examination Survey (NHANES) from 2003–2006 and 2007–2008.
Some of the overweight- and obesity-related prevalence rates are presented as crude or unadjusted estimates, while others are age-adjusted estimates. Unadjusted prevalence estimates are used to present cross-sectional data for population groups at a given point or time period, without accounting for the effect of different age distributions among groups. For age-adjusted rates, statistical procedures are used to remove the effect of age differences when comparing two or more populations at one point in time, or one population at two or more points in time. Unadjusted estimates and age-adjusted estimates will yield slightly different values. Overweight And Obesity Assignment
Unless otherwise specified, the figures below represent age-adjusted estimates. Age-adjusted estimates are used in order to account for age variations among the groups being compared.

Overweight and Obesity Prevalence Estimates*
Q: How many adults age 20 and older are overweight or obese (Body Mass Index, or BMI, ≥ 25)?
A: Over two-thirds of U.S. adults are overweight or obese.4
All Adults 68 percent Women 64.1 percent Men 72.3 percent
Q: How many adults age 20 and older are obese (BMI ≥ 30)?
A: Over one-third of U.S. adults are obese.4
All Adults 33.8 percent Women 35.5 percent Men 32.2 percent
Q: How many adults age 20 and older are extremely obese (BMI ≥ 40)?
A: A small percentage of U.S. adults are extremely obese.4
All Adults 5.7 percent
Q: How many adults age 20 and older are at a healthy weight (BMI ≥ 18.5 to < 25)?
A: Less than one-third of U.S. adults are at a healthy weight.5
All Adults 31.6 percent Women 36.5 percent Men 26.6 percent
Q: How has the prevalence of obesity in adults changed over the years?
A: The prevalence has steadily increased among both genders, all ages, all racial/ethnic groups, all educational levels, and all smoking levels.6 From 1960–2 to 2005–6, the prevalence of obesity increased from 13.4 to 35.1 percent in U.S. adults age 20 to 74.7 Since 2004, while the prevalence of overweight is still high among men and women, there are no significant differences in prevalence rates documented from 2003 to 2004, 2005 to 2006, and 2007 to 2008.4 In fact, among women, there has been no change in obesity prevalence between 1999 and 2008.
Q: What is the prevalence of obesity among non- Hispanic Black, Hispanic, and non-Hispanic White racial and ethnic groups?
A: Among women, the age-adjusted prevalence of obesity (BMI ≥ 30) in racial and ethnic groups is higher among non-Hispanic Black and Hispanic women than among non-Hispanic White women. Among these three groups of men, the difference in prevalence is less significant. In this context, the term Hispanic includes Mexican Americans.4 Overweight And Obesity Assignment
