No one has ever said to a dietitian "Gee I did not realize eating an entire cheese cake would make me fat." It is astounding new diets continue to claim to be the answer to permanent weight loss assuming no one knows that what they are eating and the amounts they are eating is not working. This is a continual attack on the body to try to change the mind.
As with every other issue in life weight loss is about getting control one's emotional state via the the subconscious. Until this approach is taken one will not be able to accomplish a permanent change with anything, let alone a permanent weight loss. Permanent weight loss is all about control of your emotional state and eating behavior.
Below are some frequently asked questions and answers about overweight and obesity statistics. Data are based on NHANES 2001 to 2004. Unless otherwise specified, the figures given represent age-adjusted estimates. Age-adjusted estimates are used in order to account for the age variations among the groups being compared. Population numbers are based on estimates from the U.S. Census Bureau’s Current Population Survey.
Q: How many adults age 20 and older are overweight or obese (BMI > 25)?
A: About two-thirds of U.S. adults are overweight or obese.
All adults: 133.6 million (66 percent)
Women: 65 million (61.6 percent)
Men: 68.3 million (70.5 percent)
* The statistics presented here are based on the following definitions unless otherwise specified: healthy weight = BMI > 18.5 to < 25; overweight = BMI > 25 to < 30; obesity = BMI > 30; and extreme obesity = BMI > 40.
Q: How many adults age 20 and older are obese (BMI > 30)?
A: Nearly one-third of U.S. adults are obese.
All adults: 63.6 million (31.4 percent)
Women: 35 million (33.2 percent)
Men: 28.6 million (29.5 percent)
Q: How many adults age 20 and older are at a healthy weight (BMI > 18.5 through 24.9)?
A: Less than one-third of U.S. adults are at a healthy weight.
All adults: 65.4 million (32.3 percent)
Women: 38.1 million (36.1 percent)
Men: 27.4 million (28.3 percent)
Q: How has the prevalence of overweight and obesity in adults changed over the years?
A: The prevalence has steadily increased over the years among both genders, all ages, all racial and ethnic groups, all educational levels, and all smoking levels. From 1960 to 2004, the prevalence of overweight increased from 44.8 to 66 percent in U.S. adults age 20 to 74. The prevalence of obesity during this same time period more than doubled among adults age 20 to 74 from 13.3 to 32.1 percent, with most of this rise occurring since 1980.
Q: What is the prevalence of overweight or obesity in minorities?
A: Among women, the age-adjusted prevalence of overweight or obesity (BMI > 25) in racial and ethnic minorities is higher among non-Hispanic Black and Mexican-American women than among non-Hispanic White women. Among men, there is little difference in prevalence among these three groups . Sufficient data for other racial and ethnic minorities has not yet been collected.
Non-Hispanic Black Women: 79.6 percent
Mexican-American Women: 73 percent
Non-Hispanic White Women: 57.6 percent
Non-Hispanic Black Men: 67 percent
Mexican-American Men: 74.6 percent
Non-Hispanic White Men: 71 percent
(Statistics are for populations age 20 and older.)
Studies using this definition of overweight and obesity provide ethnicity-specific data only for these three racial and ethnic groups. Studies using different BMI cutoff points derived from NHANES II data to define overweight and obesity have reported a high prevalence of overweight and obesity among Hispanics and American Indians. The prevalence of overweight and obesity in Asian Americans is lower than in the population as a whole.
Q: What is the prevalence of overweight and obesity in children and adolescents?
A: While there is no generally accepted definition for obesity as distinct from overweight in children and adolescents, the prevalence of overweight* is increasing for children and adolescents in the United States. Approximately 17.5 percent of children (age 6 to 11) and 17 percent of adolescents (age 12 to 19) were overweight in 2001 to 2004.
* Overweight is defined by the sex- and age-specific 95th percentile cutoff points of the 2000 CDC growth charts. These revised growth charts incorporate smoothed BMI percentiles and are based on data from NHES II (1963 to 1965) and III (1966 to 1970), and NHANES I (1971 to 1974), II (1976 to 1980), and III (1988 to 1994). The CDC BMI growth charts specifically excluded NHANES III data for children older than 6 years.

Q: What is the mortality rate associated with obesity?
A: Most studies show an increase in mortality rates associated with obesity. Individuals who are obese have a 10- to 50-percent increased risk of death from all causes, compared with healthy weight individuals (BMI 18.5 to 24.9). Most of the increased risk is due to cardiovascular causes. Obesity is associated with about 112,000 excess deaths per year in the U.S. population relative to healthy weight individuals.
