Overweight, obesity, and weight-related problems appear to be on the rise in the United States. Obesity is now defined in terms of fat content rather than in terms of weight alone.
There are many different methods of assessing body fat. Body Mass Index (BMI) is one of the most commonly accepted measures of weight based on height. Body fat percentages more accurately indicate how fat or lean a person is.
Many factors contribute to one’s risk for obesity, including, genetics, setpoint, endocrine influences, psychosocial factors, eating cues, lack of awareness, metabolic changes, lifestyle, and gender. Women often have considerably more difficulty losing weight.
Exercise, dieting, diet pills, and other strategies are used to maintain or lose weight. However, sensible eating behavior and adequate exercise offer the best options.
Eating disorders consist of sever disturbances in eating behaviors, unhealthy efforts to control body weight, and abnormal attitudes about body shape. Anorexia nervosa, bulimia nervosa, and binge eating disorder are the three main disorders. Though prevalent among white women of upper– and middle-class families, eating disorders affect women of all backgrounds as sell as a number of men.
