Define overweight and obesity, and determine how much you should weigh. Recognize risks of being obese. Describe how to use the following components of a weight loss program to lose weight: eating plan, exercise, behavior and attitude modification, and support. Introduction to Weight Management Overweight and obesity are among the most pressing challenges in the United States. In 2010, 18 percent of children ages 6 to 19 were obese. In the 1970s, only 4 to 6 percent were obese. More than double the number of adults were obese in 2010 when compared to the 1970s. What Is Kcalorie Balance? Kcalorie balance refers to the relationship between the kcalories you take in from food and beverages and the kcalories you use through physical activity and your basal metabolism. If kcalories consumed = kcalories used, then you maintain the same body weight. If you eat fewer kcalories than you use, then you lose weight. If you eat more kcalories than you use, then you gain weight. Factors that play a role in obesity: Behavioral—choices you make in eating and exercise Cultural Socioeconomic Genetics Other diseases/conditions Environmental Increase in portion sizes Limited access to healthy affordable foods Lack of safe places to be active Greater availability of high kcalorie foods How Much Should I Weigh?
