Dietary Guidelines 2005: Weight Management AdviceThe latest weight control advice from the US government, as set out in the 2005 Dietary Guidelines, emphasises the link between (1) excessive calorie-intake in the average American diet combined with lack of physical exercise, and (2) chronic diseases, like obesity, diabetes and cardiovascular disorders. Excessive Diet Calories and Lack of ExerciseWeight management involves eating fewer calories while increasing physical exercise. For the first time, the new dietary guidelines emphasises the need for calorie control and increased fitness. The main reason for this is the huge increase in overweight. Effects of Obesity on HealthObesity and overweight have reached epidemic levels in the United States. The prevalence of obesity has doubled in the past 20 years. Of special concern is the rise in the number of obese individuals with accompanying comorbidities. Over the last 20 years, the overweight among children and teens has risen significantly. Almost 9 million young Americans, or an estimated 16 percent of children and teenagers are overweight, twice the rate among children and three times the rate among teens. The surge in obesity has triggered a significant rise in weight-related disease. For example, among American adults, diagnosed type 2 diabetes increased 49 percent from 1990 to 2000. In addition, excessive body fat (especially abdominal fat) leads to increased risk of high blood pressure, dyslipidemia, heart disease, stroke, gall bladder disease, breathing problems, arthritis, certain kinds of cancers and even premature death. Healthy Weight GoalsThe goal for adults is to attain and maintain a body weight that optimizes their health. There is no ideal weight, though there is a healthy weight range. For obese people, even small weight loss (e.g. 10 pounds, or 5 percent of initial weight) has health benefits, and the prevention of further weight gain is crucial. The goal for overweight children and teens is to reduce the rate of weight gain without interfering with normal development. |
