Position of the American Dietetic Association: Weight management

Obesity has reached epidemic proportions in the United States and health-care costs associated with weight-related illnesses have escalated. While dietetics professionals say lifestyle modifications in food intake and physical activity remain the most effective forms of treatment, many people find them difficult to begin and maintain long-term. Registered dietitians play a vital role in developing weight loss and weight management plans and setting reasonable goals, which can be met by eating a healthful diet.

ADA's position statement is as follows:
It is the position of the American Dietetic Association that successful weight management to improve overall health for adults requires a lifelong commitment to healthful lifestyle behaviors emphasizing sustainable and enjoyable eating practices and daily physical activity.

"Traditionally, the focus of 'diet' has been on weight that is lost," said Chicago-based registered dietitian and ADA spokesperson Dawn Jackson. "But it's now realized that preventing weight gain is just as important. Dietetics professionals should work to help their patients achieve and accept a healthier weight and adopt healthier lifestyles that lead to reducing health risks," said Jackson, nutrition educator at Northwestern Memorial Hospital Wellness Institute.

Variety is the spice of life

The old adage "Variety is the spice of life" is also the recipe for a healthful lifestyle, especially among the elderly, according to researchers at the School of Nutrition Science and Policy at Tufts University. Researchers evaluated frail nursing home residents to see if consuming a varied diet would improve their nutritional health. As part of the study, the researchers looked at weight, height, body mass index, skinfold thickness and muscle mass, as well the participants' medical history. Results showed that elderly nursing home residents who consume a wide variety of foods do experience an improved "nutritional status," and that preventive measures to improve variety, such as increasing available choices and assistance with meals, could be implemented before nutritional complications arise.

"Scientific evidence continues to show eating more fruits, vegetables, legumes and whole grains and selecting nonfat or low-fat dairy products and lean meats are important to good health," said Los Angeles-based registered dietitian and ADA spokesperson Bettye Nowlin. "This research proves that it's never too late to incorporate a variety of foods into an eating plan and get great results," said Nowlin, instructor at Pepperdine University.
