Abstract
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. Given the increasing incidence of overweight and obesity along with the
escalating health care costs associated with weight-related illnesses, health care
providers must discover how to effectively treat this complex condition. Food and
nutrition professionals should stay current and skilled in weight management to assist
clients in preventing weight gain, optimizing individual weight loss interventions,
and achieving long-term weight loss maintenance. Using the American Dietetic Association's
Evidence Analysis Process and Evidence Analysis Library, this position paper presents
the current data and recommendations for weight management. The evidence supporting
the value of portion control, eating frequency, meal replacements, and very-low-energy
diets are discussed as well as physical activity, behavior therapy, pharmacotherapy,
and surgery. Public policy changes to create environments that can assist all populations
to achieve and sustain healthful lifestyle behaviors are also reviewed.
