In the Surgeon General's Report on Nutrition and Health, of the ten leading causes of death in the United States, five are nutrition related. Instead of nutritional deficiencies as seen in the 1940s, the national diet has shifted to dietary excesses and imbalances. Dietary excesses and imbalances are reflected in obesity, a major health problem affecting approximately 30% of the United States' population. Unfortunately, the diet industry is not regulated and, hence, patients have many avenues from which to choose. Many of these leave patients lost and confused as to why they have failed in maintaining their weight loss. It is well documented that the recidivism rate in the obese is high with only 5% maintaining their weight loss after one year. The following is a review of the physician's and dietitian's roles in long-term weight maintenance.
