Role of food characteristics in behavioral change and weight loss.

A behaviorally oriented correspondence course was completed by 517 subjects. All subjects received the behavioral course but were sorted into four groups: (a) behavioral instruction only, (b) recommend soup for lunch, (c) recommend soup for any meal or snack, and (d) recommend yogurt for meals or snacks. Subjects lost an average of 3.8 kg. in 10 weeks. There was a marked association between rate of eating and total caloric consumption for the meal. Eating soup as part of lunch or dinner led to both decreased consumption of kilo-calories and a slower rate of eating.

Changes in nutrient intake during a behavioral weight control program.

Behavioral modification holds promise of being an effective mode of therapy for obesity. It focuses on changing clients' eating habits and does not always include specific dietary guidance. This study was conducted to learn whether such behavior modification training results in the adoption of nutritionally sound dietary patterns. Originally, the diets of fifteen individuals met two-thirds of all Recommended Dietary Allowances. After a twenty-week program, the only nutrients below this level were iron, thiamin, and calcium. Other changes involved an increase in nutrient density for protein, fiber, phosphorus, iron, vitamin A, thiamin, riboflavin, niacin, ascorbic acid, and cholesterol. Nutrient density for carbohydrates, fat, and calcium decreased.

Managing obesity: why diet is not enough.

When the many biologic and societal factors predisposing persons to obesity are considered, it is understandable why traditional therapy so often fails. To be effective, a program of therapy for obesity must include necessary changes in behavior, attitude, and life-style; dieting is not enough. As a first step, the determinants of past and present behaviors contributing to high energy intake, low energy expenditure, or both are identified. Once this is done, therapy is directed toward altering exposure, susceptibility, or response to these determinants.
