Computer-assisted dieting: effects of a randomized nutrition intervention.

OBJECTIVES To compare the effects of a computer-assisted dieting intervention (CAD) with and without self-management training on dieting among 55 overweight and obese adults. METHODS Random assignment to a single-session nutrition intervention (CAD-only) or a combined CAD plus self-management group intervention (CAD+G). Dependent variables were the number of servings from various food groups and macronutrients related to body weight. RESULTS Both intervention groups reduced the consumption of energy, fat, and carbohydrates. Relative to CAD-only, the CAD+G condition was more successful in reducing fat intake, increasing vegetable consumption, and maintaining fruit intake. CONCLUSIONS Effects of computer-assisted self-monitoring can be augmented through self-management training.
