Moderate weight loss: a self-directed protocol for women.
This innovative, self-directed diet and physical activity program was designed to achieve moderate weight loss in women. Thirty-five overweight or obese hyperlipidemic women completed a 20-week weight loss study. The weight loss intervention consisted of a 20% decrease in energy intake through diet and a 10% increase in energy expenditure through physical activity. The diet consisted of 50-60% carbohydrates, 20% protein, and 20-30% fat. A personal trainer prescribed physical activity regimens. A progress-tracking system and monthly group sessions were used to maintain participant motivation throughout the weight loss period. Participants lost an average of 11.7 +/- 2.5 kg (p<0.001). The pattern of weight loss was linear (p<0.001) throughout the study period. Average weight loss per week was 0.59 +/- 0.55 kg. This 20-week program, combining a structured self-selected diet and independent preplanned physical activity with motivational strategies, resulted in weight loss comparable to that observed in more controlled interventions. The lower cost, ease of use, and outcome success make this approach potentially useful in a clinical setting.
