Huerta S, Li Z, Li HC, Hu MS, Yu CA, Heber D. Int J Obes. 2004;28(12):1575-1579.

Objective

To evaluate the effectiveness of a Slim•Fast meal replacement on weight loss in low-income, obese patients (BMI>40 kg/mm2) over a 6-month period compared with routine medical care provided by primary care physicians (PCP).

Methods

In this prospective study, 63 patients who had been followed for 6 months or longer by their primary care physician (PCP), were referred to a nutrition clinic where they were instructed to consume 2 Slim•Fast meal replacements and one portion-controlled meal for a 6-month period. Patients had the opportunity to meet with dietitians and were counseled on low-fat, low carbohydrate diets and exercise. Data were analyzed at baseline, 1, 3, and 6 months, and compared to retrospective data covering the same time interval.

Results

No changes in weight at 1, 3 or 6 months were noted prior to implementation of the nutrition clinic. After implementation of the nutrition program, there was a trend toward a decrease in BMI at 1 and 3 months. At 6 months, there was a 7.5% decrease in BMI compared to baseline. A significant percentage of patients (32%) were able to lose 5-10% body weight at 6 months compared to baseline. Twenty-two percent of patients were able to lose more than 10% of body weight.

Conclusion

Slim•Fast meal replacements provide a practical, economical and effective approach to weight management for the obese, low-income patient population.
