The efficacy of meal replacement programs for weight loss

BACKGROUND: Weight control can help minimize obesity-related complications. The primary goal of this study is to assess the impact of meal replacement programs on weight loss. METHODS: A retrospective chart review study included participants from a diet center (October 2015 to June 2016). Body Mass Index (BMI) calculated at both baseline and follow-up visits. The dietitian subtracted 500 kcal from the patients' daily calorie needs. The meal replacement program consisted of three main meals and three snacks, delivered to patients on a daily basis. RESULTS: Three hundred participants were enrolled in the study, with a mean age of 34.02 years, mainly female, with a mean weight of 95.5 kg, and mean BMI of 36.9 kg/m(2). The mean weight loss for each follow-up period (1, 1-3, and 3-6 months) was approximately 8 kg. At the last visit, mean net weight loss was 17.75 kg, with a mean BMI of 30.1 kg/m(2). Compared to those who lost <= 10 kg, the patients who lost >10 kg were younger (P=0.16), and had higher baseline BMIs (P<0.05). CONCLUSIONS: Meal replacement programs were a successful method for weight loss. Younger participants with higher baseline BMIs were likely to achieve greater weight loss.
