Abstract

A behavioral intervention with a low-energy diet including 5 meal replacements and 5 servings of fruits or vegetables enabled obese individuals to lose 13 kg more than control subjects over a 24-week period.

A Systematic Review of Literature on the Effectiveness of Behavioral Weight Loss Programs to Achieve Weight Reduction

“…This comprehensive literature review yielded three randomized control trials [9][10][11] that looked at how dietary counseling and meal replacements within the HMR behavioral weight loss program compared to subjects receiving no dietary counseling or meal replacements.

“…Two of the studies, Anderson et al in 2011 [11] and Anderson et al in 2007 [7], found positive reduction in certain laboratory findings associated with comorbidities including cholesterol, triglyceride, glucose, and blood pressure. Studies from Rohrer et al [3], Anderson et al [11], and Smith et al [10] showed that patients receiving weekly outside support achieved better weight loss results than those receiving no outside support. Anderson et al [7] found that men lost weight quicker than women but overall weight loss percentage was the same.…”

“…Characteristics for both groups were similar with the average age of all patients of 46, 76% of the patients were female, and initial BMI average was 35. Control group members met with a registered dietician and received instructions designed to achieve 10% weight loss over six months and attended follow up meetings every eight weeks [11]. MR-FV group members were placed on a 1200 kcal diet including two entrees, three shakes, and five servings of fruits and vegetables.…”
