Evaluation of commercial packages on the effectiveness of weight loss

The purpose of this study was to assess the effect of commercially packaged interventions on weight control, body composition and blood lipid profiles. One group used commercial package provided by company A (group A), while the other used the package provided by company B (group B). Commercial packages of both groups were used to replace two meals, and total energy intake was 1200 kcal/day for 6 weeks. Group A (n = 30, male = 5; female = 25) and group B (n = 30, male = 8; female = 22) were aged 35 ± 8.9 and 39 ± 9.6 years, with body weights of 75.9 ± 7.67 and 87.3 ± 12.37 kg, and a BMI of 29.2 ± 2.65 and 2.7 ± 4.19 kg/m², respectively. The average weight loss in both groups was 0.68 kg/week. After 6 weeks, waist and hip measurements had significantly decreased (p < 0.05), and the waist-hip ratio and body fat percentage showed significant differences in group B (p < 0.05); triceps skinfold thickness had mildly decreased in both groups, but there were no significant differences; and serum total cholesterol, triglycerides, LDL, and HDL concentrations had significantly decreased in both groups (p < 0.05). For the duration of using these commercial packages, no subjects had any side effects. Therefore, subjects experienced effective weight loss after using the commercial packages in these programs.
