Weight Loss Effects of an LCHF Diet. A Statistical Meta-Analysis of Meta-Analyses

Research Paper (postgraduate) from the year 2017 in the subject Health - Miscellaneous, grade: 4.0, , course: DHSC9055 Applied Research Project, language: English, abstract: Given the existing problem of obesity, the purpose of this statistical meta-analysis was to measure the weight-loss effectiveness of LCHF diets. Using Cohen s d as the measure, it was found that the mean effect size for LCHF diets was higher (M = 0.5333, SD = 0.29209) than the mean effect size for non-LCHF diets at an Alpha of 0.10, p = 0.058. Additionally, it was found that the mean effect size for LCHF diets (M = 0.5333, SD = 0.29209) in comparison to control (non-diet) groups (M = 0.0358, SD = 0.03470), p < 0.001 was also higher. These findings provide empirical support for the claim that LCHF diets are effective, both in isolation and in comparison to other dietary interventions.
