The 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.
