Table 3 Shows BMI, fat mass, free fat mass, phase angle, and intracellular and extracellular water at the baseline and after three months of each diet. The results for chronic and high-frequency migraineurs in each group are also presented. There was a significant reduction in BMI and fat mass in both groups. A paired t-test or a wilcoxon test was used to compare; significance was determined with a p-value of 0.05
