4.1. Methylation Analyzed in Blood Samples Showing Association with the BMI
Thirty-four CpG sites for the MHP diet and twenty CpG sites for the LF diet were identified in blood and were associated with the percentage of BMI loss. This relationship of methylation sites with BMI has been observed in previous studies, such as in a clinical trial in a multiethnic Asian population that identified the methylation of 116 CpG sites associated with BMI and the methylation of 8 CpG sites that were associated with waist circumference [
