  1. Abbreviations: BMI, body mass index; MRI, magnetic resonance imaging; PUFA, polyunsaturated fatty acid; SFA, saturated fatty acid; VAT, visceral adipose tissue. The presented data are means±the standard error of the mean. P-values are generated from unpaired two sided t-tests. Thirty-five individuals were included compared with 37 in the original study.6 The PUFA group included 10 males and 5 females while the the SFA group included 14 males and 6 females.
