Data from the 13 subjects who completed the MR investigations. BMI: body mass index, VAT: visceral adipose tissue volume, SAT: subcutaneous adipose tissue volume in the abdominal subvolume, EVF: erythrocyte volume fraction. ALT: alanine transaminase, AST: aspartate aminotransferase, GT: gamma glutamyltransferase, BNP: B-type natriuretic peptide, FFA: free fatty acids.
Statistical significance evaluated from differences in relative changes over the LCD and GBP months.
