1Data represent characteristics of participants after the run-in period.
Men and women with a waist circumference of, respectively, >102 cm and >88 cm were considered as having abdominal obesity. Analyses were performed after adjustment for sex.
Mean values were significantly different between groups before the controlled Mediterranean diet by the General Linear Model procedure; * .
2Analysis was performed on transformed values.
3Calculated as (1/[fasting glucose (mmol/L) × fasting insulin (pmol/L)/22.5]) for measuring insulin sensitivity.
