1All analyses concerning waist circumference, waist-to-hip ratio, and metabolic variables are adjusted for weight change during the MedDiet. Values are presented as means with their standard errors (SEM). Men and women with a waist circumference of, respectively, >102 cm and >88 cm were considered as having abdominal obesity.
2Analysis was performed on transformed values.
3Calculated as (1/[fasting glucose (mmol/L) × fasting insulin (pmol/L)/22.5]) for measuring insulin sensitivity.
*Abdominally obese individuals significantly decrease their waist circumference in response to the MedDiet, .
