In contrast , changes in fasting and 2-h insulin ( -3.4 mUl ( -1 ) , P = 0.035 and -26.6 , P = 0.003 , respectively ) , homeostasis model assessment-estimated insulin resistance ( -1.0 , P = 0.036 ) , total cholesterol ( -0.55 mmoll ( -1 ) , P = 0.041 ) , low-density lipoprotein ( LDL ) cholesterol ( -0.36 mmoll ( -1 ) , P = 0.008 ) and visceral fat area ( -5.5 cm ( 2 ) , P = 0.030 ) were significantly greater in the intervention than in control subjects .
