Smokers and subjects with prescribed medication, except for contraceptives, and excessive weight loss during the last 3 months were excluded from participating in this study. The subjects were paid for their involvement and informed consent was obtained according to the guidelines of the Ethical Committee of Wageningen UR. Weight, height, and waist and hip circumferences, were measured while subjects wore light indoor clothing with emptied pockets and no shoes. To estimate body weight, 1 kg was subtracted from clothed body weight. Body mass index (BMI) was the weight divided by height squared. Waist circumference was measured at the level midway between the lower rib margin and the iliac crest, with participants in a standing position and breathing out gently. Hip circumference was measured at the level of the widest circumference over the greater trochanters. The waist-to-hip ratio (WHR) was calculated as waist circumference divided by hip circumference.

In this food-related context, these ANS characteristics not only provide additional insights into the integration of central and peripheral regulatory processes for metabolism, but also render a potential measure of satiety in humans. 2001 α 1974 1996 2000 2000 1997 α α α α 1986 α 1997 2000 2005 2002 2004 1991 2000 1999 2004 2003 2004 2005 α
