Values are means ± standard deviations. Visual analog scale ratings of hunger, fullness and willingness to eat were obtained immediately prior to the ad libitum buffet and are measured in millimeters (mm). All DZ twin pairs were complete. MZ: monozygotic; DZ: dizygotic; BMI: body mass index; kcals: kilocalories. P-values derived from generalized estimating equations.
