Myhre R, Kratz M, Goldberg J, Polivy J, Melhorn S, Buchwald D, Cummings DE, Schur EA Genetic, physiological, and psychological factors can affect food intake, but twin studies can distinguish inherited from environmental contributors. We examined the influence of attempted cognitive control of eating (“restrained eating”) on levels of appetite-regulating hormones. Sixteen female, monozygotic twin pairs, […]

Schur EA, Kleinhans NM, Goldberg J, Buchwald DS, Polivy J, Del Parigi A, Maravilla KR We studied whether self-reported intent to exert cognitive control over eating was associated with differences in brain response to food cues, independent of genetic background. Subjects were ten pairs of identical twins in which one twin was a restrained eater […]

Schur E, Noonan C, Polivy J, Goldberg J, Buchwald D We examined the relative contributions of genetic and environmental influences to restrained eating. Restrained eating was assessed by the Restraint Scale in a survey mailed to all twins enrolled in the University of Washington Twin Registry. We used structural equation modeling to estimate genetic and non-genetic […]
