The purpose of this study was to compare weight-discordant siblings in eating in the absence
of hunger, caloric compensation, and the quality of their habitual diet. The investigator
hypothesized that, within families and controlling for age differences, overweight and obese
siblings would show greater eating in the absence of hunger, poorer caloric compensation, and
poorer diet quality (e.g., increased percent of energy from fat and caloric beverages)
compared to normal-weight siblings.
