Brief Summary
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.

EXPERIMENTALInterventions
In a crossover design, siblings were served dinner once a week for 3 weeks. Across conditions, siblings were served the same dinner, but, 25 minutes before dinner, they either consumed in full or did not consume one of two preloads that varied in energy density. On the day when no preload was consumed, eating in the absence of hunger was assessed after dinner and defined as the number of calories consumed from snacks. Habitual dietary intake was assessed using 24-hour dietary recalls.
