Eating Frequency Study

Completed · Not applicable

Conditions studied: Eating Frequency

In brief

The purpose of this study is to examine the influence of two Eating Frequency prescriptions, meal (energy intake occurring during three meals per day) and grazing (energy intake occurring every two to three hours per day), on consumption during an ad libitum meal consumed at the end of the day, overall daily energy intake, and ratio of energy intake to energy expenditure. It is hypothesized that the grazing condition will produce lower consumption during an evening ad libitum meal, lower daily energy intake, and a lower ratio of energy intake to energy expenditure than the meal condition.
