The present invention provides a device for increasing portion control in a diet. In one illustrative embodiment, the portion control device includes a cover member sized to cover at least a portion of an eating surface of a plate. The cover member may include a first surface having one or more openings therein defined by an opening perimeter. One or more compartment walls may be attached to the first surface adjacent to the perimeter of the one or more openings and may extend a distance therefrom. The openings and the compartment walls may define a portion compartment that may help to manage, and in some cases, measure, portions of food. Additionally, in some embodiments, the compartments may have labels indicating the food group to be placed therein to help achieve a balanced diet.
