Breakfast

The most important meal of the day, unless it is a donut.

What's "unique" about the current study is that it suggests that breakfast foods low in "energy density" -- low in calories for a given amount of food -- "appear to predict better food choices for the rest of the day and may help with better management of body weight," Dr. James Rippe, one of the researchers on the work, said in a written statement.

Fruits, vegetables and high-fiber whole grains, for example, are low in energy density, while confections like Danish pastries and doughnuts have a high energy density.

Essentially, if you make healthy choices at breakfast, you will make healthy choices during the rest of the day. Truly revolutionary.
