New study reveals higher protein breakfast may help dieters stay on track

Research findings reveal eating more protein in the morning helps dieters retain fullness throughout the day

Lafayette, Ind. (September 3, 2008) - A new study published online today in the British Journal of Nutrition found that timing of dietary protein intake affects feelings of fullness throughout the day. The study concluded that when people ate high-quality protein foods, from sources such as eggs and lean Canadian bacon, for breakfast they had a greater sense of sustained fullness throughout the day compared to when more protein was eaten at lunch or dinner.i

"There is a growing body of research which supports eating high-quality protein foods when dieting to maintain a sense of fullness," said Wayne W. Campbell, PhD, study author and professor of Foods and Nutrition at Purdue University. "This study is particularly unique in that it looked at the timing of protein intake and reveals that when you consume more protein may be a critical piece of the equation."

A Closer Look at the Study
The study included overweight or obese men who ate a reduced calorie diet. The diet consisted of two variations of protein intakes, both which were within federal nutrition recommendations: normal protein intake (11-14 percent of calories) or increased protein (18-25 percent of calories). The researchers tested the effect of consuming the additional protein at specific meals - breakfast, lunch or dinner - or spaced evenly throughout the day.

Purdue researchers found that the feeling of fullness was greatest and most sustained throughout the day when the additional protein, from eggs and lean Canadian bacon, was eaten at breakfast - versus lunch or dinner.

Additional Research
This study adds to a growing body of research on the benefits of eating high-quality protein for weight management. Recent research provides further evidence to support the findings of this study:

Making the Most of Breakfast
The authors of the British Journal of Nutrition study note that most Americans typically consume a relatively small amount of protein at breakfast - only about 15 percent of their total daily protein intake.

Additionally, consumer research by the International Food Information Council shows that 92 percent of Americans cite breakfast as the most important meal of the day, however less than half (46 percent) eat breakfast seven days per week.iv

"It strikes me that there is a real opportunity to increase protein intake at breakfast to see a meaningful impact on people's weight loss efforts," said Keith Ayoob, EdD, RD, FADA, a nutritionist and associate professor of pediatrics at the Albert Einstein College of Medicine. "Many people are caught in a boring breakfast rut, or say they simply don't have enough time to eat in the morning, but with a little planning, breakfast can easily be one of the most fulfilling meals of the day."

Ayoob provides the following tips for easy, high-quality protein based breakfasts:
