The study, which is published in the British Journal of Nutrition, found that high-quality protein foods, such as eggs or lean bacon, can provide a sense of fullness, reducing the amount of additional food that people feel they need throughout the rest of the day.
Dr Wayne Campbell, study author and professor of foods and nutrition at Purdue University, commented: "There is a growing body of research which supports eating high-quality protein foods when dieting to maintain a sense of fullness.
"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."
Suggestions for a healthy high-protein breakfast include using the previous night's leftover vegetables to fill an omelette, or combining yoghurt with fruits and whole grains.
Alternatively, consumers could take a warm whole wheat tortilla and fill it with lean bacon, scrambled eggs and low-fat cheese.
