To the delight of registered dietitians everywhere, both fiber and protein have gone viral. By now, you’ve no doubt heard all about the benefits of each one. For fiber, this includes gut health, weight loss, and the decreased prevalence of type 2 diabetes. For protein, this includes building muscle, immune system support, and regulating appetite. But is there an optimal time to eat fiber? Protein? A combination of the two? A newly published study might hold the answer.

The Study

The study, which was published in the British Journal of Nutrition, sought to determine if what you eat and when you eat it could lead to weight loss. It examined a small, randomized control group of 19 adults, who were clinically diagnosed as being overweight or obese. The study followed these individuals as they ate a high-fiber or high-protein diet for 28 days, after which they then swapped diet plans.

For each of these diets, the most calories — 45% of them to be exact — were consumed at breakfast; additionally, 35% of the calories were consumed at lunch, and 20% at dinner. Subjects on the high-fiber diet plan ate at least 30 grams of fiber per day. Those on a high-protein diet ate a combination of poultry, fish, red meat, eggs, and dairy; their fiber intake was also limited to no more than 15 grams per day. (Both eating plans were based on a 2,000-calorie diet.)

The Results

Researchers found that those on a high-fiber diet lost an average of 10.7 pounds, while those on a high-protein diet lost an average of 8.5 pounds. In addition, those on a high-fiber diet experienced greater gut health benefits. Researchers also concluded that the high-protein diet was superior in suppressing a person’s appetite.

Bottomline: As this study shows, fiber and protein each have specific health benefits; as such, you should be consuming both at breakfast time. Not sure where to begin? Check out the recipe suggestions below.
