In my opinion, breakfast is one of the easiest meals to increase overall fiber intake – a nutrient that we often don’t prioritize despite decades worth of research showing numerous benefits. That’s why I’ve created this 21-day high protein and fiber breakfast challenge! Prioritizing these two help keep you full and energized – and can be a game-changer for overall health.

The dietary guidelines were created to help Americans reduce their risk of chronic disease. Unfortunately, over 90% of Americans are not meeting the recommended daily fiber intake. This is a topic I am very passionate about. Therefore, I’ve put together this fun challenge with recipes that prioritize both protein and fiber with weekly grocery lists included!
The best part about this challenge is that most recipes are SO easy to meal prep and you’ll have a grab-and-go option on busy mornings. These breakfast options vary from just 5 minutes of prep to an hour of cooking time.
Why You Should Try This Breakfast Challenge
- It’s fun and will set you up for a successful day. This challenge is supposed to be fun and motivating while also making your busy mornings a little easier because breakfast is already prepped!
- Reduced risk of chronic diseases. Multiple studies have demonstrated that a high fiber intake reduces the risks of obesity, type 2 diabetes, cardiovascular disease, colon cancer and pre-menopausal breast cancer.
- A healthier gut microbiome. Fiber is one of the key components to better “gut health” which affects our digestive system, immune system, and even our mental health.
- Weight management. Both protein and fiber help to slow down the digestion of our food, keep us fuller for longer with some studies showing reduced appetite and lower overall caloric intake. Protein, specifically, is associated with positive changes in body composition.
- Increased antioxidant consumption. By prioritizing well-balanced breakfasts you will also be increase overall fruit and veggie consumption which has also been shown to reduce disease risk!
- Longevity. A meta-analysis of multiple studies found that a higher fiber intake was associated with a lower risk of death.
- Improved regularity.
How to Do the Challenge + Recipes
A quick note on servings: Some of the recipes in this challenge make 4 servings, even when only 2 servings are included in the 21-day schedule. I’ve included the full recipe ingredients in the grocery lists so you don’t have to scale everything down.
Save the extra servings for another breakfast, freeze them for later, or use them to swap in for another day in the challenge.
