Protein Bar restaurants are committed to a better way of living and offer flavorful and nutrient rich food and drink. Matt Matros founded Protein Bar in 2009 with the goal of bringing nutrient-rich, great-tasting food to on-the-go customers. Growing up overweight and losing his father to a heart attack at a young age, Matt saw the connection that diet and stress have on one's health. At age 22, Matt realized that he was on the same unhealthy path as his father and decided to make a change. With a commitment to doing the work to improve his life, Matt transformed through exercise and a protein-rich diet into a fit, healthy adult - losing 50 pounds along the way. Struggling to find convenient places to eat in a manner that supported his new lifestyle, Matt left his career in brand management and spent his entire life savings to open the first Protein Bar at Franklin and Adams in downtown Chicago.

Proteinmaxxing 🤝 Fibermaxxing

Why choose when you can do both?

Fiber supports digestion, keeps you feeling satisfied, and deserves a little more attention in your daily line-up.

We’re breaking down the “fibermaxxing” trend - and sharing PBK orders that bring plenty of fiber to the table, alongside 15g+ of protein in every order.

Marathon training isn’t just about putting in the miles. It’s about what you do after them, too. 🏃‍♀️

Carbs to replenish your energy, protein to support muscle recovery, and fluids to rehydrate. Your post-run meal has a job to do!

Swipe for a little recovery 101 and a few PBK orders to add to your post-run rotation. 💪
