Can I Eat A Protein Bar For Breakfast?

In general, you can eat a protein bar for breakfast. It is a good solution for busy people who don’t have time in the morning. High-quality protein bars can add over 20 grams of protein, and plenty of fiber to your existing breakfast, as well as they, can be eaten on their own.

So there are many ways to skin the cat. And if you already have a breakfast like breakfast cereals, then in my opinion a protein bar is a much better choice. Here’s why

Are Protein Bars Good For Breakfast?

As a whole, protein bars are good for breakfast because they provide a good source of protein, fiber, and several vitamins and minerals. Protein bars are often enhanced with caffeine and herbs such as ginseng which can lower glucose and improve energy.

Having a protein bar is a great start especially if you’re in a calorie deficit.

  • It’s small
  • It’s delicious
  • It lowers hunger
  • It gives protein

I know you may think that protein bar is ultra-processed food.

I get it.

But when you look around, almost everything we eat is highly processed, too.

  • Breakfast cereals
  • Cheese
  • Fruit yogurt
  • Energy drink
  • Chocolate bar
  • Baby formula

In fact, over majority of products in the Walmart or Costco is somehow processed (source).

So if you’re ok with eating breakfast cereals, or mars bar, then tell me.

What is different with protein bars?


I’m not saying you should only eat protein bars. In fact, you can get really creative. Because just like the breakfast cereals, you can combine your protein bar with other foods to make a more compound meal.

What Should You Eat With A Protein Bar

In general, there are several foods you can eat with a protein bar. It can serve as a snack replacement with your morning coffee. Also, it can be eaten with yogurt, oatmeal, fruits like apples or bananas, or even with another protein shake.


Ideally, I would love to have for breakfast:

  • Freshly baked French-flour croissant
  • Still warm blueberry pastries
  • Water from just chopped coconut
  • Italian espresso

But it’s not gonna happen.

Because I’m too busy. We are all busy. We’re all juggling.

  • One or more jobs
  • School
  • Family responsibilities
  • Early-mornings and late-nights
  • And million other things

So it will all depend on how much time you have.

Because for jugglers like you and me who struggle with time in the morning, having a protein bar on its own is good enough.

But if you have a little extra time, and you want to add something more to your protein bar, here are my best choices.

This will take 20 seconds longer than your typical breakfast:

  • Take a knife and a chopping board
  • Take one to two breakfast bars (ideally from the fridge so they taste better)
  • Chop the bars into small stripes and crumbles
  • Take a bowl
  • Put the yogurt into the bowl
  • Put all the stripes and crumbles of the protein bar into the bowl and mix

You welcome.
