Only got a specific number of calories left in the day and still need to hit that protein mark? We have recently added the nutritional info of protein per 100 calories to the protein bars within our food discovery tool and database of over a thousand food items.

With this new nutritional metric we have answered the question of which protein bars have the most protein for the least amount of calories right here in the suggestion table below.

If you want to see a definitive and growing list of protein bars and their protein per 100 calories nutritional info, just scroll down the article.

Why Would Protein Per 100 Calories Be Useful To Know

This information is useful for anyone who wants to get the most amount of protein they can whilst consuming as little calories as they can.

If you have a daily or weekly limit of calories and you need to limit your calories but still get as much protein as you can, the top protein bars here will definitely help you get the protein you need with the lowest amount of calorie intake.

This is because the suggestion table below of nearly 200 protein bars are listed to show those which have the most protein for 100 calories, so every single protein bar in this list is compared fairly as though it is a 100 calorie protein bar.

The result is the amount of protein you get from each.

You have to remember that each bar when purchased and consumed does not come in at 100 calories, the least has 74 calories, which is the Primal Strips, so this makes them a really great option because you get the smallest amount of calories of any protein bar here and you still get a big protein amount, 10 grams of protein.

At the other end of the spectrum, Fit Crunch offer protin bars with 30 grams of protein in them, but you will have to consume 380 calories to get that protein from it, that is a big calorific sacrifice for the amount of protein offered.
