If you're simply looking to maximise your protein intake from a snack bar, then you probably won't find many with a higher protein content than these MET-Rx Bars.


The cookie flavour, for example, contains 32g of protein within a 100g bar, a highly impressive number considering they're simply a bar.

Given their larger size, they also come with slightly more calories at 410 than your regular bar, but that means they could be the ideal option if you're looking to bulk up.

Frequently Asked Questions About Protein Bars

People tend to have a lot of questions regarding protein bars, especially as there are a lot of common misconceptions, but we're here to clear up some of the more typical queries you may have.

Is It Bad To Eat Protein Bars Every Day?

Like with all supplements, protein bars are a great way of increasing your daily protein intake, but should never be a replacement for whole foods and meals.

You'd simply miss out on many of the key micronutrients that come with eating whole foods such as chicken, beef, and fish, so wouldn't be beneficial and supportive of a well-balanced diet.

With that being said, if you're looking for something quick, tasty, and easy to eat, perhaps after a tough workout, to just tip you over your daily intake goal, then protein bars are an effective way of doing that.

Generally speaking, eating one bar a day is perfectly fine, but any more than that is pushing it, especially as you have to be careful of the sugar content of some of the bars on the market.

Are Protein Bars Worth It?

Some protein bars out there can be quite expensive and, when you dig a little deeper, you may find they don't actually contain as much protein as you first thought.

So, in answer to the question, yes they are worth it if you find the right protein bars for you and your diet, and use them only for supplemental purposes.


For example, if you're looking for a decently sized protein-dense snack to help you up your daily intake, then the aforementioned Grenade Carb Killa bars can offer you 23g of protein per 214 calories, making them a useful supplement to add to your diet.

Do Protein Bars Make You Gain Muscle?

In short, no. Just consuming protein bars will not instantaneously make you more muscular and, in fact, will probably have an adverse effect on your weight.

You need to team eating protein bars, and a high-protein diet in general, with adequate amounts of exercise.

For building muscle, this will typically be weightlifting, and protein can help by repairing broken down muscles worked out in the gym.

Be warned though, protein is just one piece of the puzzle, with a number of other factors like sleep and stress also influencing your training.
