Energy Bars Buying Guide & Tips

With all the options on the market these days, trying to figure out which energy bars to take with you on your ride can be a confusing process.

We want a bar that will give us the best performance results and that tastes good too.

So let’s take a look at the things to know before buying energy bars.

Types of Energy Bars

If you walk around the supermarket, you’ll quickly notice that there are several types of energy bars.

The table below shows a general overview of the differences between each type of energy bar.

Carbohydrate Bars

The goal of carbohydrate bars is to give you as much energy as possible as quickly as possible and in as small a package as possible.

Most carbohydrate bars such as the Powerbar and SIS will give you around 20g of carbs per ounce mostly in the form of sugars such as fructose and glucose. 

Carbohydrate bars generally have between 200 and 300 calories per serving.

These bars offer lower levels of protein (usually less than 10g). This is for a good reason.

Your body can turn carbs into energy much more quickly than protein. Ingesting too much protein with your carbs will slow this process down leading to an energy drain. Unless you’re going on a longer ride you won’t need protein until after your ride is over.

Protein Bars

As cyclists, we mostly think of protein as something that’s important after the ride is over.

And for the most part that’s true.

Protein helps to rebuild muscle tissue, preparing you for the next ride.

But if you’re in the saddle for more than three hours, you’ll need protein before getting off the bike.

When you’re on the bike, protein slows digestion by lowering the glycemic index of foods. This forces your body to use more fat for energy, helping your body to avoid blood sugar spikes that result in the dreaded bonk.

Meal Replacement Bars

These bars take nutrition to another level and therefore need to be held to higher standards.

After all, they’re replacing an actual meal. To qualify as a meal replacement bar, a bar needs to offer at least 300 calories and include real food ingredients such as fruits, nuts, vegetables, and whole-grain oats.

These bars should include healthy doses of carbs, fiber, and protein.

Energy Bar Ingredients

Energy bars use a variety of different ingredients, some good and some bad, to deliver the large amounts of carbohydrates and proteins they advertise on their labels.

Healthy ingredients include nuts and seeds, which are good sources of fiber and protein, whole grains, which provide carbohydrates and fiber, and natural sweeteners in the form of dried fruits such as dates and raisins.

The not-so-good ingredients include plain old sugar (the white and corn syrup kind), partially-hydrogenated oils, which are the dreaded trans fats that cause all sorts of health problems, and a whole array of artificial ingredients that are used for coloring, flavoring, preservatives, and sweeteners.


If you’ve never heard the old cycling adage if you’re hungry, it’s too late, then it’s time you learned it now.

For peak performance, you need to eat on a schedule. If you wait for your body to communicate to your brain that it’s time to eat, then it means you’re already out of fuel. At that point, it’s too late to replace those carbs before you experience an energy crash.

This means you need to eat before you feel hungry. It’s a heck of a lot easier to do that with a bar that tastes good than with one that you have to choke down.

Fortunately, energy bar makers know this, so they give you a whole host of flavor options, including everything from chocolate to pumpkin pie to oatmeal raisin, and even vegan varieties.

For example, the SIS bars come in 5 different flavors, while the Clif Bar has 12 different flavors to choose from!

Energy Bars vs Real Food

In a perfect world, there would be an energy bar that provides you with the right nutrients for peak performance and tastes exactly like pizza. 

Despite all the efforts bar makers put into making a palatable bar, an energy bar will never be quite like real food.

That said, these same bar makers have spent millions of dollars to create easily digestible bars that will provide maximum energy transfer into your system. For example, RXBAR uses egg whites, dates and nuts as their ingredients to their bars, avoiding preservatives and fillers.

Real food also presents a convenience issue.

Whereas energy bars are designed to be eaten while riding, there are few real food options out there that allow you to comfortably and safely ride and eat. With this in mind, bars, along with energy gels and energy drinks, are your only option when it comes to races or those competitive Sunday morning club rides.

That’s not to say there is no place for real food. 

The strong taste of energy bars can become nauseating during a long ride. For those rides with planned stops, bananas, apples, peanut butter packs, and even a turkey sandwich will provide you with plenty of energy and a meal you’ll enjoy.

And, of course, one of the best parts of cycling is the guiltless eating of carb and protein-rich real foods once the day is done. Feel free to gorge on real food after a long day in the saddle. The protein and calories in real food are an essential part of your body’s recovery.

Is it too much to ask for an energy bar that is gluten-free and vegan?

The folks at Skratch Labs, a company started by a pro cycling coach that wanted a natural bar for his cyclists, don’t think so. This company has developed a bar that is devoid of grains, meat, and dairy.

The Anytime Energy Bar uses nuts, seeds, quinoa, and oats to deliver 27g of carbohydrates and 5g of protein in a 50g bar. This is impressive considering the bar only includes 4g of sugar.

The Anytime energy bar has 210 calories.
