Homemade Protein Bars

Protein is arguably the most important nutrient for people who work out. When you exercise, your muscles are broken down in a process called catabolism. After your workout, when you rest and sleep, your body repairs this damage, a process called anabolism.

The muscle repair process requires protein, which contains substances called amino acids. Your body uses amino acids like building blocks, shoring up and reinforcing the damaged muscle cells so that they become bigger and stronger.

While opinions vary, most nutrition experts believe that exercisers should eat about 1.8 to 2.0 grams per kilo of body weight. That’s about 0.8 to 1.0 grams per pound. The heavier you are, and the harder you work out, the more protein you need. Consuming too little protein could severely undermine your training progress.

Eating enough protein is not always easy. High-protein foods, such as meat, fish, eggs, and dairy, usually require cooking and are not always portable or convenient to eat. You can use protein powder to increase your protein intake, but a lot of people prefer to eat their protein rather than drink it.

Protein bars are an excellent alternative because they’re both portable and convenient and taste good too.

While there is nothing particularly wrong with buying your protein bars, you’ll have more control over your diet if you make your own homemade protein bars.

Homemade protein bars are usually more natural than the store-bought version, and you can easily modify your chosen recipe to suit your tastes and nutritional needs.

Can I Make My Own Protein Bars?

Making your own protein bars can be very straightforward. In fact, if you hunt around the internet, you’ll find lots of recipes to try, many of which don’t even need baking. But there is a drawback – they won’t taste much like the protein bars you can buy in stores and gyms.

Many commercially-made protein bars taste a lot like candy bars, and there are even high-protein versions of things like Snickers and Mars bars to buy. Made using machines and processes and ingredients that aren’t typically available to home bakers, your homemade protein bars can’t compare to something bought from a store.

That said, your homemade protein bars will be fresher and contain all-natural ingredients, so, potentially, they could be healthier too. However, you probably won’t confuse it with a candy bar!

Bottom Line

Store-bought protein bars are often all but free from sugar and carbs. That’s because they’re sweetened with things like sugar alcohols and held together with artificial setting agents and emulsifiers.

Homemade protein bars are invariably more natural, and that may mean they’re healthier. They’re usually cheaper and often taste better, too.

Finding your perfect homemade protein bar recipe may take a few attempts, and you’ll probably need to modify and finetune your ingredients to make the best possible version. However, once you master making your own protein bars, you’ll be rewarded with a bar that matches not just your nutritional needs but your taste buds too.
