The ketogenic (or keto) diet is a very low carbohydrate, high-fat diet, which forces your body to burn fat for fuel instead of glucose (sugar) from carbs. If you’re following a ketogenic diet, you may have difficulty finding a keto-friendly protein powder. This is because many protein powders contain a significant amount of carbohydrates. 

On a ketogenic diet, only about 5 percent of your daily intake should come from carbohydrates in order to keep your body in ketosis, or the sensitive fat-burning cycle. For this reason, it’s important to select a protein powder with plenty of fat and protein and minimal carbohydrates.

What to Look for in Keto Protein Powders

Protein Forms:

Protein powders come in many forms, including concentrates, isolates, and hydrolysates. Protein concentrates are made from extracting protein from whole foods and contain 60 to 90 percent protein and 20 to 40 percent fat and carbohydrates. Protein isolates are filtered more and supply 90 to 95 percent protein with very little fat and carbohydrates. Protein hydrolysates are formed by heating the protein with acid or enzymes, which breaks the bonds between amino acids, making the protein assimilate more quickly into your body and muscles. 

When following a ketogenic diet, look out for the form your protein powder comes in because it’s important to choose a protein powder that is very low in carbohydrates. If you select a protein concentrate, the product may be high in carbohydrates relative to sources from protein isolates or hydrolysates.

Added Sugar:

Many protein powders on the market now are sweetened zero-calorie sweeteners like stevia, monk fruit extract. When possible, avoid products with other artificial sweeteners and sugar alcohols.

Some protein powder products may contain added sugar, which is something to steer clear of on a ketogenic diet. Sugar is a carbohydrate, so it will significantly increase the amount of carbs in your protein powder. It’s best to limit added sugar in the diet regardless of whether you follow a keto diet, so this tip applies to everyone.

Additional Ingredients:

Some protein powders contain additional ingredients that have added health benefits. If you are interested in getting more out of your protein powder, try one with ingredients like BCAAs, MCT oil, probiotics, or prebiotics.

Can I use a keto protein powder to make a meal replacement shake? 

You can absolutely use keto protein powder to make a meal replacement shake. Remember that meal replacement shakes should still have a good balance of ingredients that keep you full, give you energy, and satisfy you for at least a few hours. For a keto diet in which you’re limiting carbohydrates, a shake should include a good balance of protein, healthy fats, and fiber. Ensure the shake has enough calories to give you energy—about 300 to 350 calories or more to replace a full meal.

To make a keto protein shake, you can add healthy fats like coconut, avocado, or plain almond butter in addition to your protein powder. You should also include a fiber source, which helps keep you full and provides digestive and gut health benefits. Good sources of fiber that are low in carbs include non-starchy vegetables, almonds, chia seeds, flax seeds, and berries.

How do I bake with keto protein powder?

You can make many baking recipes keto-friendly by substituting flour with protein powder. This reduces the amount of carbohydrates and increases the recipe's protein content without greatly compromising on taste.

Baking with keto protein powder usually takes a little trial and error. One tip is to start by replacing one-third of the flour in a recipe with an equal amount of protein powder. If that works well, you can increase the amount of flour you replace with the protein powder next time you try it.

For most recipes, use an unflavored protein powder to maintain the original flavor of the baked good. You can also experiment with different flavors, like using chocolate protein powder for baking protein brownies.
