What's the Best Ketogenic Protein Powder?
Low-Carb Keto-Friendly Whey

best keto protein powders review - cover

Finding the perfect whey supplement on a low-carb high-fat diet, especially the keto diet, is a challenge. There are so many keto protein powders on the market, it’s tough to narrow down your choices no matter what your other dietary needs are, but when you need a low-carb shake it can be especially difficult to make the right choice. That's why we decided to get involved and review the best keto protein powders that we have found on the market today.

And the truth of the matter, is that most supposedly "keto-friendly" protein powders actually aren't keto-friendly but we'll get into that in just a little bit.

​First and foremost, make sure you are getting as much nutrients as possible from natural sources by eating eggs, fish, meat, nuts, and other foods that are high in protein and low in carbohydrates to ensure weight loss. It’s unlikely you’ll reach your intake goals for each day with just food, so you might have to turn to supplements to get there.

​Next, rule out a number of ketogenic diet shakes from your list of potential choices based on their general profiles. For instance, sweetened products are an option that improves the taste of the product, but it usually boosts the sugar content in the powders. Many flavored or sweetened protein shakes contain about 8 to 10 grams more carbohydrates than unsweetened powders. If you want something with flavor, look for ones that utilize lower calories sweeteners—preferably ones that are natural—for taste.

Also, make sure you consider absorption. All the ketogenic protein shake in the world isn’t going to do your body any good if your body is unable to assimilate it. Proteins are assigned a digestibility rating that’s called the protein digestibility corrected amino acid score that’s based on how well your body is able to digest the amino acid in the product. Whey, casein, and egg whites have higher scores than peas and hemp for example. The higher the score, the better your body is able to use the nutrient.

​So, what are three of the best low-carbohydrate protein powders on the market that is keto-friendly?

How Much Protein on Keto Diet Do You Need?

different kinds of protein

So, let's get this question all figured out. How much protein exactly is allowed when you're on the ketogenic diet?

If you are like most people , you will need to keep it at around 15% or maybe even less to just stay in ketosis. This amount prevents your body from starting gluconeogenesis so that you can maintain the state. Although, some people might be able to squeak by with a higher level of intake but this is not very common.

If we are talking about how much protein in grams you need in order to stay within the rules of the ketogenic diet then we're looking at around 0.7 to 0.9 grams per pound.
