Many people are getting into ketosis. But, the big question is that is it okay to take a keto whey protein on a keto diet? What would be the effect of this protein drink in achieving ketosis?

To be able to find the answer for these questions, let us first identify the basics…

What is Ketogenic Diet?

A ketogenic diet is a diet that contains low carbohydrates, moderate amount of protein, and high in fat. The primary target of this diet is to take your body to get the optimal level of ketosis. Ketosis is the state wherein the body has a low level of blood sugar or glucose. Due to this, the liver produces ketones through burning of the stored fat in the body. From then, instead of using the stored glucose from carbohydrates, it is the time that the body uses ketones as energy.

The Basics about Whey Protein

Basically, cow’s milk is the source of whey, sometimes it could be from sheep or goat. Milk has two primary proteins. Generally, it contains around 80% of casein and 20% of whey. The separation of the dairy will give the solid and the liquid portion which is the casein (solid part) and the whey (liquid part).

From here, these products will be produced based on the extraction and filtration process:

1. Whey Protein Powder
– This is the least concentrated form and contains significant amount of lactose, usually this is used commonly in food products.

2. Whey Protein Concentrate
– The moderately concentrated form among the three, whey protein concentrate has less lactose and is generally used as a supplement.

3. Whey Protein Isolate
– Whey isolate is the most pure and highly concentrated form of whey that contains minimal amount of lactose. Moreover, it is also good for protein supplementation. Among the three, this type of whey is the highest quality choice and the most applicable for lactose intolerant individual.

The Components of Whey Protein

Whey protein contains the 9 essential amino acids. Amino acids are building blocks of proteins and aid in the formation of the body tissues of the muscles, skin, hair, and nails. Basically, they cannot be synthesized by the body; they usually come from food, that’s why they are essential.

Whey protein also contains the BCAA or the branched-chain amino acid which primarily promotes muscle-building. Moreover, the BCAA made up the 35% of the protein located in the muscle tissue. In addition, it is known primarily for its growth enhancing factor.

One of the main types of BCAA is the leucine which plays an important role in the muscle protein synthesis. Furthermore, whey protein contains high amount of leucine. Additionally, whey protein also contains cysteine – the amino acid precursor that aids in the production of glutathione.

Moreover, below are some of the bioactive compounds that are included in whey protein:

  • Lactoferrin
  • Alpha-lactalbumin
  • Beta-lactoglobulin
  • Immunoglobulins
  • Lactoperoxidase
  • Lysozyme

Whey Protein while on Keto Diet

Generally, to be able to get into ketosis, carbohydrate should be restricted. But, how about drinking a keto whey protein? Can you still get into ketosis while drinking your protein shakes?

Well, there are other factors that you might still need to consider first to get you out of ketosis. Basically, about 5 – 10% calories from carbohydrates are needed to get or stay into ketosis. So, more than that, you will be kicked out.

On the other hand, will a keto whey protein can get you out of ketosis? Well, the answer primary depends on the protein powder.

A mass gainer that contains 100 grams of carbohydrates will probably get you out of ketosis. However, you don’t need to worry if you are using a protein powder that only contains 0 – 3 grams of carbohydrates. You are still on track. What you’ll need is to monitor your daily consumption of carb and ensure that you won’t go beyond the limit.

How about too much consumption of protein while on ketogenic diet? Does additional keto whey protein help to get you out of ketosis?

Generally, many dieters assume that aside from too much carbohydrate, high intakes of protein can also a factor to get you out of ketosis. However, there is still no substantial evidence to prove this assumption.

Scientifically, too much protein intake will allow your body to convert protein into glucose. This may lead your body to have enough amount of glucose instead of fat which will then get you out of ketosis. Primarily, this process is known as glucogenesis. But, there is no studies that reveal glucogenesis will kick you out of ketosis.

A low carbohydrate diet will lead to the hormonal changes that include a decrease in the amount of insulin that circulates together with the high amounts of glucagon. These changes are in favor of glucogenesis. But, the body restricts the use of glucose to diminish the demand for glucogenesis.

Keto Whey Protein for Weight Loss

One of the good things about the ketogenic diet is that it aids people to shed fats. Switching the energy source from glucose to ketones, the body does not only burn the fat from the food you eat, it also begins to burn the fat stored in the body as well.

While on a ketogenic diet, food consumption becomes lesser. However, you will able to stay fuller for a longer span of time because of the following:

1. Low levels of ghrelin – known as the hunger hormone
2. High amounts of cholecystokinin or CCK – hormone that is responsible in reducing the appetite by binding to the brain
3. Reduced neuropeptide Y – an appetite stimulant primarily based on the brain

Keto Whey Protein to Increase the Fat Burning Process

Since the ketogenic diet only needs a moderate amount of protein, it doesn’t mean that you should totally avoid all the sources of protein. Keep in mind that protein is still an essential component of the diet and even weight loss program including keto diet.

Basically, the moderate amount of protein needed in the diet is used to keep the muscular composition of the body in a lean state. To aid in this issue, the solution is to incorporate some amount of keto whey protein in your diet along with MCT oil and nut butter.

Using Whey Protein while on Keto Diets

Even though it is clear that keto whey protein doesn’t get you out of ketosis, for some, there is still small probability that it could. In fact, all individuals are unique and the effect wouldn’t be the same. That’s why some people are claiming that keto whey protein is one of the factors that get them out of ketosis.

One thing to make ensure that you are still getting into ketosis while having your keto whey protein, it is better to monitor the ketone levels in your body. To be able to do that, below are the methods that could be of great help.

1. Using Ketostix

By using ketostix you may be able to monitor your ketones in the easiest and cheapest way. However, this method is not the most accurate way to check it.

To make it work, basically, you have put your urine sample on one of the strips. It will eventually change in color. Match the strip color against the colors indicated in the bottle for you to identify the ketone levels that your body is producing.

But, urine testing can give a misleading result most of the time. The reason for this is because the ketones need more time to be seen in the urine. Meaning, the result of the ketostix is based on the old results and not actually the present ketone state.

Additionally, ketostix is only able to measure acetoacetate, one of the three ketone bodies that is not a good indicator of ketosis. To be able to determine the ketone levels in the body, you have to measure the beta-hydroxybutyrate. This ketone body would be measured by a ketone blood meter.

2. Using Ketone Blood Meter

Compared to ketostix, ketone blood meter is more expensive. However, with this method you can able to accurately measure the body’s ketone levels.

Simply place a strip into the test meter. Draw a small drop of blood from your fingertip using a lancet pen. At the end of the strip, you have to place a small amount of blood. The meter will then read and show the results.

An optimal ketosis level has a reading of about 1.5 – 3 mmol/L. Generally, measuring your ketone level using a ketone blood meter is the best option if you want to determine if the consumption of the keto whey protein really affects your ketone level.
