Best Keto Protein Shakes
for 2024

If you’ve spent any time researching how to best build muscle, lose excess fat, or both, you’ll know that using protein powders and shakes are great ways to hit your goals.

Today, the science is clear that diets with excess carbs and sugar lead to weight gain while a diet high in protein and healthy fat fuels a lean and fit physique. Both protein powders and the keto diet have been around for a long time, but in recent years have re-emerged in the health and fitness world. The ketogenic diet transitions the body into a similar state as intermittent fasting. The keto diet was first introduced in the 1920s to help treat epilepsy. The treatment was standard for nearly two decades until the modern era of antiepileptic drug treatment took over.1

Protein powder goes back much further, to nearly 8000 years ago when the art of cheesemaking was first developed. When milk was treated with acid, people noticed that a coagulated milk gel was left, and the solids could be turned into cheese. The liquid-like by-product left over from the process was discarded, used as a starter culture for the next day’s cheese, or used as a pig feed. This by-product is known as whey. Although it took thousands more years to refine raw whey into powder form, today it’s one of the most widely marketed types of protein powders sold.

Now that you have a little background and perspective on protein powder and keto, you’ll better appreciate what you’re about to discover here as you read. We’re assuming you know that a ketogenic diet is one of the most effective diets for shedding fat. You also know that a low-carb or no-carb keto-friendly protein shake will be essential as you progress through your journey.

However, there’s an endless amount of keto protein shakes to choose from. How do you know which one will give you the best results? Keep reading and find out.

We’re going to look at the best keto protein shakes available in 2024 and break down what makes them different, why certain types of protein are better, and give you all the information you need to make an informed decision.

Types of Protein Powders

The first step in choosing the best keto protein powder is understanding the types of protein powders available and what makes them different.

Protein powders are concentrated protein sources from animal or plant food, such as dairy, eggs, rice, or peas.

There are three common forms:

1. Protein Concentrates

Protein concentrates are produced by extracting protein from whole food using heat and acid or enzymes. They typically yield 60-80% protein and 20-40% fat and carbs. Whey protein powder is the most common form.

2. Protein Isolates

Protein isolates require an additional filtering process to remove additional fat and carbs, yielding a more highly concentrated protein powder. Protein isolate powders contain around 90-95% protein.

3. Protein Hydrolysates

Protein hydrolysate powders go one step further by adding additional heat, acid, or enzymes to break the bonds between amino acids. The result is a protein powder that’s more quickly absorbed by your body and muscles. The problem with hydrolysates, especially in the case of whey protein, is that they raise the body’s insulin level faster than other forms. This is not ideal if your goal is to burn fat.

Most Common Protein Powders

Now that you understand the different forms of protein powder, let’s take a quick look at the seven most common protein powders you’re going to encounter. We’ll tell you what they are, where they come from, and why they fall short compared to the best keto protein shake.

Whey Protein Shakes

As you know, whey protein comes from milk. It is the liquid that separates from the curds during the cheesemaking process. It’s high in protein and one of the most affordable protein powders on the market.

Whey protein shake cons:  

Whey protein contains lactose, a milk sugar that many people have difficulty digesting. This sugar can also cause massive spikes in insulin and rapid weight gain.

Casein Protein Shakes 

Like whey, casein is a protein found in milk. However, casein is digested and absorbed much more slowly. Casein forms a gel when it interacts with your stomach acid, slowing down stomach emptying and delaying your bloodstream’s absorption of amino acids.

Casein protein shake cons:

Clinical evidence points out that casein may cause adverse reactions in some people, especially those with lactose intolerance.

Egg Protein Shakes

Egg white protein powder contains about 25 grams of protein in a 30-gram serving size. It has about as much protein as whey and casein-based protein powders. Egg white protein powder, however, lacks the lactose contained in casein and whey.

Egg protein shake cons:

Egg white protein shakes are not very filling compared to other options, so if weight loss is your goal it might not be the best option. Also, some people with dairy allergies find it intolerable.

An Amino Acid Supplement Engineered to Build Muscle

Pea Protein Shakes

Pea protein powder is especially popular among vegetarians, vegans, and people with allergies or sensitivities to dairy. It’s made from the yellow split pea, a high-fiber legume containing all but one essential amino acid. Pea protein is also particularly rich in BCAAs.

Pea protein shake cons:

Pea protein is low in methionine+cysteine, which makes it an incomplete protein. These shakes are also high in carbohydrates, which is not ideal if your goal is losing weight.

Hemp Protein Shakes

Hemp protein powder is another plant-based supplement that is gaining popularity. Hemp is rich in omega-3 fatty acids and several essential amino acids.

Hemp protein shake cons:

Hemp is not considered a complete protein because it has very low levels of the amino acids lysine and leucine. Better options exist if your goal is to maximize muscle growth and shed excess fat.

Brown Rice Protein Shakes

Protein powders made from brown rice have been around for a while now, but they are generally considered inferior to whey protein for building muscle.

Brown rice protein shake cons:

Although rice protein contains all of the essential amino acids, it is too low in lysine to be a complete protein. Rice protein shakes are also high in sugars, which is not suitable for losing weight.

Health Benefits of Drinking Keto Protein Shakes

Health Benefits of Drinking Keto Protein Shakes

There are a lot of benefits packed into a keto protein shake. For most people, the primary benefit is the variety of protein smoothie recipes. Some people use almond milk, and others use coconut milk. One person adds chia seeds and the other peanut butter or almond butter.

The more carbs you add, the less keto-friendly your shake is, but small amounts can keep you within the threshold. Unsweetened cocoa powder and unsweetened almond milk are favorites in keto recipes because of their low calorie count per serving.

So what are the benefits people enjoy when bringing keto protein shakes into their lives?

Keto Protein Shakes are Convenient

Whole food should be the base of any healthy diet, but whole food protein sources aren’t always easily available, especially if you’re traveling, between the gym, the office, and even at home.

Keto smoothies make a low-carb diet tolerable. You can choose a recipe, put everything in a blender, and blend. If you want something with minimal prep time, just mix your powder with water and drink it.

Keto Protein Shakes Help you Build Muscle Faster

Along with keeping you on track with your low-carb diet, keto protein shakes are instrumental if muscle growth is your goal.2 High-quality, fast-absorbing keto protein shakes that you drink right after your workout provide tremendous support for recovery and faster muscle growth.

Keto Protein Shakes Help You Lose Weight

The biggest challenge for most people trying to lose weight is fighting off hunger pains. To lose weight, you must restrict calories, but that doesn’t mean you have to be hungry. A lot of overweight people have been eating “empty calories.” These are high-calorie foods that do little to satiate hunger. These foods taste great and are highly addictive due to engineered flavors and added sugar. Once you substitute high-calorie “empty calorie” foods with high protein low-calorie protein shakes you’ll notice you have more energy, feel less hungry, and can better maintain your weight loss.

Fortagen with scoop

Why is Fortagen the Best Keto-Friendly Protein Powder?

Fortagen was created to fill the gaps in the keto protein market. Consumers wanted a vegan protein with zero carbs, low calories, and high protein. People were looking for a protein shake they could use to not only build muscle, but one the body would fully utilize to better help with recovery.

The Perfect Amino Acid Profile

Fortagen outperforms whey protein and other essential amino acid supplements because it’s designed to provide the amino acid profile your body needs, in the perfect ratio. Whey protein is loaded with nonessential amino acids your body already has a surplus of.

Superior Bioavailability

When it comes to the impact of different proteins, bioavailability is one of the most important metrics to consider. Fortagen is digested in under 30 minutes, while whey or vegetable-based proteins can take up to 6 hours.

Gentle on Your Digestive System

Intestinal irritation to protein powders is one of the most common complaints. Lactose intolerance leads to bloating, gas, and stomach cramps. Milk proteins can cause inflammation even for those who are not lactose intolerant. Excess mucus production is a classic sign of inflammation.

Minimal Calories

Standard protein powders come packed with calories. It’s not uncommon to see a powder with 120 calories per scoop. If you’re on a calorie-restricted diet or intermittent fasting, typical calorie-packed protein powders will hinder your progress. Fortagen has the lowest calories per serving at just four calories.

Insulin Response

Fortagen is a sugar-free powder that will not trigger an insulin response. Your energy remains balanced, and if you’re fasting, you’ll have a powerful tool to keep you from breaking your fast. For those trying to lose weight on a keto diet, having a zero-carb/zero-sugar protein powder with high protein per serving can make the journey a lot more comfortable.

Accelerate Muscle Growth and Recovery

Faster Recovery Time  

Fortagen is designed for increased protein synthesis post-workout. The reality is Fortagen has cracked the perfect essential amino acid profile code. EAAs offset muscular and systemic fatigue that hurt muscle gains when delivered in the right combination.

A 2017 study3 showed that supplementing with essential amino acids outperformed passive recovery and rest after varied and exhaustive exercises. Another 2018 study4 showed EAA supplementation delayed fatigue, improved endurance capacity, and prevented muscle failure compared to a placebo.

Perfect for Weight Loss

Fortagen comes in at just four calories per serving. If your goal is to lose weight, a calorie-restricted diet is a must. Ideally, you will keep your muscles while shedding the excess fat. However, muscle gains require a minimum of .7-1 gram of protein per pound of bodyweight.

If you are looking to build muscle solely from whole food protein sources, you will need to consume a lot of food.

A 2012 weight loss study5 showed that participants who received EAA supplements lost more fat and less lean muscle tissue than those using meal replacement shakes. Another study found EAA supplementation has a promising therapeutic effect6 in treating obesity.
