best keto meal replacement shakes

You’ve read the diet blogs, created your Instagram vision board, and memorized the mantra for living life the high fat, low carb way.  

You’ve finally found your groove on the keto diet, and you’re a lean, mean, fat-burning machine - except when you’re not because you had take-out the other night,  which was a far cry from the high fat, low carb meals your body needs to maintain a keto diet. 

If this sounds like your life, don’t fall victim to the ketosis roller coaster.

There is a better way for those times you just can’t get a properly prepared meal, and it’s called keto meal replacement shakes. 

Not to be confused with its older sister, protein powder shakes, which have been on the market for ages, keto meal replacement shakes (when done right) can be a healthy, satisfying, full meal replacement that your body will love.

The Skinny on Keto Diets & Meal Replacement Shakes

With a ketogenic diet, the critical balance between high fat and low carb is everything to your success.  When done right, a keto diet will make a fundamental change to the way your body creates energy, by using fat to fuel your body instead of carbs to send your body into a fat burning frenzy called ketosis.  While keto diets are not for everyone, the raging popularity of this diet continues to grow with a force and every day new products are developed specifically catered to the keto dieters’ market.

For those on a keto diet, finding foods that keep your body in a constant state of ketosis is the holy grail.  But just one misstep or making small mistakes on the keto diet with foods that are slightly higher in carbs or with hidden sugar contents can throw you right off the wagon, forcing you to start your diet over again and waste time and effort in the process.

That’s why the evolution of the keto meal replacement shake has become so popular.  With one simple keto-friendly shake (ok, simple is quite the understatement, as these things come packed to the brim with nutrients), you can keep your body in a constant state of ketosis and can give your body tremendous benefits, without the time or the hassle of cooking an entire meal.  

Keto meal replacement shakes, when done right, offer an entire meal’s worth of perfectly calculated calories, fat, and protein to fuel you with energy but keep you in a state of ketosis.

How to Pick the Right Keto Meal Replacement Shake

Now the most important thing to understand is that not all keto meal replacement shakes are created equal.  You’ve got to learn to look beyond the deceptively healthy sounding names of some of these products and look at the actual ingredients on the back. We’ve done the research and while many keto-friendly shakes boast incredible benefits like high level fat burning, improved energy levels and mental focus, and even healthier skin, hair and nails, the most critical factors you need to look at when choosing a keto meal replacement shake are:

Total Caloric Value

Remember, you are trying to effectively replace an entire meal’s worth of calories.  In this case, low calorie products are not your friend because they will only leave you feeling hungry and unsatisfied, causing you to overeat later.  Instead, aim for shakes that include between 400- 600 calories per serving for a drink that will help you burn fat but still properly satiate your hunger.   

Protein Content

Aim for keto shakes that include a good serving size of protein, as these bad boys are critical to building lean muscle and will keep you feeling satisfied longer.  However ensure that you are considering your protein intake for the day, as studies have shown that too much protein can be potentially harmful to your health.

Fat Content

Fat is your new best friend on a keto diet, because it serves as your fuel and the main energy source for your body.  During ketosis, 75% of your calories comes from fat, so ensuring your keto meal replacement shake has ample premium, high fat is essential.

Net Carb Count

Carbohydrates are the virtual enemy of a keto diet, so ensuring the carb count is low in your keto shake is critical.  But as you read the labels on many of these keto-friendly shakes, don’t be alarmed at the amount of carbs listed. Most keto meal replacement shakes contain high amounts of fiber, which helps maintain healthy digestion, but automatically increases the amount of carbs in turn.  Therefore, what you need to do is be sure to calculate the total net carbs in order to properly evaluate how many carbs your keto shake will actually have.

Flavor Source

The market is now full of keto meal replacement shakes with delicious flavors like salted caramel, chocolate brownie, and French vanilla latte.  And while we all want our keto shakes to taste good, it is essential to understand where all that flavor is actually coming from. It’s great that the label says “sugar-free”, but choosing products that use natural sweeteners like Stevia is far better than shakes sweetened with sugar alcohols (like Erythritol), Xantham Gum, or Corn Fiber.

Our Top Picks for the Best Keto Meal Replacement Shakes

Now that you know what will make or break your success using a keto meal replacement shake, let’s look at our top picks.  We ranked these keto shakes according to the most popular attributes keto dieters look for, including natural ingredients, flavor, convenience, and more.

Ketologie Chocolate Keto Protein Shakes are one of the most popular keto protein shakes not only because they do their keto magic to help you lose weight, but because these shakes also rank very high for its amazing taste and flavor.  

Packed with essential vitamins and minerals, Ketologie Keto Shakes help you kickstart your ketosis and burn fat all day while feeling alert and energetic.  Made with natural ingredients like coconut oil, sea salt, and grass-fed bovine collagen protein, these shakes make staying keto a breeze with the right macro ratio of 75% fat, 20% protein, and less than 2% net carbs.

While it’s available in just three ordinary flavors, chocolate, strawberry, and vanilla, each flavor is anything but ordinary because they deliver an incredibly smooth, rich taste that is neither over the top sweet nor gives you that common chalky, gritty feeling in your mouth as many shakes are known to do.

However, this great flavor does come with a price, and we don’t just mean more money (although it is more expensive than many of its competitors).  While it meets the standard macro ratio to achieve fat burning status, the Ketologie Keto Shake is higher in net carbs than most shakes (7 net carbs per serving) and while sugar-free, actually contains sugar alcohols (Erythritol), Xantham Gum and Corn Fiber.

  • These shakes are quite expensive compared to other keto powders
  • While sugar-free, Ketologie shakes do include sugar alcohols which can impact fat burning

Like the name indicates, the Perfect Keto Chocolate Protein Powder with Collagen Peptides really does seem like the perfect shake, because it combines all the benefits you look for in a keto protein powder, but with the bonus of collagen peptides to deliver tremendous benefits for your entire body. 

What makes this protein powder stand out is its all-star line-up of collagen, MCT oil powder, and acacia fiber.   We’ve all heard that collagen is good for the skin, however, what most of us don’t know is that collagen is the most important structural protein in the human body.  Perfect Keto packs 10 grams of this powerful protein in each serving, which helps offer incredible benefits like promoting a healthy gut and digestive system, strong joints, and bones, as well as glowing skin, hair, and nails.  Perfect Keto’s collagen peptides even offer anti-aging benefits. 

Perfect Keto also boosts energy, with a powerful combination of MCTs (medium-chain triglycerides) and acacia fiber, which is metabolized into ketones to give you a boost of energy rather than a boost in blood sugar levels, as many of its competitors tend to do.

Perfect Keto comes in three classic flavors (plus one, unflavored shake) including chocolate, vanilla, and salted caramel.


  • Perfect Keto doesn’t have any artificial ingredients, flavors, or chemicals
  • Features Collagen Peptides originating from 100% Grass-fed Cattle, which offer additional bonus benefits of healthy bones and joints, skin, nails and hair

  • Perfect Keto is a great add in to smoothies, shakes, or coffee

  • Perfect Keto is pricey compared to other protein powders, particularly since you can’t use it as a meal replacement drink on its own
  • Contains MCTs, which are beneficial to fat burning but can cause some gastrointestinal distress for people, especially beginners
ketolife meal shake

Top Notch Nutrition Keto Collagen Protein Powder is a unicorn among keto shakes because of its unique blend of 3 powerhouse fats - Avocado Powder, MCT Oil Powder, and Grass Fed Butter Powder.  Almost all its competitors feature one or two fat sources, but Top Notch Nutrition gives you three to turn your body into a fat burning machine.

Top Notch Nutrition shakes not only offer high fat and high protein servings in every scoop, it also boasts less than 1 net carb per serving, which is one of the lowest in the market.  They’ve used stevia leaf extract to sweeten the chocolate flavor, which makes it taste good, although not as rich or smooth as some of its competitors.

Wrap Up

While we’ve highlighted some excellent choices for keto meal replacement shakes in this buyer’s guide, like the popular Ample K Ketogenic Meal Replacement Shake, you can be confident in keeping up with your keto groove as long as you take the time to read your labels.

Select products with more ingredients that come from plants and less that were manufactured in one.  Remember to do the math to ensure your shake is adding the right ratio of proteins and fats, without tipping the balance in favor of hidden carbs.  

Most of all, make sure your keto shake can actually do its job and replace your meal, rather than only serve as a delicious snack, and you will be well equipped to curb hunger and supply your body with the high fat, low carb sustenance it needs.
