Meal replacement shakes have become a popular option for individuals seeking convenient and nutritionally balanced solutions to support weight loss, manage busy schedules, or simply ensure adequate nutrition on hectic days. These shakes provide a combination of protein, carbohydrates, healthy fats, and essential vitamins and minerals, mimicking the composition of a complete meal in an easy-to-consume format. For those on a low-carb diet, finding the right meal replacement shake can be particularly beneficial. This article delves into the world of low-carb meal replacement shakes, offering insights and reviews to help you make an informed choice.
Meal Replacement Shakes vs. Protein Shakes: Understanding the Difference
While the terms "meal replacement" and "protein shake" are often used interchangeably, it's crucial to understand their distinct purposes. A meal replacement shake is designed to provide a balanced nutritional profile, including protein, carbohydrates, fat, and fiber, to replicate a full meal. Many also contain added vitamins and minerals, either from fortified nutrients or whole-food ingredients, to help fill dietary gaps. Due to this comprehensive approach, meal replacements are often marketed for weight management, on-the-go convenience, or situations where preparing a full meal is impractical.
On the other hand, protein shakes are generally formulated with protein as the primary focus. They may contain little to no fat, carbs, or micronutrients (vitamins and minerals). The primary role of a protein shake is to support muscle recovery, enhance athletic performance, or simply boost daily protein intake rather than replacing a meal. The key difference lies in balance: Meal replacements aim to stand in for a full meal, while protein shakes are better thought of as a supplement.
The Role of Meal Replacement Shakes in Weight Loss
Meal replacement shakes can be a strategic tool for weight loss, but they are not a magic solution. Research indicates that structured meal replacement plans can be effective in reducing calorie intake, promoting portion control, and maintaining nutritional adequacy during weight loss. A recent research review revealed that individuals using meal replacements as part of a calorie-controlled diet experienced greater weight loss compared to those following conventional diets without meal replacements. This is attributed to the shakes providing a set number of calories and relatively balanced nutrients, making it easier to adhere to a calorie deficit without the guesswork involved in meal preparation.
However, the effectiveness of meal replacement shakes depends on how they are used. Registered dietitians routinely advise that meal replacement shakes are most effective as a short-term or partial substitute, such as replacing one meal a day, rather than replacing all meals indefinitely. Long-term weight management is more sustainable when meal replacements are combined with whole foods, healthy eating habits, and lifestyle changes. They can be a helpful tool for jump-starting weight loss or managing busy schedules, but they should be part of a broader, balanced approach rather than the sole solution.

Making Your Own Low-Carb Meal Replacement Shakes
Creating your own meal replacement shakes at home offers complete control over ingredients, flavors, and nutrient balance. A homemade shake can include a mix of protein (such as whey, pea, or soy), healthy fats (like avocado, nut butters, or seeds), and low-carb carbohydrates (like leafy greens or a small amount of berries) to create a balanced meal. Adding a source of vitamins and minerals, either through whole foods or a powdered supplement, can help cover specific nutritional gaps.
When properly balanced, homemade meal replacements may offer comparable nutrient profiles to commercial products while avoiding added sugars, fillers, and artificial ingredients. However, making your own meal replacement shakes requires careful attention to portion sizes and nutrient ratios to ensure you're meeting your dietary needs. Unlike commercially prepared shakes, homemade versions lack a standardized label, so it's easy to under- or overestimate calories, protein, or micronutrients. It's recommended to consult a registered dietitian when creating any type of meal replacement to ensure it truly functions as a balanced meal. Like commercial shakes, homemade versions are best used to replace one meal a day rather than your entire daily intake, ensuring you still get the variety and balance of whole foods necessary for long-term health.
Key Considerations for Low-Carb Meal Replacement Shakes
When selecting a low-carb meal replacement shake, several factors should be taken into account to ensure it aligns with your dietary needs and preferences.
Protein Type
- Whey-based: Whey protein, derived from dairy, is a complete protein containing all nine essential amino acids necessary for muscle repair, immune support, and overall health. The three main forms-concentrate, isolate, and hydrolysate-differ in processing, digestion speed, and lactose content. Whey concentrate is the least processed and contains more fats and carbohydrates, while whey isolate is more refined, lower in fat, and typically better tolerated by those with lactose intolerance. Hydrolysate is broken down into smaller peptides for easy digestion.
- Plant-based: Plant-based proteins are sourced from ingredients such as peas, rice, soy, and hemp, making them a great option if you're avoiding animal products. While some single-source plant proteins may lack one or more essential amino acids, blends can offer a complete amino acid profile. Plant proteins are naturally lactose-free and often higher in fiber, making them ideal if you're sensitive to dairy or following a plant-forward diet.
Amount of Protein
While a sedentary adult only needs 0.8 grams of protein per kilogram of body weight for basic functions, you likely need more than that, especially if you're active or looking to lose weight. Whether you're a recreationally active woman or a competing athlete, aim for around 1.2 to 1.6 grams of protein per kilogram of body weight, according to current research and recommendations. Protein helps build and repair muscle, supports the immune system, and is needed for almost all chemical reactions that take place in the body. It also helps you feel fuller and slows your digestion down when you eat meals. A meal replacement shake that provides a quarter of your protein needs, or at least 20 grams per serving, is ideal.
Calories
If you’re looking for a true meal replacement shake, choose an option with a minimum of 300 to 400 calories. Even then, you may need to supplement it with something else, like a handful of nuts, a piece of fruit, or some veggies and hummus. Shakes with fewer calories can make a great snack or breakfast if you’d otherwise skip the first meal of the day. Remember that a shake with fewer than 200 calories won’t supply your body with enough energy.

Sweeteners
Some meal replacement shakes have a lower amount of carbohydrates and added sweeteners, while others may contain anywhere from 15 to 30 grams of carbohydrates. Added sugars can range from cane sugar to fructose, but natural sweeteners such as stevia, monk fruit, or allulose are more common. Artificial sweeteners such as sucralose, aspartame, or sugar alcohols like erythritol or sorbitol can also be found, but it's best to limit your intake as they can cause stomach pain, gas, and bloating in people with sensitivities.
Other Ingredients
Some keto drink mixes contain ingredients such as the ketone body beta-hydroxybutyric acid (BHB), carnitine (an amino acid), chromium, creatine, hydroxymethyl butyrate, ECA stack, fish oil, magnesium, potassium, sodium and vitamin D. Consider products that contain natural sources of these ingredients.
Top Low-Carb Meal Replacement Shakes: A Review
Here's a look at some of the best low-carb meal replacement shakes available, considering factors like ingredients, nutritional profile, taste, and cost:
HLTH Code Complete Meal
HLTH Code Complete Meal, co-founded by metabolic scientist Dr. Ben Bikman, offers a keto-friendly meal replacement shake with a focus on metabolic health. It comes in chocolate macadamia and creamy vanilla flavors. Both options taste delicious and have a creamy texture. Even though the shake has much more protein than most of the other products in this list, don’t be concerned about that, even if you’ve heard that too much protein can kick you out of ketosis. The reality is that gluconeogenesis (the process of making glucose from non-carb sources) is demand-driven rather than supply-driven. Additionally, some studies suggest that you can enhance muscle protein synthesis by consuming fat and protein at a ratio of 1:1. While the vegan powder had a pleasant taste, even when mixed with plain water, the traditional formula mixed with full-fat raw dairy is preferable. The one big downside to this product is that most of its vitamins and minerals are from synthetic sources. As a rule, research strongly suggests that natural vitamins are superior to synthetic ones, in large part because natural forms of nutrients are more bioavailable (meaning they’re more easily absorbed and utilized by the body).
Keto Fuel
Keto Fuel is Super Body Fuel’s keto meal replacement shake, offering fewer carbs and slightly higher amounts of fat (medium-chain triglycerides) than their regular meal shakes. When mixed with almond milk, the taste is great. The only downside is that you have to let it rest in the fridge for about two hours to get the optimal taste and texture. All of the protein from Keto Fuel comes from brown rice, which is a less-than-ideal source of protein for humans because of its poor bioavailability and absorbability.

Perfect Keto’s MCT Oil Powder
Perfect Keto’s MCT Oil Powder is a great keto shake that’s relatively stomach-friendly due to its moderate amount of medium-chain triglycerides (from coconut oil). However, each serving has just 70 to 80 calories, depending on the flavor, limiting its usefulness to specific cases where you’re not actually trying to replace a meal.
Naked Keto
The unflavored version of Naked Keto contains only two simple and clean ingredients: MCT oil powder and high-oleic sunflower oil powder. However, both of these powders are made with fillers and flow agents, including inulin (a fiber that can make you bloated), sunflower lecithin, silicon dioxide and others. Naked Keto contains what’s called high-oleic sunflower oil, which has much lower concentrations of PUFAs in lieu of stable monounsaturated fatty acids (MUFAs).
Fat Fuel
Fat Fuel is slightly different than the other products on this list, in that it doesn’t market itself as a shake. All three flavors contain coconut oil powder, grass-fed butter powder and MCT oil powder as healthy sources of fat. Fat Fuel Cocoa has 0.1 grams of erythritol, a sugar alcohol that I usually try to stay away from. However, it’s such a small amount that I wouldn’t worry too much about it.
Perfect Keto’s Collagen Peptides Powder
What is like about Perfect Keto’s collagen peptides powder is that it doesn’t contain anything except hydrolyzed collagen powder (amounting to 10 grams of protein per serving) and a moderate amount of MCTs (four grams). LevelUp Grass-Fed Keto Protein Powder is neither a potent protein powder nor a keto meal replacement. However, considering its premium ingredients, it can still have a place in your keto diet as a supplement. It’s a tasty shake that’s easy to prepare, and it contains no chemicals or fillers.
Ka'Chava Superblend Shake
Ka’Chava is one of the best powder-based meal replacements thanks to its blend of whole-food ingredients. Each serving provides 25 grams of plant-based protein from yellow pea and brown rice, covering all nine essential amino acids. You’ll also get six grams of fiber, omega-3s, MCTs, antioxidants such as turmeric, adaptogens like ashwagandha, probiotics, and digestive enzymes-a full-body formula in one scoop. The flavors are smooth and drinkable with no grassy aftertaste or chalky texture. At 240 calories, it may need a boost (like fruit or nut butter) to fully replace a meal. It’s also gluten-, dairy-, and soy-free, though it does contain coconut and sesame. It also has 450 milligrams of sodium per serving, which might be a consideration for some.
Huel Black Edition Ready-to-Drink
The Huel Black Edition drink contains 400 calories, 35 grams of protein, and 27 essential vitamins and minerals per bottle. It’s made with a blend of pea protein and faba bean powder, which provides a more complete amino acid profile. Each bottle also delivers six to seven grams of dietary fiber, plus healthy fats. The added micronutrient blend of iron, zinc, calcium, vitamin D, and B-complex vitamins covers your daily needs.
Premier Protein Shake
A protein shake can have all the best ingredients, but if it doesn’t taste good, you probably won’t keep reaching for it. Premier Protein Shake offers a wide variety of flavors-from classic chocolate and vanilla to unique options like cinnamon roll and root beer float with a smooth, creamy texture with a satisfying taste that stands out in the protein shake category. However, it only has 160 calories per bottle, so it is not a complete meal replacement on its own and contains artificial sweeteners and additives like soybean oil, which may be a concern for ingredient-conscious users. The dairy-based protein is also not suitable for those with lactose intolerance or dairy allergies.
Evolve Plant-Based Protein Shake
Evolve straddles the line between snack and supplement. It’s not quite a full meal, but it’s great as early morning pre-workout fuel-especially blended into coffee when appetite is slow. Nutritionally, Evolve earns extra credit for its micronutrient profile of calcium, iron, zinc, and B12-nutrients that are often hard to get on a plant-based diet. And while pea protein is technically a complete protein, it’s a little low in methionine, which is important for tissue repair and metabolism. A simple fix is to pair it with methionine-rich foods like nuts or seeds to round out your intake.
Owyn Plant-Based Protein Drink
OWYN delivers clean, high-quality nutrition without fillers, artificial additives, or common allergens. Every product is free from the top nine allergens, including dairy, soy, gluten, eggs, peanuts, and tree nuts. Each shake uses a blend of pea protein, organic pumpkin seed protein, and organic flax oil, which all help deliver 26 grams of plant-based protein. This combination supports a broader amino acid profile than pea alone, helping to promote muscle repair, satiety, and overall recovery-all without relying on dairy or soy. The drink also includes 23 essential vitamins and minerals that support bone health, immune function, and energy metabolism. It’s a well-rounded shake that offers more than just protein.
Koia Plant-Based Protein Shake
Koia stands out as the best almond milk-based for its smooth texture and rich, nutty flavor. Each bottle comes in at 180 calories with 20 grams of plant-based protein, six grams of fats, and six grams of fiber. The protein blend-made from brown rice, peas, and chickpeas-offers a more complete amino acid profile than single-source proteins, supporting both muscle recovery and satiety. While it’s not quite high enough in protein and calories to replace a full meal, Koia is a satisfying option if you need something quick to hold you over until your next meal.
Kate Farms
Kate Farms shakes offer a plant-based, nutrient-dense solution with 16 grams of USDA Organic pea protein, 27 essential vitamins and minerals and prebiotic fiber, all packed into just 330 calories. Formulated with phytonutrient extracts from foods like broccoli, kale, berries and turmeric, these shakes are free from the top nine allergens, including dairy, soy and gluten, making them accessible for a wide range of dietary needs.
Happy Viking
Created by tennis star Venus Williams, Happy Viking shakes are a 100% plant-based option designed to support active lifestyles. Each shake contains 20 grams of protein, 140 to 160 calories and a blend of brown rice and pea protein, plus nutrient dense foods like açai, kale and pomegranate. It also contains probiotic and prebiotic fiber to support digestion and fullness.
Nutricost Organic Vegan Meal Replacement
Nutricost delivers the essentials-20 grams plant protein, organic certification, gluten-free and non-GMO profile, and zero grams of added sugar-at a notably low cost without unnecessary add-ons. The vanilla flavor is extremely subtle, and it has a very earthy flavor profile.
Ora Organic So Lean & So Clean
Ora Organic So Lean & So Clean contains no sugar, which is a rarity for a vegan powder supplement and includes over a dozen whole-food-sourced ingredients, such as acai, blueberry, broccoli, turmeric, pomegranate, and more.
Transparent Labs Mass Gainer
Transparent Labs Mass Gainer is specifically formulated as a mass gainer-a category designed to boost calorie and protein intake for those struggling to gain weight and offers about 770 calories, including more than 50 grams of grass-fed whey protein, and clean carbs from oats, tapioca, and sweet potatoes.
Huel Ready to Drink Vanilla
Huel’s Ready to Drink offers convenience along with complete plant-based nutrition in a portable bottle. The taste of this product is decent but you can definitely tell that it’s a plant-based protein (pea protein, fava bean protein) powder, which tastes significantly different from a whey. The vanilla flavor is subtle, and there is a moderate level of sweetness from the coconut sugar.
SunWarrior Lean Superfood Shake
SunWarrior’s Lean Superfood Shake is thoughtfully formulated to promote healthy, lasting weight management while still delivering vital nutrition. The vanilla flavor is extremely subtle and has a very earthy flavor profile.
Additional Considerations for Keto Shakes
When considering keto shakes, it's essential to understand that the goal of the keto diet is to live a healthier life by making smarter food choices and by helping your body’s metabolism.
Gums
Many gums are in natural products that are derived from plants, but some have the potential to cause stomach problems in people who are sensitive.
Corn
Corn has little nutritional value compared to other vegetables and fruits, and it contains certain types of proteins that your body can’t properly break down. These prolamins can lead to or exacerbate leaky gut syndrome and the growth of harmful bacteria in your gut.
MCTs
As delicious and healthy as these ketogenic shakes might be, keep in mind that consuming high amounts of MCTs can cause an upset stomach and lead to gas, bloating and diarrhea. Plus, these products will likely not keep you satiated for very long because of their lack of protein.
Where to Buy
The most convenient way to buy keto shakes and meal replacement drinks is online. If you want to leverage any discount codes, you usually have to purchase the products directly from the manufacturer’s online store. However, some of the brands I mentioned above also sell their shakes on Amazon. Walmart and Target also offer a ton of keto shakes.
