Low carb meals or ketogenic diets are increasingly becoming popular for their weight loss benefits. And low carb meal replacement shakes are certainly a big part of that picture! In fact, studies have shown that they are more effective in weight management than low-fat and low-carb meals in the long term.

Additionally, following low carb recipes daily can be challenging, particularly for busy professionals who have to eat on the go. If you’ve lived through such struggles, you’ll understand the importance of having a ready-made, low carb meal shake that provides the necessary nutrition and helps you stay on track.

Low carb meal replacement shakes are a fast and ideal way to enjoy a healthy, low-carb snack or meal on the go. But with so many options and endless promises, how do you choose the right one? Worry not – we’ve got you covered.

But first…

What to Look For In Low Carb Meal Replacement Shakes

Total Calories

The ideal low carb meal replacement shake should have enough calories to give you the energy boost you need throughout the day. Anything between 300 and 600 calories should be enough to keep you going without going over the top. And even though it’s low carb, it’s still a good idea to always keep your eye on calories when focusing on weight management!

Protein Content

A carb-friendly meal replacement shake should have a reasonable amount of protein. That’s because your muscles need it for strength and recovery. 

Look for a meal replacement shake with anything between 15 to 35 grams of quality protein per serving.

Net Carb Content

While your goal is to limit your carbohydrate intake, that doesn’t mean you should avoid it all together. You might see some low carb meal replacement shakes with high amounts of carbs on the label, but sometimes most of it is just fiber.

For example, if a shake has 21 grams of carbs, but 19 are from dietary fibers, it’s still considered low-carb. Your body doesn’t use dietary fiber for energy, so it will not kick you out of ketosis. Just subtract the total fiber content from the total carb count to get the net carb content, which in this case is 2 grams.

Fat Content

With reduced carbs, your body’s primary source of energy is fat. Your ideal low carb meal replacement shake should have high-quality fats to help you stay in a ketosis state. But you don’t want too many fat calories, or that can defeat the goal of weight loss and weight management.

Other Nutrients

Your low carb meal replacement shake should also have other essential nutrients that support your fitness performance, health, and recovery. They may not have to be in large quantities, but every bit counts. Such nutrients include:

  • Ketone body beta-hydroxybutyric acid (BHB)
  • Hydroxymethyl butyrate
  • Chromium
  • Carnitine (an amino acid)
  • Creatine
  • ECA stack
  • Magnesium
  • Fish oil
  • Sodium and vitamin D
  • Potassium

Additionally, the ingredients in your preferred low carb meal replacement shake must be from natural sources. For instance, you can choose one with medium-chain triglycerides (MCTs) from coconut oil over MCT powder.


Of course, you don’t want a meal replacement shake that taste so awful you can’t even stomach it. If it tastes terrible, you’re just going to get fed up with it and look for something else.

While you can’t tell a great test just by looking at a product, you can trust customer reviews. Other users who have tried the shake can provide valuable insight into the taste and texture of a keto-friendly meal replacement shake.

1. PhenQ Complete Meal Shake – Best Overall

PhenQ Complete Meal Replacement ShakeBrand Overview

PhenQ complete meal shake is arguably the best carb-friendly shake on the market. It’s a product of WOLFSON BRANDS (UK) LIMITED, a health and fitness company that has built a reputation for extensive scientific research and development. 

The UK-based brand has been in the supplements industry for about 15 years now, providing superior-quality products that are both convenient and healthy.

Its latest PhenQ complete meal shake has lived up to the company’s reputation, as it’s made with superior-quality ingredients. So what exactly has been the drive behind this shake?

Highlighted Features:

  • Seven servings per bag
  • Only trace amounts of carbs
  • 269 total calories
  • 13 g of healthy fat
  • 16 grams of whey protein concentrate
  • 13 essential vitamins and minerals
  • 38 mg of DigeZyme Enzyme complex
  • Sugar-free
  • Gluten-free
  • Non-GMO
  • Vegan and keto-friendly




PhenQ meal shake is not your average run-of-the-mill meal protein shake. It’s a complete shake containing the best of everything. The best part is that they are all-natural, without fillers or artificial fillers and ingredients.

The shake contains the right balance of protein, low carbs, and fats to help you stay in a ketosis state while fueling your body with essential micronutrients. For instance, 13g of high-quality, healthy fats provide energy while helping you burn fat.

Another wonder ingredient in this PhenQ complete meal shake is the CARB10, a patented healthy, low-glycemic carbohydrate blend. It’s derived from premium pea starch and improves digestion and absorption of complex carbs without spiking your blood sugar levels.

The whey protein concentrate helps provide the body with quality protein that’s easy to digest. It also contains a rich complete amino acid profile that helps improve satiety, builds lean muscles, and supports weight loss & muscle recovery.

PhenQ complete meal shake comes in three delicious flavors to keep you motivated. You can choose from Vanilla, Chocolate, or Strawberries & cream and enjoy a tasty shake.

Best Meal Replacement Shakes for Taste


PhenQ complete meal shake is available on the brand’s website for $20.95 per bag for a one-time purchase. If you choose the subscription model, you can save 10% on the price.

Customer Experience

Before buying any new product, it’s always advisable to go through customer reviews. That’s the only way to know what other users feel about it before you commit your money.

We did the same for PhenQ complete meal shake and found that most users are pleased with it. Unfortunately, the brand website offers very few customer reviews, so we went through third-party sources.

As far as customer experience is concerned, it’s clear that PhenQ’s complete meal shake passes the test with flying colors. Most users we found on Reddit have expressed their satisfaction with this product.

In fact, one reviewer wrote, “This shake is great. The taste and texture are perfect. I feel full after drinking it, and I can see a difference in my energy levels.” 

Another one on Trustpilot said, “I have lost about 30 lbs in 3 months. I started at 285, and now I’m 253, which is awesome. I have to say that I combined it with a carb diet. It helped.”

We also saw a few negative reviews, with most complaining about the lack of timely response. However, the company reached out to them and resolved their issues. Overall, the customer experience has been quite positive with this product.

2. Instant Knockout Complete Meal Replacement

Instant Knockout CompleteBrand Overview:

Another stellar product that has been making headlines is the Instant Knockout Complete Meal Replacement. And it’s not just hype. It actually delivers on its claims. It’s a perfect low carb meal replacement shake when you’re on the go, but still want to manage your carbs.

This low-carb meal replacement shake is a product of Roar Ambition, a UK-based supplement company. Founded in 2014, the brand has risen to prominence in the fitness industry thanks to its high-quality and well-thought-out product line. The Instant Knockout Complete Meal Replacement is one such product.

Highlighted Features:

  • 14 servings per container
  • 400 calories
  • 13 g total fat
  • 35 g plant-based protein
  • 35 g total carbohydrates with
  • 13 g dietary fiber and
  • 3 g total sugar
  • 26 essential vitamins and minerals
  • 12mcg chromium
  • Keto-friendly
  • Vegan-friendly




Roar Ambition understands the three basics of a healthy body: strength, muscle mass, and weight loss. But it’s not all about low carbs. The brand also takes into account the importance of other nutrients.

They have designed Instant Knockout Complete Meal Replacement as a complete meal to fill those nutritional gaps and provide the body with adequate energy and protein. For example, the protein from pea and soy comes with a balanced amino acid profile that improves muscle synthesis, reduces body fat, and enhances recovery. Plus, the 26 essential vitamins and minerals offer hormonal balance and boost your immune system.

The meal replacement shake provides micronutrients extracted from chia seeds, golden flaxseeds, and other natural sources. They are excellent sources of Omega-3 fatty acids, calcium, manganese, and dietary fiber.

Unlike PhenQ Meal Shake, this one comes with only one flavor: Vanilla. However, it’s delicious enough without any chalky aftertaste.


Instant Knockout Complete Meal Replacement’s 14 servings pouch retail for $59.00 for a two-week supply. The one-month package with 28 meals goes for $118.00 with free shipping in the US and the UK. The brand doesn’t offer a subscription-buying model.

Customer Experience

Unfortunately, the brand doesn’t offer much info on user reviews on its website. However, we saw a few comments on Reddit, Facebook, and Trustpilot. Most of them were positive with praise words like “amazing,” “works great,” and “energy boost.”

One user on Reddit said, “I’ve been using this product for the past three weeks, and I have to say that it has helped me a lot. I see results already and feel more energetic throughout the day.”

Another one said, “Marketing BS aside, it looks interesting. Nothing groundbreaking but a solid recipe, as far as I can tell. Relatively low fat.”

And the positive feedback did not stop there. There are tons of publications from independent sites that reviewed the product, and they gave it a thumbs up. The only concern we saw was the price. Some people found it too expensive even though it works great.

3. Ample Original: Low-carb Meal Shake

Someone by the name of Tammy P said, “Delicious keto! The chocolate is delicious, and it makes me feel perfect. Mixes in the water much better than any other keto mix I have tried, and it has enough fat to be keto. Often I find so-called keto products have a lot of sugar. This one is true for keto. Highly recommend it. I have it delivered monthly in large sizes to save on the environmental impact of several smaller containers.”

User reviews are equally positive on Amazon, with customers raving about its “amazing,” “works great,” and “energy boost.” The product has a 3.9/5 star rating with over 120 reviewers. 81% of them were three stars and above.

The primary concern was about the price. While most people loved the six-pack concept and the quality of the product, some felt it was too steep.

4. HLTH Code Complete Meal

One reviewer wrote: “They are filling. For someone with type 2 diabetes, they are great” Another one called Jenese M “This is truly a winning meal on all fronts. As a newly diagnosed diabetic determined to beat this disease without medication, I have carefully monitored every meal for its impact on my glucose levels. HLTH code is delicious and satisfying while keeping its negligible impact on my glucose levels. I have energy and clarity, but I don’t crave sugar which I have eradicated from my way of eating. I’m so glad I found this product.”

There were very few negative reviews. The ones we saw revolved around damaged packages, a minor issue that the customer service team fixed.
