18 Shake Review - 10 Things You Need to Know

18 Shake is a meal replacement shake that promises to “naturally help to reduce hunger and lose weight fast.” 18 Shake claims to be a “luxury meal replacement” — what exactly does that mean?

It says it contains no artificial sweeteners or other unhealthy ingredients, but many competitors tick those boxes too. What is so luxurious about whey protein, we wondered?

Our research team examined 18 Shake’s “luxury” claims to see if 18 Shake is superior to its competition. The team also had concerns about some negative reviews on 18 Shake, so we have summarized everything you need to know about this product.

18 Shake can be purchased through their Official Site.

Overview

What is 18 Shake?

Let’s start by looking at what this product is, and it promises to do. 18 Shake is a meal replacement that contains:

  • Whey Protein Concentrate
  • Whey Protein Isolate
  • Fibersol-2
  • Vitamins
  • Minerals

18Shake is claimed to be an all-natural luxury meal replacement shake with “no added artificial sweeteners, soy, gluten, or unhealthy ingredients that many other meal replacements have.”

This sounds like a great promise – but we’ve seen it before. 18 Shake claims that users will experience appetite suppression and natural weight loss using a “superior dual-protein formula and potent fiber.”

Customer complaints of ineffectiveness already have us on edge here, so we have to dig a little bit deeper.

What is the 18 Shake Diet?

The 18 Shake Diet is a weight-loss plan that centers around replacing one or two of your daily meals with their nutritional shakes. The eBook gives you a dietary plan to follow while you’re using the shakes.

Though the official company says you do not have to exercise while you’re using it, they say many of their customers choose to do so to enhance their results.

We haven’t yet seen a meal replacement shake that delivers weight-loss results on its own, so we think dieting and exercising should be encouraged here.

18 Shake Ingredients

The makers of 18 Shake share the label on the official website, which we like. But we still feel the need to investigate the ingredients a bit further. We want to see what science has to say about the effectiveness of this formula.

  • Whey Protein Concentrate
  • Whey Protein Isolate
  • Fibersol-2

The 18 shake nutrition facts show that it contains only 90 calories per serving, with 1.5 grams of fat, 15 grams of protein, and 5 grams of dietary fiber, with only one gram of sugar. It also contains vitamins A, C, D, E, K, and B complex vitamins. 18 Shake also has:

  • Calcium
  • Phosphorus
  • Magnesium
  • Iodine
  • Sodium
  • Chromium
  • Copper
  • Potassium

It’s also claimed to be gluten-free, naturally sweetened, and soy free, without artificial flavors.

Whey protein isolate

Whey protein isolate is made by separating components from milk. Supposedly, whey protein is used to improve athletic performance.

Current Opinion in Clinical Nutrition and Metabolic Care concluded, “Whey proteins are a rich source of these essential amino acids and rapidly elevate plasma amino acids, thus providing the foundations for preservation of muscle mass.”

Whey protein concentrate

Current Opinion in Clinical Nutrition and Metabolic Care concluded: “whey protein may affect metabolism and muscle protein synthesis.”

Fibersol-2

A study from Nutrition Research shows that just 10 g of fiber with every meal can help with satiety. “This study demonstrated that 10 g Fibersol-2 with a meal stimulated production of satiety hormones and enhanced satiety.”

18 Shake Benefits

18 shake weight-loss results will vary from person to person, and according to our research, some people seem to not be losing the weight they had hoped for.

If you don’t do anything else but replace one to two meals a day with the shake, you won’t see the weight-loss you would if you dieted and exercised with the product.

It’s important to make sure you’re still getting enough calories for your body because if not, you can slow your metabolism down, which will lead to weight gain despite not eating as much as you’re used to.

Current Nutrition and Food Science linked the use of meal replacement shake with weight loss. Meal replacement plans for weight management suggests that these types of interventions can safely and effectively produce significant sustainable weight loss. However, “the evidence for a clinical efficacy is not strong enough to make strong recommendations with respect to a specific dose and the duration of supplementation.”

Aloe vera

The gel from the aloe plant is often used as a topical treatment for sunburn, claims a study by the British Journal of General Practice. It’s thought to have some health benefits from oral use as well.

Flavors

18 Shake Flavors

Currently, there are only two flavors to choose from:

  • Chocolate
  • Vanilla
  • Cookies & Cream
  • Strawberry

We are not sure if they are planning on adding additional flavors in the future, but because they don’t use any artificial flavors, additives, or preservatives, it doesn’t seem likely. However, they do provide healthy recipes you can use to change the flavor of your shakes while still using the base flavors.

18 Shake Recipes

You can find several 18 shake recipes on the official website. These are intended to make the shakes more exciting, so you don’t get bored with the same flavors.

Recipes include:

  • Apple pie shake
  • Super green smoothie
  • Blueberry bluster shake
  • Chocolate strawberry blast
  • Chocolate coffee protein shake
  • Creamy peanut butter shake

Many of the recipes make two cups worth of shake and can be prepared in 10 minutes or less, using ingredients like ice, milk, applesauce, bananas, and natural sweetener.

Cost

  • One bag of 18 Shake – $79.98 (on sale for $47.99)
  • Two bags of 18 Shake (free bag of 18 Shake and the 18 Shake eBook) – $179.98 ($59.99 per bag)

Side Effects

18 Shake Side Effects

There’s no mention of 18 Shake side effects, but there’s a chance some may notice side effects from 18 Shake ingredients, including:

  • Nausea
  • Upset stomach

18 Shake Vs.

If you search around for meal replacement shakes, you’ll find that there’s no shortage of alternatives out there. We want to take a minute to look at some of the other options out there, as well as a side-by-side comparison to some popular competitors.

18 Shake vs. Plexus 96

Plexus 96 whey protein shake contains 12 packets for $35.95, making it a much more affordable option. It also contains 15 grams of whey protein but doesn’t mention isolate.

Each serving is only 100 calories and is also gluten-free and 100% vegetarian. It contains 20 vitamins and minerals and only has one gram of fat – and no sugar. 18 Shake still wins on protein, since Plexus provides no dietary fiber, but the price alone is enough for us to suggest Plexus 96.

18 Shake vs. Shakeology

Both of these shakes are among the most popular meal replacement options available on the market today. One serving of Shakeology has 140 calories, so 18 Shake wins in that category.

Shakeology only has one gram of fat to the 1.5 in 18 Shake.

18 Shake wins in the sugar content, since Shakeology has 10 grams per serving.

Shakeology has 17 grams of protein, but their protein comes from pea protein, which is a vegan source. Both shakes use whey protein. But Shakeology wins for the variety of protein they offer.

18 Shake beats Shakeology in terms of fiber content, with 15 grams per serving, compared to Shakeology’s four grams. That’s among the highest content of any protein shake on the market.

18 Shake vs. GNC Lean Shake

When you compare 18 Shake to GNC Lean Shake, you’ll find that the serving size for GNC Lean is nearly 1.5 times bigger. But, it contains twice as many calories, four times the sugar, only 9 grams of protein, and only 8 grams of fiber.

GNC Lean shake is vegan, but both are GMO and gluten free. GNC has a wider range of flavors and costs less than 18 Shake, so we’ll have to lean towards GNC here…

18 Shake vs. IdealShape

IdealShape comes in 15 flavors and is more affordable. Flavors include: Chocolate coconut, chocolate, vanilla, strawberry, banana cream pie, chocolate peanut butter, cookies n cream, vanilla chai, mint chocolate, eggnog, mocha, salted caramel, chocolate cream pie, superfood blend dark chocolate stevia sweetened, orange cream, cinnamon bun, key lime, and vanilla superfood blend stevia sweetened.

It uses a different hunger blocker. Where 18 Shake uses Fibersol, IdealShake uses Slendesta – but 18 Shake contains more protein, less sugar, and fewer calories. Slendesta is a potato protein extract.

18 Shake vs. Herbalife

Herbalife has a bit smaller portion size, at 25g compared to the 27.27g in 18 Shake. It contains less protein – only nine grams. It also contains less fiber, at only 9 grams, but this is a hefty fiber dose compared to many other competing shakes.

One container of Herbalife contains 30 servings. Flavors include banana caramel, French vanilla, dulce de leche, orange cream, vanilla with non-GMO ingredients, mint chocolate, Dutch chocolate, wild berry, cookies n’ cream, pina colada, cafe latte, and kosher vanilla. Herbalife is priced at around $40/container.

Not only is Herbalife more affordable, but offers a ton of flavors on top of it, making this our choice out of the two.

18 Shake vs. Isagenix

Isagenix has a bigger variety of flavor options, like Dutch chocolate, french vanilla, strawberry cream, rich chocolate (dairy free), vanilla chai (dairy-free), natural creamy vanilla (kosher), PRO Natural Chocolate, PRO Natural Vanilla, PRO French Vanilla, PRO Strawberry Cream, and Pumpkin Spice. Pumpkin Spice is a seasonal flavor, with other seasonal flavors released accordingly.

Isagenix has several types of shakes. They have one that uses whey protein like the 18 Shake, but they also have a dairy free range that uses plant-based proteins. The dairy-free shakes are also soy and gluten free.

Isagenix’s portion sizes are much larger – 18 shake is 27.27 grams, where Isagenix’s options are 61g and 69g. With that bigger portion size comes more calories, but if we cut them down to the same size roughly, Isagenix still has more sugar, more fat, and less fiber.

The protein content is about the same. If you use the IsaLean version, you’ll get about 12 grams of protein. The other product line is geared toward those who want to gain muscle/weight, so you get a bit more protein at 18 grams.

18 Shake vs. 310 Shake

310 Shake is $68.00 a bag, and it contains 28 servings. It is also free of soy, sugar, and gluten contains 15g of high-quality plant-based proteins and is naturally sweetened. It only contains five grams of fiber.

Like most other alternatives to 18 Shake, 310 Shake has a wider selection of flavors to choose from, including:

  • Mocha
  • Salted Caramel
  • Chocolate
  • Vanilla
  • Strawberry
  • Vanilla Chai

The proteins come from peas, brown rice, and hemp. 310 also contains probiotics. It has one gram of fiber to 18 Shake’s 1.5 – It’s obvious who the winner is here.

What Users Are Saying

“The taste of this product was horrible. The consistency was very think and frothy no matter what I used to mix it with.”

“I really like 18 Shakes because it keeps me full for a few hours. I can’t believe it keeps me so full having only 90 calories. The taste is just okay but as I have tried to eliminate sugar from my diet, I have found myself enjoying the taste much more. I think it works great!”

“It was ok. Not what I was expecting but maybe I didn’t understand the product.”

18 Shake Ingredients
Bottom Line

The Bottom Line on 18 Shake

Will this shake take you to the next level, delivering weight loss, appetite suppression, energy, and increased performance? We highly doubt that it will provide significant benefits unless you’re dieting and exercising along with taking it.

We liked some of the research behind the ingredients, but there were too many negatives for us to support this supplement honestly.

18 Shake Cons:

  • Too expensive
  • Customer comments on lack of results
  • No research on the formula

Long-lasting weight loss requires changes to lifestyle and habits, but sticking with these changes can be a bit difficult. That’s why we think technology can play a big part in helping you stay on track to lose more and keep it off.

Among the best weight-loss apps we’ve found this year is Noom. Noom is different. It was created by doctors, offering a unique look at weight loss that’s been clinically proven to help users lose more weight and keep it off.

Plus, Dietspotlight readers can access a 14-day trial of Noom to see what real weight-loss support looks like.

    IS ONE PACKAGE A ONE MONTH SUPPLY?? IN OTHER WORDS, THE 3 PACKAGES WOULD BE FOR 3 MONTHS OR NO?? NO WHERE CAN I FIND WHAT IS IN THE PACKAGE??

  • Wayne (Verified Purchase)

    I gave this product time to work, and when it did not give the promised benefit of weight loss, I asked for my money back. I had unopened bags to return, as well. They refused to give me a refund. AVOID this product! It is an overpriced drink mix that does not give the promised results. You are probably better off getting a weight loss drink mix from the grocery store, or some other product Save your money and don’t waste your time on this. If I could, I would only give it a half star, only because it seems to have some nutritional value.

    I ordered the shake18 after doing some research and I was very disappointed. First off I personally do not like the Vanilla flavor, but I can deal with that. The part that upset me was that 30 minutes after taking the shake in the morning I was hungry. It didn’t help with controlling my hunger and to be honest I saw nothing positive after the first week.

      Hi Sandra, you might need to lean towards more of an appetite suppressant product if that’s the case. One product that helps with suppressing appetite is Dietspotlight Burn; you should check that one out as well!

  • Best shake EVER
    Melyssa (Verified Purchase)

    I’ve been using 18 shake as needed for breakfast and sometimes a lunch replacement. I keep it at work so I don’t have to worry about bringing a lunch. My use is inconsistent and yet it still works. It’s the absolute best shake I’ve tried for killing hunger pangs fast!! I have the chocolate and find the sweetener to be off-putting. I put a scoop into my coffee and still use a splash of creamer and it’s my favorite way to drink it now, it really cuts the aftertaste and keeps me feeling full for hours. Going to try another flavor next time I order, hoping the aftertaste will be better.
