Shakeology, Soylent, and Isagenix Critiques and Comparability

“Hey, hope you’re doing nicely! We haven’t seen one another in years—in all probability since highschool! Loopy how time flies. We should always get collectively a while! Additionally, have you ever heard about Beachbody?”

In fact you might have. Everybody is aware of not less than one newly minted well being guru hawking the newest eating regimen drinks—Isagenix, Beachbody’s Shakeology, in addition to Soylent—on Fb or Instagram. Thousands and thousands of kilos misplaced, they are saying. Simply swap out your common lunch for a “creamy Dutch chocolate” protein shake (all of the indulgent taste *with out* the guilt!) and watch the fats soften away.

May these claims probably be true? I’ve seen tons of posts in my Fb feed, together with folks I actually know, displaying off drastic bodily adjustments in pictures earlier than and after they began their shake routine. So my anecdotal proof means that these shakes seem to work if weight reduction is your objective—however let’s do not forget that weight reduction would not equal well being. Along with this concern, these shakes are fairly costly as nicely (they will run you upwards of $400 per 30 days).

Thus, the essential questions: Are these shakes truly good for you, and are they well worth the excessive price?

The Claims


Isagenix claims its IsaLean shakes are nutritionally full meals. The model is finest identified for a 30-day system that supposedly helps you obtain optimum well being by “dietary cleaning,” a imprecise phrase the corporate says will “take away probably dangerous toxins and impurities from the physique.” There’s some sturdy proof to counsel that detoxes are mainly simply hype, since our physique’s organs are designed to remove waste of every kind, together with “toxins”—however let’s see this out.


Shakeology makes it clear that its merchandise are to not be handled as a full meal alternative, though many sellers promote them this fashion. “Shakeology, if ready as directed on the label, wouldn’t meet the caloric wants of a meal,” Group Beachbody coach Daniel Crump says, noting that individuals sometimes bulk up the shake with some sort of milk, frozen fruit, nut butter, and so forth., which might flip it right into a meal.


Soylent, then again, does declare to be a full meal in a bottle, containing “protein, carbohydrates, lipids, and micronutrients… an entire mix of every little thing the physique must thrive.” The corporate asserts that 20 p.c of your day by day diet comes packed in only one bottle.

What You’re Actually Ingesting


Isagenix’s IsaLean vanilla-flavored Shake incorporates 55 elements. Non-organic, non-grass-fed whey is the primary protein supply, which could be problematic for individuals who are delicate to lactose from dairy.

Moreover, if the cows they supply from usually are not natural or grass-fed, they’re normally being fed corn and soy, that are meals excessive in omega-6 fatty acids—our physique wants these, however in a sure steadiness with omega-3s. The present customary American eating regimen is kind of excessive in omega-6 because of corn and soy and different vegetable oils, so including extra can create an imbalance and up the chance of coronary heart illness.

The third-listed ingredient in IsaLean is sunflower oil, which is regarding, because the industrial manufacturing technique of sunflower oil tends to trigger rancidity (gross); plus it’s excessive in omega-6s.

Regardless of being a powder primarily composed of remoted vitamins with little real-food elements, Isagenix does largely use the pure types of the nutritional vitamins and minerals it consists of, slightly than low-cost, artificial variations. However there are a few objects that stand out.

Apart from pure sugars and synthetic sweeteners (fructose, maltodextrin, Stevia; quantities not listed), magnesium is listed twice in each oxide and stearate varieties. Magnesium oxide is the most affordable model and is least simply absorbed by the physique, whereas magnesium stearate is a controversial ingredient within the complement world, because of poor intestinal absorption and potential overdose points.Bioavailability of US industrial magnesium preparations. Firoz M, Graber M. Magnesium analysis, 2002, Jun.;14(four):0953-1424. (TBH, although, on condition that there are 121 mg per serving, except you’re guzzling shakes all day lengthy, overdose doesn’t seem like a danger.) FYI, magnesium in these varieties is typically used not for its dietary high quality, however to assist machine processing and preserve the elements from clumping.


There are 45 elements listed within the vanilla powder from Shakeology. Like Isagenix, this additionally incorporates non-organic, non-grass-fed whey as its predominant protein supply, so the entire similar issues might apply.

However Shakeology consists of extra precise meals of their dehydrated varieties. The elements look fairly nice on the label—chia, flax, spinach, kale, quinoa, goji berries, chlorella, maca, and so forth., with minimal different elements and no fillers. The vanilla model incorporates proprietary blends of protein, adaptogens, prebiotics, probiotics, and digestive enzymes.

Nonetheless, it does include the aforementioned whey protein (non-grass-fed), magnesium oxide, and really small quantities of B nutritional vitamins which can be primarily ineffective within the given dose (zero.5-1mg). In “different elements,” natural cane sugar is the primary on the listing (which means there’s a superb quantity of it), and Stevia seems as nicely.

And Soylent?

So precisely how a lot powdered corn, soy, and canola oil do you wish to ingest each day? All three of those elements are a part of Soylent Powder. The method of creating oil right into a powder requires maltodextrin, which is a high-glycemic synthetic sweetener sometimes derived from corn. It’s championed for its straightforward absorbability, however meaning it’s going straight into your bloodstream, which can beget a rollercoaster of spiked blood sugar, insulin secretion, stress hormone launch, and the eventual crash.

As for the remainder of its 40 elements, Soylent incorporates a number of artificial nutritional vitamins, that are primarily watered-down variations of the true factor—solely half as energetic and fewer absorbable. Additionally listed within the elements are sodium ascorbate and thiamine hydrochloride. Although pure, they’re the inexpensive types of nutritional vitamins with low bioavailability, which means that our our bodies don’t take in them very nicely. Soylent additionally incorporates different low-cost components (soluble corn fiber, and mono and diglycerides that will include trans fat), in addition to 7 grams of added sugar, and soy lecithin, which can be a priority to these nervous about food-based estrogens.

If the objective is to thrive, it’s secure to say that this drink wouldn’t be our first selection.

Who’s Hawking This Stuff Anyway?

Many—I believe we are able to hazard to say most—of the oldsters promoting these merchandise should not have a background in diet. As is typical with multi-level advertising firms, sellers typically have unrelated full-time jobs and use the complement enterprise as part-time revenue. This made me marvel simply how a lot product training sellers obtain earlier than they get their companies going.

Once I requested whether or not Beachbody supplies nurition training to coaches past the essential diet label, I used to be informed that everybody receives a instrument package that “consists of an ingredient chart detailing the person elements and what they do in your physique.” I obtained this inside PDF and name inform you that whereas there’s a chart of elements, it’s stored to a fundamental listing of “ingredient teams” with common advantages, slightly than detailed info on every merchandise.

Precisely how a lot powdered corn, soy, and canola oil do you wish to ingest each day?

In fact, some coaches have accomplished their very own analysis and educated themselves on the elements, however it’s essential to notice that the claims every firm makes and the way they’re instructed to market the merchandise usually are not evaluated by the Meals and Drug Administration, and usually are not backed up by third-party evaluations.

The Backside Line

So ultimately, is it value it to take the great elements with the possibly problematic? There are some things to think about earlier than shelling out your hard-earned money (or changing into a vendor your self). Is changing one or two meals per day with a shake financially, bodily, and emotionally sustainable to your way of life? What decisions will you make when you attain your objective and not want the dietary supplements?

For Isagenix and Soylent, which declare to be meal replacements, the shakes high out at 250 energy. It’s extra seemingly that the calorie restriction, not the shake itself, is what’s serving to alongside that weight reduction we’ve been seeing on social media. Moreover, when folks begin a brand new routine, they typically make a bunch of adjustments directly, incorporating a more healthy eating regimen and extra train of their routine—not simply shakes.

These shakes are additionally extremely processed, whatever the “superfood” elements (45-55 elements in a single 36-gram scoop), and Sarika Arora, M.D., of Aum Therapeutic Heart in Boston suggests taking a less-processed method. “Concentrate on consuming nutrient-dense entire meals as a lot as doable, and with regards to meal replacements, train warning and goal to solely use merchandise from firms which can be GMP-certified to make sure high quality, security, and efficacy.”

Soylent, Isagenix, and Beachbody declare to comply with Good Manufacturing Practices (GMP) requirements, however as of the time of reporting, none are listed as licensed. (Word, GMPs usually are not required by regulation to be licensed.) “I believe it’s all the time essential to do your homework and know as a lot as doable about what you’re consuming to guard your self,” Arora says.
