Isagenix IsaLean Shake Review: Does it Work?

According to the Isagenix website, IsaLean Shakes “contain superior nutrition compared to other meal replacement shakes on the market” and are designed to “take your health and performance to new levels.” Powerful words indeed; but words aside, the big question is, does the Isagenix shake work or not? In this review, I’m going to look at the clinical research and ingredients in the IsaLean Shake. I’ll rip away the Isagenix distributor hype, try to sort fact from fiction, and hopefully along the way help you better decide if the IsaLean Shake is right for you.

 

IsaLean Shake Ingredients

According to the product website, one Isagenix IsaLean Shake (Dutch chocolate flavor) has 240 calories per packet and the following nutritional information:

240 calories
Calories from fat = 55
Calories from saturated fat = 20
%DV
Total Fat   6 g9%
Saturated fat  2 g10%
Trans fat  0g
Polyunsaturated fat  0.5g
Monounsaturated fat 3g
Cholesterol  45mg15%
Sodium  265 mg11%
Potassium 430 mg12%
Total carbohydrate 24g8%
Dietary fiber  8g32%
Sugars  11g
Protein  24g48%

 

DV = daily value. DV based on eating 2000 calories per day

Tip. The easy way to read a food label in the US is to remember these two facts about the daily values (DV):

  • When you see 5% or less, it’s low in that nutrient.
  • When you see 20% or more, it’s high in that nutrient.

Looking at the basic nutrition label for the product, we can say that the Isagenix Lean Shake is high in protein. Its 24 grams of protein provides 48% of the body’s protein need per day (assuming you are eating 2,000 calories per day).IsaLean shake

The shake is also considered high in fiber because the 8 grams it provides is 32% of the fiber we should have in a day. The fiber (and protein) likely help people feel full longer—so that is good.

How Much Fat Is in the IsaLean Shake?

The IsaLean Shake is 22.9% fat, so it is high in fat. I got this by dividing the fat calories (55) by the total calories (240) X 100. In other words, 55/240 X 100 = 22.9% fat. This is a high-fat food because it’s more than our “20% or more is high” rule.

Note. As a rule, most healthy people should consume less than 30% of total calories in fat in a day. If the IsaLean Shake is the “worst” thing you eat, you are ok, because it only makes up 22.9% of the 65 total grams of fat of our daily recommendation (if we eat 2,000 calories per day).

Now for saturated fat. The shake has 20 calories coming from saturated fat. So, doing the same math as before, 20/240 X 100 = 8.3% saturated fat. So, the IsaLean Shake is neither low (less than 5%) or high (20% or more) in saturated fat. Putting this in better perspective—people should aim for not more than about 15 grams of saturated fat per day. One IsaLean Shake provides 2 of those 15 grams. Overall, I’d say it’s not too bad.

Isagenix distributors will point out that the saturated fats in IsaLean Shakes come mostly from medium chain triglycerides (MCTs) that come from coconut oil. These are fats that the body processes differently and as a result, they are less likely to be stored as fat and more likely to burned for energy. This might help people to lose weight―and there is some evidence of this too.

Many people say that MCTs are healthy fats, but in all due respect to those individuals, I must point out that more research is needed on this issue. For more on MCTs, see this review.

 

IsaLean Shake’s Other Ingredients

Below the Nutrition Facts Label are the other ingredients in the IsaLean shake. There are a LOT of ingredients. Fortunately, ingredients in the US are always listed in order from the most to the least so we can see which ingredients a product has the most of. So, reading from left to right, the label indicates that one packet of the Isagenix IsaLean Shake has the following ingredients:

Myo-IsaLean Complex™fructosenatural Dutch cocoa powder
isomaltooligosaccharide

vitamin B1 (thiamin hydrochloride)folate (folic acid)

 

The Myo-IsaLean Complex™ is composed of: whey protein concentrate (undenatured), milk protein concentrate (undenatured), and low-heat nonfat dry milk.

The Enzyme blend is composed of: lactase (from Aspergillus oryzae), lipase (from Rhizopus oryzae), cellulase (from Trichoderma longibrachiatum), invertase (from Saccharomyces cerevisiae), protease (from Aspergillus oryzae), amylase (from Bacillus subtilis), bromelain (from Ananas comosus), papain (from Carica papaya), and acid stable protease (from Aspergillus niger).

 

Looking over the ingredients in the IsaLean Shake, I can make these general statements:

  • The enzyme blend won’t help weight loss. There’s no evidence for this.
  • The second ingredient in the list is fructose, for those who consider this.
  • I believe most of the shake’s 8 grams of fiber come from mostly from xanthan gum and flax.
  • I don’t know what the “natural flavors” are.
  • It contains an ingredient called isomaltooligosaccharide powder. Isagenix calls this a prebiotic.

Prebiotics are basically the food of probiotic bacteria. That said, prebiotic supplements are not needed.

  • The Myo-IsaLean Complex is an invented word. It’s a combination of whey and casein proteins, which are found in milk. Whey protein is a good source of branch chain amino acids, which are popular in the world of exercise. The casein protein is absorbed slower than whey, which I’m guessing is present in the hopes that it will supply muscles with a steady stream of amino acids over a long period of time, in the hopes that this might enhance muscle growth. The prefix “Myo” refers to muscle, but I’m not aware of any evidence that the Myo-IsaLean Complex of protein builds or maintains muscle better than other forms of whey and casein protein.

 

Isagenix Research

Now, let’s talk about the research on the Isagenix Lean Shake. I searched online as well as the isagenixhealth.net website and found two studies on the shake that I will summarize below:

 

Study #1. A study published in 2012 in the journal, Nutrition and Metabolism titled Improvement in coronary heart disease risk factors during an intermittent fasting/calorie restriction regimen: Relationship to adipokine modulations. Here is the summary of the investigation:

  •  Fifty-four overweight women were randomly put on either a liquid intermittent calorie-restricted diet or a food-based calorie-restricted diet for 8 weeks. The liquid diet consisted of two Isagenix IsaLean shakes per day.
  •  For this program, the women ate less calories for the first 6 days and on the 7th day, consumed only water and 120 calories of juice powder.
  •  On the calorie-restricted days, the women consumed an IsaLean Shake for breakfast and lunch and ate a 400–600 calorie dinner. This means that on their calorie-restricted days (6 days of the week) the women were eating between 880 and 1,080 calories per day in 3 meals. This is less than the average person eats per day.
  •  The women in the food-based diet were instructed to reduce their calories by 30% of normal in the 3 meals per day they were to eat. On the 7th day, (fasting day) they also were to consume only 120 calories.
  •  Both groups met with a registered dietitian who instructed the women on how to eat healthy.

 

Results:

  • Greater reductions in body weight and waist circumference were seen in those getting the IsaLean Shakes.
  • After 8 weeks women in the IsaLean shake group lost about 8 lbs. Those eating food lost about 6 lbs.
  •  Significant reductions in fat mass were seen in those who used the IsaLean Shake compared to those who did not use the shakes (about 6 lbs lost vs. about 4 lbs).
  •  Significant reductions in total cholesterol and LDL were seen in those getting the IsaLean Shake.
  •  Significant increase in LDL particle size (this is good) was seen only in the Isagenix Shake group.
  •  Both groups saw significant reduction in small particle-sized LDL molecules (this is good).
  •  Significant reductions in leptin, IL 6, tumor necrosis factor, homocysteine, and IGF1 were significantly lower in those getting the IsaLean Shakes.
  •  CRP, a measure of cellular inflammation (and a marker for heart disease), did not change in the the Isagenix Shake group. Interestingly, CRP did decrease a little (non significantly) in the group who just dieted.

 Study Problems

1.  Only women were in the study. What about men? Its possible different genders react differently.

2.  The researchers did not track calorie intake. I feel this is the biggest problem for the women who did not get the IsaLean Shake. In other words, how do we know they ate the same calories as the women who drank the shake? We don’t.

3.  The participants knew who were getting the shakes. Since the women were aware of who got the shakes, it’s possible those women may have acted differently (ate fewer calories on purpose, for example) than the food-only group. The food-only group should have gotten a placebo/zero-calorie shake to eliminate this possibility.

    4.   The study was funded by Isagenix. While I have no problems with companies funding research on their supplements (I like it actually!), I prefer that the researchers have no association with the studies that are conducted. In this investigation, one of the researchers has a “consulting relationship” with Isagenix.

 

My biggest question with this study is why even involve intermittent fasting? Even if intermittent fasting is part of the Isagenix program, I think a more useful study would be to take those same 54 women, do the same measurements but randomly give them either the two IsaLean Shakes or two placebo/zero-calorie shakes a day for 8 weeks, tell them to cut their calories and see who lost the most weight and was the healthiest?

 For those who are not aware of what intermittent fasting is, you can learn more about it by reading The Fast Diet which I linked to on Amazon for those who want to learn more.

Another option could be to compare the weight loss and health benefits of the IsaLean Shake to other meal popular replacement shakes such as:

Heck, they could have even compared the IsaLean Shake to Slimfast!

 

Study #2. The other study I located was titled Intermittent fasting combined with calorie  restriction is effective for weight loss and cardio-protection in obese women. This study was published in Nutrition Journal.

 

Here’s the thing. This is the SAME study as study #1. As such, it suffers from the same drawbacks that I’ve already covered. Why did they re-purpose the same study data under a different name?

 

Bottom line: Whether it’s kosher or not in the scientific community to do re-purpose the same data under a different name is irrelevant in my opinion. It’s sneaky science and it gives Isagenix distributors a false sense of how much research supports the products they sell.

While I can commend Isagenix for commissioning research on their shake, I believe this study (or two studies, if you want to think of it that way) could have been done better. My tips for a better study would include:

  •  No affiliation – at all – between the researchers and Isagenix.
  •  Compare the IsaLean Shake to just cut calories (no fasting).
  •  Compare the IsaLean Shake to other meal replacement shakes.

 

For a more in depth review of the IsaLean Shake study, see the review at Science-Based Medicine.

 

IsaLean Shake and Exercise

The Isagenix website notes that the IsaLean shake is designed to “take your health and performance to new levels.” By “performance” I assume they are referring to exercise performance. While I don’t think the IsaLean Shake will hurt the ability to exercise, I am also not aware of any published peer-reviewed research to show it improves exercise ability either. It might or might not. There is no good proof either way.

It would be interesting to compare the IsaLean Shake to anther brand, such as the Herbalife Formula 1 shake, to see which might make people bigger, stronger, faster, or healthier.  Unfortunately, I don’t think we will see that kind of research anytime soon. Supplement companies―for whatever reason―usually don’t sponsor research that takes on the competition.

That’s too bad, because that’s the kind of research we all want to see.

 

The Isagenix Cleanse

Included in the Isagenix program are cleanse days on which people eat fewer calories in conjunction with taking various Isagenix supplements. This is said to rid the body of toxins, which, after they are lost, makes it easier to burn fat and lose weight. But what are these toxins? As far as I can tell, Isagenix has no published peer-reviewed evidence of toxins being released during the cleansing process.

When people eat fewer calories (or carbs) they tend to lose a lot of water from the breakdown of glycogen (the carbs that are stored in the body). Some people may notice that they go to the bathroom a few extra times during the day when they cleanse. This is likely the water that is being released. Hopefully Isagenix will sponsor research to uncover what toxins are actually released from the cleansing days.

I welcome the insights of Isagenix distributors who would like to shed light on what toxins are actually released with the cleanse.

The Isagenix Company

Isagenix―also called Isagenix International LLC―was founded by Dr. John Anderson and Jim and Kathy Coover in 2002. Dr. John Anderson is called the “Master Formulator” of several Isagenix supplements but I can’t find what his degree is in. Even the Isagenix website doesn’t appear to give this education information.

According to the website, the company is located at 2225 S. Price Road, Chandler, Arizona 85286. That address doesn’t come up on Google maps, but I did locate another address for “Isagenix International.” That address is 601 S 54th St, Chandler, AZ and on Google maps, does indeed show a building that says “Isagenix” on the outside. That’s good.

Isagenix has a contact number of: 480-889-5747. According to the Better Business Bureau file on Isagenix, the company also has a contact number of 480-889-5777.

The majority of Isagenix supplements are sold via MLM distributors. There is nothing inherently wrong with MLM, but for those who don’t want to buy Isagenix supplements from a distributor personally, I found the Isalean Shake on Amazon as well as even the 30 Day Cleansing and Fat Burning System too.

Isagenix distributors might claim the products purchased online are not the “official” supplements, but I see no good proof of this.

For those reading this who are considering becoming an Isagenix distributor, the only words of wisdom I would offer would be:

    1.  Try the program first to see how you like it.

    2.  Find out how much the AVERAGE distributor makes per month. This is a more realistic idea of how much most people make rather than the stories of the super successful salespeople.

 

Isagenix Side Effects

I Googled “Isagenix IsaLean Shake side effects” and did not see much in the way of people saying bad things about it, but I must also say that most of the search results I saw appear to be dominated by pro-Isagenix websites. Looking at the ingredients, I think if you are healthy, then the IsaLean Shake is probably safe. For those who have health problems, show the ingredients to your doctor or pharmacist, just to be safe.

 

Does the IsaLean Shake Work?

First let me say that there are a few things I like about the Isagenix IsaLean Shake. First, I like that it has 240 calories. While this is a bit more calories than in other shakes—like Shakeology—I think this is probably closer to what people typically eat for a snack. I also like that the IsaLean Shake has more fiber. In addition, I like that the shake has 24g of protein, which when combined with the fiber, might help people feel full longer, reducing overeating setbacks. While not proven, the added protein might also help spare muscle loss during dieting.

The big question, however, is this: Is the Isagenix IsaLean Shake best for weight loss? Currently, I see no compelling proof that it’s better than other commercial shakes. While I feel it can be a healthy addition to the diet, I see no benefits―other than convenience―that it’s healthier than the homemade shake I make in my kitchen. I think this is an important point to remember for those who are price-sensitive, because the shakes can be expensive. The Isagenix weight loss study, while interesting, has some problems and if I can be candid, I could have done a better study myself. That said, I do believe that if people follow the Isagenix program, they will lose weight. But that’s not because of anything unique in the IsaLean Shake or the cleanse system. I believe people lose weight with Isagenix because they eat fewer calories.

Here is the IsaLean Shake on Amazon for those who are interested and want to read the comments from others who have tried it.

What do you think?

    That’s for this review Joe! I appreciate your feedback. I am a user of Isagenix and have released almost 30 pounds on the weight loss system. I would appreciate you taking a look at the e+ shot, Cleanse for Life and IsaDelights products.

    • Joe says

      Slraya, you are very welcome! I just added those products to my list of supplements to review (I really do have a list!) and will try to get to them. I’m glad Isagenix has helped you lose 30 pounds. My congratulations on doing that!

  2. Teresa R says

    Hi Joe! Interesting article on Isagenix. I’m an RN and currently use Isagenix. I was introduced to the product by another friend of mine who is also an RN. She simply posted pics of her progress and changes in how she was feeling. She has suffered from chronic fatigue and chronic pain for several years and had required medication for both to function in her life as a busy mom/wife/etc. There was zero pressure to join–she simply shared her results.

    Isagenix is food. Supplements are available for those who choose to purchase them. I buy some, and don’t buy others. Because I am a skeptic, I read all the labels of all the products I was interested in using prior to my first purchase. I was impressed that the protein is sourced from New Zealand cows, which are pastured, and hormone and antibiotic free. In addition it is processed under low heat conditions and is undenatured. All good. Sourcing for other ingredients is also good.

    A typical Isa day for most is two shakes, 2 real food snacks, and a healthy 400-600 calorie real food dinner. Cleansing can take place in several different ways, but the most frequently recommended is intermittent fasting. In fact, regarding the study that you cited, the author makes clear that she was actually studying the effect of intermittent fasting–not specifically Isagenix. The other participants were to eat a “heart-healthy” diet. I don’t know why she limited the trial to women only. Perhaps Isagenix was chosen due to its nutritional profile (lack of artificial sweetners, non-GMO, non-soy) and the fact that IF is already part of the Isagenix program.

    You might find part of the answer in her own words after the studies completion. I found it interesting to note that she tried the products first before she tried them on study participants. And, I personally laughed when I reached the end of the article! isagenixhealth.net/study-finds-isagenix-superior-to-leading-heart-healthy-diet/

    You also mentioned MLM. Until now, I have simply purchased products for my own use, however, I now have friends asking me about what I’m doing. The reason? Lost inches, improved mood, improved sleep. Just as I was introduced to the product by a friend, she was also introduced to the product by a friend named Tracie. Tracie didn’t intend to do anything more than improve her own health–she’s the busy mom of SEVEN. That said, her health changed and people started asking her “how and why” and now she’s earning almost as much as my husband does at his job! Oh, and she just started using Isagenix last July!

    Here’s her story: isafyi.com/adoption-counselor-and-busy-mom-has-it-all-with-isagenix/

    She’s not alone in her results. Here’s pics of another of her friends that started around the same time: facebook.com/photo.php?fbid=10152246771122728

    I could FILL your page with results like these!

    Many people are benefiting from improved nutrition. Many, like the friend who introduced me to Isagenix, no longer need their medications because of their improved nutrition from FOOD. (Isagenix is FOOD, not medicine!) Many CrossFit athletes talk about improved recovery times and increased PRs. All I know is that I am losing inches, resting well, and am the HAPPIEST I have been in years. I hope you consider trying some/all of the products you research, and like you, I would love to see a side-by-side comparison STUDY of Isagenix with similar products.

    • Joe says

      Hi Teresa, really glad Isagenix is helping you and others. when I wrote my review I wanted to focus only on the research and after reviewing the research on the IsaLean shake I did say I would not be surprised if people said they would lose weight. So, Im not suprised by the testimonials you have provided. Isagenix provides a way for people to eat less calories. There isnt anything wrong with that and for those who have been successful with it I am happy. There are many avenues to weight loss. Isagenix can be one of those ways.

      With respect to Isagenix being food, I’d point out that not everything in the IsaLean shake is technically “food” ( in other words, macro-nutrient). For example, strictly speaking enzymes are not food but I agree that when digested that they are a source of protein, which is a food (macro-nutrient).

      With respect to the intermittent fasting study, yes, intermittent fasting is part of the isagenix program however Isagenix supplements are not needed to do intermittent fasting. Also since one of authors had a consulting relationship with Isagenix, it would have been better to not use Isagenix shakes if the primary purpose was to study intermittent fasting. It just weakens the gravity of the study in my view.

      I have a couple of other Isagenix supplements on my list to review and hope to get to them in the not too distant future.

  3. cheryl greene says

    Thank you. I found your research helpful. I have been searching the web for information on this product..there seems to be a lot of hype about this product. I’ve been told by a chiropractor to take two shakes a day to help with muscle repair….. I am a skeptic. I use another product line for supplements, that I am really happy with.

    I have found that shortly after drinking the shake my jaw is clenched, like I have had a lot of caffeine. But no shaking or any other effect. Not sure I like the product.

    I am not taking it for weight loss.. so I feel a bit scammed by this person.

    I am thinking I will return my unopened boxes

    • Joe says

      Cheryl I’m glad I was able to help. I’ve never heard of a clenched jaw after using the shake. What did your chiropractor say about that? While the IsaLean shake had some attributes I liked seeing, if your other supplement is similar, just stick with that because in the end its just a meal replacement shake. You could even make something similar yourself if you liked. For what its worth, I think your muscle will be repaired just fine if you eat normally also.

      Please consider sharing my review with your friends as I’m sure its hard to find me amongst all the other reviews out there.

  4. Suzanne says

    Hi Joe, I’m sure you get plenty of requests to evaluate products but it was me at AAAI in Atlantic City this past June, where I brought up the Isagenix products. My thanks so much for reviewing and so much great information. You are the best. See you in June again!

  5. Kate says

    Joe; thanks for your due diligence, and I will just chime in and say it’s very hard to find the ingredients in Isagenix products on the web; at least a list of ingredients that aren’t supplied by Isagenix. I like to use Mayo Clinics website for health care questions on deceases, nutritional supplements and trend diets, but you have to enter in the name of the ingredient your are researching to do their search. I appreciate your report in this area in particular.

    Friends of ours have lost significant weight on Isagenix products, and have invited myself and my husband to attend a “Just Cleanse” gathering to present Isagenix. Mind you, both of these friends were thin to begin with, but they must have felt they wanted to be healthier.

    I don’t know their genetic risk to cancer, heart decease, diabetes etc, but our male friend “Jake” had a heart attack 3 weeks after he started the Isagenix shake/cleansing program that his wife “Carol” had been on for over a month prior to starting Jake on the same program.

    After talking to Carol about Jake’s heart attack, she said he complained to her about feeling tremendous pain in his mouth and jaw for several days. When he felt this pain, he would take a baby aspirin, the baby aspirin was not working and he had his heart attack within 24hrs of his last complaint of the jaw pain.

    I noticed in your “Reply” section, one of your readers also complained of jaw pain. Perhaps this is a side effect of Isagenix products, perhaps not. I do know that Jake’s medical doctor wants them both to stop using Isagenix products immediately, and wants Jake to gain back 20lbs through food.

    The Isagenix line of products is very trendy in our area right now, and seems to be given support by chiropractors (DC’s in particular). I also have noticed The Isagenix business model appears to be set up as a pseudo multi level networking business, similar to Amway and Shaklee.

    I will not be using any of these products, and will hope this as with other trend diets and networking businesses introduced will play out without any casualties.

    Thank you for your report Joe.

    • Joe says

      Kate, you are very welcome and I’m glad you were able to find me on the web (‘Im sure its hard these days with millions of websites out there!). Jaw pain is one of the signs of a heart attack. Interestingly its usually listed as a sign thats more common in women but as you pointed out, men can have jaw pain as well.

      Ultimately its difficult to say whether Isagenix was linked to “Jakes” heart attack or not. They have so many products and this could also be an unfortunate coincidence. While we may never know, I can agree with Jakes doctor and recommend he get healthy without Isagenix supplements -or any other for that matter.

  6. Sunnydae says

    Thank you for this review. It’s a very fair review. I started using Isagenix 34 days ago..I was skeptical, because like so many other products that I have tried, I failed to maintain. In all the products I’ve tried, nothing made me feel like this. I didn’t lose a lot of weight (only 4 lbs) because I still ate brownies and cookies about 2x a week. I did lose over 12 inches on my ribcage, abdominals and hip area! These are the problem areas that don’t get touched in the other diets I have been on.

    I have tons of energy and it just stirs something inside of you that makes you want to run or do a few crunches everyday. I still don’t push the products on people, if they’re interested, I tell them what it has done for me. It’s a bonus for me that I will get a little rebate to use on my own future purchases. Rebates or commission are that huge…about $25 if, that’s a big IF, a person buys a $300 system or pak. If the person buys something that is not a system or a pak, you even get lesser than that or none at all (if it’s per item purchase).

    • Joe says

      Sunnydae, you are very welcome and dont worry about losing only 4 pounds. that’s about 1 pound a week and is well within what is considered healthy weight loss. Be glad of that :)

  7. Jen says

    Thank you for your review of this product. I have been researching many meal replacement shakes, most recently Dr. Sara’s Hormone Balancing Shake. Have you ever heard of this doctor and her protein shakes and supplements? She is the NYT bestselling author of The Hormone Cure, which is a very interesting book and recently she added her own shake/supplement product line to the market.

    I have been trying to compare her ingredient list to that of Isalean Shakes to see if one is better than the other. One noticeable difference is the sugar content being higher in Isagenix, and that The Balancing Hormone shake sources protein (22g) from vegetables instead of Whey. (namely Pea, Chlorella and Potato).

    Thirdly, Isagenix also contains soy. Anyway, my research is still ongoing, not sure which product on the market is the best for meal replacement/weight loss and has the least amount of ‘bad stuff’ in it for me. Any thoughts you had would be much appreciated. Thank you.

    • Joe says

      Jen, Ive never heard of Dr Sarah’s hormone balancing shake but I will add it to my list of things to look at. Id say the best way to know if her shake balances hormones is to get your hormones tested first by your doctor and try the shake for a month and then retest the hormones again. In the absence of actually feeling better, that is the only way to really know if its altering hormone levels or not.

      Im glad I was able to help some. let me know if you turn up anything on the hormone shake or if, if you try it, how it worked out for you.

      • Jen says

        Thanks Joe. I have had my hormones tested and they were all in the normal ranges. I am curious about her shake in direct comparison to Isagenix. Namely, the difference in sugar content and protein source. I have been reading a lot of negative posts of Isagenix online and on meal replacement shakes in general. I have been making my own shakes using berries and hemp protein and almond milk but i’m wondering if i’m missing out on some essential nutrients – minerals and vitamins etc…and i’m wondering what is the best source for protein. Thanks for your time.

        • Joe says

          Jen, one thing I wonder about when I see negative – or positive reviews – is who is making the claims. What is the background of the person making the claims? Are they slamming one thing to promote another thing? While I didnt see anything “terrible” when I looked at the isagenix shake, I personally like what you are doing with the berries. Why dont you toss in some spinach or kale tomorrow and see how that tastes? Remember more vitamins/minerals aren’t necessarily “better.” Do you take a multivitamin? if yes Id say you are probalby doing ok. Generally, you cant go wrong making your shakes with food.

  8. shirlee says

    So glad that I found your website. I have had such a hard time finding actual reviews of weight loss products that are not actually reviews at the company’s website.

  9. domenic says

    Hi Joe, The Isa lean shake also contains fructose in it. I have read another review by Dani Stout who also listed a number of other ingredients that she labelled as “toxic” or “unhealthy” such as the type of soy used, potassium sorbate and a few others. Doctor Robert Lustig an expert in Childhood Obesity and the author of “The Bitter Truth” also labels fructose as toxic because it metabolizes straight into the liver. What is your opinion or knowledge on this?

      Dominic, I think we should make the distinction between fructose – which is found in fruits and high frutose corn syrup – which is synthetic. Fructose is processed differently than other sugars and as such can raise triglyceride levels in large amounts. But fruit only has a little fructose and also contains fiber which reduces us from getting a fructose surge quickly.

      Im not sure how much fructose is in the IsaLean shake (let me know if you do) but I did notice it has 8 grams of fiber so I wonder if that might help slow the entrance of fructose into the blood stream?

      The research on high fructose corn syrup – which is usually about 55% fructose and 45% glucose – is somewhat murky I think. Ive seen studies showing its bad and others showing its not bad (in “moderation”). My gut instinct on it though is that it does make my “spidey sense” tingle if we use a lot of it (and it is in a LOT of processed foods).

    If you follow the system your caloric intake is about 1200 calories. Weight will be lost. With that being said I use the system but don’t follow it exactly because the caloric intake is too low but I do feel like I have more energy when following the system by having 2 shakes a day, ionix supreme, etc.

    From what you and others have said, it certainly seems like Isagenix is largely dependent upon milk products. It seems counter-productive to general health to eliminate from one’s diet two meals per day that could otherwise have been from whole essential foods – berries, bananas, spinach, kale, eggs, etc. As you said, if one ate two low caloric shakes of any manufacturer in lieu of meals, then had a modest dinner, one would lose weight; but along the way, one would also be losing out on the great variety of nutrients supplied by real food.

    Isomaltooligosaccharide is a prebiotic which means that it is also a source of fiber. Prebiotics pass undigested and then ferment in the colon creating a healthy environment for good bacteria.
