You may be asking yourself, “will I be hungry during a cleanse?” Luckily, the answer is no. Kathy states that the Nutritional Cleansing program feeds the body hundreds of nutrients, organic minerals, and several other ingredients that nourish the body while cleansing it so that hunger urges are avoided during the process. Kathy also says that the hardest challenge during a cleanse for product-users is being surrounded by food. As a helpful tip, she recommends that you conduct a Nutritional Cleanse on a day that you won’t be grocery shopping or cooking a dinner for your family so that you can effectively avoid unnecessary food cravings.
People who are involved in the nutrition field are far more knowledgeable, they have vast amounts of education on this subject, and a huge advantage over let’s say a car mechanic when it comes to figuring out the good from the bad at the local grocery store (which is where the majority of Americans shop for their food) Label reading is extremely hard, especially if you do not know all the bad things to look for as a trained professional would know like the back of their hand, such as yourself. A great portion of Americans know the simple pit falls in eating, like, do not eat at McDonalds, don’t eat donuts for breakfast lunch and dinner. I am not saying it is the total education of the individual, but nutritional education which not that many people have, is key here.
The Isagenix cleanse is unique because it not only removes impurities at the cellular level, it builds the body up with incredible nutrition. Besides detoxing the body, Isagenix teaches people a wonderful lesson that they don’t need to eat as much as they are accustom to and eating healthy choices are really important and also a lot of the food we are eating is nutritionally bankrupt.

Castoreum is a chemical compound that mostly comes from a beaver’s castor sacs, which are located between the pelvis and the base of the tail. Because of its close proximity to the anal glands, castoreum is often a combination of castor gland secretions, anal gland secretions, and urine…Still concerned you’re chowing down on beaver-bum goop? Because of its FDA label, in some cases, manufacturers don’t have to list castoreum on the ingredient list and may instead refer to it as “natural flavoring.” Yum. Source
Also, above there were some comments about the low-heat nonfat dry milk. I have a shake canister right here in front of me. It mentions that the whey protein concentrate and the milk protein concentrate are undenatured…it does not say the low-heat nonfat dry milk is undenatured. Isagenix claims it’s whey protein is undenatured. Not the low-heat nonfat dry milk contained in the shake. Just for clarification of what Isagenix is claiming.

I actually wanted to try this product, but now that I’m listening to the distributors on this blog ranting, it has actually turned me off. Thank you guys for showing me that your product is being represented by individuals who truly have no knowledge of nutrition. I would have appreciated it more if you would have shown the research that has been conducted, and perhaps had shown the wonderful wonders of this product and the great health benefits your product promotes. You didn’t. All you were able to accomplish was to turn a would-be customer off. I’m glad I didn’t purchase the product now. Very sad that you are representing the product in such an unprofessional manner.
I actually don’t get paid to write posts as I don’t accept sponsored posts. And if you actually “hire bloggers for a living” which I’m not even sure what that means, you would know that bloggers rarely, if ever (I’ve never known a blogger to get paid for this and I know a lot of bloggers) get paid to write against products. I’ve never been paid to write an article actually. The disclaimer is for my affiliation with companies like Amazon, doTERRA and Perfect Supplements.

Please enlighten me Dani on how many people you have helped with being healthier and happy with yourself. Regardless of what you say is toxic etc I couldn’t two sh*ts about that at all. But the people that you have helped acheive their fitness goals compared to Isagenix. I am not sure as to whether it is comparable. The information you have given maybe true but think about the lives that this product is changing perhaps? You call that sly, another MLM scheme and complain that they dont sure everything. WHo cares it changes lives!
The people involved in the manufacture of Isagenix products are of the highest pedigree. I won’t start listing names… I’ll leave it to you to research. The names you’ll find aren’t world class athletes.. in fact, unless you’re a scholar of nutrition or high level personal training, you’ve probably never heard of them… they’re the people that world class athletes look to.
Wow! This is great! I was approached by someone during the week – trying to get me to rep this product for them, because I “have good energy” I knew nothing of it, and assumed it was something far natural and sincere. So I sit down to find myself watching the most ridiculous video ever, of all these weird cult like people, claiming that they no longer work but make MONEY MONEY MONEY.! This is so far removed from what I think a healthy person (body and soul) should be like. It appears just another brainwashing scheme, spend money to find health and happiness. There are many more ways than this stupid company! Sure people do this and lose weight, good for them, but I agree that there are many other HEALTHIER ways to do so. You don’t need to buy packaged, manufactured crap. People need to wake up. Spend time, not money on yourself. Way to go Dani! Loved the read, and will follow your blog now too! All the best to you. 🙂

Thank you so much for this article!! I was thinking about trying Isagenix after a summer of over indulging in food and beer but I decided to do some online research first and came across this review. It’s articles like this that make me step back and say what am I doing? For me putting down the fork and beer and getting back to a routine of eating organic fruits and veggies will help me so much more than Isagenix or any other shake out there.
Raw nuts and seeds provide healthy fats and protein. Dried beans and legumes, such as lentils and chickpeas, provide protein and phytonutrients. Brown rice, quinoa, teff and millet are whole grains that you can find in the bulk bins at health-food stores and in some grocery chains. The fiber in the whole grains and produce will help keep you full and helps regulate your digestive tract.

The average detox diet and cleanse lasts for a few days or weeks, but regular cellular cleansing, and using True Cellular Detox™ periodically, is a lifestyle change. Dramatic shifts in health may not occur overnight (though it’s possible), but cleansing at the cellular level is the only way to get real and lasting results in your health.If you are a certified natural health practitioner and are interested in integrating a true cellular detox system into your practice, please call 724.292.7673.


Thank you for this article! I have been a very successful network marketer with both Beachbody and Visalus…I did help A LOT of people lose weight and “get healthy…-er” than they were. But through my OWN research and dissecting each ingredient in the products I consume as I became more interested in researching all of the supposed healthy ingredients, I have found that google does a body good! If you copy and paste the ingredients into google and ask “IS ______(insert ingredient)___ non-gmo/organic?” you will get ALL sorts of reliable info. I have YET to find an MLM that produces a truly NON-GMO and Certified Organic product. Now, some claim they do…but their ingredients say otherwise. And let’s be real…every website is going to vouch for their product. What kind of company would they be if they outed themselves? Think about it!
Still asking the Hangover Gods for forgiveness? Ask a loved one to please prepare you a side of steamed asparagus with a protein-rich lunch. According to a study in the Journal of Food Science, the amino acids and minerals found in asparagus may alleviate hangover symptoms and protect liver cells against toxins. The veggie spears are also a natural diuretic, which will help flush the excess toxins from your system. Avoiding starchy carbs will help to further relieve your body of bloat, while protein—rich in vitamin B6 and amino acids—will help to alleviate groggy hangover symptoms.

Herbalife, Isagenix… and all the rest. Those products are all terrible and marketed disingenuously, taking advantage of people’s ignorance on nutritional matters. However, this article is truly awful and just presents a different set of bad information also sourced from people profiting from people’s ignorance on nutritional matters. Mercola, specifically.

A short juice cleanse might not pose an immediate danger to most people, but going all-juice might have more subtle risks, experts warn. “This type of diet is like shock treatment to the body,” says Meredith Luce, RD, a nutrition consultant with the Rosen Medical Center in Florida. “By eating one day and fasting the next, you stimulate the body’s starvation response. When you do eat again, your body hoards calories, making long-term weight loss more difficult.” Another problem Luce notes is that dietary cleanses don’t instill healthy eating habits. "Cleanses of this type allow people to justify bad behavior,” she says. “In other words, ‘I’ll eat and drink whatever I want this week, because I’m doing a cleanse next week.’ Cleanses promote the mentality of a quick fix as opposed to long-term balance.”


To do so, Larson suggests making one change in your diet per week. For example, you can try to add an extra fruit or veggie to your lunches, aim to get more protein-rich meat alternatives in your dinners, or pledge to really, definitely, for sure eat a nutritious, energizing breakfast every day. You could also aim to bring your lunch from home a few more days a week.
If Isagenix products were so unhealthy you wouldn’t have people lowering their cholesterol, lowering diabetes medications, coming off blood pressure, antidepressants etc etc Obviously all in consultation with their doctors, who are amazed at how healthy they are and what great work isagenix did in their body, allowing the body to heal itself, cleansing out the toxins. Speaking of toxins, the isagenix system is designed to do just that. A good video showing this at the blood level by Jim Rhoades is http://www.youtube.com/watch?v=BesUttqdy2w
Okay, so you won’t be dining at Waffle House this week. To make the cleanse work for you, you’ll need to make your own dinners for the next seven days, or special order off the menu of your favorite restaurant. Cleanse Dinners consist of protein and vegetables, and healthy fats, but no grains or fruits. A little harsh, but again, it’s only temporary. Metabolism decreases up to 35% during sleep, so any extra carbs in your system at bedtime are more likely to get stored as fat. Grains and fruit are the main carb sources in our diets, so I’m stripping them out at dinnertime for the next seven days.
You may be tempted to reach for the meds, but medicating with vitamins from whole foods—blueberries in particular—is a much better, all-natural option to perk-up a compromised immune system. In fact, you can think of each sweet little blueberry as a pill that’ll make you feel a whole lot better. Oregon State University recently took a look at over 400 compounds for their ability to boost the immune system, and the study revealed blueberries as a standout due to a compound called pterostilbene. Goodbye Pepto Bismol, hello Pterostilbene! Bored with plain blueberries? Try any of our 50 Best Snacks for Weight Loss for nourishing eats that are also delicious.
An Isagenix-funded study published in Nutrition & Metabolism in 2012 found that over an eight-week period, people who used Isagenix meal-replacement shakes as part of an intermittent fasting and calorie-restriction diet lost 2.2 pounds more than those who followed a similar diet using regular food. However, according to a 2012 article published on the Science-Based Medicine website, this study wasn't well-designed, and Isagenix paid to get it published in the journal. The author of the website article, Dr. Harriet Hall, also noted that there were inconsistencies in the numbers listed in the results, potentially making the conclusions unreliable. 

I doubt you were with Isagenix for 13 years it took you that long to figure out it was a scam? Lol sounds a little weird to me, I can vouch for this product it does work they are great products and yes we are making money and know others that are also making a lot more, obviously your not very informed about this company or you just failed miserably and is just bitter.
I don’t use either or ANY of the products you’ve done reviews on. I’m with you, TOTALLY, about eating WHOLE, REAL food FROM THE EARTH! I cannot stress that part enough – FROM THE EARTH! That is what our bodies were made to absorb. Limiting good fats, limiting cholesterol (which our brain absolutely needs because it’s made of 100% cholesterol), not eating the WHOLE EGG, drinking skim milk or even “organic” milk….it’s STILL pasteurized, ultra-pasteurized and homogenized, which equals NOT REAL or ORGANIC, can def be detrimental. If it’s not “raw” or “whole” or not tampered with, then it’s NOT REAL, right?

Thousands of natural volatile compounds make up the flavors and aromas of the things we eat. Even simple natural flavors like vanilla can be made up of hundreds of compounds, most of which have very strange sounding chemical names. For example, d-limonene is one of many natural volatile compounds that make citrus taste like citrus (2), and 3-methylbutanal, 3-methyl-l-butanol, and geranial are compounds that help make tomato taste like tomato (3). Listing all of these natural flavor compounds as their official names on a label would not only lead to more confusion, but also look a little scary… (see Nutritional label of banana which I posted in response to another post down the page a ways)
Re: fructose – 50 grams is very high. Not to mention PaleoLeap says “for healthy people.” Most people who resort to Isagenix aren’t the healthiest and do so because of health and weight problems. I eat less than 10 grams of fructose per day. Dr. Mercola recommends under 25 (http://articles.mercola.com/sites/articles/archive/2011/02/28/new-study-confirms-fructose-affects-your-brain-very-differently-than-glucose.aspx and http://articles.mercola.com/sites/articles/archive/2011/05/02/is-sugar-toxic.aspx)
I agree that all natural is the best way to go. Recently came across the Wahl’s Protocol reinforcing my belief. Have also reviewed studies and TV clips, including 60 Minutes coverage, about how any type of sugar is in fact toxic and increases the bad kind of LDL is our bloodstreams leading to more heart disease. Any company making money by selling a weight loss diet to and because we are a mostly uneducated public, while not illegal, is borderline unethical and most likely quite profitable at least for those who own the company or are high up in the ranks. The list of product ingredients provided above looks to be low quality/least cost similar to highly processed food items. This may lead to an increasing likelihood of negative health side effects as time goes on.
Saying that all vegetable oils are “inflammatory” is nonsense. It’s true that omega three fatty acids alter the pathway of eicosanoid production towards less inflammatory forms, and they can be very useful for people in states of chronic inflammation (RA, obesity). But n-6 fatty acids are also an important part of human nutrition. Inflammation is a normal and healthy response to injury and disease, you’re using the word as if it’s an unnatural, evil phenomenon.
You mentioned many times in your blog and in responses to others that your objections were only to certain products, ingredients, or processes from Isagenix. I have been using it for about 6 months now. I do not sell or promote it and am not a fanatic or nut like some of the others posting here have been portrayed. I initially started as a serious skeptic, talked reluctantly into it by my wife and sister-in-law. I had a serious weight problem and my health was gradually getting worse. While I may or may not agree that certain Isagenix products are bad or good for me, I have had a significant improvement in my health and weight during this time. What I object to the most in your presentations is the blanket statement, “Isagenix is unhealthy,” while saying that it is certain products and their ingredients or processing you object to. I could find absolutely no reference to one of their flagship products, Product B, anywhere in your site and yet, it is probably the most important of all their offerings. This is probably what has helped me the most of all the Isagenix products, although I have received benefits from others as well.
I do want to say (and nowhere did you say or suggest otherwise), that I met MANY great people in Isagenix. Many were kind, caring, motivated, fun to be around, and truly wanting to live a healthy life-style. I could go on and on about how Isagenix does what it does and succeeds in the ways that it does but I don’t feel like that is right on your blog and quite frankly, would be quite an endeavor of writing – as I have given much thought to the subject having been an Isagenix Associate myself. I will say, however, in a nutshell that structure, convenience, eating better (“better”, as you clearly pointed out, doesn’t mean healthy), being told things from people representing themselves as “experts” and health professionals, seeing and reading testimonials, and feeling apart of something bigger than yourself that’s preaching health and wealth can be very powerful.
Calories in v Calories out, exercise etc etc, these are all the common sense answers to any attempt to lose weight. If you take Isagenix or any other product to SUPPLEMENT your lifestyle then you are more likely to achieve success, so if you look at Isagenix or other SUPPLEMENTS in this context then they will help. Maybe use them as a jumpstart to help you improve other lifestyle habits like the fruit and veggies and exercise. I have never tried this stuff but over the years as a Professional Athlete I have tried many, but they have never been the hook on which I hang my nutritional requirement hat….
A colleague was telling me about the product who has lost quite a bit of weight. She says she feels amazing… How could I not want to know more? But, I am cynical by nature and wanted to know more. I guess the things I was wondering were; if this product is so great, why is it only available via MLM methods? Wouldn’t it be available everywhere for everyone, rather than kept quiet? Something just didn’t add up, and I wonder if in fact the colleague is being conned? The more I look, the less I like what I see, almost like a pack mentality from the people involved?

It was as if no one had actually read what I wrote. No one bothered to address any of my specific criticisms. No one even tried to defend Isagenix's false claims that toxicity accounts for most disease, that the body protects itself from toxins by coating them with fat, and that internal organs become clogged and deteriorate if you don't cleanse. No one offered any evidence that “detoxification” improves human health. No one tried to identify any of the alleged toxins or show that they are actually removed. No one tried to provide any rationale for the particular combination of ingredients (all 242 of them!) in Isagenix products. No one questioned my assertion that “no caffeine added” is inaccurate labeling because green tea, which is added, contains caffeine. No one commented when I observed that the amount of vitamin A in these products is dangerous and goes against the recommendations of the Medical Letter. No one offered any evidence that more weight is lost by adding Isagenix to a low-calorie diet and exercise. I offered some alternative explanations that might account for people believing that Isagenix is effective when it isn't; no one commented on that.
