What Is Isagenix 30 Day System?

Isagenix 30 Day System is a weight loss program created by a US-based multi-level marketing company named Isagenix Worldwide LLC.

One 30-day weight loss system costs $378.50, contains 7 different weight loss products (in multiple quantities) and will last users for, yep you guessed it, 30 days based on the official Isagenix schedule; it is available from the official Isagenix 30 Day System website and Amazon.

When you order the weight loss system, you’ll be receiving the following products:

  • 4 x IsaLean Shakes (a meal replacement shake)
  • 1 x Ionix Supreme (an adaptogens drink)
  • 2 x Cleanse for Life (an anti-oxidant drink)
  • 1 x Isagenix Snacks (a flavored chewable that’s designed to temporarily satisfy your sugar cravings)
  • 1 x Natural Accelerator (a fat burner pill)
  • 4 x Hydrate (an electrolyte drink that’s designed to help you retain water)
  • 1 x IsaFlush (a laxative-free formula that’s designed to prevent constipation)

Note: the above is for the regular 30-day system, there is also a “30-day Premium Pak” ($585.29) that basically contains the same products with the addition of extra foods like “Whey Thins” and the “IsaLean Bars”. The contents of each bundle can also be slightly different depending on which country you live in.

Isagenix have targeted this product towards those who are looking for a “foolproof” method of weight loss. The system provides users with direct instructions to follow, which can help to ensure results provided that they’re followed correctly.

The Isagenix 30 Day System Schedule

Rather than just dropping you off a bunch of weight loss supplements and leaving you to it, Isagenix have put together a schedule that you’ll be following. The schedule involves “shake days” and “cleanse days”.

Shake days are on days 1-2, 5-9, and 12-30, while cleanse days fall on days 3, 4, 10 and 11. Isagenix also provide a rudimentary exercise routine that you need to follow each day too.

As the name suggests, shake days involve replacing your 3 daily meals with the provided IsaLean Shakes (though they give you the option to eat a regular 500-calorie meal for your dinner instead of a shake, if you’d like); the shake day is essentially putting you onto a low carbohydrate VLCD.

The cleanse day is a little more interesting. As you’d expect from the name, this is the day you’ll be using the cleanse for life drink and the flush supplement, but you’ll also be abstaining from food (other than the allocated “Isagenix Snacks”); it is basically a fast day where you don’t eat.

Does Isagenix Work?

After looking closely at the schedule and products provided inside the bundle, we believe that if you’ve got the willpower to follow it, then you should have no problems seeing weight loss results at all; based on the set directions in the schedule, you’ll only be consuming around 700-1100 calories per day.

As we mentioned above, the Isagenix diet plan is basically what’s known as a very low calorie diet (VLCD), with nutritional sources provided from Isagenix products, rather than foods you could prepare yourself. The truth is, Isagenix haven’t created something revolutionary with their diet plan, they’ve essentially just packaged together an easy and convenient way of sticking to such a diet (though they’ve also thrown in some diet pills, antioxidant drinks and colon cleanse pills into their 30-day bundle too, which obviously wouldn’t be included in a normal VLCD).

So we’ve established that it will very likely help you lose weight if you follow the directions, but we should discuss the main drawback (this drawback is applicable to most intense caloric-deficit diets) – you’re going to need willpower by the bucketload!

That’s right, drinking three small shakes per day for 26 days, and not eating anything for 4 days is going to be tough. If you’ve been used to consuming vast amounts of calories each day, or if you’ve had a carb-heavy diet, you’re probably going to feel extremely lethargic and fatigued.

The bottom line: The Isagenix 30-day weight loss system isn’t really bringing anything new to the table in terms of diets, but it’s carb-minimal, will crash your daily caloric intake to the point where weight loss is almost guaranteed, and involves 4 days of fasting (i.e. 4 days where you’ll not be eating a thing). You’re going to need a massive amount of willpower and determination, but if you can persevere, you’ll reap the rewards.

The Pros & Cons Of Isagenix 30 Day System

Below we have listed everything that we like and dislike:

The Pros

  • Puts users onto a low calorie diet that will ensure weight loss.
  • Contains useful products to help prevent the negative side effects that a VLCD (very low calorie diet) can cause.

The Cons

  • It’s a very expensive plan to follow.
  • The 30 Day System contains products that we believe are unnecessary and only serve to inflate the price.
  • The diet plan doesn’t teach consumers proper nutrition in our opinion .
  • Will require vast amounts of willpower.

What Are The Isagenix Side Effects?

Based on the fundamentals of the Isagenix diet, the side effects could be:

  • Dry mouth
  • Constipation
  • Fatigue
  • Diarrhea
  • Headache
  • Dizziness
  • Cramps [1]

Note: these side effects are possible but may not be the typical user experience.

Is The Isagenix 30 Day System Safe?

We believe that the diet is absolutely safe as long as you do not sustain it for a long term period. You should also check in regularly with your doctor to ensure your health isn’t suffering.

These types of very low calorie diets should only be sustained for a maximum of 12 weeks according to the United Kingdom’s National Health Service.

These diets should only be followed under medical supervision for a maximum of 12 weeks continuously, or intermittently with a low-calorie diet – for example, for two to four days a week. –

Are There Any Isagenix 30 Day System Reviews From Customers?

We have found the following Isagenix 30 Day System review testimonials via customers on Amazon:

This is a great product for people on the go. Keep metabolism going with quick & easy shakes for breakfast and lunch, enjoy a healthy dinner. I’ve lost 14 lbs and 17 1/2 inches, and I’m only a little more than halfway through my 30 day program . Very satisfied, will purchase again, but most likely through an actual isagenix seller so I can buy it cheaper.

Waste of money. People can lose more by eating healthy and exercising more. Common sense if you ask me!!

Our Final Verdict On Isagenix 30 Day System

To conclude our Isagenix 30 Day System review, we like it, but it’s crazy expensive and doesn’t exactly teach the user proper nutrition – it just turns them into a customer.

It’s not a terrible way to lose weight, in fact it’s based upon a very solid VLCD concept, but you’ll absolutely need a ton of willpower to make it work. If you’re able to follow it correctly you’ll no doubt see yourself lose weight, but that would be the same if you followed a regular very low calorie diet.

When you buy the Isagenix 30 Day System, you’re essentially purchasing the schedule plus a bunch of low calorie shakes and other supplements – if you’re on a budget, we believe that the schedule could be replicated with foods you could buy from Walmart.
