There's little doubt that Isagenix can help its users lose weight temporarily, although there is nothing that helps people lose weight in Isagenix that is not in food that you can buy at the supermarket for a lot less. The easiest way to understand what Isagenix can really do for you is to go through this checklist of common questions and answers about the Isagenix 9-Day Deep Cleanse and Fat Burning System and the Isagenix 30-Day Cleansing and Fat-Burning System.

Q. What does Isagenix give me that I can't do for myself?
A. Isagenix gives you a plan for eating less. There are two shakes (that you make yourself) and one low-calorie meal per day. You won't suffer deficiencies of nutrients, fiber, or protein, and you don't have to do a lot of thinking about avoiding overeating. However, you could do the same thing by eating a cup of yogurt as your entire meal twice a day, or buying a much less expensive ready-made canned shake in the diet section at your supermarket.
Q. Isn't Isagenix all-natural?
A. The second-named ingredient on the label of the shake is fructose, such as that found in high-fructose corn syrup. To be fair, the product contains all the protein anyone needs and a variety of minerals and vitamins along with probiotic Lactobacillus. It is free of G Mos and its protein source is organic dairy from New Zealand. However, it is not all-natural.
Q. What about the accelerator capsules? Do they work as advertised?
A. The accelerator capsules contain green tea extract, chromium, curry cinnamon, red pepper, and alfalfa extract. There isn't a lot of evidence that these ingredients in the dosages offered in the product are very helpful for weight loss, although the company did choose the right kind of cinnamon to put in the product (the kind of cinnamon most North Americans and Europeans use in cooking does not have a blood sugar control or weight loss effect). Green tea extract is typically only effective when consumed with caffeine. Alfalfa extract can be dangerous for people who have autoimmune diseases, such as lupus.
Q. Hasn't Isagenix been subjected to clinical testing?
A. It has, in obese women aged 35 to 65, but only in conjunction with another diet method called intermittent fasting (skipping meals for up to 24 hours at a time up to twice a week). Even in this study, cited at the end of this article (it is available in full text online), women who used the product only lost one additional kilogram (2 pounds) of weight in 10 weeks.
Q. Why do some people get such good results from the plan, while others don't get any results at all?
A. The people who lose the most weight on Isagenix, at least at first, are those who tend to overeat the most. The more weight you have to lose, the more quickly you lose weight at first. If you choose to stay on the plan indefinitely, you probably will keep the weight off indefinitely. However, even a tiny slip (a large piece of birthday cake, for example), will add a couple of pounds (a kilo) of water weight or more.

For most of us, the only way to lose weight is to eat less. Isagenix Cleanse is fine if (1) you don't mind the cost and (2) you can't stick to any other diet plan. This could be the weight loss diet that works for you. There is nothing special about its ingredients, however, and anything you can do on Isagenix you could do on your own, if you can stick to a different plan.
