The Truth About Isagenix

The Isagenix diet works predominantly because it's a mixture of shake days and cleanse days, meaning it has the same effect as combining portion control, caloric restriction, and intermittent fasting all over the course of one month. On shake days, you replace two meals with Isagenix shakes while the third meal should be 400 to 600 calories total. 

On cleanse days, you have four servings of the Isagenix Cleanse for Life liquid and no more than six Isagenix snacks in place of all meals. Isagenix supplements are also allowed during either day, if you're feeling particularly hungry. Once you've completed the 30 days, you can either restart it or try a different Isagenix program (there are several available). It's worth noting none of Isagenix's weight-loss claims have been verified by the United States Food and Drug Administration (FDA).
