On the 2 days of fast ( which do not have to be consecutive) the dieter must consume no more than 500 calories (600 for men) total that day.
The Isagenix Diet Plan is quite similar to the Fast diet in that we also advocate 2 days of fasting in a nine day period, we refer to it as cleansing days. While we recommend the other days of the week you replace 2 of your meals with one of our Isalean shakes and a 3rd sensible meal and approved snacks, sorry no "feasting" .
If you feel like you would want to try the 5 and 2 diet but still want to use Isagenix products to make it easier and more nutritious on fast days try our Isalean shakes in Chocolate, Vanilla and Mixed Berry or one of our meal replacement bar options.
