The Purify Cleanse is our most extreme cleanse. The Purify Cleanse is designed for people who are health conscious and considerate of what they eat. The Purify Cleanse eliminates most carbohydrates, fruit and sugar from your diet and provides your body with approximately 1200 calories per day. Despite the low calories, the Purify Cleanse provides you with enough energy to get you through the day without feeling light headed or weak. Planning a day or days off is not necessary. You should be able to carry on with most of your normal daily activities; however, taking it easy would not hurt. We recommend that you stay on this cleanse for a minimum of three days but if you can, you should try to go for longer! Feel free to extend your program to test how long you can go.
