A cleanse is not a good weight loss tool, and it's not for everyone. Consider these points before you start.
1) Set Goals. You don't need a cleanse to feel healthy, but it is an opportunity to give your digestive system a mini-break, jump start healthful eating, re-check portions and eliminate possible allergens.
2) Avoid: artificial sweeteners, dairy, gluten, soy, alcohol and most caffeine. Red meat should go, and make sure any protein consumed is organic.
