If you are (mostly) already doing this or looking for a "jump start" you can also do a liquid cleanse of pureed organic vegetables, a little fruit, and vegetarian sources of protein which will relax the body (because liquids don't require engaging the digestive process as much the body can get to some of its deeper cleaning at this time).
Some nutrients can be added in the form of teas and powders to aid the body in both phases of detoxification for a more effective cleanse (note: elimination is critical during a cleanse to make sure that you are passing out of the body the toxins being liberated from the cells…and elimination can come from all forms so body odor, bad breath, breakouts are all to be anticipated and actually are signs of an effective cleanse as long as they clear up).
A cleanse is different than a fast. And the body knows the difference. During a fast the body slows the system and its workload/efforts to compensate for a perceived lack of nutrients. To this end, if your cleanse doesn't supply sufficient nutrients (the range of nutrients -- carb, pro, healthy fats) it's likely that the body may alter its metabolic functions in a way that prevents sustainable results and may compromise short term energy and immune function.
