o Cleansing based approaches o Diet based approaches
Cleansing based approaches include a separate cleaning stage (usually fasting or severely restricted diet). In diet based approaches you eliminate unhealthy items from your diet, thus reducing the stress on your body and allow it to slowly heal itself.
People are often put-off by the cleansing based approaches because they fear that they can't go through them. Personally I think that cleansing based approaches are actually easier to go through than diet based approaches.
Why? Because it's much easier to bear few days of discomfort (hangover like) than to fight your craving for weeks if not months.More on this little bit later, but fasting and other intense cleanses actually give you a clean break from food and substance cravings. Thus you are much more likely to stay healthy after a fast because the cravings are either eliminated or significantly reduced.
WarningWhile detoxing is completely safe for most of the people there are some cases when you should proceed carefully. Pregnant or breast feeding mothers should take care when detoxing as the toxins from your body can enter the embryo or your breast milk. Also if you have diabetes or other serious degenerative illness (like cancer) please consults your doctor before beginning your detox. You should also check with your doctor if you have been on medication for a long time.
