None of the cleanses on this web site "cure" anything. They are "cleanses" they take the junk out so the system will operate more efficiently and not be burdened by all the toxinsto allow the body to "heal itself". The actual cure happens after the cleanse in the rebuilding process of what you put back in. If you go back to your old habits and eating the same foods don't exercise etc you will go back to where you where and in the case of weightloss since fasting slows the metabolism you will not only gain the weight back real quick ,you can gain back even more than you lost because of the slowed metabolism. It is not about the quantity or portions you eat but it is about the quality, what you eat and balance. Exercise is always essential to any health regimen.
The fasting is the easy part where everything is all worked out for you and you don't hafta make any decisions. It is what comes after that will take educating yourself and focus and lots of experimentation so don't make a big deal of the cleanse and concetrate on what you are going to do after.
From experience after 7 MCs( 5 40 dayers) and having been around here on and off for 5 years sharing others experiences I will tell you that the tongue thing can vary greatly.
Bottom line is that there is not magic demarcation point as to how long you should fast. Bottom line is that you are not going to clean out a lifetimes worth of toxins in one fell swoop even with a 40 day MC. It is just a great start. It >all< hinges on what you do after.
Nutrition and exercise are the only ways to affect any real "cure". Do all the cleanses to get the junk out then rebuild with sound nutrition and exercise. There is no way around this. THERE ARE NO SHORTCUTS it's gonna be gradual and it's gonna take time proper nutrition and a lifestyle change.
Soooo keep fasting. The real cleansing at the cellular level is just about to begin for you cause it takes the body around 2 weeks to completly adapt to fasting. To me 21 days is the minimum. For me at around the 3 week mark is when the mental aspects of fasting start kicking in and it's the part I enjoy most and keeps me coming back to the long fasts.
After the 3 weeks mark it has always been a walk in the park for me. At around the 30 days mark or so I feel I kinda hit a plateau where any gains slow down. I'll ride it out to 40 just because according ot many practices it is the mark that is claimed to cement the mental changes. Sooo keep on truckin' and take it week by week and see how you feel and what circumstances allow you to do.
