You don’t have to do the cleanse if you don’t want to, I didn’t do it but still recovered…
Have you checked out the forum’s cleanse?
To keep your weight up, you should eat the teff/coconut bread found on the recipe part of the forum (look for the coconut bread recipe). I also highly recommend the pumpkin pie muffin bread. Also, coconut milk has like 75% saturated fat, so if you drank this up, it could help as well.
In general, you will lose weight with the diet but in time it will all come back.
