Hello form somebody who has similar symptoms. I have tried to find the answer to this problem, which for me is connected with a type of CFS, low energy at times and abnormal intestinal flora. IT seems that weight gain and water retention whenerer one is starting to lose fat is connected with a problem in liver metabolism, possibly methylation. Do a search about it. There is a protocol for the so called methylation cycle block and there are some quite complicated tests to confirm methylation blockages. It surely seems difficult to cure because it is the result of a vicious circle in the liver. But the protocols, based on vitamin B12 and some other supplements, seem to be able to take one out of it. I would be happy to get connected with people having this problem and try to combine our efforts for a cure.
