Well contrary to what the others have said I would say it is definitely not normal. if it goes on much longer you will be get constipated and then the paid will kick in. I would suggest doing a "clear out" wiht Dulcolax or Senokot and then take Fibresure capsules. You can get them in the chemist in the vitamins section. It says on the packet to take 2 x 3 times a day but I take 3 x 2 times a day. And I also try to take it at a time when I'm having shake etc. It definitely hasn't effected ketosis and I think the losses speak for themselves.
Happy pooing! And best of luck on your journey.
