Some people describe unusual weight gain and some people describe unusual weight loss while others have no weight issues at all. I don't really understand why though I remember reading about intestinal bacteria and weight problems. According to the article, if you have a lot of a certain bacteria, your body will be extremely efficient at processing food and you will have (perhaps too much) weight loss. Too much of a different bacteria could mean too much weight gain.
Considering a yeast problem goes hand-in-hand with intestinal imbalance, this could be at least part of the reason of the seeming contradiction of some people having weight gain and others have loss while suffering from yeast troubles.
From what I've seen and heard, it seems like unusual weight gain is more likely than loss. I used to have a gut which would never go away no matter how hard I tried. I started the anti-yeast treatment and the gut disappeared very quickly. Perhaps this was candida related bloating since it disappeared so quickly.
