All... I lost instead of gained .. but I believe it had to do with switching to the anti-candida diet.. my body missed all of the sugar and carbs...
I read in a few places that mold sickness causes weight gain, and since this disease has a large fungal component.. it seems to make sense.
A couple of websites:
symptoms
One symptom=Sudden weight changes (Detoxifier genotypes tend to gain weight, non-detoxifier genotypes tend to lose weight)
Mold Misery - The Symptoms - Aesthetic Issues: Odor and Skin
and many more.. just something to think about...
