Devotchka, I so wish I HAD this problem !!!!! With all that Diahorreah, you might be losing too many nutrients. Get some goodies back in - potassium, magnesium, zinc, vit D, omega 3, maybe some B's ???? if your body doesn't need it - it will urinate the excess, I think.
Add some good oils, cream, butter, coconut cream into your food, but don't expect too much too soon. Just like it takes ages to take weight off, it must also apply to putting it on.
