So sorry to hear of your miscarriages,
have a few friends dealing with this, it can be so stressful.
I'm sure it doesn't make it easy on your body also.
As far as maintaining I realized I am very carb sensitive, I've been following
the Paleo lifestyle and its been working great. I do only have one to two peices of fruit a day or I see an increase slightly on the scale,
I know its crazy, but it comes down to being carbs(sugar), natural or not, ugh! Probably causing inflammation more than fat.
And I love my fruit too.
One day at a time, hang in there! You'll figure out what will work for you.
