I have GD but find lots of protein and veggies is what fuels me and baby. I'm eating so much meat but feel better- though I eat all the time.
I haven't gained weight, actually I have lost 5 lbs in the past month but baby is growing and I am not spilling keytones. I've also been walking 20-120 minutes a day ( split up into short walks after meals)
However I eat when I am hungry. All the time. And I make sure my hunger isn't dehydration.
