I am much earlier in the journey (8 weeks) and currently still in the 'whatever works' realm of slight nausea. But prior to this I'd been enjoying 6 months of no grains, low sugar, high fat diet. I'd lost 5lb and more inches and I was really enjoying it. I've been thrown a bit for a loop so far as I've never been fussy and I'm all over the place right now. I spent the day yesterday eating things made from wheat flour, which I've previously happily avoided.
I've got loads of recipes I could recommend though. What do you like, how much do you want to cook. I could live vicariously through you! At the moment, the breakfast I can deal with is 1 cup (american measure) greek yogurt with one cup fruit, topped with chopped nuts and a drizzle of honey or maple syrup. If you use frozen berries it's a bit like icecream, if you used poached fruit its like those fage fruit pots.
I made these recently and they were great - chickpea flour (also called besan) is a good low GI substitute and you can freeze them. I suspect eating 4 in one setting like I did would probably negate some of the healthy.
I've been a bit 'huh?' about all the 'eat low fat' advice that seems to be aimed at eating healthily pregnancy. Studies show that sugar's more of a problem, and often 'low fat' alternatives are loaded with it.
Right now I've been trying to think of a low sugar ginger cordial solution. I am So Bored of my soft drinks options, which are pretty much sparkling water if you want to avoid sugar or sweeteners. Coconut water, sometimes.
