I just try to eat a good amount of protein with a small amount of carbs so for example here's what a day might look like for me
Breakfast-eggs,ham and toast
Lunch-sand which but only one piece of bread, some vegetables
Dinner-main protein (steak, chicken...just protein) green vegetable and a small starch, either a roll or very small amount of potatoes
I drink water and maybe a very small amount of milk, it's important to snack too to keep your sugars stable, in the beginning, I was having problems with my numbers actually being too low, I try to eat every hour and a half but it doesn't have to be something big, I was worried about weight gain at first but I have yet to gain anything in this pregnancy and I have actually continued to lose a little bit...
