I am not counting calories. I easily eat that much not pregnant.
You might want to look into the Brewer diet, especially because you've been feeling ill.
I think my baby is a precocious reader, because ze already seems to know Brewer's recommendations - the baby is demanding that I eat several small meals a day, and to load up on protein.
For me, it's been a struggle to eat enough protein, because when you're STARVING right NOW, it just takes too much time to poach a chicken breast. My strategy has been to cook a lot of protein ahead - like hard boiled eggs, having hearty soups in the fridge, making a crockpot roast and slicing it up for sandwiches, that sort of thing.
So, in a typical day, I'm eating something like this:
Smoothee in the morning: frozen fruit: 1/4 C raspberries, 1/2 C blueberries, 1/2 C strawberries, a banana, with 1/2-1 C plain kefir, and sometimes some protein powder. Sometimes milk and yogurt instead of kefir.
I also make a 16 oz travel mug of herbal tea that I take with me.
Mid-morning - about 12 oz of oatmeal I made earlier in the week, I make it with oats, raisins, cranberries, apples, sometimes dried apricots, and some cinnamon and nutmeg, and then I store it in jars in the fridge. I add about 6-8 oz of milk when I eat it, cold.
Lunch - I usually get too hungry and freak a bit, so I stuff a couple of hardboiled eggs in my face before I eat. I try for something like a beef sandwich. That seems good. I have a huge glass of milk with lunch, most days. I often have an apple as dessert, or a sliced up orange.
I aim to have drunk at least 20 oz of water by lunch.
Mid afternoon - a little piece of cheese, I just bought some string cheese for convenience, it's really easy. A boiled egg. Something like that, or a glass of milk with a brownie or a cookie or something sweet.
Later-mid-afternoon - veggies. I fill a container with raw veggies in the morning - baby carrots or carrot sticks (I know baby carrots cost like 10X more, but they are SO convenient!), celery, and a pepper in slices. My goal is to have eaten those veggies by dinner...so I snack on them throughout the day.
Before dinner, I want to have drunk another 20 oz of water.
Dinner - often not as heavy as lunch was, because I'm so tired in the evening. Last night, I had two big bowls of tom yum soup (thai soup with huge chunks of chicken and tofu in it, plus lots of lightly cooked veggies.) Lots of times, I reheat leftovers or something frozen that I made ahead. I use my crockpot A LOT. Most nights, another glass of milk with dinner.
I'm trying to eat a simple salad, mostly romaine lettuce, which I actually often just wash and munch on plain while I'm heating up dinner.
I tend to eat dinner pretty late, so it's often my last food of the day, if not, I'll have a bowl of ice cream after dinner.
And I'm trying to get another 20 oz of water after dinner...but not too close to bedtime!
I'm really struggling with exhaustion, so extra protein and more water should help with that.
