In case this helps anyone else...
Because I couldn't consume the quantities I could before I got pregnant fue to my weird hormonal appetite, my sponsor immediately worked out adding a bit of fat and fruit to my diet (since fruit was one of the only foods that I can stomach most of the time).We decided to split my meals into 4 to make sure I'm eating enough, since I'm not eating as much lately and I get panicked and hungry when I don't eat enough, and eat 3 meals. That helped a lot.
Then, my doctor told me NOT to try to lose weight at this point, the baby doesn't need me to gain a lot of weight right now in my first trimester but they did NOT want me on any kind of restrictive phase of the diet, so I should proceed to the maintenance phase of the food plan, and they would monitor my weight loss/gain as I add more fats/fruits/grains etc into my food plan going forward.
They said they would keep track of my weight and let me know if I should increase or reduce the amount of food based on what happens and how the baby's doing.
I was also told to take certain supplements (DHA, from a non-fish source) in addition to my prenatal vitamins...
So that's what I'm doing, though I haven't bought the DHA yet and I am seeing what happens, because I don't want to go crazy eating too much "maintenance food" and gaining a bunch of weight - I just want to make sure I'm not losing rapidly like I started out. Weird problem to have for a food addict, hah!
Anyway, if you read this and you're pregnant - or seeking medical abstinence of some kind, talk to your doctor about your situation. I found it very reassuring to finally hear from a professional.
