Well, I don't have to. But I am trying to anyhow as whether I am pregnant or not, I do gain weight if I overdo the carbs. I also love ice cream!
Just eat loads of protien and veggies. For breakfast have eggs, steak, etc. Maybe veggie omellettes. Stay away from cereal, icecream, and even try not to eat more than maybe 1 serving of fruit a day. Mostly stay away from processed carb foods...the white breads, cookies, tortillas, ....also stay away from soda, candy, etc. And make sure to get enough good fats ... not the icky transfats. Your baby needs healthy fats to grow, and good fats like coconut oil, real butter, lard, etc stabilize blood sugar incredibly well. A little olive oil is good too, but not a lot. You need saturated fat. Include a good source of fat with every meal and it will slow down the sugar response in your meal. I had borderline GD last time, and this time I did not and I know my healthy diet is a big part of that. I did insist on doing the post-meal glucose screen though because I don't believe the glucola drink is accurate at all. Actually I don't even think the whole GD diagnosis is at all helpful, but that's another story.
Also, exercise! Up until about a month ago I was exercising about an hour 4-5 times week. Now it's down to about 1-2 times a week
: It will not only regulate your blood sugar, it sure feels good to get moving...even if for only 20 minutes at a time on the treadmill or doing some prenatal yoga.
