Cracked wheat uppuma was good too. As far as food goes, everyone's body reacts differently to different types of carbohydrates, so you really need to experiment. Cheeses are great, snacking on carrots, celery, cucumber works as well, nuts are good too. Soy is also a great alternative. Stir fried tofu is a low carb and very filling meal.
Avocados work well too.
Mom's salad was a huge platter of many veggies chopped really fine with some spices. I actually used to eat it in lieu of rice. In the last month I had nonstress tests and ultrasounds almost every week to make sure that baby was OK, and wasn't growing too large. I went into labor 2 days before my due date. I was in labor for about 15 hours, I wasn't allowed to take any juice bcos of the sugar.
