Rice crackers were okay (I don’t eat them much anymore, as I am getting most of my carbs from veggies, fruits, dairy, chocolate). Just basic rice crackers, check ingredients for least amount of additives. I do like Trader Joe’s Sea Salt & Peeper Rice Crisps, but that may be too spicy at first. Popcorn chips were okay, or homemade popcorn (not microwave), but go very easy and chew thoroughly.
Look for low FP, high carb foods like butternut squash, parsnips, rutabaga, etc., and make sure to have a fat & protein with it to slow down the blood sugar spike. So have some cream cheese or olive oil & bit of meat with the rice crackers if you aren’t doing
80g carbs a day average works for me (so 60-100g. range, but the steadier of close to 80 I feel best), and is not a lot of calories compared to the US average of 150-300g or more per day.
I have resolved my much of my thyroid issues with diet as well, but that is a whole new thread. 🙂
