Hi M. S -
Diabetes is sadly becoming very common, and it's completely preventable. I don't want to be the "Scary advice Mom" but you seriously need to reduce (if not eliminate) most of the sugar you’re eating. If you don’t, then there is a good chance that you and your baby will have complications from the big D word. (diabetes) What has happened is that you have dulled your insulin receptors by eating sugar in high quantities. This isn’t uncommon, and it is definitely reversible. Once you dig your heels into a new way of eating and get rid of the sugar, your body should go back to being able to handle LOW amounts of sugar in the normal way. Your insulin response is screwy, but you can fix it. You NEED to fix it.
There are a few things that you need to keep in mind when making choices about what to eat: your body treats carbohydrates, sugar, sugar substitutes, and natural sugars from fruits and veggies in the same way. Once it gets into your tummy, your body can’t tell the difference, so it produces the EXACT SAME insulin response. Sugar substitutes might not have any calories, but you're not trying to restrict the number of calories you eat; you’re looking to reduce the insulin load.
Just eat natural foods. Shop on the perimeter of the grocery store - vegetables, fruit (in small quantities), meat section & eggs. Don't eat anything from a box or bag. (unless it’s raw nuts in a bag)
Start with the basic stuff - we use our slow cooker/pressure cookers a lot. We do all our grocery shopping on Sunday, and make a rough plan for the week. This helps you stay organized. "If you fail to plan, then you plan to fail" It'll be easy to feel tempted to just boil some noodles instead of taking the time to cook. If you find yourself in a pinch, have some tuna with olive oil/balsamic vinaigrette on it and a handful of nuts.
Phew....man I talk a lot! Sorry to overwhelm you...this is just something I know a little bit about. My husband is super smart and knows all about the scientific end of the spectrum, so we can always bounce questions off him if you need to. Unfortunately most doctors don't know a lot about nutrition. They might spend a few hours learning about it in Med school, but most don't take the time to delve deeply into it...hence the reason most Doctors give the SAME (and WRONG) dietary advice.
