Hello!
If you don’t know how to count carbs, you’ll need to contact your diabetes team to refer you to see a dietitian. As time goes by and with more insight and experience, ask about a carb counting course for dose adjustments. The carbs and cals book or app is a good start to learn about it. What I will say though is even with low carb, you’ll still need some insulin for it. There have been type 1 diabetics that have said some proteins have increased their BG ever so slightly. This happens when I eat some eggs and some salad & of course insulin is not a lot for it but it still needs some. Basal-bolus regime will give you more control, so hopefully less low readings for you.
