I'm a T2 diabetic who took over 300 units of insulin a day. Within the first month of eating VLC, I got down to just 20 units per day and now I take none (unless I get sick, overly stressed or have a major diet failure and eat carbs). In the first six months after I started eating a VLC diet, it would take me up to two weeks to recover from a high carb meal, during that time, I had to significantly increase my insulin dose. If you don't have insulin available to take, I highly recommend not eating a high carb meal, you may really struggle. I also recommend making sure you have some insulin on hand or accessible via prescription for situations beyond your control - in particular illness and stress, which can both cause your BG to rise excessively. Some studies have shown that people can reverse diabetes and go back to eating some carbs, but for most of us, it's more of a situation where we're able to get off our medication and manage our diabetes with diet instead, meaning we're still diabetic and still have to work hard to keep our BG under control.
