...went low carb. After 12 weeks I had lost 9kg and my diabetes was in remission. ... I am very confused as to what I can now I eat. ...
In the meantime, in immediate practical terms: I think maybe what's most needed is clarity about the distinction between managing Type 2 and 'going into remission from' Type 2.
As I understand it, the distinction is as follows:
Type 2 is caused by excess visceral fat making your body's cells 'insulin resistant'. Insulin resistance is the defining characteristic of Type 2 diabetes. Most of your body's cells need insulin in order to use the glucose in your blood. So, if your cells become insulin resistant, they don't absorb enough glucose from your blood, and therefore you have persistently, abnormally high blood-sugar levels.
Type 2 diabetics can often manage this by eating a low carbohydrate diet. This will have the result that, even though they still have the excess visceral fat, so their bodies are still insulin resistant-- meaning they are still unquestionably Type 2 diabetics-- their blood sugar levels stay low. (Because your digestion turns carbohydrates into glucose and pumps that into your blood. So, if you eat very little in the way of carbohydrates, you won't have high levels of glucose in your blood in the first place-- so it won't matter so much if your body's cells are still reluctant to suck up that glucose.)
'Going into remission' from Type 2-- or 'reversing' or curing Type 2-- means losing the excess visceral fat so your body stops being insulin resistant. In that case, you don't need to eat a very low-carb diet anymore: your cells have returned to normal, responding normally to the insulin your body produces and sucking the glucose out of your blood properly.
You do however have to keep the weight off, and especially keep from gaining excess visceral fat again. The key to keeping the excess visceral fat from coming back is exercise. So you need to do regular exercise, and also keep your calorie consumption moderate. (It is possible to be overweight and not have excess visceral fat-- but of course if you are overweight you're far more likely to have excess visceral fat.)
If you have the kit for testing your blood-glucose levels, you can experiment with this yourself. Try some higher carbohydrate-- but still healthy and not too high-calorie-- meals, and see how your blood-glucose levels respond. This will show you whether you have really 'gone into remission' yet, or whether you still need to stick to a low-carb diet while losing more weight and getting more exercise.
