If you are a type 2 diabetic, you can eat your normal daily diet, which you are accustomed. It is not necessary to eat LCHF diet. However, you should control the portion size of your diet to less than 120 carbs per day, and take insulin/medicines of required dosage. This is my personal opinion only. I am 80 years old. I am having type 2 diabetes from 30 years. I eat cooked rice-vegetable diet every day limiting it to 120 carbs per day. I take 30/70 premixed insulin 40 units before breakfast, and 20 units before dinner. My bg levels are under control, except for occasional hypers, and hypos. I do not have any diabetic complications till now. I would like to invite the opinion/comments of the other members on this.
Objectives to achieve defines the paths to be selected.
On this forum we have seen that to manage DT2 there have been various paths that people have selected and many have been successful in meeting there objectives.
In your case you are satisfied with medication with normal diet so if that keeps you happy thats fine, but not for many who want to go back to medication free, self controlled life.
As we know two important component to control the excess of Glucose in body is, either to two cut down the intakes or if your body is capable of burning out the Glucose then workout to burn it out.
Later being slightly high hill task with not practical for many, in such cases Low Carb atleast opens up the path on intakes channel to meet the objectives. Hence there are plenty of success stories of meeting objectives on LCHF diets and thus people recommending here.
Having said that I believe everyone has to select his path based on objectives and it should have some short of balance between intakes as well as burning out the excess. Rather than relying on only single channel method.
