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. My fbg varies from 70 mg/dl to 110 mg/dl. My ppbg varies from 140 mg/dl to 250 mg/dl. The high ppbg level gets reduced to near fbg level in about 12 hours. I do not have any diabetic complications till now. I would like to invite the opinion/comments of the other members on this.
