Firstly- thank you all for your assistance and adviceHi and welcome from me too
I am not sure any of us would necessarily recommend a high protein diet for diabetes anyway. Some might suggest you can eat more protein to replace the carbs but most of us cut back on our carbs and just eat a bit more fat but keep the protein the same. The Low Carb, Higher Fat or LCHF way of eating is probably the most preferred and successful way of managing diabetes through diet here on the forum and on a long term basis, it is reasonably sustainable from the point of view of being relatively easy to stick to once you get the hang of it.
If you read around the forum a bit I am sure you will get the idea but if you find you don't understand anything, just ask.
What medication, if any have you been given for diabetes and do you know your HbA1c result? This is the blood test result that they use to diagnose diabetes and will usually be a number of 48 or higher. It gives you and us an idea of where on the diabetic scale you are, so that we can give more appropriate advice.
