I too agree with Sid - it is always best to check if you have other health problems before changing your way of eating, and I hope your doctor is open-minded and will discuss things with you and give you reasons and explanations so you know exactly where you are.
The only thing I would add, is that the best cholesterol/lipid profile readings I have ever had were when I was eating Atkins Induction Phase low-carb, which I did for 18 months, 2004/05. This was before I was diagnosed Type 2. I had no other health problems at the time, and I had discussed "doing Atkins" with my GP before starting it. I was monitored by my GP every step of the way, for blood pressure, blood glucose and cholesterol, all of which came down, and I lost 70lb.
If there is any chance of kidney or other problems - check with your GP before starting. Check with your GP anyway!
I replied to your other post without realising you had raised protein levels. It is perfectly possible to reduce your carb intake by reducing the starchy carbs and replacing them with lower carb veg such as salads, cabbage, cauliflower, broccoli etc. to satisfy your appetite. You don't have to go overboard on extra fat and protein.
Good luck!
