I had a HbA1c of 88 when diagnosed in April, and reduced it to 32 after 3 months by adopting the LCHF lifestyle. It's easy once you get your head around it.
Just cut the carbs out of your diet, they are the killers.
Absolutely, after years of being told to have low fat to lose weight and cholesterol, it takes some mind shift. If you look at eating clean, this will be very similar as this way of eating is to cut out all processed foods. I 'high fat' with full fat milk, butter, avocado, meat, nuts and seeds. I don't have lashings of cream (but I will have some in coffee) and I don't have vast amounts of cheese. I still need to lose a couple of stone so this is my way of managing. I think the higher fat will come when I need the calories to maintain weight and keep myself satiated. I am not counting calories, I don't need to now, as eating this way is less complicated than traditional dieting. And the blood sugars… yeah they are so much better.
