It’s very confusing when you get the diagnosis and such a shock, too.
Low carb eating is a huge asset...low carb, high fat. Has a huge impact on blood sugars. If you can do a bit of intermittent fasting as well then all the better. It’s all about not spiking your insulin levels.
It’s great that you’ve got a meter, too, so keep testing.
I would also question taking the metformin......did your doctor not give you the opportunity to make changes to your diet first? Personally for me I refused them and my GP was happy for me to make positive changes to my diet, which I did. I managed to bring my hba1c down and lose weight and put my diabetes into remission. So was there any need for the Metformin? Just a thought...I obviously don’t know your personal circumstances.
There’s a huge wealth of information out there....books, YouTube..so it’s relatively easy, if somewhat time-consuming, but worth it, to learn about your situation and make decisions about how you deal with your diabetes. Dr Jason Fung on YouTube is very interesting. The ‘Diet Doctor’ website was my ‘go to’ when I first started researching Keto and LCHF.
I have no faith in the diabetic nurse at my practice with her outdated nutritional advice..which is laughable. You would be better doing your own research via the internet and the diabetes forums.
But definitely lose some of the carbs from your daily diet...you’ll be amazed!!
