Good morning from the US MissMac.
My bad. Apologies for presenting you with a diet that is so dramatically different from what you're currently eating that it doesn't feel possible. You're not alone.
When I wrote that post, I was coming from the perspective of someone who had left employment two months weeks
prior to being re-diagnosed with type 2 diabetes, and who had chosen to not become re-employed until I got a handle on my "new" lifestyle post-diagnosis. Most people don't have that option.
Had my circumstances been different, it's highly doubtful I would have been able to start my new diet within three days time. For you, the place to start is beginning to think about where you can make small changes, eating healthier foods that you enjoy.
The paleo and low carbohydrate high fat (LCHF) diet are so similar, I studied both initially. The biggest differences is that paleo excludes dairy and grains, and LCHF excludes or greatly limits fruit initially if you have diabetes, though berries, and low carb fruits are fine for some of us, even those like me who have severe insulin resistance. How much the LCHF diet limits sugary and starchy foods varies greatly. It's highly individual. How insulin resistant you are determines this. I can eat a small handful of berries, but am still working up to eating a quarter of a peach. The good news is that as a type 2, I can still enjoy having part of a fresh peach because I can walk off the blood glucose spike - (a type 1 would adjust their insulin). Know that there are healthy work arounds.
I participate in a local diabetes group. Some of us switch to a whole foods diet immediately, others take 6 months or more to make the shift. Both approaches work. The latter just takes longer, and that's okay.
Up until my re-diagnoses of type 2 diabetes last year, I ate processed foods daily, and I loved sugary foods, though I'd already given up wheat, rye, and barley 4 years earlier when I was diagnosed with non-celiac gluten sensitivity. Switching to whole foods was a big change for me. It will be for you too.
I think the others are right. The first step is learning what type of diabetes you have, something that was never done for me. But know that regardless of what type you have, the diet will be similar. What will be different is the medical treatment you receive.
I'm glad you're taking a few days off to give you time to begin learning about diabetes and it's treatment. Your medical training will serve you well in looking at the different medical treatments available to you. And you'll also get great support here regarding questions about medications and insulins, also diet and nutritional supplements. I personally know next to nothing about the former, my focus is on the latter.
