Having been diagnosed in July and jumping on that Everest like diabetes steep learning curve, I've become extremely cautious of people "selling dreams", without any specifics, or using wonky data. When it comes to extreme ends of dream scenarios being sold, we're not short of options. According to "experts" I've seen, we can all lead a healthy life eating carbs until we're buzzing AND cure diabetes, or nothing but meat until we burst without a drop of dietary fibre and not get colon cancer. Cholesterol doesn't matter, in fact the more of it the better providing you own an electron microscope to see if yours is fluffy enough, or we should only have a diet exclusively consisting of beans and lentils to keep cholesterol rock bottom, otherwise we'll definitely have a coronary in the next 13 seconds. We can only lose weight if in ketosis at all times, or we can only lose fat by not eating fat. You name it, whatever the health condition, there's an easy "cure" that's just one YouTube video view or paid subscription away, promising only upsides and no possibility of causing additional unrelated issues.
Generally speaking, if you want to justify a lifestyle route of any type, there's an "expert" out there with a PhD selling it. They can't all be right given the extremes of disagreement, but most of them have something to sell, or YouTube videos to monetise.
Apologies for the rant, I guess it's just me venting my frustration at a lot of the material out there on the wider internet that's attempting to prey on desperate, vulnerable people.
