I was seeing if I can get away with my favourite breakfast which is porridge
Even if you “get away with” porridge it is quite possible it is taking its toll on insulin levels which we can’t measure ourselves. Carbs raise blood glucose levels which need insulin to be brought back down. Some are worse than others and it’s not the same for everyone.
Prediabetes, metabolic syndrome and type 2 all are characterised by chronically high insulin levels desperately trying to maintain normal blood sugar levels. These high insulin levels do their own damage and contribute to insulin resistance making the whole problem ever increasingly worse. Until eventually the underlying problem of insulin resistance is bad enough that even the incredibly high levels of insulin just don’t do the job either and blood levels rise enough to be detected and ultimately become type 2.
It’s your choice whether to push what you can get away with or not. We all make choices that are less than ideal sometimes. But knowing that we are doing so is important. I try not to do things likely raise insulin levels in order to allow my very stubborn insulin resistance to heal. I’m human though and don’t always manage it but I wouldn’t do it daily, especially when there are simple alternatives that I like just as much.
