Hello,
This topic is becoming a hobby fascination of mine and I've been reading a fair amount of literature on it, which naturally gives rise to some questions.
I have recently realised through a simple BG meter I inherited from my T2 diabetes mum, that my BG levels are slightly higher than what is considered to be normal. It seems to be exclusive to when I am fasting. I say this because on numerous occasions I have eaten the barely-imaginable filth that would cause BG's to rocket in just about anyone and tested my BG's within the hour only to find that it is still below 8mmol/l, whereas while fasting, I can get readings ranging between 6-7mmol/l (once it was 7.9 in the early hours of the morning 6-7am).
I initially put this down to insulin resistance, or a combination of other metabolic syndromes that I'm not fully aware of. To put things into context, my height is 190cm, I weigh ~90kg (BMI is around 25, but I'm more muscular than average) and I am around 15-18% bodyfat (at a guess). The only sign I show of having any metabolic issues is a persistent layer of subcutaneous fat hanging off my belly that has never seemed to go away, even when I went down to 85kg and was around 12% BF. I run long distances and have completed a marathon and I do cardio every single day in the form of biking, while maintaining gym visits for weight training at least 3 times a week.
Now in terms of the fasting, I have sometimes extended these fasts to 3 days at a time, drinking 0 calorie liquids and occasionally topping up my electrolytes and keeping my exercise at the same level as I would while not fasting. While I feel absolutely great by the 3rd day (ketosis, I tell myself, my definitely be highly active by then) I still manage to have BG readings of 6mmol/l. I definitely see changes in my BF visually by the 3rd day, and if I extend it further I would see alot more.
My question is, while I do not mind going for long periods without food, is this fasting practice actually doing my pre-diabetic state any favours? It may be important to point out that I am a habitual breakfast skipper too, and I've read various things in the medical literature about this practice inducing some kind of metabolic syndrome, but I don't understand the underlying physiological argument/basis for this. Can anyone also shed any light on this?
Sorry I realise my questions aren't totally direct but I was hoping to start off a discussion to help my knowledge along with certain issues related to this topic.
