Hi,
I read on an LCHF forum that someone on strict LCHF may get “glucose spikes” if suddenly consuming great amounts of carbohydrates, as the body is not used to dealing with such amounts of carbohydrates after a while on this diet. The levels (measured by a blood test) would then quickly drop and become normal again (= typically low for someone on LCHF). I am not practising LCHF; this is just where I read about it.
Is there something similar experienced for 5:2? I would guess that the sensitivity is less marked as it is not an on-going reduction of carbohydrates but only twice per week and depending on how you get your calories in general (from carbohydrates, fat or protein).
I had a routine blood test at work this summer and was a bit surprised that I had a glucose level = 4.7. This is still a normal value but quite a bit higher than the typical 3.8-4.1 that I have “always” had.
Then I realised that I had had quite an unhealthy meal on the previous evening with loads (I really mean loads, for instance a big bowl of popcorn) of carbohydrates. I also had been unable to exercise as much as I normally do due to a cold so I guess that I did not burn off the carbohydrates the way I normally would. I have always had a high carbohydrate intake and still always kept the glucose levels above.
So, to make a long story short, is it possible that the body reacts a bit more to “bursts” of carbohydrates (especially when these are of the more refined sort) when your body has got used to the 5:2 diet, especially after a fasting day? Would measuring the long-term glucose be a safer bet than the fasting glucose you normally check to establish your insuline sensitivity?
I will check the values now again in October and I am not worried in any way about this result I had; I was just surprised to see it!
Thanks for any input.
