Week 7 Day 47 Friday 26th January. FBG 5.8 Weight 98.2kg
Quite funny that seeing a high five for the blood now looks a bit odd. Just a couple of months ago I would have been over the moon to see a number that low. I suppose it shows how much more control I have these days. It's convinced me to leave the insulin level as it is as there's still some small weight loss. Psychologically a 97 would be very welcome - maybe over the weekend - as it puts the target of 96 within reach. For me, despite all the other progress, 10kg weight loss has become something of a success indicator and I feel I need to get there. I'm sure I will.
Lower fbgs, returning sensation to feet, loss of body fat - all good, congratulations!
I'm no longer doing the ND 'with you' I'm sad to say. I quickly realised that, yes, after 2-3 days you start to feel good and I was even going on 1 hour walks in the evening. But I didn't feel I had the energy (nor would it be safe) to go on bigger walks at weekends and certainly not into the mountains.
I've started the 5:2 fasting idea, and already had my first 600 calorie day (all in one go) with no further calories till the next morning. Went well, and by the evening my bg was down to 3.7. A bit scary, so rather than go to sleep on that, I lifted some kettle bells just to see if my liver remembered what to do when bgs get low - it probably hasn't had to cope with that situation for years! Sure enough it climbed again. Went to bed, and woke up with a 3.9. Previously, I'd been getting similar fbgs to you.
The diet is LCHF and I'm aiming to quickly transition to keto, so it will be a 5:2 keto diet.
All I know so far is that, after the fasting day, then a couple of days of normal feeding (I did calorie count, and hit about 2,200 each day), I then had plenty of energy for a big, strenuous (i.e. often steep) walk lasting 5.5 hours. Felt very good at the end of it.
Obviously fasting isn't a great idea if you are on insulin, but you seem very in control and able and willing to switch the parameters, so just letting you know, as someone in a similar position to you, that there are other options to explore if you feel you've exhausted the potential of the ND at any point. I've never seen an fbg of 3.9 in the morning until I tried fasting. I'm hopeful the approach will lead to weight loss also, the idea being that the full-calorie days keep your metabolism up, plus will enable me to do the kind of hobby I enjoy which happens to burn a ton of fat.
I wish you continued improvements till the end of the ND, and with whatever you try after that!
