Hi I have been eating 20g or lower each day since September 15th, I woke at 1am to pee which was unusual for me, tested bg at 24, so decided I needed to try and fix my erratic numbers, I haven’t eaten many carbs for years and years but decided lowish carb wasn’t enough, I would go from hypo to in the 20s and yo-yo up and down, my libre chart looked like the alps, I tried everything from timing to dosing to correcting, they all worked! But they all worked too well or not well enough so the rollercoaster continued.
I also discovered intermittent fasting, When I say discovered, I knew about it for ages but considered it bananas, I have found it life changing! Very low carb and IF now mean my numbers are flat, I still get a bump in the morning from my dawn phenom but I correct it with very little insulin, my Insulin has gone from needing around 60 units a day (levemir/novorapid) to 10, I don’t spike, some meals I don’t even bother injecting for as my basal seems to cover it, I think because my 1 or 2 units for My meal is low I don’t or can’t over or under shoot very far, the timing is less important, my libre line just wobbles.
I am very strict with both keto and IF, I never cheat, even over Christmas, I have no idea why but I find it very very easy to stick to, of course not so easy at first but now it’s a doddle, I am 53, before September I felt 63, now I feel 43, it’s incredible.
Best of luck to him and well done you for trying to help
