My anecdotal experience is that I already have sleep issues due to adhd related insomnia. Fasting for sure makes it worse at first if I don’t fast for awhile. I’d say that my quality of sleep in the amount of time I get sleep has improved a lot. But I’m not sure if it’s the mechanics of fasting helping or just my improved health and diet. When I do extended fasting I have to keep up supplements and exercise or I don’t sleep for 2-3 days at a time.
Actually you’ve just reminded me that I need to get back on the fasting train (I’d fallen off) because my sleep was so much better when I was doing 16:8 I stopped eating around 7 or 8 pm and was a lot better for it.
This is what brought me to IF! I was having insomnia and I ended up going to my doctor to talk about treatment. I didn’t want to go on sleep meds, so she suggested (along with other strategies) that I try intermittent fasting. And voila, I slept! I fully admit it could be psychosomatic and because I believe it works, it does. But either way, IF has really been a game changer for my insomnia!!
I sleep consistently better when fasting. I stop eating quite early (14:30) but do have a hot drink and some ACV and lemon water (with hot water) at around 18:00. I find my body is happy to sleep to get the hunger over with, lol. Now I’m hoping I haven’t jinxed it! Hmmmm…. It may also be that my body knows what to expect? Like I still go to bed and get up at pretty much the same time whether I’m working or not as well.
