I haven’t read the artical yet but doesn’t everyone fast overnight?

Many people snack right up until bedtime (sometimes even literally in bed) and then rush to feed again the second they wake up. So technically, there is a fast during sleep, but technically, there is a fast every second you don't have food in your mouth, I suppose.

The point is, duration is important. I don't know if there's a standard, but in the intermittent fasting literature, 18/6 is one of the common schedules, so you'd eat from noon to 6pm for example. The other 18 hours would be 0 calorie intake hours.

Rather than fixed schedules, what you need is a period of time long enough that your body enters ketosis rather than using energy directly from glucose. The schedules are a rough guideline.

Surely that is an eating disorder or beginning of one?

I am not sure. I have a sister who used to do that and she wasn't overweight neither had any obvious eating disorder. Maybe it was because she was an athlete? I know other people with obvious weight problems that wake up in the middle of the night to eat and maybe for those it might be considered a disorder.

> athlete

I've heard of strength training regimens that call for a middle of the night protein shake supplement. But given how crucial rest is, I've always been skeptical of that idea.

I see what you did there. Good use of the period at the end!

I know. I was being humorous!

Indeed, overnight fasting can really extend healthy lifespan and this is a proved fact. The secret is not to fall asleep starved, but to eat vegetables and fruits. On the morning grab a good / consistent meal,

afternoon eat well one more time and this is it! Your body will have time to digest and rest. I hope it helped you! Cheers.

I've tried a few variations of fasting over the last ~3 years and here's what works best for me. Because I tend to snack, I have time-boxed my eating windows inline with a fasting schedule, so: - No breakfast, just black coffee - First eating window (~11am - 2pm) - Second eating window (~5pm - 8pm) - No eating after 8pm I've played with three eating windows and it also works quite well. I cheat on weekends, Fridays a…

I found eating at 2pm and 8pm worked for me. In the morning, if you don't eat, your digestive system seems to remain inactive so you're not that hungry until 2pm. By eating at 8pm you're eating late enough that you'll be asleep before you get hungry and want to snack. This gave me 18 hours of fasting, 12 hours digesting the last meal and about 6 hours of my body burning my fat stores for energy.

I combined this with reduced carbs so when I did eat, it was a longer time before I felt hungry because reduced carbs means not getting the sugar rush and then the crash a couple of hours later where you feel very hungry.
