As a routine part of my life I fast every day, and have for a long time. I did not know this was a new thing until I started reading about it in article.

I normally don't eat anything after 4, 5 or 6 (and if I go to a later lunch at 2 or 3 to a restaurant, won't eat again until mid morning the next day), then fast for 12-16 hours, not on purpose, but I feel better eating earlier and don't like to go to bed on a full stomach. I never eat three meals a day, but prefer to graze. I am of slender build and stable weight and excellent health, lifelong, and there is no need for me to watch every calorie.

I exercise daily and eat well, but the restricted time eating has done nothing to help me get to sleep easier at night (which started in my early 50's 10 years ago). Glad to read it helps some people, and maybe the in general mindfulness of eating can also assist some people.

Your mileage may vary!
