Thank you for the link to the article. It really made me rethink the 16:8 thing. When I tried it before, I overthought everything too much and was too rigid.

The whole idea of just delaying breakfast a couple of hours and eating dinner a couple of hours early plus having a more flexible window makes it seem so much more doable! So I am doing just that today, a non-fast day for me. I had my first food at about 10am--some peanuts at bowling, then 1/3 apple, some brie and crackers at about 1:00 pm, some "Drunch" (dinner/lunch) at about 4:00 and nothing since. It is now almost 10pm and, although I'm hungry and would love to eat something, it's no big deal. I'll live.

Tomorrow is a fast day, so I'll try to keep a similar window. Because one of the reasons I started 5:2 was to stop incipient Type 2 diabetes in its tracks, this seems like a worthwhile refinement and one that might help make maintenance easier. So, we'll see how it goes.
