I typically eat breakfast around 8 A.M., supper about 6 P.M. and nothing else in between. So, I go approx. 10 hours between morning and evening meals and then about 14 hours overnite.
I don't like to eat any earlier if I can avoid it. I suppose I could wait until 10-11 A.M. to eat breakfast and that would stretch my overnite fast to 16-17 hours.
But, I think my biggest problem is I'm a carboholic. I love bread and rice. I don't booze it anymore (dry since Spring of 2013), so there's that.
Also, I didn't fast before my last A1C test and, even though the doc said I didn't need to, I'm suspicious. That was the first time I've had blood drawn after eating and the first time my blood sugar's been that out of whack. Dunno.
