I still haven't tried to go longer than 23 hours or so, but I am doing a pretty good job of sticking to one meal a day. (OK, I'm having milk at 1pm, and then dinner with my family.)
Sometimes if I'm at work late (well after 6pm) I will have a handful of mixed nuts before I get in my care to go home. If I have a rough day I will have three handfuls of mixed nuts. Other than the latte during my 1-2pm lunch hour, I'm having nothing but water and tea, maybe black coffee with a tiny splash of half'n'half. My office mate is eating hot lunch at our shared desk (it's side by side, it's really something to see).
Weight loss has been just OK. I dropped 5 pounds pretty quickly, then plateaued forever, and more recently have starting losing again. I'm about 7 pounds down at the moment. I'm fitting into smaller pants (but I feel like I still have a ways to go on this.)
I continue to prefer this as a strategy. It's still much easier to simply amputate any thoughts of eating as they occur (I just think "nope") . . . up until dinnertime. I was on an inexorable weight gain pattern, so even slow weight loss is good. I really enjoy eating, and I'd rather have one awesome meal than three sad ones.
