I have been browsing this (very long) post for a while and suspect my answer is buried But nothing jumped out so here's my question.

I have been pleased with my use of IF (16:8, with the 8 hours starting at midday). Given that I am someone who likes to nibble through the day (and traditionally doesn't have the strongest of wills!), I have been amazed at how easy this has been for me and now have no issue whatsoever getting through the 16 hours. In the 8 hours I have pretty much anything I like (though I do tend to eat reasonably healthy food, I guess).

In the last 5 weeks I have lost 9 lbs, which has really pleased me. I am about 5 lbs off where I want to be for a big ride I have coming up in a couple of weeks (the Whistler Gran Fondo Forte). But now I am starting to think about the day itself.

Given that there is an early start (around 6am) and Cypress Mountain is early in that ride, know I won't want to be doing that while fasting.

So, with that said, how much of a shock to the system is it to deviate from what, by then, will be 2-3 months of not eating till midday? Is this something I should gradually transition out of, leading up to the day, starting around now (12 days to go). Or is it feasible to just not worry about it until 2-3 days before and stop the fasting at that time?

By the way, after the ride I fully intend to get back to IM within a day or so. I can't actually remember trying anything that has dropped the pounds so easily!

Thanks!
