I'll ask the Varsity Paleos not to turn up their noses, here...
IF is touted as being "the way to go" along with Paleo. I have never yet been able to do it. The problem is me, I know, not IF. If I could manage it, even Fast-5, I think it would help me get off the few-days-virtuous-one-day-sugar-hit roller coaster I'm on.
Part of the problem is a list of supplements I take to avoid having to deal with the Drug Lords down the line. (I've dealt with cancer three times, so I take the proactive approach to life at this point.) Taking the supplements without food gives me roaring nausea and pain. My brilliant alternative MD says that taking them every day is what builds up their usefulness.
If I never do IF am I missing most of the boat here? I feel hugely unsuccessful at this point, even though there are stretches of days when I am 100% on it, and I've maintained the weight loss I first managed when starting Primal/Paleo last year.
