I do the same, but this week I've slacked off and now my weight loss has stalled. Still carefully watching carbs and calories, but this week I've made no progress (no gain either, but I feel like I've wasted a week when there's no loss). I read in Taubes' "Why We Get Fat," that IF often helps people break weight loss plateaus, so I guess I'd better get back to it. I was doing 16 hour daily fasts.
