I'd been low-carb for almost a year, and Primal for the last 7 months of that before I tried fasting.
I'd lost ~30 lbs by this point. My weight loss had stalled for a couple of months, but, seeing as it was within 5lbs of my goal weight, I didn't worry too much. At this point I'd already moved from eating three meals a day to just lunch and dinner.
It happened without thought or effort. The Primal diet just kinda did it to me.
Making the change to a five hour (5pm to 10pm) eating window was pretty damned easy. I now eat one meal a day on most days. I'll snack on 90% chocolate and cheese if I want during the rest of the window (after dinner). Um...and red wine.
Anyhoo...the results. I've been Fast-5ing for about 60 days. I now weigh 3-4 lbs below my goal weight. I've had to come up with a whole new goal weight. Terribly inconvenient. The love handles are dwindling and I hope to see the end of them in the next few months.
