Long time readers will know that I keep to a six hour eating window during the weekdays (1:00 and 7:00pm). At the weekends, I’ll usually eat breakfast at a conventional time (Naked bacon and Naked sausages and eggs) and skip lunch.
I played around with a smaller eating window last week. My window was from 5:00 to 8:00pm. I did it for two days. The one exception, and purists feel free to pile in on me, was cream in my coffee during the day.
What were the results? Unsurprisingly, my energy levels were fine given that I’m used to fasting. I was sort of busy during the afternoons on both days, so I didn’t miss my lunches too much. I was going to go for a third day “in the window”, but I found myself very hungry at lunchtime so decided to eat.
Blood glucose? Not a big surprise, but it came down a bit compared to previous days. Since I was pretty much on a twenty-hour fast each day this was to be expected.
A duckduckgo search or a browse around Youtube reveals all kinds of people arguing for tight eating windows. I see their point, since it is a form of intermittent fasting, and one would likely reach autophagy from time-to-time. Still, I can’t see myself adopting this as a lifestyle. Once in a while. Sure. Every day? No chance.
Why not? I tend to feel hungry at lunchtime. I also get to eat lunches with my wife, and I’d miss that too. Given that I do skip meals all the time and have several fasting days each month, I don’t think a super tight window is going to bring any new benefits.
When I read Mark Sisson’s The Primal Blueprint all those years ago, one of the most compelling arguments he made for paleo was that once you were through the carb withdrawals you could eat whenever you felt hungry. The fact that my diet is very high fat, I don’t tend to feel hungry that much. However, if I’m hungry at lunch, I’ll eat. If I’m not, I’ll skip. That’s how I’ve lived for years. Except for fasting days, this will continue to be my philosophy. Good luck to you super tight window people, but it’s not for me.
