Eating within a 12-hour window

Reducing my time spent eating each day to a 12 hour window has had an instant positive effect on how I feel every day.

For as long as I can remember I’ve been able to eat as much as I want without putting on much weight. I guess I’m one of those lucky ones with a quick metabolism. (Smug face). It’s not unusual for me to have breakfast around 6am and keep eating throughout the day until just before bed, which could be 11pm. That’s 17 hours of eating, leaving only 7 hours of overnight fasting.

I was inspired to try a 12 hour on, 12 hour off eating routine after listening to Rich Roll talk with Valter Longo about Fasting for Longevity. Longo is a pioneer of research into human health and longevity through diet. He is probably best known for his Fasting Mimicking Diet but has conducted several fascinating studies about the effects of fasting at a cellular level.

He advises that a 12 hour eating / fasting daily routine is what we should all be aiming for. Eating for more than 15 hours a day is associated with metabolic problems, while fasting for longer than 12 hours is linked to gallstone formation and an increased risk for overall mortality.

So I’ve been giving it a go. This means that I might eat my last meal for the day around 6pm which has taken some adjustment. I can honestly say I’m feeling more energetic since restricting my eating to 12 hours a day. It’s also helping me to meter my daily calorie intake, and most importantly there’s less washing up in the evening!

Hope you all have a great week.
