What Time to Eat?

I usually write about what to eat, but timing is important too.

Your body doesn’t just gear up to sleep when it’s dark and wake when it’s light; every part of it has control clocks.

Artificial light means we can eat from pre-dawn until midnight nowadays. Unfortunately, this disrupts our circadian rhythm and is bad for our health.

It’s best to eat during the day when levels of digestive enzymes are high and your liver and gut are ready to deal with food. In the evening, saliva production slows down.  Also, if anything enters the stomach, there’s more acid produced. Your gut slows down for nightly repairs – but repair is difficult if food is still passing through – it’s like trying to re-tarmac a road with traffic still flowing. It’s better to stop eating 2 or 3 hours before bed.

I’m in favour of working with your body, so Prof Satchin Panda’s research on Time Restricted Eating struck a chord. (Listen to Dr Rangan Chatterjee interviewing Prof Panda here.)  An 8-10 hour window has been found in the lab to protect against (and to improve existing) obesity, heart disease, diabetes, fatty liver disease, cholesterol and high blood sugar. Prof Panda recognises that we don’t have a choice when we get up; we have jobs to go to and children to take to school. But we can choose when we eat.

I like to try things out.  Initially it felt weird starting work early then having breakfast at 9:30am but months into my self-experiment, I feel great. After 7:30pm I don’t eat – that’s a 10h window. Even a 12h window gives benefits, say 7am to 7pm.  Give it a try and find out how you feel working with your body’s rhythms. (Check with your doctor about effects on medication.) There’s also a global study you can take part in via an app (mycircadianclock.org).

Quote of the Month

Time is a created thing.

To say, ‘I don’t have time’ is like saying, ‘I don’t want to.’

Lao Tzu

One of the reasons that people give for eating processed food products instead of making real food from fresh is the time that it takes.  Keep an eye of the adverts you watch and you’ll find that a theme running through many of them is that you don’t have time for anything and the thing they’re selling will solve that problem.  We’ve swallowed the myth that we don’t have time to feed ourselves well.

Set yourself free from that.

You can always make time for what’s important to you.
