Circadian Rhythm Fasting – A NEW Approach to Intermittent Fasting


I pride myself on spotting health and fitness trends early on.

There’s a small trend that has been growing the past 5 years that I think will be HUGE in 5-10 years from now.

This topic is also a major focus of the 2020 Global Wellness Summit.

The summit takes place in Tel Aviv, Israel on Nov 10-13.

One of the big topics of the summit this year is “true circadian health”… which is something that I believe will become mainstream in 5-10 years.

Here’s a link to a massive article on some of the things that will be discussed.

Way deep down in that article, there is a section titled “The Circadian Diet”.

The first section discusses how Intermittent Fasting was the most searched diet term in 2019.

I’ve been writing about Intermittent Fasting since 2007, but the general public is about 10 years behind scientific research. Scientific research also shows that the KETO diet is not a healthy long term diet, which is why I recommend a low fat carb-based diet.

Back to the article…

A study found mice live 15 percent longer when eating in a time-restricted feeding window.

We have known this for a while.

If the 15% increase in lifespan applied to humans, it would mean increasing lifespan from 80 to 92.

One question looked at in the article…

Is Intermittent Fasting effective because of the “intermittency” of eating, or COULD it be that the fasting is circadian-synced?

It has been suggested that syncing up mealtimes with circadian rhythms leads to greater weight loss.

We process more calories when it is light out, like in the morning and day. You can look at this info in a couple of ways.

  1. What the article suggests is that you should eat more of your calories in the morning and day since you are burning more calories.
  2. I actually like the idea of NOT eating during this time to force your body to use fat for fuel instead of calories from food.

Since the body really does slow down at night, it DOES make sense to not eat a huge meal right before going to bed.

don't eat before bedtime

You are probably familiar with this saying:

“Eat breakfast like a king, lunch like a prince, and dinner like a pauper.”

The small dinner idea does make sense to me.

I just don’t think you need a huge breakfast.

I could see, on paper, how fasting until 1 PM and eating your largest meal at THAT time could be optimal when it comes to your circadian rhythm.

You would be burning fat in the morning…

…and still taking in calories around lunchtime when your body digests them easily.

Maybe LUNCH is the most important meal of the day?

As I’ve discussed in the past, I tend to eat my largest meals at dinner.

I do this because it works best socially for me.

I enjoy large dinners… but If I’m being honest with myself, eating a larger meal earlier and then eating a smaller meal for dinner is probably best for fat loss.

I’m still able to get and stay lean with a large dinner.

This works for me.

…but maybe I’m making things harder on myself by doing so.

“Light Eating” = Eat when it is light out and stop when it is dark.

This is a new way to look at the term “Light Eating”.

Looking at Intermittent Fasting from a circadian rhythm perspective could be interesting.

Eat Stop Eat is, by far, the most comprehensive course on Intermittent Fasting.

For those of you who follow this approach?

Maybe test out eating your meal earlier in the day.

For those who do a 16:8 intermittent fasting method, where you limit eating to an 8-hour window?

Perhaps make that first meal large and taper it down in the evening.

We obviously have a lot more to learn about this stuff.
