I’ve been reading Tim Ferris’ Tools of Titans, and I love it!

Great book with lots and lots of practical insights in all different areas.

One of which was something, which I never thought I’d do. I fasted for 50 hours.

  • that means no food at all for 50 hours



Apparently, fasting has lots of health benefits:

  • Cellular repair: The body induces important cellular repair processes, such as removing waste material from cells
  • Gene expression: There are beneficial changes in several genes and molecules related to longevity and protection against disease
  • Insulin levels: Blood levels of insulin drop significantly, which facilitates fat burning
  • More hormones: Higher levels of this hormone facilitate fat burning and muscle gain, and have numerous other benefits

How did you do it?

I had lunch on Wednesday and then basically stopped eating. No food, only water. In the mornings I had a spoonful of coconut oil (which was at the time the best amazing thing), which was to replenish energy levels (and recommended in the book). That’s pretty much about it – don’t eat.

How was it?

It was awesome to see, what your body is capable of.

On the first day, you get super hungry, at exactly the “right” times – when everyone goes for dinner, coffee or lunch and your brain tells your stomach “oh, it’s food time!”. The first 20 hours are tough – your stomach grumbles, you only think about food and you’re not sure if you can do it.

Getting out of the bed the next morning is difficult as well, but once you’re up and going. You feel great! You feel like you’ve owned your body. I was very focused, it feels like all the background noise is suddenly gone.

The second and third day are actually not that tough. You realise how much of people’s lives revolve around food, but you don’t feel excessively hungry yourself.

How did you break your fast?

I bought 3 cheap lunch boxes on sale, had a couple of beers and went for Italian food afterwards. That’s probably not the best way to break a fast, but the reason I tried fasting was not for weight loss reasons, but purely out of curiosity.
