I wrote about my experience of skipping lunch for a week. What do you think? https://medium.com/riccardo-parenti/fasting-and-productivity-what-i-learned-from-hacking-my-body-a398017db4b9
As someone who had health issues due to work/life balance, I'm not too keen on this idea.
I didn't read the article, and your experience with this kind of diet might be good, but we are not machines. You might hack your body, but you will hardly hack thousands of years of evolution. It will catch up with you sooner or later (and the later it happens, harder the hit).
Ladies and gentlemen, focus doesn't happen periodically or it has its own time schedule. Being able to focus is a skill you learn (or forget). Read "Deep Work" by Cal Newport. Block facebook, twitter or whatever is hot right now. Turn off your notifications. Set your phone to always be DND. Sit down, work and focus will happen.
I came here to read the article, but this comment is the meaning of it all in a nutshell. That's actually the one and only way to become productive.
And it does hit your health, both physical and mental. So I double this – skipping lunch for the work is not a good idea just because you get (and you need!) some rest during the workday.
I'd go even further and say even your comment while I agree with is pushing it. We can influence focus to an extent, but as said we aren't robots and FOCUS has no schedule, and we can entirely be PRODUCTIVE while "unfocused".
ok, but does fasting help achieving focus?
Fasting won't magically make you focus more easily, but it can certainly help with dampening factors that may hinder your ability to focus.
I will preface this as anecdata, but I have been following an intermittent fasting diet (16 hours of fasting, followed by an 8-hour feeding window) for nearly a year now. I have experienced marked improvements in my overall energy levels throughout the day, and lessened bouts of hunger in both frequency and severity—both of which directly impact my ability to initiate and remain in a state of productivity. On top of that, I've lost 34 lbs, regained healthy blood pressure levels, and (mostly) eliminated the frequent heartburn that I was experiencing. However, I do not attribute these improvements entirely to fasting—reducing excess added sugar in my diet has had a profound impact as well. I highly recommend the book "The Obesity Code" by Jason Fung for anyone interested in intermittent fasting. There is absolutely a healthy way to do it that is sustainable and maintainable as a day-to-day lifestyle. It also isn't nearly as restrictive as a lot of other popular diets.
I have also read "Deep Work," and by pairing that information with a controlled, heathy diet, I was able to create a reinforcing feedback loop that has had a significantly positive effect on my health.
Here are a few other great titles worth reading in the productivity realm that I have found insightful and valuable.
"Flow: The Psychology of Optimal Experience" by Mihaly Csikszentmihalyi
"Peak: Secrets from the New Science of Expertise" by Anders Ericsson
"Algorithms to Live By: The Computer Science of Human Decisions" by Brian Christian
Oh for the love of everything just DO THE DAMN WORK.
Why don't you just snack on small meals throughout the day? Nuts, yogurt, fruits etc., all of this is easy to eat in front of your desk and work at the same time. Getting smaller meals won't drain you like having a big lunch happening over a 1-hour time frame. Skipping lunch entirely can fuck with your metabolism.
Or maybe just don't take a 1-hour lunch break--pack your lunch ahead of time, eat it in 15 minutes, then get back to work. Half of my colleagues are doing this and their productivity doesn't "break"
