The Condensed Eating Window Explained

by Dave on April 17, 2012

I had someone ask me today what a condensed eating window is. I imagine a few people wonder about it, so I decided to do a quick and hopefully simple explanation of it here.

Depending on the intermittent fasting diet  protocol you follow, the condensed eating window , is simply to the time you take in food.

Let’s take a couple of examples that use this process.

The Fast 5 Diet

The fast 5  intermittent fasting plan, works on a 19 – 5 protocol. So you fast for 19 hours, and have 5 hours in which to eat. So your condensed eating window  on this plan is simply 5 hours.


The leangains plan  works on a 16 – 8  plan, so in this case the condensed eating window is 8 hours and you fast for  16 hours.

There is no fixed rule for this eating window, again, you can either follow a plan the like ones I mention here, or simply adjust it to something you feel comfortable with.  I have played around in the past with a condensed eating window as small as 3 hours, again, usually between 5 and 8pm on Mondays and Tuesdays. There are no hard of fast rules here.

Not all intermittent fasting plans have a condensed eating window, for example eat stop eat  works on a 24hr fasting period, so no food is consumed during that time.  So there you go, a condensed eating window is just  a period of time you eat between fasts.

    I’ve tried fasting before but I find I always get pretty bad headaches. Is this something that most people stop experiencing after a while? I’m not sure if I should keep trying or just accept that my bodsy doesn’t agree with the regimen.

      did you build up slowly by steadily increasing the fasting period? This allows the body time to adapt to it. It’s like working out, if you got at it too suddenly you can burn out.

        Yes most who use fasting find the headaches stop, but make sure you are drinking enough water, often it’s a sign of dehydration.

        I had no problems with 24hr fasts when I started. The first one was harder, but it got easier as I went along.
