I don't think I've written about this, but I've been looking into something called Intermittent Fasting (IF) as a companion to Evolutionary Fitness (EV). What Art discusses in that first link is using IF as a normal part of fitness in order to achieve a more randomized energy intake and consumption pattern; not weight or fat loss, which is my primary interest for the time being. I've still got somewhere between 20 to 30 lbs. of fat to loose, and that's after already losing about 20.
I've conducted two 30-hr fasts so far, in both cases lunch being the final meal until dinner the following day, two hours after a strenuous weight-lifting workout. Interestingly, the toughest part of the fast was the first evening when my body was expecting dinner. The first fast, I actually went to bed early just in hopes of escaping the excruciating, almost nauseating hunger, which in itself ought to be a clue that your body needs a bit of whipping into shape. In both fasts I got to sleep quickly, slept wonderfully, and woke up refreshed and not hungry at all. The hunger returned mid-morning but was quite subdued and I found it no problem to put in a workout and then wait an additional hour or so before dinner. Over hundreds of thousands of years of evolution, it has only been the last 10,000 years where some people have had the opportunity to never be truly hungry. In short, we are designed to go significant periods of time without intake, and even to expend significant energy (like a hunt, a chase) prior to being able to eat. Wild animals exist in this fashion.
Here's a couple of things I can recommend to anyone interested in such an approach: The Fast-5 Diet and Eat Stop Eat. If you're the kind of person who has never had any problem with getting fatter as you get older, but are also the kind of person who doesn't usually eat 3-squares per day, well you just might have a clue into why that is for you, and perhaps reassurance that all the scolding you get from people isn't based in reality.
