I've tried this a while back, and found it near impossible. The fasting days aren't too bad; hungry but with a lot of energy. The eating days however are killing; your breakfast is bound to be huge, after which you feel bloated and sluggish. The rest of the day I tried getting in sufficient amount of calories, which always failed, making you feel lazy and full all day. At the end, I usually managed to get in 130-140% of daily advised calories on the eating day, which starts taking it's toll after 5 or 6 rounds. This kind of diet also ignores non-eating related properties of a meal, i.e. a time to socialize, take a break or a it just being a routine activity. The day that I'm not eaten felt pretty weird, it's surprising how strong the habit of eating is.
