Vow very interesting. I normally eat just two meals a day. Breakfast, and dinner, with the time between them being approximately 12 hours. Also, when I travel, I eat very less, which I normally do 4 or 5 times a year. While being abroad, I eat very less, just like the "fasting mimicking diet" you described. But if doing it once a month is very beneficial, I will try to do this each month.
