Eat every 3-4 hours? why?
When I was at a yoga training camp (month long), we were given only 2 meals a day, at 10 am and 6 pm, with a snack (tea + one fruit, usually pineapple) at 1 pm. I felt <i>much</i> better there, than when I was eating the <i>regular</i> thrice a day, plus some snacks inbetween.
