See http://www.kbnj.com/wd.htm for information about the Warrior Diet.
I follow this approach, and I fast until dinner most days, usually
drinking only water although sometimes drinking tea or coffee, and once
in a while having a small amount of a healthy snack such as nuts. The
research about alternating cycles of over- and under-eating continues to
grow. A recent animal study, using one day of fasting alternated with
one day of completely unrestricted eating, showed improvements in both
leanness and gaining muscle mass.
It's worth mentioning that, until you get used to not eating for
relatively long periods of time, your body will just go into what some
people call "starvation mode" and you will burn fewer calories than you
usually do. It's quite possible not to lose much weight at all doing
what you suggest, and to find your weight right back to where you
started 48 hours after you start eating again.
