It doesn't matter how long you have been macrobiotic for, or if you are Herman Aihara, or Nattoman. Your question centered on lack of protein as a possible reason for
fatugue, exhaustion. It is not a lack of protein that causes these problems, but a lack of understanding how to apply yin/yang adjustments of foods to one's particular
set of physical/mental/spiritual make-up.
Macrobiotics is flexible and modifications are required for each person and each environmnet/season, etc. If understanding was
absolutely correct there would be no disease, so problem is NOT lack of protein but lack of proper understanding and application. Modifications need to be constantly made due to aging, environment,
inheritence, genetics, etc. Sorry if you don't agree with this assesment. WHat do you think the reason is for some long term macros being "lethargic."? Maybe your long practice of macrobiotics will help us to
understand why this probalems SOMETIMES occurs.

In peace, Roy
