i disagree. here is why
lower body temperature does not = lower body metabolism, in fact,
your body has to burn more energy, and work harder, to bring your
temperature back to normal
the same goes for high temperature, when your body is too hot,
energy is released to try and bring your body temperature back to
normal.
based on this logic, the time when your metabolism is lowest is
when you are feeling normal.
also, more food = higher metabolism.
there have been many arguments between doctors/scientists and etc.
one example is
when the body temperature is cold, it needs to work harder to bring
the body temperature back to normal, however, one way of
maintaining heat is not to lose body fat, so.. it might be a win
lose situation, with the increase of metabolism but decrease of fat
burning.
it is kinda hard to explain, but just know that to achieve the
optimum peak of metabolism without gaining a disadvantage of
something else is pretty hard to do, which is why it is best if you
experiment yourself. dont take it to the extremes though =D
