These have often been helpful to me in this area:
- Proper vitamins such as B and Magnesium
- Reduce or eliminate alcohol intake as this can act as an inhibitor
- Proper eating (smaller meals more frequently)
- Include short bursts of intense activity with lower intensity activity in your workouts several times a week
- Ensure you are not depriving your body of proper calories and a balanced diet
I found this interesting article relating to the affects of alcohol and metabolism.
"Drinking alcohol will give a negative
effect on the metabolism of the body
particularly to the aspect of fats
The amount of energy that fats can
give to your body through the process
of metabolism is limited by the
effects of alcohol that you take in
The ability of your body to bring on
lipid oxidation or the burning of fats
will be greatly hindered by even just
a small amount of alcohol. This was
the findings of researchers and as
published in the American Journal of
Further research on this matter
revealed that when alcohol passes
through the liver, acetate is formed.
And the body, instead of burning fats
for energy will burn the acetate
instead of fats.
The other bad effect of alcohol in the
body is that it prevents the proper
processing of vitamins and minerals
which are needed in the natural
function of metabolism.
This is because of the process by
which the liver converts alcohol to
acetate. During this stage, minerals
and vitamins that are supposed to be
processed by the liver will be over
shadowed by the system of
detoxification and would be wasted
through this process."
