(PRWEB) May 9, 2005 -- Another major diet fallacy exposed: Eating protein and
carbs before exercising may lead to fat-gain and muscle wasting warns Warrior
Diet author Ori Hofmekler.
Pound down a good protein shake with some
banana before exercising to gain muscle lose body fat? According to
groundbreaking research, eating before exercising can be a recipe for disaster,
stimulating fat gain and leading to catabolic muscle loss — rather than the
opposite — warns cutting-edge diet guru and bestselling Warrior Diet author Ori
Hofmekler. http://www.dragondoor.com/b17.html
“Many people assume
that the human body operates like a machine and therefore in order to work, it
needs to be fueled liked a machine. Eating before exercise seems to make sense.
But does it really? “ asks Warrior Diet author, Ori Hofmekler and provides this
answer:
As you’ll soon realize, the idea that pre-exercise meals provide
the muscle with instant energy is literally wrong, often misleading and counter
effective.
In order to provide the muscle with nutrients and energy, food
must be first fully digested. During digestion food is broken down into smaller
compounds, yielding molecules of amino acids, fatty acids and glucose — which
are transferred to the body’s tissues through the circulatory system. The
digestion elimination process, that occurs in the stomach, intestines, liver and
kidneys, respectively, requires substantial amounts of energy. During digestion,
blood flow shifts from the brain and muscles to the inside organs (responsible
for digestion and elimination). That shift in the blood flow profoundly affects
the brain and muscle tissues, lowing their capacity to perform and resist
fatigue.
The question remains: “What about meals that require almost no
digestion?” such as those made from fast assimilating nutrients. (Note that fat
is a slow digested and assimilated nutrient compared to protein and carbs.)
Consuming a pre-exercise meal made from a blend of fast releasing
proteins and carbs (such as whey and sugar), looks initially quite appealing. In
theory such meals would nourish the muscle tissues with amino acids and glucose
to inhibit muscle breakdown, while providing instant energy. It all makes sense,
but even so, in real life, things often work differently than in theory.
Recent studies demonstrated that eating fast releasing foods before or
during exercise could be counter effective, to say the least. Investigators in
the school of sport and exercise science, University of Birmingham, Edgbastion,
England found that ingestion of carbs before exercise adversely elevated plasma
cortisol levels. Interestingly enough, there was a significant reduction in post
exercise cortisol when carbs were not ingested before exercise. Furthermore,
there was a faster shift from carb to fat fueling during exercise, when a
pre-exercise meal was not applied.
As for protein, what failed to reach
mainstream nutrition knowledge is the already established fact that protein rich
foods raise cortisol levels if applied incorrectly. Studies at the University of
Lubeck, in Germany, found that oral administration of fast releasing protein
foods such as hydrolyzed (pre-digested) proteins, have an even more profound
cortisol elevating effect, compared to whole protein foods.
Note that
chronic elevated cortisol has been associated with muscle wasting and fat gain
(in particular abdominal fat.)
In summary, pre-exercise meals may rob
the brain and muscle of energy (due to digestion). Eliminating the digestion
effect of pre-exercise meals may only make things worse. Eating meals made from
fast releasing proteins and cabs, before exercise, can cause a profound cortisol
elevating effect during and after exercise. This may severely compromise ones
ability to build muscle and burn fat.
In conclusion, DO NOT EAT before
exercise, instead eat right after exercise.
Ironically, the same meal
that would be counter-effective before exercise can be most effective and
beneficial when applied after exercise.
Numerous studies have
demonstrated the critical positive effects of post-exercise recovery meals on
total muscle recuperation (i.e. replenishment of energy reserves and increased
protein synthesis). Recent studies at the University of Texas Medical Branch, in
Galveston, TX, revealed that applying fast releasing proteins and carbs after
exercise had substantial anabolic effect on stimulating net muscle protein
synthesis, even in cases of elevated cortisol.
Consequently, we are not
preprogrammed to be fueled like machines. Our biological machine is based on
survival mechanisms that when triggered, increase our capacity to utilize fuel,
generate energy and better survive.
We trigger these mechanisms, when we
follow cycles that rotate between undereating while in an action followed by
eating while in rest.
For the human body, timing affects everything. “It
is when you eat that makes what you eat matter.”
If you insist on eating
before exercising then there are some crucial things you should do to avoid
