What is Metabolism and how can you boost it?
Your metabolism consists of a complicated set of cellular
activities that take place all the time. The way your body creates
and distributes hormones, rests and wakes and burns fuel, are all
parts of your metabolism. The virtue of exercise is that it
increases or boosts your metabolism by its effect on muscle cells
throughout the body. Metabolism is like money: the rich get richer,
and the poor stay impoverished. Men generally have a higher
metabolism than women: they also have a higher muscle-to-fat ratio.
However, there are always exceptions: a man who is out of shape and
doesn't get enough aerobic exercise will probably have more body
fat and a lower metabolism than a woman who is in shape.

People with higher muscle to fat ratios tend to have a
higher metabolism, which burns fuel more efficiently and prevents
excess fat storage. People who have more fat have a lower
metabolism that tends to conserve fat. While these facts have been
used to justify the argument that weight is largely determined by
genetics, the fact that metabolism can be increased by exercise and
diet means we do have some control over our bodies method of
storing and burning fats and carbohydrates. |
Five Common Metabolism Facts and Fallacies
1. Aging slows down the metabolism.
Technically this is not true. Reduction of lean body mass -
specifically muscle - causes the metabolism to slow down. People
tend to lose muscle mass as they age for one important reason -
they move around less. The more sedentary you are, the higher your
fat-to-muscle ratio becomes, and since fat doesn't need that much
energy to exist, your metabolism slows. If you keep eating the same
amount, your body stores the extra energy (calories) as fat,
perpetuating the problem.
|
The key to keeping your metabolism from decreasing from decade
to decade is to keep exercising, and make sure you include
resistance training to keep up your muscle mass. While this is a
simple answer, it is admittedly not always easy - you have to make
time for exercise, no matter how hectic your life is. The benefit
of doing this - in addition to enhanced metabolism - is that
exercise gives you more energy and reduces stress, making that
hectic life of yours seem more manageable.

2. Exercising in the morning will increase metabolism
throughout the day.
The truth is it doesn't make any difference what time of day you
choose to exercise - the important thing is that you do it. Thus
far, there hasn't been any research proving that exercise at a
certain time of day burns more calories than another. So why are
people often encouraged to work out in the morning? Research does
show that people who work out in the a.m. hours are more likely to
stick to their program than those who do their exercise later in
the day. Bottom line: the more often you exercise, the more
calories you burn, so pick a time of day, and days of the week that
work best for you. You want to be as consistent as possible with
your workouts so that doing them becomes second nature for you.
3. Eating Within 30 Minutes After Exercise is a Metabolism
Booster.
|
Sorry, but no. Post exercise meals make no difference in your
metabolism. However, that doesn't mean you shouldn't eat something
after you exercise. A small post-exercise meal or snack is great
for your glycogen levels, and helps your body recover from
exercise. So just because something doesn't do wonders for your
metabolism, don't dump it - it can still be doing you good in other
ways. |
4. Exercising Raises Your Metabolism for the Rest of the
Day
While this is true, the amount your metabolism raises is really
not all that much. Resistance training increases fat free mass
(FFM), which results in an increased metabolism, and studies show
aerobic training also raises metabolism even though it does not
significantly increase FFM. How much does this amount to? In the
case of resistance training, the increased FFM burns maybe 50 more
calories a day, and the raised metabolism from aerobic training
nets an extra 25 to 30 (this, of course, is not counting the
calories burned during the activities themselves).
|
Although these numbers may seem disappointing at first, keep in
mind that it doesn't take a lot of calories to make a big
difference over time. If 17 extra calories a day can add over a
pound a year, then 30 to 50 more calories burned will not only use
up that extra amount, but also create a deficit that will add up.
If you want to lose weight more quickly, however, you need to
create a larger energy deficit - burn three to five hundred more
calories than you consume daily, either by exercising more, eating
less, or both. |
5. I Shouldn't Eat After 8 p.m. If I Want to Lose
Weight
Technically, the time of day you eat makes no difference in your
weight loss program. The problem comes with what the average person
eats after 8 p.m., and how much. If you sit in front of the
television, scarfing down chips, before you know it you've consumed
several hundred calories - enough Kcals (energy) to power a
workout, when all you're going to do is head off to bed (and that's
doesn't mean that chips are a recommended workout fuel - you should
eat something with nutritional value!).

Actually, depending on how much you had for dinner, a small
mid-evening snack may be appropriate. The key word here is small,
and that's if your dinner was relatively light. Consider a snack
along the lines of lite cottage cheese, unsweetened yoghurt,
protein shake or an apple - if you're feeling hungry, that is (if
you're just bored or restless, give the snack a pass). Having an
evening snack will keep your internal engine stoked just a bit so
you won't wake up ravenous.
