How
Do Weight Loss Pills Work?
How
weight loss
pills work
depends very much on the
ingredients they contain.
While some have an appetite
suppressant effect, others
will accelerate the
metabolic rate or will
eliminate toxins that
promote weight gain.
However, diet pills are
preferred over herbs for
weight loss because they
contain extracts, have a
higher concentration, and
hence are more effective.
Appetite Suppressive Effect
Diet pills based on hoodia gordonii fall in this
category, even though there
is not much published
evidence to sustain this.
Keep in mind, though, that
there are many other plants
that are able to suppress
the sensation of hunger. The
active molecule found in the
purified extract of hoodia
gordonii is called P57, and
as it is passed to the
brain, it helps controlling
the appetite. As a result,
you will ingest less food,
and thus reduce the calorie
intake. Appetite
suppressants, in general,
work by increasing serotonin
and catecholamine levels.
These two chemicals control
mood and appetite.
Metabolic Rate Accelerators
Some diet pills are meant to improve metabolism and to
promote calorie burning.
Exercising while taking such
pills will help you to burn
calories even faster.
Consulting a health care provider before taking such
diet pills is mandatory, as
they tend to increase blood
pressure. If you have
hypertension, you can try
lowering the dosage or
taking another type of
dietary supplements.
Prevent Fat Absorption
Another role of diet pills is to block the absorption
of dietary fat. The active
ingredients of these pills
inhibit the enzyme lipase in
the gastrointestinal tract.
As fat is no longer
assimilated by the body, it
will be eliminated in stool.
However, these pills also
affect the absorption of fat
soluble
vitamins. In order to
avoid deficiencies, you are
recommended to take vitamin
supplements along with these
diet pills. More than that,
diet pills are not adequate
to everybody who is over
weight, and hence, you
should take them only if you
suffer from obesity.
Antioxidants and Weight Loss
Acai berry extract, a common ingredient found in many
diet pills nowadays, is rich
in antioxidants that fight
free radicals and help your
body to stay healthy.
Antioxidants prevent cell
oxidization and improve
energy levels. The latter is
particularly helpful if
stress is the main cause of
your weight gain. You also
need to pay attention while
taking diet pills based on
antioxidants. Vitamins C, E,
and A are all antioxidants,
but need to be administered
carefully. Vitamin C is
water soluble and does not
pose a threat to your
health, but vitamins A and E
are fat-soluble and lead to
toxicity if taken in high
amounts. More than that, it
has been proven that these
vitamins are particularly
effective if they come from
fruits and vegetables,
rather than from dietary
supplements.
Regardless of the type of diet pills that is used, you
are advised not to take them
for prolonged periods of
time. In addition, you
should rely on diet pills
that are approved by FDA, as
these do not contain hidden
ingredients and do not have
serious side effects. These
pills need to be correlated
with a healthy diet and
regular
exercise,
in order to obtain optimal
results.
