INTRODUCTION
Calorad stormed onto the scene around the mid to late 1990s with
claims that you can lose weight while you sleep. This
product claims to improve a multitude of ills. The magic that seems
of particular interest to the athlete are the claims that this product
will enable one to lose fat and increase muscle mass without any
real effort. We want to believe, but are we really that gullible?
Are there any facts behind the product claims? Lets start
out with a closer look at the mystery ingredients found in Calorad.
MYSTERY INGREDIENTS?
Truth be known, there is nothing whatsoever mystical or magical
about Calorad other than it is an expensive protein supplement.
A breakdown of the ingredient list reveals:
Collagen HydrolysateSimply hydrolyzed
collagen which is nothing more than degraded protein (collagen is
a bodily protein). Why not eat an egg or a slice of chicken, or
a can of tuna for $1.39?
Aloe Verahas a laxative effect
when ingested orally and can cause gastrointestinal upset in some
individuals. I guess frequent trips to the bathroom could theoretically
cause weight loss.
Glycerinchemically, it is a sugar
alcohol (1,2,3 propanetriol). It is probably used as a mild sweetener,
as many users have mentioned Calorad’s off-taste.
Potassium Sorbate & Methyl ParabenNothing
more than preservatives to keep the collagen from spoiling.
Natural Flavor, Demineralised WaterJust
a couple of extras for flavor and volume, but would hardly have
any effect in the body.
This, in fact, doesnt appear
to have any thing to do with magic. All of these nutrients can easily
be found in food that we all eat on a daily basis.
WEIGHT LOSS
It is probable that the said weight-loss associated with Calorad
stems from the fact that its users don’t eat anything before bed,
three hours to be exact. Then the consumer is supposed to take the
Calorad on an empty stomach right before going to sleep. Low and
behold, watch the pounds not-so-miraculously melt away.
Enter critical thinking here: Let’s
say Mary Q. Public was formerly eating 2500 calories per day, and
hypothetically, 500 of those calories were regularly consumed within
three hours before bed. So now she’s replacing those 500 calories
with 14 calories worth of Calorad, for a deficit of 486 calories
per day.
Considering about 3500 calories per
pound of fat, we estimate that 486 calories (round up to 500 for
simplicity purposes) multiplied by 7 days per week equals 3500 calories
extra that are not being consumed. This alone would constitute a
pound of fat per week. Add in exercise and the caloric deficit would
be larger, consequently leading to greater weight loss. No magic
here, just elementary arithmetic.
If we eat less that what we need for
energy we lose weight. We certainly dont need to spend extra
money on Calorad to eat less. Well we still have another claim.
Calorads promoters tell us to believe that this product will
cause us to magically increase our muscle mass. Is there any truth
to this claim?
LEAN BODY MASS INCREASES?
Believe it or not the claims still persist that Calorad will actually
generate muscle in the body, or, I think the terminology used was
that it can cause an increase in lean body mass. Irrespective of
what is claimed, muscle does not just spontaneously generate based
on the consumption of a protein supplement. To take this one step
further, you could inject yourself with anabolic steroids (not that
I advocate that) and not gain an ounce of muscle unless you provide
additional demands on the body’s musculature via resistance training.
Its quite unlikely that hydrolyzed collagen certainly would
cause an increase in lean body mass.
Ceding the benefit of the doubt, consuming
protein while lowering calories can help attenuate the loss in muscle
tissue associated with its breakdown for use in gluconeogenesis
(forming glucose from not carbohydrate sources). But even so, this
would not cause an increase in lean body mass. In this case, the
burden of proof is on the company to provide legitimate evidence
that it can, in fact, INCREASE lean body mass, and consequently
the metabolic rate.
To those selling Calorad, if this proof
exists please provide it for all to see. If you are convinced that
it can increase lean body mass, explain how you quantify this increase.
What tests have you done to prove that Calorad does indeed increase
the amount of muscle? These are honest questions that deserve an
answer. Is this not a claim made by Calorad and its force of distributors?
THE RESEARCH
There is no formal research on Calorad that can be found in peer-reviewed
journals. Why? Simply because it does not exist. Anecdotal testimonials
considered to be testing or proof of efficacy are completely
unscientific and hold no merit except for those that sell the product.
And, separating cause and effect from coincidence is difficult outside
of experimentally controlled conditions, so making definitive statements
as to its effectiveness is inappropriate.
