Why Cla for Weight Loss
may Hurt your Health
Cla for weight loss - one of the newer buzzwords in natural weight loss vitamins. Its
touted to help with experimental cancers, building lean muscle mass and helping fat metabolism.
Sounds perfect, doesn't it?
The dairy people seem to think so. You see, cla is found naturally as a result of the action of
bacteria in a cow's stomach on linoleic acid. (cla can be made by other means too - but this
is how it occurs naturally as opposed to in a lab. Commercial preparations of cla for weightloss tend to use the
bacteria without the aid of the cow's stomach).
Actually, cla for weight loss might be a great product for cow's wanting lean meat ... especially
in the summer months with all that beach weather.
There is some scientific literature to support an anticarcinogenic effect in mice. This is considered due to the antioxidant effects. So I guess the bottom line
is - if you have mice and they need to diet, why not give 'em cla for weight loss!
The question remains - what about cla for weight loss in us humans?
A well respected source on healing fats, Udo Erasmus isn't so keen on cla. In fact, he does not recommend cla for weight loss.
Normal linoleic acid (cla for weight loss 'cousin') has what is called cis double bonds. This
looks like a kinked molecule \\_/. These fit the body perfectly, and are the means by which essential fatty acids
do all their good work. Change the chemical bond structure even slightly, and you prevent essential fatty acids
from doing their essential work.
But the cla in cla for weight loss has two trans double bonds. Trans double bonds also occur in
hydrogenated fats like margarine (You didn't really think margarine was good for you did you?). These are not
recommended for a healthy body because ...
Trans Fats like cla for weight loss Do Not Promote
Health
Trans fatty acids interfere with the body's normal processes
-
they increase cholesterol
-
they increase low density lipoproteins (LDL)
-------> both of these are associated with increased cardiovascular risk.
-
they decrease high density lipoprotein (HDL), which is beneficial to the body
-
they interfere with the liver's normal detoxification system
-------> the liver enzyme affected also metabolises carcinogens
-
they interfere with essential fatty acid function
-
they make platelets more sticky.
-------> Sticky platelets can increase clotting, and the risk of strokes and heart attacks.
-
they affect the cells' membrane. They make it difficult for some molecules to get in, and for others to
get out.
-------> This in turn can effect cell vitality, immunity and allergic reactions.
-
they interfere with pregnancy
-
they correlate with low birth weight in humans
-
they lower the quality of breast milk
-
they increase blood insulin in response to glucose
-
they decrease insulin response
-
they interfere with the production of prostaglandins, which affect muscle tone in the walls of our
arteries, amongst other, arterial related functions.
The Dutch government were so concerned with the effects of trans fatty acids on our bodies that
they banned the sale of margarines that contain trans-fatty acids. And they have the longest life expectancy
amongst industrialised nations. Coincidence? I wonder what they would say about cla for weightloss!
Interestingly, you'll see in some literature touting cla for weight loss and some cancers, the
point that it is more stable than linoleic acid. That is true. Unfortunately, it doesn't mean they are better used
by the body. It is good for manufacturers though, as stability means a longer shelf life and more cost effective
manufacturing techniques. Trans fats behave more like saturated fats, and we all know about saturated fats in
excess.
The good news is that you can get the same effect of fat conversion from the much healthier
essential fatty acids - taken in the right combination, and in sufficient amounts, than you would for cla for
weight loss.
Why essential fatty acids are good for you
(and why they help dieters better than cla for weight loss)
-
they increase metabolic rate in our body when present in levels above 12-15% of total calories. This is
what helps dieters, and why you don't need cla for weight loss. The increased metabolic rate burns more
fat and results in loss of excess weight.
-
used for hormone-like functions that affect many tissues in the body (they are the precursers of
prostaglandins)
-
constructs cell membranes
-
create electrical potentials for cellular activity
-
can be used for fuel for energy
-
attract and help transfer oxygen on a cellular level
-
used in nerve impulses, by the brain, the sense organs, adrenal glands, the testes
-
can buffer excess acid and excess base in our system. This relates to our body's ph balance. A typical
western diet often leads to a condition of excess acidity, which has been related to disease
conditions.
Cla for weight loss actually blocks a lot of these functions.

The Correct Ratio of Essential Fatty Acids beats cla when it comes
to weight loss
Sources of W3 (alpha linolenic) fatty acids: flax,hemp oil Suggested dosage (Erasmus): 2-9 g per
day
Sources Of W6 (linoleic) Fatty acids: sunflower,sesame, safflower, hemp oil Suggested Dosage
(Erasmus): 9-18 g per day
Ratio: about 3:1 (W6:W3)
Long term use of flax oil only will result in W6 deficiency
Carbohydrates, Weight Gain & The dangers of "No
Fat"
If the public uptake of cla for weight loss and other related issues has done one good thing, it
is to bring another side to bear on the "No Fat" mantra of many dieters. Basically, no fat is very bad for the
overall health of the body. We need certain types of fat - namely, the essential fatty acids. And they can even be
good like cla for weight loss. The whole story on cla for weight loss has shown the potential. An excess of
saturated fats is not ok (sorry - you knew that though!).
What is most insidious about the "No Fat" issue is that often foods labelled as "No Fat" are very high in sugar and
other carbohydrates. Aside for any implications about blood sugar levels, what many people fail to realise is that
the body turns excess carbohydrates INTO fat. Anything high in carbohydrates that tips the overall balance of your
daily intake into excess carbohydrates, will result in extra fat stored in your body.
When I write about excess carbohydrates, I am not talking about eliminating them. The body needs carbohydrates too.
You have to consider your activity levels (mental as well as physical), age etc to determine what is excess for
you. If all else fails, your bottom or stomach will surely tell you :-)
btw... starches are sugar molecules bonded together. They are carbohydrates.
A few things to remember:
-
When oils are heated or chemically processed, they lose their health effects. Buy quality oils from a
health food shop, or in supplement form, if you want the above benefits.
-
Take them in salad dressing, mixed with yoghurt and fruit, or in juices. Just don't cook them at all!
This is a heartening story on how Kirwan Cox beat the autoimmune disease dermatomyostitis with healthy oils.
I've seen on one website discussing cla for weight loss statements which link linoleic acid with
fats like margarine, corn oil, and safflower oil. It goes on to say that therefore linoleic consumption is
excessive, and that the consumption of beneficial fats like those found in fish oils and flax, have gone down in
our society.
A few intervening facts...
-
linoleic fatty acids are ESSENTIAL to our body's functioning. They are classed as ESSENTIAL FATTY
ACIDS.
-
margarine is a trans fat. See above. Enough said!
-
corn oil and safflower oil as produced by modern methods are also trans fats. So everything I've
written about how bad trans fats are to the body, applies to these oils. Unless they are labelled
unrefined, or mechanically pressed, they are partially hydrogenated and TRANS fats.
-
Across society, many people do not consume adequate amounts of linoleic fatty acids. They are not
consumed in excess.
-
Yes, beneficial fats such as the W3 fats contained in fish oils and flax are not consumed enough. But
we still need to consume sufficient W6 fats (non hydrogenated ones) like linoleic acid. Remember the
ratios!

Udo Erasmus, the author of Fats That Heal, Fats That Kill, is known as the "Fat Man"! He is
the pioneer of all the recent ground-breaking work on "trans-fats", N-3 or 'omega-3' fats and essential fatty
acids ("EFA's"). His website provides a thorough education on the Right Fat Diet as opposed to the popular and
deceiving "Low Fat Diets" that have created a nation of obese and unhealthy "heart-attacks-in-waiting". Udo's
