What makes us fat? Well, contrary to popular belief it's not as
simple as too many calories. In fact, there are many factors that can cause us to gain
weight, and one of the major factors is the hormonal and physiological affect
certain foods and substances create when they enter our
bodies regardless of calorie content. Do they cause a spike in
insulin? Do they alter thyroid function? Do they alter gene expression? Do
they create a stress response? Do they make you feel lethargic? There are even
certain substances, when ingested that actually cause disruption in hormonal processes and
metabolism.
So what is a hormone? Well,
a hormone is simply a compound that is released into the blood that is designed
to interact with another organ, tissue, or cell; organs that secrete hormones
are called endocrine glands. Some examples of endocrine glands in the body are
the hypothalamus that helps to create the brain body connection, the thyroid
gland that helps to regulate metabolism, and the testes/ovaries that release
different sex hormones. Basically, hormone communication can be compared to
sending a letter to someone that instructs them to perform a certain
task.
Unfortunately, toxins are
everywhere, and when they enter our bodies they can wreak havoc on normal body
function. Within the scope of toxic chemicals, there is a class known as
Endocrine Disrupting Chemicals (EDCs). These toxins are found in our
environment, in our food, and products we use. These EDCs can specifically
interfere with hormone synthesis, hormone metabolism, and interfere with normal
hormone function by affecting the thyroid, neuro-endocrine glands, sex organs,
and insulin/glucose regulation. When this happens, the delicate balance
of hormones can be disrupted resulting in major issues.
Now obviously we are
talking about toxins in relation to weight gain, but these different EDCs
can cause many other problems such as cancer and infertility. Many of these
chemicals are found in different cosmetic products, pesticides, plastic
products, industrial solvents, and some petroleum based products. So basically,
in stuff that is around us 24/7, and that is why it is so important to try
to eliminate as many toxins as possible in your daily life. There is a more
extensive list at the end of this article.
There is also a class of
toxins that is closely related to EDCs called "obesogens", and just
like the name suggests, these toxins can be a factor in weight gain and
obesity. Obesogens are found in the foods we eat, in different pharmaceutical
drugs, and industrial compounds. These toxins can cause the number of fat cells
to increase, because the fat cells to increase in size, affect hormones that
control appetite and satiety, and affect overall metabolism. One of the
scariest effects of obeseogens is their potential to act on DNA without
actually changing the genetic code, not only causing the individual to be more
prone to obesity, but also passing the trait of obesity to their offspring. Just
like many toxins, obesogens can be found in synthetic products, pesticides,
pharmaceuticals, and industrial chemicals. Some notable obesogens are fructose,
MSG, nicotine, estradiol, and lead.
When we consume toxins, our
bodies have different mechanisms in place to help neutralize them and make them
able to be excreted via urine or stool. When we are exposed to too many toxins, they can travel around the
body, and since many are fat soluble they will embed themselves into different
fatty organs like your endocrine organs or brain. These toxins can remain there
for years causing that gland to function poorly. Over time, as more and more
toxins build up in the body, these different organs and glands begin to
malfunction more and more, and create the ideal conditions for hormone and
chemical imbalances to occur. These malfunctions can lead to many different
conditions and dysfunctions including weight gain.
The main function of fat
cells is to store fat to be used as energy at a later time. However, there is
some evidence that suggests our bodies use fat cells to store excess toxins
because so many toxin are fat soluble. So just as fat is important for energy,
it may also be important in keeping toxins out of other fatty organs such as
the brain. So if you are consuming or exposed to high levels of toxins, your
body may be more inclined to increase fat as a means of toxin storage as well.
Another way toxins can
affect you, when it comes to weight gain, is by affecting your mental status.
There is a link between depression, fatigue, and lethargy caused by toxins that
can be associated with excessive weight gain. If you think about it, eating
healthy, working out, and putting the necessary disciplines in your life to
live a healthy lifestyle takes a lot of motivation. Being exposed to different
toxins and chemicals, whether from the environment or diet, can cause people to
lack the motivation and energy necessary to accomplish what is needed to lose
weight. So without eliminating toxins from your diet or environment, it can be
extremely difficult mentally to overcome the obstacles that are preventing
weight-loss.
Hopefully at this point you
aren't freaking out, but have totally re-thought the "calorie in, calorie
out" model. So where do you go from here? Well, start eliminating toxins
from your life. Try to eat organic foods, wash produce well, drink filtered
water, use glass containers as much as possible, and avoid eating processed
foods. The truth of the matter is, we will never be able to avoid all toxins,
but our bodies have many very sophisticated mechanisms in place to eliminate
toxins. Plus, because of epigenetics, we know that gene expression has a lot to
do with the environment you place your body in. So by eliminating toxin
exposure, your body will actually be less likely to express genetic traits that
can lead to weight gain.
In the end, don't use this
as an excuse, because none of these factors override your free will, but it
does mean some people will have to work a bit harder than others to lose
weight. On the bright side, we all know people who overcame obesity, even
though they might be more predisposed to it than others, proving it is
possible.
Just like anything in the
body, it all comes down to expression. Are you exposing yourself to toxins
causing your body to express dysfunction, or are you trying eliminate as many
toxins as possible and providing your body with what it needs to help itself
detox and expressing health? A little can go along way when it comes to
eliminating toxins from your life. So if you are looking to lose weight,
instead of looking at the calorie content on the food label, try eating whole
foods, eat until you are full, and avoid processed foods and chemicals as much
as possible. I guarantee that if you do this, that you will not only lose
weight, but also see a transformation in your overall physical and mental
health as well!
