Why You Gain Back the Weight You Lost

Why You Gain Back the Weight You Lost
By Chris Chew

In most, if not all developed countries, obesity and the
chronic diseases caused by being overweight is a recognized and
stated health crisis. This condition is even declared as a
worldwide epidemic by the World Health Organization (WHO. If you
are overweight or obese, this article about the leptin hormone
will have a direct impact on you to lead a healthier and happier
life with much lower risks of weight related diseases.

Because of the huge negative health impact, loss of
productivity, rising medical costs and subsidies and for the
simple reason of aesthetics, huge amounts of research and
billions of dollars are being invested each year in the weight
loss industry to understand the obesity scourge and how to get
rid of it.

The energy balance and body weight regulation are complex
functions that are generally controlled by genetic disposition
and hormones. It is now known that our body weight is regulated
around a very narrow range of about 10 to 15 pounds on the
average.

This theory was developed because numerous research have
confirmed time and again that people who lost a significant
amount of weight usually returned to their starting point weight
over a period of time. For those of you who have successfully
lost weight before and gained it all back will not be surprised
with this finding. So how do we overcome this phenomenon?

You see, our body adapts to under or over eating by changing 3
basic metabolic functions. They are your resting metabolism
rate, metabolism during physical activities and metabolism from
the ingestion of food that you consume. So during weight loss,
your body's metabolic rate will slow down which in turn causing
lesser calories to be burnt off as energy. This will make it
more difficult for you to lose more weight and as such, you stay
within the boundaries of the weight range as metioned earlier.

There are many things which people do when undergoing a weight
loss program that upset their metabolism mechanism which is why,
most diets don't work! I bet you know that since you have
probably been on some kind of diets before. This is because the
diets are either too hard to maintain or if you have lost some
weight, you would have probably put them all back again. At
least for most people.

All is not gloom and doom if you are overweight because you can
actually tweak your body's own natural leptin production to lose
and maintain your weight permanently. Never heard of leptin
before? So what is leptin and why is it a weight loss hormone?

In the 1950s, scientists found a genetic defect in mice that
led to spiralling morbid obesity in a controlled experiment.
They found out that mice with this condition weighed up to 3
times that of the average mice and that they had a much more
ravenous appetite. Scientists further discovered that these
obese mice were deficient in a blood-borne protein that
regulated hunger and body weight. This protein was identified as
leptin in 1995 and its name is derived from the Greek word
"thin".

Leptin is now accepted as the main regulator of appetite and
metabolism in human beings. This hormone is mainly secreted from
our fatty tissues, although small amounts of leptin are also
produced in the stomach and the placenta.

Leptin binds to receptors that cause hormonal signals to be
released that can limit hunger and thus can control food
consumption. The greatest concentration of leptin receptors is
found in the hypothalamus part of the brain and this is the
reason why the hypothalamus plays a vital role in a person's
body weight regulation.

The leptin hormone has numerous effects on the body which
include:-

Hunger inhibition

Raise metabolism and thus burn more fat

Stimulates fat burning activities in the muscles and liver

Now, since most leptin is produced from fatty tissues, then
overweight and obese people will have more leptins, right? So
why are they still overweight?

You see, it is now known that consistently elevated leptin
levels impair the function of the leptin receptors, thereby
requiring greater leptin secretion to produce the same effect.
So production of more leptin to lose weight is not the answer to
fat loss but regulating its production is.

In other words, to lose weight with the help of leptin, you
must know when to eat, what to eat and how often to eat. Yes,
you can even consume food with chock full of carbs and calories
if eaten at the correct time and quantity which can actually
help you to produce leptin to lose weight!

You will also be glad to know that not only does the hormone
leptin has an impact on metabolism and hunger control, leptin
also plays important roles in your immunity system, lung
function, bone development and even reproduction.

So if you want to lose weight without gaining them back and
improve your health substantially, then find out more on how to
regulate your leptin production.
