Fat cells explained. Fat cells are destroying your health

Fat cells are killing us because they cause diseases.
Did you know that fat cells send signals that promote blood vessel and cell growth, which could help explain why fat gain increases the risk of cancer. Obesity is linked to diabetes and cancer. We heard it in news so many times. But why is that? How fat cells are damaging our bodies?

An adult has between 40 and 120 billion fat cells, depends on the body structure.
In every fat cell we find one drop of oil that is used as energy storage for hunger times. What else can we find in fat cells? Anything else? There are hormones, inflammation substances and many more substances. Scientist identified about 100 different substances in fett cells. Many of them play a role with
inflammations (example: Zytokine) or with the regulatation of the blood pressure (Angiotensin II).
Why is this important?
Fat is the biggest endocrine organ in the body.
Many overweight people have large numbers of fat cells and those cells hold many substances. And many of those substances are harmful in higher concentration. They can cause inflammation in your body.
Fat cells are also an important control unit for many organs. Example: Fat cells are signaling muscles when they can burn fat.
Beyond that fat cells are important control units for many metabolic procedures in your body, they affect the function of the brain,
the liver, the pancreas and the immune system.
The fatty tissue plays a very important role as a hormone producer and controls long term fertility and energy balance.
Fat cells produce powerful substances called tumor necrosis factor-alpha (TNF-a), and interleukin-6 (IL-6), which help regulate the immune system.

An important hormone, which is formed in fat cells, is Leptin (discovered 10 years ago).
If leptin levels are high in your blood, it signals a saturation feeling to the brain. If the levels of leptin sink, it signals hunger.
Many of the substances discovered in fat cells seem to play the role of messenger in your body, with whose assistance fat cells with other organs communicate.
When you are in a good shape and you have normal weight, it seems everything to works perfectly within your body so the fat cells can communicate with other organs.

But what happens when we are overweight?
Giant fat cells produce to many messenger substances and can overflow other body signals. Example what can happen: insulin does not work correctly any longer.

What happens with excessively increased fat cells?
It begins mass production of inflammation materials.
Obesity leads to chronic inflammation.
What else happens withing the body?
Fat cells cause insulin resistance.
Many of the inflammation materials from the fat cells are causing the insulin resistance to.
As you can see fat cells are a whole complex system. They are not just a passive organ! Not just that they look ugly, make us look ugly, they have ugly consequences for our health.
Especially is bad for your health to have a lot of fat around waist area.
Those fat cells around your abs are very activ. They produce
free fatty acids, inflammation materials and blood pressure increasing materials. So if you have a lot of fat around your belly, it is time to lose it. You can see what fat can do to your health. It can ruin it.
I hope that I did not scare you a lot. There is some good news: The production of the substances in fat cells can be reversed with the right diet and exercise. If fat cells become smaller and you lose them, than the production of the health dangerous substances is reduced.
And on the end I would like to add an opinion from a professor of genetics and metabolism at the Harvard School of Public Health:
"Many people think your brain controls your fat. We promote the idea that your fat controls your brain."
