Fat ---It's Alive!
Fat, it seems, is alive.
Fat is an active substance emitting a number if hormones throughout
the body. Where fat gathers around the middle of our
bodies,---becoming a smothering blanket around our vital organs--- it
can be especially harmful, sending out streams of proteins called
cytokines. These substances are secreted by fat and can produce
harmful inflammation, setting the stage for heart disease, arterial
damage, stroke and cancer.
While the exact mechanisms are still being studied, what we know so
far is that high levels of fat increase insulin resistance, a condition
which may increase your risk for developing cancer , diabetes and
heart disease. Also, fat increases the production of estrogen which
may raise your risk of developing hormone-related cancers such as
breast and uterine cancer.
Waistline fat includes not only fat directly under the skin, but also the
visceral fat nestled around vital organs. Scientists say the latter type
of fat is most strongly implicated in the aforementioned metabolic
disturbances.
Remember when the „perfect” measurements of a woman were
38-24-38? A 24-inch waistline --or something reasonably close--
may have been discarded as a canard of a sexist past but new studies
may make us all have to take a second look at the usefulness of the
measurement.
It turns out that your waistline measurement may tell us more about
your overall health than any other statistic. Why? All fat is not
created equal. And fat around the middle may be the worst fat of all.
Your waist line measurement may be the most important indicator of
your overall health. It may indicate your risk for developing heart
disease, stroke and diabetes.
In contrast to the popular notion of fat as an inert blob, fat is actually
an active substance. Fat leaks a constant stream of hormones into
your bloodstream and some of these hormones are quite harmful.
In 2006, Canadian scientists in Canada studied the waist sizes of
168,000 men and women worldwide.
The results were, well, heart-stopping. The study showed that the
risk of heart disease increased 21 to 40 per cent for every 5½in
(14cm) a man added to his waist line. In women, the risk of heart
disease increased 21 to 40 percent for every 5¾in (14.9cm) increase
in their waistlines.

Visceral fat is different from other body fat. Visceral fat, also called intra-abdominal fat, refers to the fat that surrounds the internal organs. Subcutaneous fat, on the other hand, is body fat that is close to the skin's surface and is considered less dangerous, and easier to loše, than visceral fat.
Studies have shown that those with visceral fat are more susceptible to heart disease, stroke, diabetes and hypertension. Sedentary people, smokers and drinkers have been shown to have more intra-abdominal fat, or visceral fat, than active people who are non-smokers and non-drinkers. Stress may also be a factor in the storage of visceral fat on the body.
Visceral fat is harder to loše than subcutaneous fat because it is more deeply embedded in the body's tissues. Visceral fat is only measured accurately by an imaging machine that can see how much of the abdomen is made up of visceral fat. A person may be within a healthy weight range, but still have too much intra-abdominal fat around the internal organs.
The liver metabolizes visceral fat and releases it into the bloodstream as cholesterol. Harmful, or „bad” cholesterol, which is Low-Density Lipoprotein (LDL), builds up into a plaque that blocks the arteries. Losing weight through proper diet and effective exercise can help reduce visceral fat. How much fat a person eats does matter as studies have shown that those who eat 30% or more of their diets as fat usually have high amounts of visceral fat.

Fette
Fett in der Kunst
Des Weiteren war Fett ein vom Künstler Joseph Beuys häufiger eingesetztes Material, um innerhalb eines künstlerischen Objektes oder einer Rauminstallation gespeicherte Energie zu symbolisieren. Bekannteste Objekte: die „Fettecke” und der „Fettstuhl”.
Fettabscheider
Typischerweise werden Fettabscheider in Metzgereien, Schlachthöfen, Frittier- und Großküchen eingesetzt. Sie werden immer dann eingesetzt, wenn Fette und Öle organischen Ursprungs aus dem Schmutzwasser zurückgehalten werden sollen. Über eine integrierte Prallplatte wird das Schmutzwasser in den Fettabscheider geführt, was zu einer Verringerung der Strömungsgeschwindigkeit und einer gleichförmigen Strömungsverteilung führt. Die Trennung der abscheidbaren Leichtstoffe (Fett) und Sinkstoffe (Schlamm) von Schmutzwasser wird alleine durch die Wirkung der Schwerkraft erreicht. Mit einem Koaleszenzabscheider können auch feiner verteilte Öle und Fette abgeschieden werden.
