what is it? Fat
packed deep in the abdomen, in and around your internal organs. Women with
waists over 35 inches and men with waists over 40 inches are likely to have it.
(For people of Asian descent, risk rises with measurements over 31.5 inches for
women and 37.5 for men.) A large waist is dangerous even if your body weight is
within the " healthy" range for your height. To measure your waist, wrap
a tape measure snugly around your midsection at about belly-button height.
What causes it? Too many hamburgers, too much TV, and too much
of all those other activities that keep you sitting down, like working and
driving. In other words, a diet high in calories and a life devoid of exercise.
Chronic stress plays a role, too, especially for women, since the stress
hormone cortisol directs your body to store more fat in your abdomen.
1. A high-calorie diet, lack of exercise, and chronic stress
conspire to prompt your body to store dangerous fat around your liver,
pancreas, and other internal organs.
2. Intra-abdominal fat pumps free fatty acids and inflammatory
compounds into the portal vein, the "superhighway" that delivers blood
from your lower abdomen to the liver, pancreas, and other internal organs.
3. An influx of
free fatty acids causes your liver to produce more “bad” LDL cholesterol, less “good”
HDL cholesterol, more blood sugar, and less adiponectin, a hormone that regulates
the use of blood sugar and keeps appetite in check. The result: Your risk of heart
disease and diabetes rises.
4. The inflammatory
compounds secreted by fat cells encourage the growth of plaque inside artery
walls, boost blood pressure, and make blood more likely to clot - a recipe for
a heart attack. They also make cells resistant to insulin, which in turn
contributes to diseases from Alzheimer's to cancer.
why is it dangerous? Unlike the relatively harmless fat on
your buttocks, hips, thighs, and even just below your skin at your waist,
intra-abdominal fat churns out substances that raise your risk of diabetes,
high blood pressure, heart attack, stroke, colon cancer, and even memory
problems. These include inflammatory compounds that make blood stickier as well
as free fatty acids that prompt your liver to produce more blood sugar and LDL ("bad")
cholesterol.
