Is Your Fat Toxic?

Like the old Britney song, is your fat toxic?

Toxic fat cells may help explain why most obese people develop heart disease and diabetes, while a few are fat but fit.

Researchers at the University of California-Davis took fat tissue from the rear ends of 70 volunteers. Some participants were obese but otherwise healthy. Others weren’t necessarily obese but had metabolic syndrome—a cluster of health problems, including obesity, high blood pressure and abnormal cholesterol levels, which double your risk of heart disease.

The fat cells of people with metabolic syndrome had higher levels of 11 different molecules linked to diabetes and cardiovascular disease, including the hunger-regulating hormone leptin and artery-inflaming C-reactive protein.

Fat tissue from people with the metabolic syndrome also had three to five times as many macrophages, immune-system cells that gobble up cellular waste. Sound like a good thing? Not quite. They kick off a harmful process by telling the body to produce more of a protein called MCP1, which can cause inflammation and heart disease.

“Before, researchers only measured these things in the bloodstream,” says lead author Ishwarlal Jialal, M.D., Ph.D. “We went straight to the fat cells and showed that they produce a lot of the substances that can increase the risk of both diabetes and heart disease.”

Researchers don’t yet know why some people’s fat cells release more of these substances. Genetic mutations might contribute. Some studies have shown that genes linked to the way your body stores fat and uses insulin contribute to metabolic syndrome. But in many cases, the same types of lifestyle factors that contribute to obesity—a poor diet and lack of exercise—may eventually turn fat cells toxic, Dr. Jialal says.

Only about 20 percent of obese people—most of them postmenopausal women—seem to be protected from metabolic syndrome, Dr. Jialal says. For the rest of us, if you’re obese, you can prevent or even reverse metabolic syndrome by losing just 10 percent of your body weight.

Hi, thanks for stopping by at my website. This is my journey to achieve 202 pounds of lean body mass and 15% Body Fat. Let me explain. Weighing yourself with traditional scales is very important, but you also need to measure your body fat as well. You could go to the gym and weigh yourself before and after a long run. The second weigh in, you may well have lost two pounds – that is water from sweat, not body fat. So, my goal is to be 202 pounds LBM and 36 pounds of fat – a total of 238 pounds. When i’m there, my goal is to be 202 pounds LBM and 22 pounds of fat – a total of 224 pounds. This blog will chart my progress.
