Health Roundup: Obesity consequences, belly fat and 'magic' pills

40 percent of US cancers linked to excess weight

The findings by the US Centers for Disease Control and Prevention "are a cause for concern," said the agency's director Brenda Fitzgerald....Carrying excess weight has been shown to boost the risk of 13 types of tumors, including cancers of the esophagus, thyroid, postmenopausal breast, gallbladder, stomach, liver, pancreas, kidney, ovaries, uterus, colon and rectum.

Being overweight makes your heart larger and heavier

Researchers at Queen Mary University of London and the University of Oxford examined MRI scans for 4,561 people from the UK Biobank database.  They found an increase of 4.3 in BMI, which could take someone from a healthy weight to the brink of obesity, made their heart substantially heavier, raising the risk of suffering a heart attack or stroke.  A bigger, heavier heart raises the risk of conditions from an irregular heartbeat to a heart attack, and the organ should in fact grow smaller with age. A larger heart stretches its upper chambers, disrupting the electrical signal needed to keep it beating regularly.

Experts Raise Red Flag over Fatty Liver Disease

An increasing epidemic of fatty liver disease in the U.S. is likely to ruin the health of millions and cost billions of dollars a year, experts said here. Some 65 million Americans have non-alcoholic fatty liver disease (NAFLD) and that number will reach 100 million by 2030,.  Rising rates of obesity are the force behind the epidemic of NAFLD, an umbrella term covering a spectrum that begins with accumulation of fat in the liver, followed by ballooning, scarring, cirrhosis, and eventually liver failure, cancer, and death.

Yale University researchers have found that belly fat is linked to inflammation

They discovered a new type of macrophage that resides on the nerves in belly fat, which becomes inflamed with age. These inflamed cells do not allow signals to be sent to fat cells telling them to burn their stored energy. The report's researchers concluded that drugs that target this inflammation could spike their metabolism and help them burn more fat, which decreases their risk of chronic illnesses.  Study author Christina Camell said: 'The purpose of our research is to achieve greater understanding of immune cell interactions with nerves and fat cells to potentially reduce belly fat, enhance metabolism and improve performance in the elderly.'

This Needle-Covered Patch Dissolves Excess Body Fat Wherever You Stick It

Developed by researchers at Columbia University and the University of North Carolina, the medicated patch uses an array of skin-piercing microneedles to deliver nanoparticles of drugs to the body, and while it hasn't yet been tested on humans, trials with mice show it reduces fat by as much as 20 percent in treated areas by converting energy-storing white fat into energy-burning brown fat.

Is this exercise pill the real deal?

Biologist claims he has found the only formula to burn fat and grow muscle with one tablet.  Ronald Evans developed a drug to stimulate what the body feels during aerobic endurance. The chemical PPARD is released during aerobic exercise. Sedentary mice were injected with the chemical and 70 percent experienced a decrease in fat and an increase in stamina. Athletes have previously abused earlier forms of this drug to boost their endurance levels

Too much exercise can kill you - especially if you're a white man

Researchers in Chicago assessed exercise patterns over the course of 25 years. They found that very active white men are 86 percent more likely to experience a buildup of plaque in the heart arteries by middle age. This was not the case in black men, based on 3,175 participants. They found that  7.5 hours a week of fitness DOUBLES your risk of heart disease.
