One of the primary problems of losing weight is the fact that all weight is not created equal. When you lose weight you will inevitably lose muscle mass as well. What if there was a way to tell you body to burn only fat?

Researchers at the Garvin Institute in Sydney, Australia, say they've created a new weight loss drug to do just that.

In mice, the drug has shown to be an effective tool in changing the signals to the brain that determine what fuel the body is to use for energy. By stopping certain signals, the body turns to fatty acids rather than protein. The result? The mice lost body weight while maintaining muscle mass.

This is the opposite of the way traditional weight loss drugs work. They work to alter the way the brain sends signals to the body in an effort to suppress appetite.

From ABC News, the head of the neuroscience program at the Garvan Institute, Professor Herbert Herzog, says these therapies tend to be ineffective.

"What we've found is that blocking one system that influences appetite and body weight regulation might not be enough to cause a significant change in reducing body weight," he said.

On his first day in Huntington, W. Va., Jamie Oliver spent the afternoon at Hillbilly Hot Dogs, pitching in to cook its signature 15-pound burger. That’s 10 pounds of meat, 5 pounds of custom-made bun, American cheese, tomatoes, onions, pickles, ketchup, mustard and mayo. Then he learned how to perfect the Home Wrecker, the eatery’s famous 15-inch, one-pound hot dog (boil first, then grill in butter). For the Home Wrecker Challenge, the dog gets 11 toppings, including chili sauce, jalapeños, liquid nacho cheese and coleslaw. Finish it in 12 minutes or less and you get a T-shirt.
So much for local color. Earlier that day, Oliver met with a pediatrician, James Bailes, and a pastor, Steve Willis. Bailes told him about an 8-year-old patient who was 80 pounds overweight and had developed Type 2 diabetes. If the child’s diet didn’t change, the doctor said, he wouldn’t live to see 30. Willis told Oliver that he visits patients in local hospitals several days a week and sees the effects of long-term obesity firsthand. Since he can’t write a prescription for their resulting illnesses, he said, all he can do is pray with them.
