From this BBC article Lifting weights 'good as running':
“Weight training could be as effective as endurance exercises like running when it comes to burning fat and warding off diabetes, a study suggests”.
"We've shown that Type II muscle does more than allow you to pick up heavy objects," said Kenneth Walsh. "It's also important in controlling whole-body metabolism."
"If you have these muscles, even when you are not doing much, you are still burning up energy”.
