The answer, Dr. Oz says, comes down to muscle. "Men tend to lose a little faster because they have more muscle mass," Oz says.
If Pam had more muscle, Dr. Oz says she would lose the weight faster. "Walking and lifting weights build up those core muscles and that's actually how you drop the weight quickly," Oz says. "The beauty of that is as the weight comes off, you can continue to eat and sometimes even eat more because the muscle consumes so many calories."
