Salma Hayek is using "industrial-size breast pump" to lose her baby weight, it has been claimed.

The 'Ugly Betty' actress gave birth to her first child Valentina Paloma last September.  Now she is resorting to extreme measures after friends told her breastfeeding is the best way to shed post-pregnancy pounds.

A friend of the actress said: "Salma has been pumping and freezing endless amounts of breast milk. When she's not feeding Valentina, she's hooked up to an industrial-size breast pump."

How awful.  Been there, done that. 

The friend added to Star magazine: "Whatever she does, she still can't drop the extra pounds."

Lactation expert Susan Condon has warned Salma not to push her body and try to lose weight too quickly: "After you have your baby, if what you eat is varied and well balanced, breastfeeding can help you lose your pregnancy weight without compromising either your health or your baby's by dieting. And you naturally burn calories to make breast milk every time you nurse."

"The best way of losing weight is to work toward a gradual weight loss, eat when you're hungry, and make sure you get enough fluids. It's the best way of losing weight easily and safely!"

Maybe Susan Condon should also let Hayek know that the more you pump, the more you produce.
