Carbs high in Resistant Starch speed up your metabolism and your body’s other natural fat burners. As Resistant Starch moves though your digestive system, it releases fatty acids that encourage fat burning, especially in your belly.

These fatty acids help preserve muscle mass—and that stokes your metabolism, helping you lose weight faster. Researchers set out to fatten up two groups of rats, feeding one group food that was low in Resistant Starch.

A second group was fed Resistant Starch-packed food. The rats fed the low Resistant Starch chow gained fat while losing muscle mass. Rats that ate the high Resistant Starch meals preserved their muscle mass, keeping their metabolism moving.
