Researchers from the University of Washington found that regular yoga practice is associated with mindful eating, an awareness of physical and emotional sensations associated with eating. By facilitating breath awareness, yoga practice allowed individuals studied to improve emotional regulation associated with food cravings. Yoga practice was associated with reduced body mass index and improved dietary habits.
