Yoga develops inner awareness. It focuses your attention on your body's abilities at the present moment. It helps develop breath and strength of mind and body. It's not about physical appearance.
Yoga studios typically don't have mirrors. This is so people can focus their awareness inward rather than how a pose — or the people around them — looks. Surveys have found that those who practiced yoga were more aware of their bodies than people who didn't practice yoga. They were also more satisfied with and less critical of their bodies. For these reasons, yoga has become an integral part in the treatment of eating disorders and programs that promote positive body image and self-esteem. -- Harvard Health Publishing
Mindfulness refers to focusing your attention on what you are experiencing in the present moment without judging yourself.
Practicing yoga has been shown to increase mindfulness not just in class, but in other areas of a person's life.
Researchers describe mindful eating as a nonjudgmental awareness of the physical and emotional sensations associated with eating.
