Body image is the way in which you see yourself physically and the thoughts and feelings that are brought on by how you see yourself. Many people struggle with body images because of the influence of the media especially on young women when media portrays the ideal body type and a "criteria" for what makes a person beautiful sends negative thoughts and perceptions of their bodies to women worldwide who don’t fit this criteria.
Stop comparing yourself to photo shopped images in magazines and on the internet it is an unrealistic representation of their body. Love those around you for who they are and not what they look like. Remind yourself of positives you see in yourself. Huffington post says "Re-evaluate self-worth: How we nourish our bodies has a lot to do with self-worth. Until you feel worthy of feeling your best, you will constantly undermine your own efforts to achieving that end."
