In the before ones- people are generally dressed baggily/frumpily, wearing little/no make-up with their hair fairly neglected. They are posed with their hands across their bodies, or behind 'props' (furniture/people etc.). In the after ones- people are groomed beautifully- dressed in fitted clothes, their make-up/hair done, and with their hands on their hips! It's amazing what losing weight has done for their self-confidence. That alone should be a motivating lesson!
