I run a start up pharmaceutical company that is developing a weight loss medication. I am interested in a logo for the company. Imagine a smudge of charcoal that has been smeared left to right. I would like to duplicate that same left (darker) to right (lighter) fade. I would like the logo to show a straight on view of a silhouette of an obese man that then degrades into a man of normal weight. I would like each of the transformations to overlap a bit and for each transformation to flow as he sheds weight while illustrating both movement and health. I am not sure about the color, perhaps back and white would be the most powerful. These are just my preliminary ideas and am open to suggestions.
