It is an issue. I've worked in HR Management and Recruiting for most of my career. There are credible studies indicating overweight people earn less than their "fit" counterparts. I remember one high tech firm where my boss, the VP of HR had a "no slugs" policy - meaning overweight people. Needless to say, I didn't get converted from contract to full time... While I love my current job, I know that I'm less inclined to interview for a new, better paying position b/c of my weight and how it affects my self confidence.
