Lots of reasons I've seen. Some have injuries that aren't obvious. Some have no fun or satisfying outlet for physical activity. Some grew up socialized by their family and friends to eat poorly. Some are already in a deep rut mentally/physically and that's a self perpetuating condition. Some have too many responsibilities to their job and/or their loved ones. Some are addicted to their work.
I have been a few of these things at various points in my life. I am healthier now but I will not judge anyone for not being in great shape.
