I'd argue - yes. Too busy to properly prepare food, leads to convenient food, which is seldom a good choice from a weight point of view. Too busy to take time to walk somewhere, drive-through everything sparing you even the smallest amount of physical effort - not ideal... Too busy to go to the gym during the normal day (hence admiration for the early riser who's at the gym at 4am,so they can do a workout before hitting the office at 6). Too busy to have mental downtime, peace, reflection, solitude. Leads to mental-health issues, which has a high correlation with inactivity and hence obesity. So yes, I'd suggest that "being busy" is a mindset that prioritises "productivity" and not things like wellness, or good eating. So tangentially, yes, I'd argue busyness leads to obesity via some indirection.
