Hardly anyone is driving a truck from coast to coast 6-10+ nights away from home anymore. It doesn't work that way anymore. At most, most independent drivers or drivers who work for smaller companies are staying away from home 1-3 nights a week/6-10 nights a month. Most truck drivers doing long haul don't eat out. They have meals more or less prepared and take with them. I see a lot of cube farmers eating out almost every meal more than truck drivers.
As far as sedentary, please explain what this is:
Wake up, shower, dress, take blood pressure meds, get in small car, drive to Startbucks, get large cup of caffeine. Continue driving in small car for 30-50 minutes to office building. Get to cubicle in building, then refill cup with more caffeine, grab donut or such, sit down at cubicle, star at 2-3 computer monitors when not slunched over looking at phone. Text on phone screen for 20 minutes out of 60, type on keyboard 10 minutes out of 60, move mouse 25 minutes out 60. Repeat for 2-3 hours. Get up, go to bathroom, stop by caffeine machine again, chit-chat with other drones, go back to desk and repeat the above. Lunchtime. Order something to be delivered to your office door. Eat that over the next 90 minutes while sitting, staring at screens, typing on phone. Continue the above for 4 hours.
Get back in car, maybe grab a Monster/Red Bull/etc on the way home or to the brewery. Sit at bar stool while sipping on the new cool IPA while scrolling on phone. See that it's 8:00 pm, leave, grab some food at a drive-through on the way home.
