[quote=spdrun]Long, sedentary periods of work sure don’t help. Jobs with long working hours in the past tended to be blue-collar and involved physical exertion.

Nor does lack of free time to cook, or grab anything other than fast food for lunch.

Of course, there might be other factors in play, like obesogenic chemicals in food and the environment.[/quote]
It still mostly comes from calories dense nutrition light eating and drinking and too little energy spent during the average day.

Most people can do an amazing job of losing weight if they tried ,but don’t keep it off. So I don’t think there is too much voodoo fat out there. My MIL a big desert eater always says her son got the fat tendency from her, until he got serious about his health and is now 6’3″ 170 something.
Office people can get desks for standing work, and I think there is even one that lifts and lowers so a person can stand or sit at it( sit when you need a break from standing. Some engineering offices I have seen have high tables with tall backless barstools and people do tend to stand as much or more as sit. Sitting on a exercise ball instead of a chair keeps muscles engaged. 10 pull ups 10 squats and 10 push up and hour in a 12 hour day wouldn’t hurt work productivity too much , if it didn’t actually increase it. 120 pull ups , body weight squats and push ups is a pretty good workout especially compared. Add , a half hour jog or an hour walk most days and you are set.

It’s funny how many people find out that I exercise and eat pretty well and they say ” wow , why do you do that? You never had a weight problem”.
