This does not bode well for us...
There's been quite a bit of research in recent years about the association between sedentary behavior (which includes time sitting, watching television, or using a computer) with serious health issues such as heart disease, diabetes, obesity and some cancers, according to the American College of Sports Medicine.
Now, a new study has found that being a couch potato on the weekends may be even worse for your weight than working at a desk all week.
"We know that, on average, people consume less or eat healthier diets on weekdays," explained study author Clemens Drenowatz to Healthday. "So, they may be able to get by with less activity on weekdays because their diet makes up for it. On weekends, they're eating more, which requires more activity or less sedentary behavior to offset."
For the study, Drenowatz and his colleagues measured a group of 332 adults, ages 20 to 35, and their inactivity over a ten-day period. The participants also reported their own sedentary behaviors for weekdays and the weekend. In addition, the study subjects had their body weight and body fat measurements taken every three months over a one-year period.
"From what we saw, the overall sedentary time wasn't that different on weekdays versus weekends," Drenowatz said. "A lot of people had sedentary occupations, like office jobs, and they didn't really make up for that on the weekends either. This suggests diet is the reason, though obviously more research needs to be done."
Drenowatz said that it was important to differentiate between actually exercising and just sitting less. Even a 20-minute reduction in couch potato time on Saturdays and Sundays can add up to a loss of more than two pounds and 1.6 percent of body fat after a year.
"I'm not telling people they need to go out and exercise — that's a separate issue — but just to reduce their sedentary time. It may be just standing up and walking around a bit can help, "Drenowatz said.
