New Exercise Findings

Exercise is an important part of a healthy lifestyle – especially after weight loss surgery. Exercise improves your mood and builds muscle, helping you to manage your weight postoperatively. However, just getting your daily dose of gym time may not be as beneficial as once thought.


Experts used to divide people into two categories – those who were physically active and those who were sedentary. Simply put, if you were getting daily exercise of 60 minutes, even if you were inactive the other 23 hours of the day, you were considered physically active and healthy. Exercising less than 10 minutes a day qualified you as sedentary – a designation carrying increased health risks such as hypertension, diabetes, and cancer. While it is often difficult to maintain a high level of physical activity in our western society where we are seated during school, work, or travel, these divisions of activity level still allowed many of us to be considered healthy if we just took a morning run and chased it down with a balanced breakfast.1


However, new studies are shedding light on just how insidious a sedentary lifestyle can be. In 2009, a landmark study conducted in Canada charted 17,000 participants’ activity levels and their risk of mortality. Researchers were not surprised to find that longer periods of sitting without interruption were associated with increased mortality. Shockingly, though, individuals who sat the most were about 50% more likely to die after the study than those who sat the least – even when controlling for age, smoking, and physical activity level – meaning that a morning run still won’t counteract a day of sitting when it comes to your health and well-being.2


These results can make it seem like staying healthy for weight loss surgery patients while meeting the demands of work, school or a family is impossible. However, the recent findings have allowed exercise experts to modify their definitions of “sedentary” and “active” individuals and their recommendations to each group.1 A few minor adjustments can quickly catapult you out of a sedentary lifestyle into a physically active one. Break up periods of sitting at work with errands that get you out of your seat such as walking while on the phone. Study for next week’s test by reading on a stationary bike. Make catching up with friends a time to investigate the neighborhood instead of hanging out on the couch. By making just a few minor adjustments to your daily routine, you can assure your health and effective weight loss surgery results for years to come.
