When you’re seated, electrical activity in your muscles slows down — especially in the powerful muscles of the legs and lower body. This causes your body’s calorie-burning rate to drop to about one per minute. That’s just a third of the rate you’d reach while walking around. After just a day, inactivity lowers insulin effectiveness and increases your risk of Type 2 diabetes and obesity. One study of overall sitting time in US adults found that women who sat for more than 6 hours a day had a 40% higher death rate. Another study of television viewing time in Australia concluded that for each additional hour of television a person sat and watched per day their risk of dying rose by 11%. Prolonged sitting was also found to double the risk of diabetes and heart disease — a risk that wasn’t eliminated by regular exercise. Authors of the diabetes study said that the average American adult spends 50% to 70% of their day sitting.
How to fix this? If you have a desk job, get up and take a short, brisk walk every hour. Instead of always emailing, walk around your office to talk to coworkers. Take the stairs and use a restroom on a different floor. If you’re willing to make an investment, there are standing desks for sale (or just pile up books on your desk for a do-it-yourself fix) and even treadmill desks. After work, park a little farther from the store on those errands and enjoy the extra exercise. Rise, shine and start moving!
The United States Preventive Services Task Force (USPSTF) recently released “Hormone Therapy for the Primary Prevention of Chronic Conditions: A Systematic Review to Update the US Preventive Services Task Force Recommendations.”
There is also a special version for consumers.
The Task Force conclusions are consistent with the NAMS 2012 Hormone Therapy Position Statement, which is also accompanied by a patient handout.
An interesting component of this USPSTF publication is a section discussing the public comments that were made during the time the draft was posted online earlier in the year. The Task Force points out that it is not addressing the use of hormone therapy for treatment of menopausal symptoms. These features make the report very consistent with our HT Position Statement and allow room for our Experts Do Agree solidarity statement regarding treatment of menopausal symptoms, also with patient handout.
But not too much! The good news keeps on coming about the potential benefits of cocoa flavonols. They may improve your mood, cut through mind fog, and take your blood pressure down a few notches. One of the latest studies on these effects hinted that chocolate with medium and high levels of cocoa flavonols could improve visual attention and verbal skills in elderly people. Cocoa powder, rather than chocolate bars, may be the best way to get your flavonols with the least amount of calories. The short-term visual/verbal study also showed that the chocolate drinkers had decreased insulin resistance (a group of risk factors for diabetes and cardiovascular disease), blood pressure, and lipid peroxidation (which gauges cellular damage).
A recent dark chocolate/blood pressure study, which reviewed all of the reliable studies published, concluded that dark chocolate can bring down blood pressure a few points—2.8/2.2 mm Hg. Even a couple points helps reduce your cardiovascular risk. Overdoing it on chocolate bars can make you gain weight and wipe out the benefits. Just an ounce should do.
