The average American walks around 2.5 miles a day -- with about 2,000 to 2,500 steps per mile, depending on the length of the stride.

Green juice drinks are the toast of social media sites where influencers extol the latest nutrition fads. These beverages are often made from celery, kale, chard, spinach, wheatgrass, parsley, dill and mint, and sometimes with whey protein -- then sweetened with fruits or added sugar.

More than a third of Americans report they're socially isolated or lonely and 10% say they rarely feel there's anyone they can turn to for emotional and social support.

I'm a great fan of walking 10,000 steps a day -- or the equivalent. But what exactly is equivalent? And how does that get figured out?

Well, the conversion of steps into other activities is based on the estimated effort, called a Metabolic Equivalent for Task or MET, that it takes for each activity. And while it's been determined based on solid...Read more

These days, 60% of Americans say they're obsessed with making sure they get "enough" protein, when, in fact, many get a healthy dose or even exceed recommended levels.
