Weight Watchers reports earnings Thursday, and even if the numbers aren't good, there's one figure that should make investors in dieting hopeful: 582 million.
That's how many pounds Americans gained collectively in 2015. Through births, immigration and overeating, there has been the equivalent of 1,400 blue whales added to the human biomass of our country in just a year, pointing to the need for groups like Weight Watchers to get the country lean and mean again.
Figures from the U.S. Census Bureau and weight data collected by Gallup tell the story.
