In a headline that won't be a surprise to your newly-notched belt after Thanksgiving, people gain an average of six pounds during the holiday season.

The overwhelming reason, according to a survey of 2,000 adults that was commissioned by Herbalife Nutrition, is that many people have sworn off eating healthily until they kick in their New Year's resolutions.

With 45% of those polled noting they're going hog wild until January 1st, it's no surprise that 71% of those polled say they swear to eat better and exercise more in 2019. More than half -- 55% -- say they're focusing on "self care."

As for 2018, just 12% will survive the holidays without gaining any weight, the poll explains.
