Among the most popular resolutions people make are eating healthy and getting into shape.
We found that both of those actually have a pretty big impact on valley businesses.
Welcome Chicken and Donuts on 15th Street and Buckeye sells what most people consider to be a delicious array of fried confections
"We work with a lot of classic flavors that we put a spin on," said Evianna Parra, General Manager at Welcome Chicken and Donuts.
Maple bacon, red wine glaze, despite these delicious sounding flavors, business hasn't been as sweet as it could be.
"The first week after the new year we kind of just drop down," said Parra.
Parra says it happens every year like clock work, people stop eating donuts because of New year resolutions to get healthy or lose weight.
"We even had people coming in in groups. One person would get donuts and everyone else would be like, 'No, I'm on a diet'," said Parra.
You'll find the exact opposite at gyms and health clubs like The Village on Camelback and 44th Street, where things really pick up as a result of those same resolutions.
"People do tend to make New Year's resolutions about either getting back in shape or maybe losing a little bit of weight," said John Smallfield. "The number one resolution people make, to lose weight, which is why."
Smallfield sees more new members at The Village around the holidays as well as an increased commitment from those who slacked on using existing memberships.
"It's never too late to start and there's lots of activities you can start at any age, whether you're 65 or 25 or a young kid," said Smallfield.
Studies show 75 percent of resolutions are maintained during the first week of the year. That drops to 71 percent in the second week, to 64 percent in the first month and 46 percent in the first six months.
Those stats might actually be good news for places like Welcome Chicken and Donuts.
"It picked up yesterday actually. I think it helps people going back to work people done feeling very full from New Year," said Parra.
