Mirror mirror on the wall: new technology is giving researchers a unique way to look at us all.

3D body scanning could be the next big thing in the health and fitness industry.

"We can scan your body, determine where the fat and lean is,” John Shepherd, UH Cancer Center said.

And more, simple household scales: move over. 

"Mainly because the scale only gives you weight, it doesn't tell you how much of your weight is muscle or fat,” Shepherd said.

This technology provides real-time data about a users body.

Shoulders, arms, even waist.

Step on the scale, step off to your own Avatar.

Here's how it works. For a male, you can be in tight biking shorts or your underwear that are not patterned.

The spin and scan take about 20 seconds. The device then loads your data to an app on your phone.

Its makers expect their product to hit the market sometime in 2018.

"For exercise and fitness, it’s going to be huge, just to be able to objectively measure those changes and when you make a change you don’t know how it actually affects you, you’re not really inclined to stay on the wagon so that will help,” Sam Winter, Naked Labs said.

The 3D scanners are also helping the University of Hawaii Cancer Center. It's a new study called Shape Up is just Starting up.

Researchers want to gain a better understanding of how fat and muscle differ in the bodies of men and women of different ages across different ethnicity.

They also say obesity explains about 20 percent of cancers.

"We know that obesity contributes to the development of cancer and we want to stop the development of cancer when we can,” Dr. Randall Holcombe, UH Cancer Center director said.

UH believes health and fitness can be the answer.

“That's the idea that it would motivate you and you would also be able to see specifically where it came off like are my arms getting smaller, what would I look like if I do this,” Shepherd said.

All they need now are bodies to weigh in.
