It's called 'the body bugg' and it's helping them shed pounds. NBC's Marianne Favro has that Your Health story.

Tracey Nowell is reviewing the most important report of the day.

It shows a deficit, but in this case that's a good thing. Tracey burned more calories than she consumed.

"So I did really well that day. I hit my target and it was a great day," said body bugg user Tracy Nowell."

Every morning Tracey straps this body bugg on her arm.

It measures how many calories she burns.

"I'm picking up the kids here and running around and we went to Costco that particular day and I'm unloading groceries right here," said Nowell.

The body bugg may look familiar. This season contestants in the NBC hit reality show "biggest loser" are wearing the high tech arm-band to help them lose weight.

Now you can try it out at some local gyms.

It costs about $349 and Tracey says it was worth every penny.

"I've had a lot of success," said Nowell. "I have been able to drop about 12 pounds in 13 weeks."

"It makes sure that when you're not with your trainer or working out, that you are still moving around and eating what you're supposed to be eating, so it definitely holds them accountable," said personal trainer Michelle.

Tracey logs every morsel of food she eats, and the program does all the math.

Calculating everything from calories to protein, fat and sodium.

These details have helped Tracey ban butter.

"With the Body Bugg I am able to have a lot of success because it challenges me to be honest and have conscientious eating for the first time in my life," said Nowell.

Now Tracey parks her car far away from her destination to burn extra calories walking.

She says because the body bugg has inspired her to move more and eat less, she plans to wear it the rest of her life.

MS Research

New research shows some interesting data about multiple sclerosis and families.

Researchers at the University of Buffalo found that patients with a family history of MS often have more severe cases than those without a family history.

By using scans of MS patients brains they measured the number of lesions and the degeneration of the brain.

Researchers found familial MS patients had significantly more brain lesions and lower brain volume than those without.

Remembering Medication

Do you ever have trouble remembering the dosage and names of the medications you take?

New data shows that you aren't alone when it comes to remembering.

Northwestern University researchers found almost 50% of patients being treated for high blood pressure couldn't accurately name their medications.

Researchers say their findings cause concern because if a medical chart is not available, doctors wrongly prescribe crucial medications.

And suggest patients write down or bring their prescriptions with them.
