Gadgets help people stick to customized weight loss plans

Fitness experts say motivation is the single biggest roadblock to realizing weight loss and performance goals.

"People make a resolution to lose weight and get in shape, but that resolve is quickly lost without guidance and support," said Rob Herzog, director of the Memorial West Fitness Center.

The problem is, many can't afford the cost of a personal trainer and nutritionist.

"Having one or both is ideal, but the neat thing is there are now a variety of gadgets on the market that can provide similar support and necessary information to stay on track," said Herzog.

Memorial West fitness trainer Luis Perez put one gadget, the MyTrak M2 Activity Coach, to the test.

For $129 a year, you can purchase the palm-sized device and hook up to a web-based support system. 

"If you're challenged by computers like I am, it's going to take you a little time to put all the information in, but once it's in, you just put it on your waist and go about your day and do your exercise," said Perez.

The M2 device measures steps taken, distance traveled and calories burned.

"The web connection is key because this is where you get guidance from a personal trainer after putting in information about your overall health and fitness goals," said Herzog. 

While the device keeps track of calories burned fairly effortlessly, users need to input their own dietary intake, which can be difficult.

"To put in a food diary every day can be pretty labor-intensive," said Herzog.

Along with a personal online fitness coach, users have access to social media platforms for even more support.

"I was really impressed with that part of it, the ability to reach out to others who are trying to lose weight and get in shape and share experiences through social media," said Herzog.

Users can also follow their own progress with personalized charts and graphs.

"There's a group of people that need that motivation, need to see the chart to know you're working hard and that it's paying off," said Perez.

Other similar devices on the market include Fitbug, which costs $99 and even measures sleep quality. 

A device called Body Media also tracks daily activity and sleep patterns with a cost ranging from $179 to $199.
