I LOVE LOVE LOVE my bodybugg....
I got started with it 3 or 4 years ago when I went on a "lose weight kick". The trainer I worked with recommended it. I used it for 3 months, didn't keep up my part of the bargin (you know, the working out and eating right part) and didn't lose any weight. So I promptly put it away in a drawer.
Fast forward to last spring. After graduating I didn't realize exactly how much weight I had put on in school until I went to the doctor and actually saw the number on the chart. I went home and cried. Then I pulled out my bodybugg, reactivated it and got to work.
I lost 50lbs and went from 36% body fat to 21%.
It wasn't easy and it's not a magic pill BUT what it does do is remind you that it's all a numbers game. If you eat more calories than you burn you gain, if you burn more than you eat you lose. And when the numbers are right in front of you it's hard to ignore.
A couple things to consider:
Monthly fee to use the online program: 14.99 I think + the cost of the bugg and misc stuff you need to work it.
It takes some time and effort to keep up with the food log input but once you get in a routine it gets easier.
It's useless if you don't honestly record what you're eating and take the time to input foods you eat that aren't in the database. Remember, if you lie to yourself about portion sizes the only one you're hurting is you.
So...that's my experience. If you have any questions or want some ideas for tricks I learned just PM me, I'm happy to discuss it.
Good luck-you can do it!
