This is a device and subscription to a training and nutrition program. You start off with a session with your personal phone coach. The bodybugg program is customized based on your age, weight, height and goals. This "diet" works off the simple principle of weight loss of having the number of calories burned each day through exercise, exceed the number you intake through eating. The device fits around your arm and monitors how many calories you burn, so you keep track of those you eat, input that number into your Bodybugg and find out if you are heading in the right direction.
I used this for over one year and it was great. By checking my calories burned versus what I was eating I was able to maintain a consistent “calorie deficit” and lost 20 lbs.
I have used the bodybugg v3 since the third week of january. I have lost 25 pounds. Like having a calorie coach with you, worth the 300 dollars.
