The new health gadget that acts similar to breathalyzer will help you lose your excessive weight, telling you how much calories you need for this purpose.
The ReeVue Indirect Calorimeter is a medical device that checks person's metabolic rate and tells the optimal amount of calories you need. The device comes with the tube, where you have to inhale and exhale slowly for about 10 minutes to measure how much oxygen your body uses and gives you detailed information on the amount of calories you need in a rested state.
For example, if you find out that you burn fewer calories than normal, you either should exercise more or eat less than this amount to lose weight.
The ReeVue Indirect Calorimeter is mostly available in some health clubs and centers.
