There are plenty of new products designed to track your activity and how much energy you are using but there is no device to automatically track how much energy you consume. Manually tracking your food intake has always been the most common method to do this and more recently new apps have come out that make this a little easier. But you still have to manually input everything you eat and measure how much. This can be very tedious and self reporting can often be inaccurate. With the EaterTrack this is done automatically, all you have to do is wear it, turn it on, and eat.
