I wonder how this device works? I checked out the company's web site [Japanese], and it appears to be one of those small tech-oriented places with some kind of university connection. They offer no proof that the product works well, but who knows. Here's a chart they publish showing how much variance there is between two servings of sirloin steak from different sources.
Joy World Pacific have concocted “Calory Answer,” a microwave-looking calorie counter that can display a food item’s macronutritional content using near-infrared analysis. By placing a food item in the unit, one can get the protein, sugars, and fat content of any food. The unit runs on Windows, although it was initially intended for Linux. Cost is currently at $28,000 (do you really need to know there are exactly 48.6 grams of fat in that Cinnabon?), but Joy World hopes to bring that down significantly. Otherwise, we know of a couple personal trainers who will take significantly less than that right now, and they will even hang out with you and tell you if that crap you’re eating is bad for you.
