Half a croissant, on a plate, with a sign in front of it saying '50c'

It's as much a hovercraft as a pancake is a waffle.

it is troublesome and hard to calculate calorie and nutrition for people who are suffering from diet , diabetes , hearttrouble ,kidney and so on. This device calculate calorie and nutrition immidiately and suggest you to have some more or half cut or add some nutrition in your own condition.you just put it over foods which you cook or someone cook or delivery whatever. This device is hand-portable.you can use this one in restaurants and anyplace. you can enjoy your meal without anyfear.

bodyfat scale http://www.scalesgalore.com/pbodyfat.htm
This could be reengineered to calculate food fat content. [cheeselikesubstance, Aug 02 2001, last modified Oct 21 2004]

Why wannabe dieters need these things http://www.nytimes..../dining/02CREM.html
Turns out that Tasti D-Lite is thrice as fattening as advertised and fatty to boot. And CremaLita is almost as bad. Given they all taste like cardboard, you kinda wonder why anyone bothers. [DrCurry, Oct 02 2002, last modified Oct 21 2004]

They're sort of cheating: you have to enter the code for the food you've placed on the scales. But is does keep running totals. [DrCurry, Jan 05 2005, last modified Sep 19 2005]

       Maybe food manufacturers could make this easier, with giant, extra long barcodes on their products which give you a molecular listing of their contents. Or maybe a little chip on the shelf you are buying them from. Your hand held device could hold details of your diet requirements and allergies etc and tell you what and what not to eat, maybe recommending foods to you and your family, friends, whomever you are buying food for... Fantastic !

       I agree. Waugsqueke Is Being Nice, Incidentally.

       You could do a quick chemical oxygen demand test right at your restaurant table, just boil a sample of your meal in a flask with a mixture of sulfuric and nitric acid for an hour or two...cool...titrate. Wouldn't give you calories per se, but would give a pretty good idea of oxidizable contents. No, scratch that, bad idea, waiters would call a HAZMAT team and bust ya. What you'd need is a tricorder, so yeah, WIBNI.

       Don't write off this idea so soon! I don't think this is wibni. Measuring calories and exact molecular composition may be too ambitious, but I'm sure a device could be designed to check for sugars, salts, and fats. There's a bathroom scale that checks my precise body fat ratio; surely that technology could be tweaked to this purpose. Great idea, everlasting. Here's a croissant for you to analyze.

       Hey, absterge, howzit going? Good point but tongues can be tricked by non-nutritional saccarides and such.
Dog Ed, Aug 03 2001
  

       Hi, [absterge].

       I suppose it'd be silly to suggest one read the side of the package, at least in the US.
