Ever wonder how many calories are really in that slice of pizza or that quiche?
The makers of the Tellspec device say it can analyze the chemical composition of any food in less than 3 seconds.
A spectrometer measures reflected light and sends the data to a smartphone app, so you can see the amount of calories, fat and sugar.
"When people have the ability to understand what's in their food and the ability to understand what those ingredients do, they'll think twice about eating them," Isabel Hoffmann, Tellspec CEO, said.
When the device moved from the unsweetened to sweetened chocolate, you can see it goes from 500 calories and 1% sugar to 560 calories and 25% sugar.
Hoffmann says most foods require multiple scans. The Tellspec can only read the surface and the food item has to be in their database.
"I know we have bread, but it's not recognizing those breads. This is the reason we are launching it for beta testers to build our database," Hoffman explained.
Test users can pre-order now. The price tag is $320.
For $100, there's a fork that's forces you to eat slower so you eat less.
It's called the new Hapifork. If you eat too fast it vibrates and flashes red. The fork also sends data to your smartphone.
"You bring food to your mouth and it will automatically count how fast you do it," Fabrice Boutain, HapiLabs CEO, said.
Another high tech device - glasses that make food look bigger and fool you into feeling full.
A small study by the Japanese researchers shows that people who wore the glasses ate nearly 10% less food than those who didn't wear them.
It's all about portion control and moderation, but technology may trick your brain to make it easier.
