Portion sizes: gotta hand it to the Aussies

Australian researchers have developed a portable and easy-to-use method to help people estimate portion size using only their hands.

Claiming to be the first-ever study to assess the accuracy of hand-based methods for measuring food portions, finger width was used as a “ruler” to gauge the dimensions of foods and glasses of liquids. These measurements, combined with geometric formulas of volume and food density factors, resulted in an objective and “acceptably accurate” estimate of the weight of food.

The findings suggest that there is potential for the tool to be incorporated into electronic platforms such as smartphone apps to help estimate food intake on the go more accurately.
