Researchers from the University of Sydney's Boden Institute of Obesity, Nutrition, Workout & Eating Disorders have developed a portable and method that is easy-to-use assistance individuals estimate portion size only using their hands.
within the research that is first-ever assess the precision of hand-based means of measuring meals portions, little finger width had been utilized as a 'ruler' to measure the measurements of foods and cups of liquids. These measurements, coupled with geometric formulas of amount and food thickness factors, led to a target and estimate that is acceptably accurate of weight for the food.
The research, led by PhD prospect and Accredited Practising Dietitian Alice Gibson, had been posted into the Journal of Nutritional Science.
Ms Gibson's tries to realize her own eating habits motivated her to pursue this research, as part of her doctoral thesis at the University of Sydney's Charles Perkins Centre into clinical loss that is weight.
"I finished a food diary for a week and that is when I realised how hard it will be for people to accurately calculate the quantity that's true of on their plates, particularly for difficult-to-measure meals like lasagne. It struck me I had no available or way that is reliable of so," she stated.
"we realised there was clearly a space looking for individuals trying to eat sensibly when they're out and about, if they do not have use of a collection of scales."
Comparing calculated weights from the 'finger width' method aided by the weight that is true of food, Ms Gibson and her colleagues also tested the utilization of fists, finger tips and thumbs. The research examined the reactions of 67 participants who were tasked with estimating the serving sizes of 42 meals that are pre-weighed liquids.
All hand techniques were compared with household practices (cups and spoons) and size that is subjective (small, medium, large).
The 'finger width' method ended up being found become more accurate than home measures and size descriptions for calculating meals portions. Eighty percent of food sizes evaluated using the 'finger width' method had been within 25 percent of their weight that is true with 29 per cent of these believed utilizing the household method.
"While more research is necessary to fine-tune the technique, i do believe there's real possibility this tool to be included into electronic platforms such as smartphone applications so your calculations are automatic and food that is estimating on-the-go is more accurate," said Ms Gibson.
"Better accuracy when food that is calculating drink consumption will allow dietitians to tailor nutrition advice and tips even more, fundamentally benefiting customers," she added.
In early recognition for the extensive research, Ms Gibson ended up being recently awarded the Dietitians Association of Australia (DAA) President's Award for Innovation for her device.
The prize is in Honour regarding the memory of Josephine (Jo) Rogers AM, a University of Sydney graduate and President and Vice?President associated with Dietetic that is australian Councilthe forerunner of DAA) between 1959 and 1967.
"It is fantastic to own this tool validated, providing an easy-to-use, evidence-based resource which will be offered to all practitioners anywhere, anytime," stated DAA President Liz Kellett.
Ms Gibson and her team are now actually seeking Sydney-based individuals for clinical weight-loss trials to test this process that is new. To find out more or even to register your interest e-mail tempo.diet@sydney.edu.au.
