atrina’s switch to recording on an app is
certainly at the forefront of technology. An
emerging technology called teledietetics also
allows for a different kind of intervention for people
watching what they eat or working at weight loss.
Teledietetics uses smartphone technology to
enable people to apply nutritional knowledge from
consultations with a dietitian to the balanced diet and
portion size information of the foods they are eating.
According to a January 2014 article in Telemedicine
and e-Health, “By recording their patients’ dietary
intakes into a programmed system, dietitians can
promptly analyze their food energy and nutrients. The
program can then use the data to generate instant
and individualized evaluations via online reports. These
reports can educate individuals on how to modify their
diets and gradually change their behavior to encourage
healthy eating. Seeing the factual data on food energy
and nutrient values establishes a mindfulness effect,
helping the individual to change.”
In a study in Hong Kong, researchers compared one
group that used a paper diary and another that used
an electronic diary to a control group. Each group
got the same nutrition education, but the paper diary
group received comments from dietitians online and
the electronic diary group received detailed calorie
and nutrient information online. Both diary groups lost
weight and reduced their BMI, but the electronic group
lost only body fat while the paper diary group lost both
fat and lean muscle mass, which eventually can make
losing weight more difficult. The researchers concluded
that the participants who used the electronic dietary
records had a better understanding of healthy eating.
