Validation by University of California Davis (California, USA)

By the end of 2018 the Foods for Health Institute at the University of California Davis has completed a validation study of HEALBE GoBe2 Smart band. A 14-day study was conducted on 27 adult volunteers between the ages 18-40 years old, 11 men and 16 women. The results of the study confirm the accuracy of GoBe2 in automatic tracking of digested calories.

Calorie counting accuracy was assessed by comparing data from the manually recorded intake of volunteers and the data from the GoBe2. Study meals were prepared in a UC Davis commercial kitchen by trained food service personnel following a stringent HACCP protocol. A research team analyzed the calorie content of each individual menu item. They weighed, recorded, portioned, and served the food and recorded plate-waste for all study volunteers at each meal served in the dining facility. To determine how well the device and its algorithms estimated the actual diet of volunteers, the correlation between recorded intake and data from the GoBe2 was examined. Data were transformed into three-day rolling averages, and the GoBe2 accuracy was 87%. Over the two week period, the GoBe2 showed an accuracy of 89.6% in measuring calorie intake.

The ability of the HEALBE GoBe2 to accurately track calorie digestion significantly differentiates it from other wearable health monitoring smart bands. The level of accuracy exceeds the effectiveness of comparable devices, as other wearables rely on a human recording of diet and calorie ingestion, and the potential for human error in that process typically puts accuracy at well below 50%.

Validation by Guangzhou Red Cross Hospital (Guangzhou, China)

In October-December 2018 Guangzhou Red Cross Hospital (Guangzhou, China) has conducted pilot studies to test the accuracy of Calorie Intake and Hydration measurements by GoBe2™ Smart band in Asia.

The study compared the calorie intake accuracy between GoBe2™ measurements and a direct observation method. Food and nutrient intake were measured for 13 healthy volunteers (3 men, 10 women) over 28 days. The received data was grouped in 3-day intervals to evaluate an average calorie intake per day.

The average calorie intake rate by GoBe2™ differed from the reference method by ca 250 Kcal/day, i.e. 16%. When compared for all the study period, the day by day energy intake data provided by GoBe2™ technology had a good consistency with daily energy intake provided by food diary records, and relative difference between these two methods was consistently ca 12% only.

The study concludes that GoBe2™ ’s calorie intake measurements correlate well enough with the data by the direct observation method and that the GoBe2™ wristband can be a good device for people to monitor their food energy intake.

The hydration module was tested within the same audience. The test has proven an ability of GoBe2™ to evaluate both a dehydration level after moderate physical activity (like walking and jogging) and rehydration level after water drinking for individuals.
