Automatically Track Your Calorie Intake! The Smart Band "GoBe3" Takes Health Management to the Next Level!

The American company HEALBE developed the smart band "GoBe3." It can measure calorie intake by detecting fluid movements within the body using a bioimpedance sensor. There is no need for blood tests or meal input; just wearing the "GoBe3" is sufficient, thanks to its innovative system.

Additionally, it automatically measures calories burned, providing a clear overview of the daily energy balance. It's highly convenient for supporting diet and health management. What technologies are behind the development of "GoBe3"?
 
When trying to manage calorie intake using apps or smart devices, users typically have to manually input every meal. Even logging three meals a day requires effort, let alone tracking snacks, drinks, and post-exercise refreshments. With "GoBe3," which automatically tracks calorie intake and body water levels, there's no need for meal input or calorie calculations. Indeed, it's a revolutionary product.

Measuring Fluid Movements Using Impedance Sensors

Obviously, the intriguing part is the system that automatically calculates calorie intake. How can a compact smart band worn on the wrist accomplish this?
 
"GoBe3 uses bioimpedance sensors to send high and low-frequency signals through the skin, measuring the flow of fluids inside and outside the cells, and calculates calorie intake through a proprietary algorithm," says Daria Potapova of HEALBE JAPAN.
 
As consumed food digests and absorbs, blood glucose levels rise, and cells absorb glucose, releasing intracellular fluid. This movement is measured.

Furthermore, it also provides insights into the PFC balance (the ratio of protein, fat, and carbohydrates to calorie intake). Carbohydrates get absorbed quickly, resulting in a rapid rise in blood glucose levels, while proteins and fats take longer to digest and absorb, causing a gradual increase. Therefore, by analyzing the speed of glucose absorption, the quantities of each can be calculated.

If such a sensor exists, one might wonder why it isn’t adopted in more smart devices, like heart rate sensors or accelerometers. Or is it something special that other companies can't integrate?
 
"The impedance sensor itself is not developed by our company, nor is it something particularly special. For example, it is used in body composition scales that everyone uses at home or at the gym. What's unique is the data analysis technology we’ve developed. Over ten years, we have researched human metabolism models and developed algorithms to calculate calorie intake based on glucose curves."
 
The analysis technology, named FLOW Technology, has obtained patents worldwide. For measurement and analysis data, verification experiments have been conducted at independent third-party institutions, including the University of California, Davis (USA) and Guangzhou Red Cross Hospital (China). The experiments used the previous model, "GoBe2," and received evaluations indicating that the calorie intake accuracy level is 89.6%. This can be considered highly accurate.
