How does GoBe2 track calorie intake?

Why count calories?

The golden rule of nutrition is a concept called Energy Balance. This concept says that to be healthy and maintain a normal weight, you need to burn as many calories as you eat, but to lose weight, you must consume fewer calories than they burn. Calories in must equal calories out to maintain.

How does it work?

GoBe2 tracks your calorie intake automatically, no manual logging is needed. The device does not directly track what you eat, rather it tracks the energy consumed by your body. 

GoBe2 uses patented FLOW Technology and an impedance sensor to analyze changes in your body’s glucose concentration. As glucose concentrations rise, cells absorb glucose and release water. The impedance sensor sends high and low-frequency signals through your tissue to measure the fluid moving in and out of your cells.

FLOW Technology then applies this information to an advanced algorithm to analyze this data and determine calorie intake. In general, if you consume fewer calories than you burn, GoBe2 will show a caloric deficit for that day.

Accuracy will be diminished on fasting diets or high protein/high-fat diets. We are continually working on our algorithm and are working on a “diet” mode we hope to debut soon.

GoBe2 registers calorie intake at the time when calories are absorbed by the body, at the stage of nutrients getting into the blood.

Keep in mind, different stages of the digestion process take different amounts of time:

1-2 hours - the process of chewing and swallowing;

3-4 hours - the handling of food by digestive fluids;

4-8 hours - digestion process;

5-9 hours, and sometimes more than 24 hours - food is delivered to the absorption area and enters the blood. Some of these processes occur simultaneously, so the first portion of digested food may enter the blood after 15-30 minutes, but the main part of the meal may take 3-4 hours to be digested, and the absorption period may overlap with the next meal.

Depending on the composition of the meal, 90% of the food can appear in the blood after one hour (sweets, sugar) and up to 9-10 hours (complex dishes with meat and side dishes).
