Nutrient calculation is based on the total number of calories absorbed and what this energy level corresponds to in terms of macro nutrient amounts.
The nutrients you see in the app may not reflect the nutrient value of a particular meal you might have had, because the device tracks calories received both from food and from your body’s internal reserve.
If for example, you did a workout and a lot of energy was released from your internal reserve, the app will reflect this additional carb intake, and the total number of carbs consumed would be higher than you actually consumed from food on that day.
You may also see, for example, that the app shows less protein than you actually consumed. Protein usually takes much more time to be digested and absorbed by your body than other macronutrients. This depends on many factors, such as the amount of protein consumed, what other foods it was consumed with, the speed of your metabolism, your level of physical activity, and your health status etc. For this reason, some parts of your meal may get digested later in the day or even the next day and you will see a reflection of it in the app.
Please note that GoBe is designed in compliance with the conditions of a healthy nutritious diet. Fasting or severe dietary restrictions (i.e., a ketogenic diet) can affect the accuracy of the device. We plan to add support for diet mode in future GoBe releases.
Keep in mind also that this feature is still in beta with us. We are working on improving it and providing you the most accurate results.
