GoBe's algorithms are very sensitive and register not only physiological processes related directly to the digestion of food, but also release of ketons into the bloodstream, which can happen during fasting, after significant physical activity, intermittent eating, intoxication from alcohol, and ketogenic diets. Although these processes are registered, at the moment there is no way to see how many calories were received from each source. We hope that such possibility will appear in the next firmware updates!
What this means if that if you drink a glass of water on an empty stomach, this may start up the digestion process and you will see calorie intake which seemingly does not correspond to the current intake, while it could be calories partially not digested from the past meal, or ketons received from the internal reserve.
If you are pursuing a weight loss goal, we recommend to observe the general trend for your energy balance over a longer period of time. Depending on the size of your goal, the longer you maintain to keep the energy balance negative, the more your weight will gradually go down and vice versa.
There is no direct correlation between the energy balance and weight loss due to the fact that calories received from burning fat and release of ketons into the blood are considered when calculating the energy balance. However, if your energy balance is negative at the end of the day, it still means that your total calories, received both from food and from the internal reserves, are less than what you burned, so it will contribute to your weight loss goal if this negative balance is maintained for a certain period of time.
