METHOD FOR DETERMINING AMOUNT OF ENERGY ENTERING HUMAN BODY WITH FOOD
A person's blood glucose concentration (Gi ) is measured periodically after beginning to eat, at a time interval (ti), and the following factors are determined over a designated time interval (Δti ): the increase in the amount of glucose in the blood plasma (ΔG(pl) i ), the amount of glucose e...

Zusammenfassung: | A person's blood glucose concentration (Gi ) is measured periodically after beginning to eat, at a time interval (ti), and the following factors are determined over a designated time interval (Δti ): the increase in the amount of glucose in the blood plasma (ΔG(pl) i ), the amount of glucose entering insulin-dependent tissues (ΔG(tis) i ), the amount of glucose expended on metabolic processes in the body (ΔG(met) i ), and the amount of glucose expended on metabolic processes in insulin-dependent tissues (ΔG(tm) i ). Then, the amount of glucose which entered the body (ΔG(∑) i ) over a given time interval (Δti ) is determined using ΔG(∑) i =((ΔG(met) i -ΔG(tm) i )+ΔG(tis) i +ΔG(pl) i )/K 4, where K 4 is a coefficient which takes into account the amount of glucose which enters the blood, with the exception of the glucose detained in the liver, which is then used for determining the amount of energy which enters the body with food over the given time interval (Δti ). The method allows for taking measurements while eating and for determining the amount of energy entering the body over small intervals of time, tracking how much energy is received over time while taking into consideration the individual characteristics of a person's body in accordance with the absorption of specific food products. The invention can be used in creating technical means for monitoring a person's functional state, and specifically for monitoring a person's weight.
Selon l'invention, après l'absorption de nourriture, on mesure à un intervalle de temps ti la concentration de glucose dans le sang d'une personne Gi et on détermine pour un intervalle de temps donné Δti : l'augmentation de la quantité de glucose dans le plasma sanguin ΔG(pl) i , la quantité de glucose ΔG(tis) i pénétrant dans les tissus sensibles à l'insuline, la quantité de glucose ΔG(met) i dépensée pour les processus métaboliques dans l'organisme, et la quantité de glucose ΔG(tm) i dépensée pour les processus métaboliques dans les tissus sensibles à l'insuline. On détermine ensuite la quantité de glucose ΔG(∑) i pénétrant dans l'organisme de la personne pendant l'intervalle de temps donné Δti de manière que ΔG(∑) i =((ΔG(met) i -ΔG(tm) i )+ΔG(tis) i +ΔG(pl) i )/K 4, où K 4 est le coefficient prenant en compte la quantité de glucose passant dans le sang à l'exclusion du glucose retenu par le foie, ce qui permet d'estimer la quantité d'énergie pénétrant dans l'organisme d'une personne avec la nourriture pour un intervall |
