Abstract

The purpose of the present invention is to provide a ketogenic diet monitoring device for managing the effective state of a ketogenic diet for an animal individually. The ketogenic diet monitoring device of the present invention has a configuration in which the amount of metabolite in gases carried from the inside to the outside of the body of an animal for which the effective state of a ketogenic diet is being managed is measured once and/or a plurality of times over time and monitored.

First claim

The invention claimed is:

1. A method of managing a ketogenic diet ingestion amount using a ketogenic diet monitoring device, the ketogenic diet monitoring device to improve a disorder comprising one or more of cardiovascular disorders, type 2 diabetes, epilepsy, acne, cancers, polycystic ovary syndrome, neurological disorders, Alzheimer's disease, Parkinson's disease, and head injury in a patient or pre-patient of the disorder against which ingestion of a ketogenic diet is effective including:
an ingestion information acquisition unit for acquiring information about an amount of ingestion of a ketogenic diet ingested into a body of the patient or pre-patient;
an acetone concentration measurement unit for measuring acetone concentration that is an amount of acetone in a gas carried from inside to outside of the body of the patient or pre-patient,
a determination unit which, based on the information about the amount of ingestion of the ketogenic diet acquired by the ingestion information acquisition unit and the acetone concentration measured by the acetone concentration measurement unit, determines a state of metabolizing of the ketogenic diet by the patient or pre-patient,
a determination accumulation unit for accumulating the determination by the determination unit; and
a determination judgement unit for adjusting an amount of ingestion of the ketogenic diet of the patient or pre-patient based on the accumulated determination, the method comprising:
measuring the acetone concentration by the acetone concentration measurement unit;
calculating a rate of increase in the acetone concentration by the determination unit; and
adjusting an amount of ingestion of the ketogenic diet of the patient or pre-patient according to the rate of increase in the acetone concentration by the determination judgement unit, wherein
the measuring includes measuring the acetone concentration before and after ingestion of the ketogenic diet of the patient or pre-patient,
the calculating includes calculating the rate of increase in the acetone concentration based on a difference in the acetone concentration before and after ingestion of the ketogenic diet, and
the adjusting includes increasing the amount of ingestion of the ketogenic diet if the rate of increase in the acetone concentration exceeds a reference value set in advance, and decreasing the amount of ingestion of the ketogenic diet if the rate of increase in the acetone concentration does not exceed the reference value, and

wherein the increasing or decreasing of the ketogenic diet is by only an appropriate amount of ingestion that is necessary and sufficient to improve the disorder in the patient or pre-patient while avoiding excessive ingestion of the ketogenic diet.
