Method of monitoring diet
First Claim
1. The method of determining total body fat of a human subject comprising introducing a sample of alveolar air from said subject into a device capable of measuring both acetone and alcohol quantitatively in amounts at least as small as 1 microgram per liter and measuring the amount of alcohol and acetone in said sample to establish a base measure;
- introducing into said subject exactly known and predetermined amounts of alcohol and acetone, permitting said alcohol and acetone to be distributed through the water and fat of said subject, introducing another sample of alveolar air from said subject into said measuring device, measuring the amount of alcohol and acetone in said sample, determining the ratio of alcohol to acetone attributable to said introduced amounts of alcohol and acetone in the said alveolar air, and computing therefrom the total body fat of said subject.

Abstract
A method of monitoring diet includes introducing a sample of aveolar air into a device capable of measuring acetone quantitatively in amounts at least as small as 0.3 mcgm/l (microgram per liter); measuring the amount of acetone in the sample; converting the measurement into immediately recognizable humanly intelligible form, and displaying the measurement in that form within a period of no more than five minutes after the sample is introduced into the device.
