(Telegraph) Breath test to tell when the fat starts to burn off in the gym

A breathalyser that can reveal how much fat you are burning off at the gym is being developed by British scientists.

The device is being built to pinpoint the moment when a sweaty session on the treadmill finally starts to pay off by detecting when the body has used up its supply of food energy and switches to breaking down fat instead.

Exercise machines currently estimate when people have entered the “fat burning zone”. The breathalyser works by picking up minute changes in the levels of a molecule called acetone in people’s breath, which is given off when the body starts to burn fat.
