Improving compliance with VLCD by reducing halitosis

We propose a double blinded randomised controlled trial to test the effectiveness of enterically delivered peppermint oil (Breath Pearls™) to improve the perception of breath quality for patients who are on a VLCD. If this trial confirms that patients have the perception of improved breath quality, we will plan to further investigate the mechanism by which this occurs and also extend the study to other cohorts that may benefit from this treatment.
