Use of the Lumen by persons below the age of 16 or by individuals suffering from metabolic/respiratory medical conditions or from conditions which may be affected or aggravated as a result of dietary changes, such as diabetes, clinical obesity, severe asthma, COPD, may result in inaccurate output and readings of the Lumen or otherwise in dietary suggestion by Lumen which may cause damage when implemented by persons suffering from such conditions. It is therefore recommended that such individuals either do not use Lumen or consult their doctor before purchasing.
