 After initiation , the child regularly visits the hospital outpatient clinic where he or she is seen by the dietitian and neurologist , and various tests and examinations are performed . These are held every three months for the first year and then every six months thereafter . Infants under one year old are seen more frequently , with the initial visit held after just two to four weeks . A period of minor adjustments is necessary to ensure consistent ketosis is maintained and to better adapt the meal plans to the patient . This fine @-@ tuning is typically done over the telephone with the hospital dietitian and includes changing the number of calories , altering the ketogenic ratio , or adding some MCT or coconut oils to a classic diet . Urinary ketone levels are checked daily to detect whether ketosis has been achieved and to confirm that the patient is following the diet , though the level of ketones does not correlate with an anticonvulsant effect . This is performed using ketone test strips containing nitroprusside , which change colour from buff @-@ pink to maroon in the presence of acetoacetate ( one of the three ketone bodies ) .
