What is the ketone test?
This is a simple urine test which indicates the presence of ketones. The mild ketosis induced by the Cambridge Diet ensures that sufficient ketones are produced to give adequate energy with some left over which are passed into the urine. Two simple tests are available from the chemist – Ketostix and Ketur-Test. They are plastic strips with a felt tip. The tip will react and turn pink if ketones are present in the urine. Most dieters achieve ketosis after three days on the sole source programme. If, after this time a test gives a negative reading (the top does not change colour), it is reasonable to assume that the dieter is deviating from sole source and taking in extra carbohydrate. On the other hand, a positive reading (the tip turns pink) can be very motivating for someone who is in a pre-menstrual plateau. It is tangible evidence that their body is indeed still burning off fat, even though the loss is not showing on the scales.
