I suggest, before making any other changes, to get a clear picture of the effect of his diet. When he eats, what he eats, when you are testing and when you are getting ketones and in what relation to his eating habits. Test urine throughout the day for a few days.
If you make numerous changes at once (quitting Mag, removing fruit, changing diet) and something goes well or poorly you don't know what caused the reaction because you did more than one change.
