Now, the deontological path states that the answer relies in assesing whether the proposed therapy is good or wrong based on the action per se, and not the possible good consequences of the action. This path would assess what you are doing individually to each person, you are giving each individual uncertainty about his/her future and possibilities of dying or living if consuming high cholesterol and saturated fats diet, this is a wrong action, so this therapy cannot be applied.
