Marion Nestle says in her book:
In some ways, the calorie environment could not have been more brilliantly constructed to overcome physiological controls of overeating.The new labeling initiatives have been really minor up to now. Wether they will have beneficial effects in the long run is still unknown. Calorie labeling should be extended when eating outside home and to alcohol.
The government has not paid enough attention to food regulation and specially to information about calories. In the book there is a guide for improvement. This is the previous step in any nudging effort. To be clear, information disclosure is the very beginning of any consumer protection and health promotion policy in this field.
