I'm afraid that information transparency tends to be a lot more effective than admonitions. Also, it's considerably less hassle to me if I can check the calories upfront and order a meal I can eat in full, rather than make a series of evaluations, calculating the marginal dis/utility of an extra bite (is my hunger satiated? if so, do I stop eating because my hunger is satiated or continue because the food still tastes great?). There's also a longstanding norm against leaving food on your plate which can make people feel uncomfortable about not finishing. The emphasis calorie counts put on ordering a meal which you can feel comfortable about eating in its entirety are also encouraging restaurants to switch to smaller plates, which helps change our perception of what a "normal sized meal" is. And it's less wasteful.
