Content declaration do not seem to affect people's choices, no
Considerable time has passed since the question was posted, and the claim has been changed. Now the claim says:
- A calorie chart in restaurants doesn’t lead to healthier choices. After speaking with, and researching my initial answer I feel compelled to change my first response from: A calorie chart in restaurants can lead to less healthy choices, too: A calorie chart in restaurants doesn’t lead to healthier choices.
This is a significant difference to my previous response, and I apologize for any misunderstandings or incorrect assumptions to the readers. The truth is: calorie menus in restaurants don’t lead to “LESS” healthy decisions, it/they simply don’t lead to “better” decisions.
So the claim is that calorie declarations do not lead to better nor to worse choices.
Is this claim supported?
Is seems so. From this Washington Post article there is a link to a study.
A Meta-Analysis to Determine the Impact of Restaurant Menu Labeling on Calories and Nutrients (Ordered or Consumed) in U.S. Adults

A systematic review and meta-analysis determined the effect of restaurant menu labeling on calories and nutrients chosen in laboratory and away-from-home settings in U.S. adults. Cochrane-based criteria adherent, peer-reviewed study designs conducted and published in the English language from 1950 to 2014 were collected in 2015, analyzed in 2016, and used to evaluate the effect of nutrition labeling on calories and nutrients ordered or consumed. Before and after menu labeling outcomes were used to determine weighted mean differences in calories, saturated fat, total fat, carbohydrate, and sodium ordered/consumed which were pooled across studies using random effects modeling. Stratified analysis for laboratory and away-from-home settings were also completed. Menu labeling resulted in no significant change in reported calories ordered/consumed in studies with full criteria adherence, nor the 14 studies analyzed with ≤1 unmet criteria, nor for change in total ordered carbohydrate, fat, and saturated fat (three studies) or ordered or consumed sodium (four studies). A significant reduction of 115.2 calories ordered/consumed in laboratory settings was determined when analyses were stratified by study setting. Menu labeling away-from-home did not result in change in quantity or quality, specifically for carbohydrates, total fat, saturated fat, or sodium, of calories consumed among U.S. adults.
