(HealthDayNews) -- A large part of weight control is estimating portion sizes -- so you have some idea of how many calories you've eaten. But how well do people do this?
Not very well, according to a study by researchers at the University of Albany in New York.
As reported in the journal Eating and Weight Disorders, the researchers gave 41 women samples of chocolate ice cream and asked them to estimate the number of calories they ate, and the portion size.
All the women underestimated the number of calories -- but they also incorrectly estimated the number of cups of ice cream they'd eaten.
