Taking the time to measure your portions doesn't necessarily mean you will be eating less — you'll just be eating the number of servings your body needs. Certain foods are calorically dense and pack more calories than you think.
Marion Nestle, a Paulette Goddard professor of Nutrition, Food Studies, and Public Health at NYU, told The Atlantic why portion control is so important.
"Large portions make you eat more," she said. "If I could teach just one thing about nutrition, it would be this: Larger portions have more calories."
