Which of the following calorie sources typically falls under 'empty calories'?

Empty calories refer to foods and beverages that provide high amounts of energy (calories) but very few nutrients such as vitamins, minerals, fiber, and essential fatty acids. Sweetened beverages are a prime example of empty calories because they often contain high levels of added sugars and calories without any significant nutritional benefits. These drinks can lead to weight gain and do not satisfy hunger, as they lack the substances needed for proper nutrition.

In contrast, whole grains, vegetables, and lean proteins offer a variety of essential nutrients. Whole grains provide complex carbohydrates, fiber, and various vitamins and minerals. Vegetables are rich in vitamins, minerals, fiber, and antioxidants, contributing positively to overall health. Lean proteins supply amino acids necessary for body repair and maintenance, along with other nutrients that support bodily functions. Therefore, sweetened beverages stand out as the source that typically represents empty calories.
