What is a calorie?

While a calorie is essentially a unit of measurement, there’s more to it than that. “A calorie is the amount energy in food that allows the body to function,” Josephine Tutrani, a nutritionist and dietician, tells Parade. “Carbohydrates, proteins, fats, and alcohol all provide food energy or ‘calories’ that the body will either use or store.” Some foods contain few calories, such as lettuce, while others are calorie-dense. A half-cup of peanuts, for example, contains nearly 400 calories. But all are essential, in their own way. Calories keep the body running.

How do calories contribute to or affect weight loss?

In order to lose weight, you need to take in fewer calories than you burn, creating a deficit. “Past thinking used to have us believe that in order to lose one pound of fat per week we would have to have a deficit of 500 calories per day, either through food or exercise,” Tutrani says. However, recent findings question this concept, as this formula isn’t an exact science and there are numerous factors that contribute to weight loss.

Are all calories created equal?

The answer to this question is no. While all foods contain calories, all calories are not the same. “Certain calories can be [and are] better than others,” Tutrani says. “100 calories of potato chips, for example, will store much more fat than 100 calories of broccoli. This is because real, fresh, whole foods contain more fiber and nutrients than their processed counterparts.” These foods are also digested more quickly. “Fruits, vegetables, lean proteins, and other like foods don’t just increase your metabolism, they keep you feeling more full and help decrease the release of fat-storing hormones.”
