No, a calorie is not another term for carbohydrate. A calorie is a unit of measurement used to quantify the amount of energy that food provides when consumed. Carbohydrates are one of the three main macronutrients, along with proteins and fats, that provide energy to the body.
To elaborate, when we eat foods that contain carbohydrates, our body breaks them down into glucose, which is then used for energy. Each gram of carbohydrate contains approximately 4 calories. However, calories can come from various sources: carbohydrates, proteins, and fats. Therefore, while carbohydrates contain calories, the term ‘calorie’ encompasses the energy provided by all macronutrients, not just carbohydrates.
