Is a calorie is another term for carbohydrate?
A calorie is not another term for carbohydrate. We can get calories from carbohydrates, but we can also get calories from proteins and fats.
Calories are essential for life. An adult human needs to eat between 1,600 and 3,000 calories per day, depending on their size, metabolism, and other biological factors. If we don’t consume enough calories, our energy levels will be low and we won’t function as well.
