Growing up, in school, on TV, and in magazines, we constantly read about “calories.” We were taught that calories are all we need to worry about when it comes to managing our weight. A calorie deficit meant surefire weight loss, while a calorie surplus meant guaranteed weight gain. However, have you ever stopped to ponder the source of these calories and consider that not all calories are created equal? The idea of counting calories is outdated and makes no physiological sense. That’s where macronutrients comes into the picture.
