Where do you start with this one? I will endeavour to explain to you in a simple way that we all understand, as there are so many explanations out there on how many calories you should take depending on your body type and your activity levels.
Calories = energy nutrients. In other words, we get our calories from food, carbohydrates, proteins and fats. These energy nutrients are made from carbon (fuel) and these nutrients allow us to do muscular work and transfer electrical energy between nerve cells. They also help to regulate the body’s temperature.
