What is Metabolism?
Stop for a second, think of everything that’s going on in your body. Cells are re-generating, your brain is sending signals to all your involuntary organs, cells are travelling to carry oxygen throughout your body, the digestive tract is working on whatever you ate last, phagocytes are trying to eat up foreign pathogens, and the list goes on.

Medline Plus gives us this definition:
“Metabolism refers to all the physical and chemical processes in the body that convert or use energy.”
All of those thousands of functions going on in your body at any given time require energy. You may have had a doctor, nurse, or dietitian speak with you about your Basal Metabolic Rate, or BMR.
BMR is the baseline for how much energy your body needs to perform these basic tasks.
This is the bottom-line of energy (or calories) that your body uses just to function if you were to sit on the couch all day long and not move a muscle.
Your Metabolic Rate – or Metabolism – is generally calculated by an equation that factors your weight, height, and age.
If your BMR number is high, this means you have speedier Metabolism.
