What is metabolism?

Metabolism refers to all the activities that take place in your cells.

Metabolism is a combination of all the activities that continuously take place in your body. Think of your metabolism as two main crews working together: a construction crew and a demolition crew.

The Demolition Crew

The demolition creates energy by breaking down:

  • Carbohydrates, fat, and protein in the food you eat.
  • Energy stored in your liver, body fat, and muscles.

Waste products are created in this process and removed from your body when you sweat, exhale and go to the bathroom.

The Construction Crew

The construction crew uses this energy to build:

  • New material needed by your cells.
  • Tissue to repair and maintain your muscles, bones, and skin.
  • Stores of energy in your liver, muscles, and body fat.

Your body needs energy for everything, from thinking to breathing to walking up stairs.
