So what's with the metabolism now? Strictly speaking, there are several metabolic processes in the body in which different substances - energy in the form of carbohydrates and fats, cell building blocks in the form of protein - are used in the body.

When it comes to weight and weight loss, the energy metabolism is particularly interesting. Energy metabolism is the process by which the calories supplied to the body from outside are converted into energy. This process takes place constantly in every single cell of our body, and at the same time all organs of our body play their role, just like the different instruments in an orchestra.

The food we eat is broken down into its individual components in the gastrointestinal tract. These are then absorbed into the bloodstream via the intestinal mucosa and transported to where they are needed. Our cells resemble small incinerators in which the calories consumed in the food are burned, creating heat energy.

This energy allows us to move our muscles in the first place - every movement, from pressing the remote control to running a marathon, requires energy. In addition to the energy metabolism, the so-called building metabolism also takes place, which serves to build up and maintain body mass and for which primarily protein, but also fat and other substances are needed.
