A fast metabolism is often considered the key to effortless weight loss. There are people who can enjoy all the culinary pleasures without gaining a gram. This idea of ”fast metabolism” is very popular, but what is it really? Find out what really influences the level of thinness and how it is possible to maintain a healthy weight.
Explanation of the process of metabolism
Metabolism is the complex process by which the body transforms the food it consumes into energy. Scientists often measure this process through the metabolic rate, which represents the amount of energy the body expends over the course of a day.

The basal metabolic rate (BMR) is the energy used by the body to maintain its basic functions, such as breathing, blood circulation and regulating body temperature. All these activities require energy, and represent 60 to 80% of daily energy expenditure.
However, metabolism is not limited to BMR alone, as physical activity (15 to 30%) and digestion (a few percent) also influence daily energy expenditure.
The muscles: a major importance
Muscles play a crucial role in metabolism. Compared to other cell types, muscle cells are particularly active and require a lot of energy for their contractions and repair.

Thus, the greater the muscle mass, the higher the BMR. This means that people with more muscle have a metabolic advantage because they burn more calories, even at rest.
weight and metabolism
Although weight may be linked to metabolism, it is not the only determining factor. Two individuals of similar weight can have very different body compositions, which influences their metabolism in distinct ways.
For example, a lean person may have significant muscle mass and little body fat, which gives them a high metabolic rate despite their weight, such as top athletes or professional dancers. In contrast, a heavier person with less muscle mass may have a slower metabolism. Thus, body composition is more important than the weight itself in determining the level of thinness.

Other determining factors
Besides body composition, other factors can influence metabolism. Genetics plays a role, although relatively moderate, in determining BMR. An active lifestyle and an unbalanced diet are also elements that influence weight loss. Eating habits, physical activity and stress management all play a key role in regulating metabolism.
Rapid metabolism is an often misunderstood concept. Science reveals that body composition, especially muscle mass, is a major determinant of metabolism. Thus, it is essential to adopt an active lifestyle and to favor a balanced diet to optimize our metabolism.
