Individuals undergoing weight loss often perceive this period as being associated with dietary restrictions and prolonged endurance sports such as cycling, running, or swimming. During this time, many people stop weightlifting and do not use resistance exercises as the foundation for physical activity. However, numerous scientific studies indicate that strength training can be an essential component of weight loss, as it impacts fat loss and changes in body composition.
How a high amount of muscle mass aids in weight loss
A high proportion of muscle mass increases the resting energy expenditure, as muscles, being one of the most active tissues in the body, consume a large amount of energy, much more than adipose tissue, for example. This results in more calories burned over the course of the day. The process of fat reduction involves introducing a negative energy balance, which makes the body look for fat reserves but can also use muscle protein as a source of energy. This is beneficial not only in terms of improving body fat composition. Inadequate intake of macronutrients and the lack of strength training, which stimulates muscle growth, can lead to significant muscle mass loss. Incorporating strength training in the reduction process promotes anabolic processes in the muscles. Regular strength training can reduce muscle loss, enabling the avoidance of strict diets, improving body composition, and increasing strength.
