[Structural and functional characteristics of the brain and their role in the development of eating behaviour in obesity: A review].

Obesity is a major public health problem that requires new approaches. Despite all interventions, the behavioural and therapeutic interventions developed have demonstrated limited effectiveness in curbing the obesity epidemic. Findings from imaging studies of the brain suggest the existence of neural vulnerabilities and structural changes that are associated with the development of obesity and eating disorders.

[Body composition in sarcopenia in middle-aged individuals].

Unlabelled: Sarcopenia is characterized by a progressive loss of muscle mass, strength, and function, leading to poor outcomes and reduced quality of life. In middle age, the decrease in muscle mass begins to be progressive. Bioimpedancemetry allows diagnosing this condition before the onset of clinical symptoms.
