Saciación vs saciedad: reguladores del consumo alimentario

The study of the factors that regulate high energy food intake is especially relevant nowadays due to the high prevalence of overweight and obesity. Food intake regulation can be divided in two basic processes, namely satiation and satiety. Satiation is the process that determines the moment in which feeding stops and regulates the amount of ingested food during a single meal. Satiety is the interval between meals and regulates the time elapsed between two meals. The longer the interval, the lower energy intake. Each of these processes are regulated by different factors, which will be herein reviewed.
