Neural and hormonal mechanisms involved in the control of eating behaviour, including the role of the hypothalamus, ghrelin and leptin
The brain and hormones work together to control when you feel hungry and when you feel full. A brain structure called the hypothalamus acts as the control centre, responding to hunger and fullness signals from the body.
Real World
Pharmaceutical companies developing obesity drugs such as Ozempic (semaglutide) target the same hormonal pathways — mimicking leptin and GLP-1 satiety signals to reduce hunger and caloric intake.
Exam Focus
Name both hypothalamic regions (LH and VMH) with their specific roles; confusing hunger and satiety centres loses marks.
