Eating disorders Why certain individuals continue to eat despite obesity is now being questioned as a behavioural disorder. Other factors, which would determine eating patterns, depend on availability and attractiveness of food and physiological indicators of hunger and satiety. The emotional factor may determine these, and may trigger or modulate the control of food intake. Chemicals like serotonin have emerged as key mediators determining food intake. These are known to affect the receptors in the hypothalamus in the brain, which primarily controls appetite. Based on the current information about these neurotransmitters, research is being aimed to evolve substances, which would influence the appetite centres. However till date, only a few drugs have been introduced in the market. Their usefulness and safety continue to be debatable. Most endocrinologists feel that these are rather desperate methods. Nevertheless a wide area of research is still open and what mediates hunger and satiety and why some achieve satiety with small amounts of food is a million-dollar question.
