Appetite control and obesity.

Appetite has recently received the attention of researchers in developing countries due to the increasing prevalence of obesity. There are multiple complex mechanisms involved in food intake. The satiety level and the physiological state of a person are responsible for appetite expression. Specific manipulations of macronutrients have the potential to affect appetite control. Certain pharmaceutical formulations and sensitizer compounds/chemicals can also be used as appetite suppressants either orally or intravenously. Several aspects related to appetite control and obesity have been briefly reviewed in view of the current scientific and commercial trends.
