To start is important to understand two key concepts, what do hunger and satiety?
Satiety is the opposite of hunger, ie, is the feeling of fullness or completeness. It is accompanied by positive feelings and calm, good mood, sleepiness, etc.. This is reflected in the popular saying “a full stomach, happy heart.”
Contrary to this feeling is hunger that drives you to search for food and is accompanied by unpleasant sensations such as irritability, aggressiveness, tremors, weakness and emptiness in the stomach.
We know the brain is involved in regulating our appetite, which has influenced the development of a variety of drugs that act on the nervous system, either by increasing the feeling of satiety as Sibutramine, increasing our metabolism as the Ephedrine and caffeine or other, not acting on nervous system, interfere with the absorption of fats in the food as is sold under the name Orlistat Xenical.
It is very important that before using any medication you should consult your doctor and know the side effects you may have.
