Appetite is controlled by the area of the brain called the hypothalamus. After a meal in the body increases the amount of insulin hormone, and leptin. They act on the hypothalamus, and it blocks appetite.
However, you can regulate appetite and without hormones - through taste buds. This is possible because brain cells tanitsitam lining the bottom of the third ventricle in the brain. Tanitsity receive information about food by taste buds on the tongue and transmit signals to the hypothalamus in its long process.
It used to be that they only respond to sweet taste. But recently, scientists have foundAmino acid sensing in hypothalamic tanycytes via umami taste receptorsThat tanitsity also activated by umami taste. This "fifth taste" that arises from the presence of amino acids in food.
The University of Warwick study, the researchers added to the highlighted brain cells concentrated amino acids. The most powerful and rapid response tanitsitov provide two essential amino acids lysine and arginine. Just 30 seconds tanitsity recognize these amino acids and transmits the information to the hypothalamus.
When you consume foods rich in arginine and lysine, taste receptors on the minds of the taste buds celebrate their presence and transmit a message to the brain. There they react tanitsity, provide signals to the hypothalamus, and reduces appetite.
Nicholas Dale (Nicholas Dale), professor of neurology at the University of Warwickamino acid levels in the blood and in the brain after a meal - a very important signals that convey a feeling of satiety. The fact that tanitsity directly feel amino acids, will help develop new ways to combat obesity.
This partly explains why people on high protein diet feel lessThe influence of higher protein intake and greater eating frequency on appetite control in overweight and obese men. hunger and not overeat, even without restrictions on calories.
Arginine and lysine are present in large quantities in foods of animal origin: beef, pork, chicken, turkey, liver, mackerel, tuna, salmon, cheese. Also, the essential amino acids contained in plant sources: Lentils, wheat germ, avocado.
If you are aiming to reduce appetite and eat less calories, try to include these foods in each meal.
