24 HOUR NUTRITION: MELATONIN is made from TRYPTOPHAN in the brain in a special area called the Master Clock in response to light and dark. At night, when you should be in darkness and sleeping, your melatonin increases in the middle of the night. Melatonin can be measured in the blood and acts a hormone signal to biological clocks in different organs in the body such as the kidneys and liver. As morning comes, the melatonin falls and another hormone called Cortisol from the adrenal gland goes up. It rises in the morning and increases your energy and ability to perform activities. In the late afternoon, around 4 or 5 PM, the Cortisol decreases and you feel tired. This is a great time for an afternoon protein-Rich shake or snack to increase your mental and physical energy. After dinner at about 7 PM, the Cortisol stays low and Melatonin made from tryptophan in your meal starts to go up. This makes you tired and ready for sleep. As people get older, the amount of Melatonin released during sleep goes down and older people typically sleep less well and sleep fewer hours. They may need more Melatonin as a supplement or made from Tryptophan. Having a protein-Rich shake with Tryptophan in the evening at dinner can help get you ready for sleep. If you are craving snack foods high in fat and sugar after dinner, have a Protein-Rich shake with tryptophan instead. Eating is a signal to your Master Clock especially when meals have protein and Tryptophan. Next time, I will review how to keep meals, snacks, and exercise timing according to your Master Clock in the brain and your Melatonin signals!! #drdavidheber #sleep #melatonin #cortisol #fatigue #tryptophan #protein to learn more go to www.drdavidheber.com and www.herbalifenutritioninstitute.com
