How to beat overeating?
Indulging in food is a favourite pass time for many. Perhaps,we enjoy food a bit too much. So why can't we stop ourselves from consuming so much fatty and sugary food? How do we beat overeating?
When our stomach is empty,it releases a hormone called ghrelin,popularly known as the 'hunger hormone'. Ghrelin interacts in the brain with the neurotransmitter,NPY and turns on the desire to eat. Once we satisfy this desire by eating,ghrelin levels drop down and hunger subsides. Conversely,after eating,a different hormone,leptin,is released from the stomach and fat cells,and interferes with NPY,further turning off the desire to eat,and making us feel full.
But if this hunger regulation system is in place,why can't we say no to a piece of cake,or chips? In the past,as hunter - gatherers,the human body needed to take advantage of fatty and sugary meals for survival,and,as a result,they became extremely desirable. But,in today's world,we can get a high fat and sugary meal at any corner at any hour. The problem is,the instinct and desire still remains and so we struggle to stop eating these meals.
Recently,it's been discovered that the continuous intake of fat and sugar overrides the regulatory system of ghrelin and leptin. The signalling pathway is insufficient to control our new diet,and so our initial evolutionary desire now plagues our ability to choose wisely and eat healthy. It's a self - perpetuating problem. The more unhealthy food you eat,the more you desire food.
