Why is it that it takes few seconds for our body to decide that it’s had enough water not to be thirsty, but several minutes to recognize that no more food is needed cuz it’s not hungry?
In: Biology
Other people have answered it well enough but I want to throw out some notions of what ‘hunger’ is that may help people with weight gain problems.
Youve probably heard about hunger “being in the head” and well, thats pretty much true. Hunger is not exactly a “I need food” signal, its a “im currently not digesting food” signal. Just because you FEEL hungry doesnt mean you HAVE to eat. You may well be perfectly fine and fed, and overeating can definitely cause inconsistencies to worsen.
You can often ignore hunger and it will go away after some minutes, assuming you didnt actually need to eat. This is why its also healthier to eat less more often than the massive one off meals we normally eat, AND it helps lose weight because eating little bits keeps the hunger feeling away while potentially consuming less food overall.
The receptors for hunger are all over, stomach activity, intestine activity, even just the motion of eating all provide signals for the brain to say “im eating, or im fed” and the hunger dissipates. Its completely separate from “I need food im low on stuff”
But yes, as other said, with water its almost instant and is controlled mostly by the throat. And not particularly because you need water and have replenished it.
