Many people try to improve nutrition by focusing only on what they eat. But how we eat can be just as important.
Eating slowly gives the body time to activate the complex biological signals that regulate hunger and satiation. When food enters the stomach, receptors are triggered to send messages to the brain that nourishment has arrived. These neurohormone messengers are sent to an array of brain areas, all of which create signals to let you know that you are full.
The catch is that this process takes time—usually 15 to 20 minutes. When meals are eaten quickly, the brain may not even register those satiation signals until after more food has been consumed than the body actually needs.
By contrast, slower eating allows these neurological signals to catch up with behavior. Studies show that people who eat slowly tend to consume fewer calories, experience better digestion, and feel satisfied longer after meals.
There is also a sensory component as well. Taste, texture, and aroma all contribute to satiety. When meals are rushed, the brain receives less of that sensory input, which can leave us feeling less satisfied even after eating.
Sometimes improving nutrition doesn’t mean changing the food itself. Just giving the brain time to sense when you’re full can make a huge difference in how meals support your overall health and wellbeing.
