When you gather at the dinner table, do you taking just a few bites, burp, and quickly finish your meal, or do you savor every bite with small nibbles?
While we often know our eating speed instinctively, the pace at which you chew significantly affects digestion, weight management, and overall health.
“Research indicates that simply slowing down your eating rate can substantially decrease your energy intake,” says Professor Sarah Berry, a nutritionist at King’s College London.
Research shows that reducing your eating speed by just one-fifth can result in a significant 11% to 15% calorie reduction.
Conversely, those who eat quickly are at a higher risk for obesity, high blood pressure, and type 2 diabetes compared to slower eaters.
Taking your time at meals can lead to less food intake, weight loss, and better digestion—all without feelings of hunger.
“If there’s one thing I’d change about tonight’s meal, it’s to slow down,” Berry advises.
The Benefits of Eating Slowly
Unlike calorie counting or carb restrictions, eating slowly is a natural weight loss strategy that reduces the desire to overeat.
Simply put, it’s the act of chewing that signals fullness, not just the digestion process. Chewing causes your stomach to stretch and triggers your intestines to release satiety hormones—chemical signals that inform your brain when you’re satisfied.
However, these mechanisms don’t respond immediately.
“These natural processes take time,” notes Professor Ciaran Forde at Wageningen University in the Netherlands, whose research focuses on how sensory input affects eating behavior. “There’s often a delay between eating and when your brain receives fullness signals.”
This lag can create a disconnect between consumption and perceived satiety. Eating too quickly can lead to overconsumption of calories before the brain registers fullness.
“These signals may reach your brain well after you’ve indulged in that 18th cookie, leaving you uncomfortably full,” Forde explains. “By then, it’s too late.”
While we can’t speed up these biological signals, we can create space for them by slowing down our eating pace.
A significant hormone involved in satiety is GLP-1, which is mimicked in popular weight loss medications like Ozempic and Wigovy, signaling your brain that you’re full.
Research from Waseda University in Japan found that participants released more GLP-1 when chewing shredded cabbage compared to swallowing pureed cabbage.
It’s effective in curbing appetite, allowing for less food intake without additional effort. Furthermore, in a 2021 study, Forde’s team discovered that slow eaters not only felt fuller but also exhibited a stronger insulin response to meals, improving their ability to process sugars.
“The initial stage of digestion happens behind the lips, not in the stomach,” Forde explains. “The way you chew can influence how your metabolism functions and your feeling of fullness post-meal, as your body prepares to digest nutrients.”

Tips for Eating More Slowly
Eating slowly enhances feelings of fullness and optimizes your body’s metabolism. Yet, changing ingrained habits can be challenging.
For Berry, the key is mindfulness. “I often find myself distracted by the TV, which leads me to eat too quickly,” she admits. “We miss out on the family dining experience where we put down our utensils and engage in conversation.”
A simple approach is to turn off screens and enjoy meals with family. Engaging in pleasant conversation rather than focusing solely on your plate can create natural pauses in chewing.
Berry also suggests putting down your utensils between bites to help pace yourself.
Additionally, a study revealed that using chopsticks encourages smaller bites, better chewing, and overall slower eating.
Modify Your Diet
Turn off the screen, enjoy family meals, and employ chopsticks—these tactics can significantly improve your chewing habits.
Additionally, focus on making smart food choices that promote slower eating. Opting for chewier foods can naturally extend meal duration and reduce your appetite.
Forde’s research emphasizes this approach, as detailed in a popular study involving 41 healthy adults who participated in two distinct diets for two weeks.
Participants were free to eat as much as they wished, with meals designed for nutrition and taste, differing only in texture.
“We engineered the texture of these meals so that one required slower eating and the other was consumed quickly,” Forde explains.
“To our surprise, when participants weren’t given specific instructions, simply changing their meals to textured foods led them to consume an average of 370 fewer calories per day.” [with more textured food] “When they consumed soft foods, they collectively ingested around 5,200 extra calories over the two weeks. In contrast, the slow-eating diet resulted in adults losing nearly half a kilogram (1 pound) of body fat weekly.”
“These findings are significant, and we achieved this without issuing directives,” Forde states. “There were no labels or public health warnings—only the foods themselves drove the results.”
This means prioritizing crunchy meals over softer options, such as selecting crunchy rolls instead of soft buns, crispy roasted veggies over steamed ones, and grilled chicken instead of nuggets.
Forde emphasizes avoiding energy-dense, soft-textured foods and sugary drinks that you can consume quickly.
“Using excessive oil or sauce makes dishes easier to eat rapidly,” he warns. “High-fat, sweet, and creamy options can be inhaled effortlessly, leading to overconsumption. Before you know it, you’ve devoured three marshmallow tea cakes!”
