Their findings, published online and forthcoming in the October issue of Food Quality and Preference, suggest that slightly spicier meals prompted participants to eat less and consume fewer calories overall.<\/p>\n<p>\u201cWe know from previous studies that when people slow down, they eat significantly less,\u201d said Paige Cunningham, a postdoctoral researcher and lead author on the study who earned her doctorate in nutritional sciences from Penn State in 2023. \u201cWe suspected that making a meal spicier might slow people down. We thought, let\u2019s test, under controlled experimental conditions in the lab, if adding a small amount of spice, but not so much that the meal is inedible, will make people eat slower and therefore eat less.\u201d<\/p>\n<p><a href=\"https:\/\/scitechdaily.com\/images\/Spices-Poured-Into-Bowl.jpg\" rel=\"nofollow noopener\" target=\"_blank\"><img loading=\"lazy\" decoding=\"async\" class=\"size-large wp-image-496405\" src=\"https:\/\/www.newsbeep.com\/us\/wp-content\/uploads\/2025\/09\/Spices-Poured-Into-Bowl-777x583.jpg\" alt=\"Spices Poured Into Bowl\" width=\"777\" height=\"583\"  \/><\/a>Study participants tasted meals in which the spiciness level was controlled by carefully varying the ratio of hot versus sweet paprika added to the dishes to vary the heat while keeping chili flavor constant. Credit: Patrick Mansell \/ Penn State<\/p>\n<p>The researchers found that increasing spiciness slightly using dried chili pepper slowed down eating and reduced the amount of food and energy consumed at a meal, all without negatively affecting the palatability of the dish.<\/p>\n<p>Potential for Portion Control<\/p>\n<p>\u201cThis points to added chilies as a potential strategy for reducing the risk of energy overconsumption,\u201d said John Hayes, Penn State professor of food science and corresponding author on the paper. \u201cWhile portion control wasn\u2019t the explicit goal of this study, our results suggest this might work. Next time you\u2019re looking to eat a little less, try adding a blast of chilies, as it may slow you down and help you eat less.\u201d<\/p>\n<p>The team conducted three related experiments in a total of 130 adults who were served one of two lunch meals \u2014 beef chili or chicken tikka masala \u2014 in one of two versions: mild or spicy. The spiciness level was controlled by carefully varying the ratio of hot versus sweet paprika added to the dishes to vary the heat while keeping chili flavor constant.<\/p>\n<p>The researchers then recorded participants on high-definition video while they ate their meals to monitor their eating behaviors. From the videos, Hayes\u2019 team measured the amount of food and water consumed, meal duration, eating speed of grams per minute, bite rate, bite size, and collected ratings on appetite, liking, and spiciness before and after the meal.<\/p>\n<p><a href=\"https:\/\/scitechdaily.com\/images\/Paige-Cunningham.jpg\" rel=\"nofollow noopener\" target=\"_blank\"><img loading=\"lazy\" decoding=\"async\" class=\"size-large wp-image-496406\" src=\"https:\/\/www.newsbeep.com\/us\/wp-content\/uploads\/2025\/09\/Paige-Cunningham-777x583.jpg\" alt=\"Paige Cunningham\" width=\"777\" height=\"583\"  \/><\/a>A team of researchers at Penn State found that increasing spiciness slightly using dried chili pepper slowed down eating and reduced the amount of food and energy consumed at a meal, all without negatively affecting the palatability of the dish.

Credit: Patrick Mansell \/ Penn State<\/p>\n<p>\u201cFormulating the recipes took a long time for the chicken tikka,\u201d Cunningham said. \u201cIt took so many rounds of testing that my lab mates were sick of it. But science is about trial and error. I\u2019d make a recipe, see how far I could push the spiciness, and we\u2019d taste it. We did that until we reached a level where palatability was matched even when spiciness increased.\u201d<\/p>\n<p>Why Spicy Meals Reduce Intake<\/p>\n<p>The study suggests the reduction in intake is driven by changes in oral processing behaviors, she explained. Specifically, participants ate the spicier meals more slowly. She explained that a slower eating rate often means food is in the mouth longer, which can help signal fullness and lead to eating less. Other studies that slow the eating rate by manipulating texture have shown similar effects, she said.<\/p>\n<p>\u201cWhat\u2019s critical here is that the reduction in intake occurred without negatively impacting how much participants liked the food,\u201d Hayes said.<\/p>\n<p>He added that water intake didn\u2019t differ significantly between spicy and mild meals, suggesting that one seemingly obvious explanation, that people drank more water and filled up faster, was not the primary reason people ate less.<\/p>\n<p>\u201cThis is why we need to do empirical studies of behavior, because what you might intuitively expect is often not the case,\u201d he said.<\/p>\n<p>Hayes also noted that appetite ratings made before and after the meals were similar, suggesting participants still felt full after the spicy meal, despite eating less of it. Looking ahead, the team is now focused on understanding how oral burn can impact other eating behaviors, like snacking.<\/p>\n<p>Reference: \u201cIncreasing the spiciness of a lunch meal influences oral processing behaviors and decreases food and energy intake\u201d by Paige M.
