Hyper-palatable Food Only for Taste Not for Slim Waist

Researchers used previous study data to establish which meal elements were relevant in influencing how many calories were consumed. They discovered that three meal characteristics consistently related to higher calorie intake across four different dietary patterns: meal energy density (i.e., calories per gram of food), the amount of "hyper-palatable" items consumed, and the speed with which the meals were consumed. The protein level of the meals also contributed to calorie consumption, however, the impact was less consistent (1^✔ ✔Trusted Source

"We wanted to know how the hyper-palatable characteristics of foods, in combination with other factors, influenced how many calories a person consumed in a meal," said Fazzino, an assistant professor in the KU Department of Psychology and associate director of the Cofrin Logan Center for Addiction Research and Treatment at the KU Life Span Institute.

Food Hedonics: Are Food 'Liking' and 'Wanting' Viable Appetite Control Targets in Obese People?

In an environment rife with energy-dense and highly delicious foods, it appears conceivable that the hedonistic system of appetite control will play a main role in eating behavior, undermining homeostatic processes and driving consumption beyond energy requirements. The contrast between the "liking" and "wanting" components of food reward is an important topic in the hedonics of food consumption. Separate brain pathways exist to mediate these functions, and experimental behavioral approaches to distinguish and quantify them separately in humans have been devised (2^✔ ✔Trusted Source

Fazzino and colleagues from the NIH's National Institute of Diabetes and Digestive and Kidney Diseases reported in the journal Nature Food that hyper-palatability boosted energy consumption across four diet patterns: low-carbohydrate, low-fat, an unprocessed diet, and an ultra-processed diet.

Understanding how some meals cause people to eat fewer calories without feeling hungry could help guide diet recommendations for weight management. People are frequently advised to avoid energy-dense items that can contribute to passive overeating, such as cookies or cheese. Instead, meals with low energy density, such as spinach, carrots, and apples, are frequently recommended. However, hyper-palatable foods may be unfamiliar to individuals, and they may accidentally include them on their plates.

How Hyper-palatable Foods Trigger Weight Gain?

Another theory to this is when the flavors in hyper-palatable foods trigger the release of endorphins and dopamine (the feel-good chemicals in the brain), making one crave for such unhealthy food again and again, an effect that's considered similar to drug addiction

While highly palatable foods can be energy dense, the present study reveals that these highly palatable items contribute to meal calorie intake on their own. According to Fazzino, the findings add to a growing body of studies indicating that hyper-palatability influences people's eating choices and weight.

"We hope to get the information about hyper-palatable foods out there for individuals to consider as they make dietary choices, and we hope that scientists continue to examine hyper-palatable characteristics as a potential factor influencing energy intake," she said.
