When you\u2019re full after a big meal but still reach for a bag of chips or a box of cookies, you might blame it on a lack of willpower. But a new study<\/a> suggests it could be due to how your brain responds to snacks, whether or not you\u2019re hungry.<\/p>\n

In the study, published in the journal \u201cAppetite\u201d in March 2026, researchers measured people\u2019s brainwaves after eating and found that despite being full, they still responded to tempting food cues, such as chips, chocolate and popcorn.<\/p>\n

\u201cCues are huge,\u201d Thomas Sambrook<\/a>, the study\u2019s lead author and a psychology lecturer at the University of East Anglia in Norwich, England, told HuffPost.<\/p>\n

We live in an environment where \u201cwe are bombarded with signals that indicate the nearby availability of tasty food that\u2019s going to make us happy momentarily,\u201d he said, and the brain may respond to this constant exposure by forming habits that tell you to eat when you\u2019re not hungry.<\/p>\n

So does that mean snacking is an automatic brain response that\u2019s beyond your control? Here\u2019s what to know about why we snack and how to break over-snacking habits.<\/p>\n

What happens in the brain when you snack? <\/p>\n

In the study, electroencephalogram (EEG) brain scans monitored 76 hungry people as they played a reward-based game with savory and sweet foods, including cheese-flavored chips, marshmallows, fruit cocktail and rice cakes.<\/p>\n

They were given a meal of one of the foods halfway through and encouraged to eat until they were full. Afterward, when they were shown images of foods that they said they didn\u2019t want, the areas of the brain associated with rewards continued to respond.<\/p>\n

\u201cIt doesn\u2019t matter how sick you are of the food, the brain responds with a reward signal when you see a cue,\u201d Sambrook said.<\/p>\n

The brain is \u201chighly sensitive to food images,\u201d Jessica Higgins<\/a>, a registered dietitian in the Lifestyle Medicine Program at NYC Health + Hospitals\/Woodhull, told HuffPost.<\/p>\n

\"ResearchersResearchers measured people\u2019s brainwaves after eating and found that despite being full, they still responded to tempting food cues.<\/p>\n

She said the latest study adds to other research<\/a> showing that what causes you to snack \u201coften has little to do with true hunger,\u201d and may include \u201cwhere we are, who we\u2019re with, our emotions, what types of foods are available around us, and food advertisements.\u201d<\/p>\n

Does this mean snacking is beyond your control? <\/p>\n

The desire or urge to snack may be \u201cquick and automatic, so it may seem like you\u2019re out of control, but control still exists,\u201d Theresa Gentile<\/a>, a spokesperson for the Academy of Nutrition and Dietetics, told HuffPost. <\/p>\n

\u201cI spend a lot of time helping my clients build new habits so eating well feels easier and doesn\u2019t rely on willpower alone,\u201d she said. <\/p>\n

This often involves reshaping their environments to avoid cues that trigger the urge to snack \u2014 for instance, by avoiding a work breakroom full of junk food, Gentile explained. <\/p>\n

You may not have control over how your brain responds to seeing food, but you can control whether you eat it, Higgins said. Recognize what entices you to snack (such as food ads, stress or social pressure), focus on what you can control (the foods you buy), the meals you eat during the day, and your body\u2019s hunger and fullness cues. <\/p>\n

The benefits and drawbacks of snacking <\/p>\n

Snacking isn\u2019t always a negative thing. Gentile said it can be an opportunity to fill nutrition gaps when it\u2019s not possible to meet your nutritional requirements in three meals a day. <\/p>\n

\u201cSnacks, especially if healthful, also fuel us during long periods of time in between meals,\u201d she said.<\/p>\n

The downside is that people often turn to junk food, which lacks nutrition and typically contains excess sugar and fat, Gentile said. These foods tend to be \u201chyperpalatable,\u201d meaning they\u2019re hard to stop eating, and pack in extra calories in small portions, Higgins added. <\/p>\n

People also tend to snack out of boredom, which can reinforce unhealthy habits and lead to overeating, Gentile said. Snacking also isn\u2019t a good idea if it causes you to skip nutritious meals, Higgins added. <\/p>\n

What to do when you struggle with snacking self-control<\/p>\n

When you respond to a food cue, you\u2019re creating an association that becomes a habit, Sambrook said, adding, \u201cBut every time you don\u2019t engage in habitual behavior, you weaken that association and de-automatize it.\u201d<\/p>\n

So, breaking a snacking habit starts with avoiding the cues, he said. <\/p>\n

But that can be easier said than done. Here are some tips to avoid over-snacking: <\/p>\n

Eat enough throughout the day. Over-restriction or skipping meals can encourage snacking, Higgins said. Eating balanced meals that include a mix of protein, whole grains, fruits, vegetables and healthy fats will help you manage hunger, cravings, energy and mood. Put friction between you and the snack. For instance, Gentile said to avoid activities associated with snacking, like mindless phone scrolling or TV watching. Make it more difficult to access unhealthy foods, such as by deleting food delivery apps or keeping these items out of your pantry.Change your environment. Gentile said to go for a walk after lunch if you usually grab something sweet: \u201cThis clears your mind and gives your brain time to get the \u2018I\u2019m full\u2019 signal.\u201dPay attention to how you feel while snacking. If you snack when you\u2019re not truly hungry, Higgins said to consider whether you\u2019re stressed, distracted or bored. This often triggers mindless snacking. Ultimately, get to know your hunger and fullness signals, Gentile added. <\/p>\n

How to embrace healthy snacking <\/p>\n

All foods can fit into a healthy eating pattern, including snacks, Higgins said. If you need help scheduling snacks, exploring your relationship with food, or identifying the best foods to meet your needs, she suggested seeking advice from a registered dietitian. <\/p>\n

\u201cHealthy snacking is about balance, timing, and choosing nutritious foods,\u201d she said. It can help you increase your intake of fruits, vegetables, healthy proteins and fats, and whole grains. For example, some healthy snacks include fruit and nuts, popcorn, roasted chickpeas or edamame, veggies with hummus or guacamole, or whole wheat toast with peanut butter. <\/p>\n

Overall, keep healthier foods visible and easy to grab, and less nutritious options out of sight, Gentile said. \u201cAt the end of the day, your environment matters,\u201d Gentile added. \u201cIf you come home starving and a bag of chips is sitting right in front of you, chances are you\u2019ll reach for it.\u201d <\/p>\n","protected":false},"excerpt":{"rendered":"When you\u2019re full after a big meal but still reach for a bag of chips or a box…\n","protected":false},"author":2,"featured_media":617952,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[34],"tags":[97,269,141405],"class_list":["post-617951","post","type-post","status-publish","format-standard","has-post-thumbnail","category-health","tag-health","tag-nutrition","tag-snacking"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/posts\/617951","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/comments?post=617951"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/posts\/617951\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/media\/617952"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/media?parent=617951"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/categories?post=617951"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/tags?post=617951"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
