But they are just so hard to resist. Ultra-processed junk foods have been designed to be as tasty and rewarding as possible. When we are exposed to media advertisements, or actual food items for example, chocolate bars in the checkout lane at grocery stores , brain activity in regions associated with reward processing increases.

This reward-related brain activity results in increased food cravings and the drive to eat, even when we are not hungry. A brain region known as the dorsolateral prefrontal cortex dlPFC helps us limit the consumption of ultra-processed foods by both decreasing activity in these reward regions to reduce food cravings and by initiating the cognitive processes needed to exert conscious control over food choices.

When using functional brain imaging to examine brain responses, neuroscientists have shown that increased activity in the dlPFC helps us control food cravings and select healthier food items by decreasing activity in the reward regions of the brain.

Conversely, when activity in the dlPFC is decreased , we have a harder time resisting the temptation of appealing junk foods and will consume more snack foods. Boosting brain plasticity makes it easier to change our habits and lifestyle. More and more evidence has shown that regular physical activity can increase prefrontal brain function and improve cognition.

These exercise-induced increases in prefrontal brain function and cognition makes it easier to regulate or limit our consumption of junk foods. And we can see the effects with as little as 20 minutes of moderate intensity exercise. I have shown that people consume less ultra-processed food such as chips or milk chocolate after 20 minutes of moderate-intensity exercise in our study, this was a brisk walk at 5.

Research has also shown that both a single session of high-intensity interval training and a week high-intensity aerobic exercise program can reduce preferences or appetite for high-calorie junk foods. Similar effects are seen when people engage in moderate aerobic exercise or strength training.

The key takeaway here is that regular exercise can reduce how much people want junk foods and improve their ability to resist the temptation of these appealing foods by improving brain function and cognition.

This makes it easier to limit the consumption of these foods to achieve healthier eating and weight loss goals. When people are stressed, the body releases a hormone called cortisol , which activates what is known as the fight-or-flight response.

When cortisol levels are high, the brain thinks it needs more fuel, resulting in increased cravings for sugary or salty ultra-processed foods. Participation in regular exercise or a single bout of exercise reduces perceived stress levels and cortisol levels.

Exercise also helps reduce unhealthy drink and food consumption when people are stressed. Stress can also impact how the brain functions.

Ever find yourself rummaging through the fridge or kitchen cabinets for that delicious, satisfying something—except nothing seems to fill that void? Maybe you know what you're craving but would have to leave the house to go and buy it, or your craving is so ambiguous that even browsing the supermarket aisles might leave you stuck.

Turns out, there's more to your hankering than just hunger. While there are several other potential reasons for sudden cravings, including a nutrient deficiency, sleep deprivation , and low blood sugar, there are healthy and satisfying snack choices you can make to quench a craving until your next meal.

When you start to feel on edge, your brain might trigger carb cravings as part of your stress response. If you're craving carbs and nothing else will do, opt for whole grains—they're rich in fiber and take longer to digest, so they'll keep you feeling full longer than simple carbs.

Plus, a sweet treat can cause a blood sugar spike and crash, leaving you feeling sluggish and moody. Reach for a piece of fruit instead. Low-fat Greek or plain yogurt with some fruit is another nutrient-packed option.

When you crave sugar, try these foods instead:. That's why stress often drives weight gain. Another reason you could be experiencing salt cravings is that your body needs sodium.

Everybody needs sodium, and research suggests that when the body is low in the nutrient, the brain triggers specific appetite signals to eat sodium. But most Americans eat more than enough sodium , to the point it can become detrimental to their health, increasing the likelihood of stroke, heart disease, and hypertension.

You can satisfy salty cravings without tacking tons of extra calories—or a surplus of sodium—onto your day. Gans recommended roasting chickpeas tossed in heart-healthy olive oil and sprinkled with herbs and salt.

We are rewarded with this choice by receiving a small burst of dopamine, making us feel happy. Keep in mind, junk food did not exist back then!

In modern times, most humans have better access to food and our lifestyle is relatively sedentary. We continue to store fat in preparation of a fast or the need for an exuberant amount of physical energy events may never come. We keep on storing and storing and storing, eating and eating and eating.

This is problematic because instead of choosing an avocado, we are now choosing a Big Mac or Ice Cream. These high fat foods are not found in nature and are out of the realm of what our bodies were meant to process.

All these processed foods trigger the same reward system in our brain that cocaine and gambling does — making it really hard to break the cycle which is why you can literally feel like a junk food junkie! Not engaging in these traditions goes against cultural norms — and can feel isolating.

And no we're not talking about becoming a junk food vegan "plant-based" doesn't always mean healthy! Instead, find recipes to check all the boxes: sweet, salty, crunchy, and creamy but are made with whole food ingredients. Have these snacks on hand and try filling up on the whole food plant-based version before assessing whether or not you still need the junk food version.

For example, if chocolate is your junk food weakness find a whole food plant-based cacao recipe that fills you up and satisfies that craving, like this dairy-free chocolate peanut butter shake.

If French fries are your junk food weakness, cut up some potatoes, blanch them, and bake on degrees until crispy.
