You know the feeling: You’re hit with a wave of hunger and you start scarfing down any carb-loaded snack you can get your hands on. But after the binge, comes the regret and then, a few hours later, you feel hungry again.

It’s a vicious cycle but one most of us are familiar with. And while it may seem like a mystery, there are actually several reasons why you might find yourself craving carbs throughout the day. To get a better understanding of why this happens and how you can curb your carb cravings, we talked to registered dietitian Anna Taylor, RD.
Why we crave carbs
Carbs are one of three main fuel sources for us in our diet, alongside protein and fat. And because of this, Taylor says it’s important to remember that carbs aren’t some forbidden food.
“Carbs aren’t evil,” she says. “They play an important part in a balanced eating plan. We want carbs because they’re our body’s favorite fuel source, especially for activity and exercise.”
The important role carbs play is at the root of why we need and want carbs as part of our overall diet. But there are also specific times when certain behaviors trigger particularly heavy cravings for carbs and, according to Taylor, these are the instances we need to look out for.
Too many refined carbs
One big reason you might find yourself craving carbs is due to an intake of refined carbs, or simple sugars. Some of the most frequent examples of these are white bread, pastries, sodas and even pizza.
“When we eat too many of those refined carbs, it increases our cravings for those foods,” explains Taylor. It’s a process known as insulin response. When we consume a lot of these refined carbs, those foods are more quickly digested and absorbed into the body, causing a spike in blood sugar. That spike, in turn, triggers hunger that causes us to, yep, reach for those refined carbs again and keep the cycle going.
Too few healthy carbs and calories
Another reason you might find yourself craving carbs is that you’re consuming too few carbs to begin with. Of the three main fuels for your body — carbs, proteins and fats — carbs burn the fastest.
“Your body digests and absorbs those fuels at different rates and they all do different things for your body,” notes Taylor. “So, if you’re not including enough carbs as part of your intake, your body is going to ask for those.”
Taylor says that sometimes people just don’t get enough calories overall, too. “If you’re not eating enough at all, then you’re definitely not getting enough fuel,” she says. “Low-calorie diets or skipping meals may seem like a good idea, but it’s counterproductive because then you’re on an empty tank which can trigger more — you guessed it — cravings.”
When we eat carbs, Taylor says our body releases dopamine, a “feel-good” hormone that can operate as a sort of reward. “When we feel stressed, we have these food cravings that we attribute to a lack of willpower,” says Taylor. “But that’s not the case. It’s because eating things, especially refined carbs and simple sugars, triggers that dopamine response.”
How to curb these carb cravings
If one or more of these examples hit a little too close to home, don’t worry. There are several ways you can adjust how you eat that can curb those carb cravings without completely turning your diet or routine upside down.
Eat high-fiber carbs
To break that vicious refined carb cycle, Taylor advises adding high-fiber carbs to your diet. “High-fiber carbs are absorbed and digested more slowly, which keeps your blood sugar from spiking so quickly, minimizing hunger triggered by the insulin response.”
Some examples of high-fiber foods include:
- Whole-wheat pasta.
An additional benefit is that the slower digestion and absorption of high-fiber carbs means your body will have the fuel for longer. “This helps you feel more satisfied for a longer time, especially between meals,” Taylor notes.
She also notes the other health benefits of fiber, including feeding healthy bacteria in your gut, improving cholesterol and heart health, controlling blood sugar and helping keep you regular.
Cut out white grains and simple sugars
If you can limit those refined carbs, Taylor says, you can limit those vicious cycles. And foods made with white grains and simple sugars are a big source of refined carbs. Steer clear of things made with white flour like white bread, crackers, tortillas and even pancakes.
For simple sugars, try to limit those high-sugar items like ice cream, candy, cookies and sugar-sweetened drinks. But Taylor also warns about the added sugar in foods we don’t typically associate with those examples, like granola, cereals and yogurt.
Add lean proteins and fats
Besides making sure you’re eating the right type of carbs, including a balance of lean proteins and fats can keep you full for several hours between meals and give your body that needed fuel.
Taylor recommends what’s called the “plate method,” an approach to a full plate meal that gives you the right balance of food and fuel. The plate method calls for:
- Half your plate is reserved for non-starchy vegetables like carrots, asparagus, green beans, spinach and broccoli. Salads also count here.
- One-quarter of your plate is reserved for lean protein like eggs, tofu, poultry, fish, shellfish or even low-fat cottage cheese.
- One-quarter of your plate is reserved for some of those high-fiber carbs mentioned above. You can also include starchy veggies, like potatoes, sweet potatoes corn or peas.
“It’s a ‘Goldilocks’ approach,” says Taylor. “You get the right balance and the right amount of everything you need.”
Get the right plan from a dietitian
If you feel your fuel sources are still out of whack or you’re still not getting that calorie count quite right, consult your doctor and a dietitian. They can help walk you through plans that are best for you. We’re all different and our bodies work at different speeds. But consulting an expert who knows you and your overall health, you can work to come up with the right plan for you.
Deal with stress in a non-nutritive way
When you’re feeling stressed from work or family life, you might turn to food for that dopamine rush. Instead, advises Taylor, find a non-nutritive way to deal with that stress. “There are so many ways you can still relieve stress and get that dopamine rush that doesn’t involve unhealthy foods.”
Going for a walk, spending time in your garden or talking to a friend are just a few ways you can replace unhealthy food. Even watching television while having a hot cup of tea or listening to a podcast is a great way to unwind without relying on food.
“Find things that make your heart happy without going through your stomach first,” Taylor encourages. “A chocolate bar may temporarily relieve that stress but later on, you’ll come to regret it and be hard on yourself. That’s a perfectly human reaction, but look for replacement behaviors that release that dopamine but don’t rely on nutrition.”
