If you’re anything like many people, thoughts about food frequently cross your mind. While every type of food has its merits, there’s an undeniable allure to sugary treats that can sometimes feel irresistible. The desire for dessert after meals can feel almost mandatory, sweets seem like an essential part of the daily diet, and snacking on sugary items becomes a regular activity.
Quelling Sugar Cravings: More Than Just Willpower
Like many others, you might not have questioned your love for sugary foods until a health concern arises. Perhaps a doctor mentioned that high sugar intake could contribute to various health problems, such as dental cavities, inflammation, diabetes, and heart disease. Armed with this knowledge, a decision to reduce sugar consumption often follows. However, controlling sugar cravings can be surprisingly challenging, revealing that it’s often more complex than simply lacking willpower.
To understand the science behind sugar cravings and discover effective ways to manage them, we consulted with health and nutrition experts: Michael Crupain, MD, MPH, a board-certified preventive medicine physician and author of the book What to Eat When; Shoshana Ungerleider, MD, an internal medicine physician, host of the TED Health Podcast, and founder of End Well; and Michael Hartman, PhD, a nutrition scientist and VP of research and development at Plexus Worldwide. Their insights shed light on the common reasons behind those intense sugar cravings and provide actionable solutions to help you regain control.
Common Reasons Behind Sugar Cravings
Sugar cravings aren’t arbitrary; they often stem from a combination of physiological and psychological factors. Understanding these root causes is the first step towards effectively managing them.
Force of Habit: The Conditioned Craving
Habit often plays a significant role in sugar cravings. According to Dr. Crupain, these cravings are frequently a result of behavioral conditioning. He explains the stimulus-behavior-reward loop: “You’ve got a stimulus, a behavior, and a reward. In the case of a sugar craving, the stimulus could be finishing dinner, the behavior is eating the sweets, and the reward is how you feel—in this case, good.”
This “feel-good” sensation is linked to dopamine, a neurotransmitter released in the brain’s reward pathways when we consume sugar. Simultaneously, insulin, the hormone regulating blood sugar, spikes. Dr. Crupain elaborates, “When we eat sugar, insulin goes up in the primitive parts of our brain that is our reward pathway. This causes an increase in dopamine release, which makes us feel good and turns our behavior of eating sugar into a habit. As a result, we learn that every time we eat a meal (or something else), if we engage in the behavior of eating sugar, we will feel good.” This repetitive cycle solidifies sugar consumption as a post-meal habit.

Sugar craving solution: To break this habit loop, Dr. Crupain recommends replacing the sugary reward with a healthier, equally pleasurable alternative. Simply removing the sweet treat can lead to intensified cravings as the brain misses the accustomed dopamine release. “Reprogram your brain” by substituting the post-dinner sugar with a pleasant activity or a non-sugary treat. Engage in enjoyable activities like talking to a friend, watching a favorite show, or taking a relaxing bath. If you still desire something to consume, opt for whole fruits – natural sources of sugar packed with fiber to mitigate sugar spikes. A cup of decaf tea or a handful of nuts can also be satisfying substitutes. Choosing high-quality sweets, free from artificial additives, can also provide satisfaction similar to lower-quality options, potentially reducing the quantity consumed.
Gut Health and Gastrointestinal Issues: The Gut-Brain Connection
Emerging research highlights the significant role of gut health in various aspects of well-being, including cravings. Hartman suggests that imbalances in gut bacteria, often referred to as poor gut health, and gastrointestinal issues can contribute to sugar cravings.
He explains, “Pathogenic gut bacteria feed on sugar as one of their nutrient sources, so that the craving is really the bacteria signaling it wants its food to multiply.” In essence, these harmful bacteria thrive on sugar and send signals to the brain, triggering cravings to ensure their food supply. Furthermore, Hartman points out, “Some studies show that an absence of certain beneficial bacteria (including Lactobacillus johnsonii) can also cause cravings, possibly through the reduction of GABA production.” GABA (gamma-aminobutyric acid) is a neurotransmitter that helps regulate mood and reduce anxiety. An imbalance in gut bacteria can affect GABA production, indirectly influencing cravings.

Sugar craving solution: Improving gut microbiome health is key to addressing cravings linked to gut imbalances. Dietary and lifestyle adjustments can naturally foster a healthier gut. Prioritize “eating to support and boost gut health” by incorporating high-fiber foods, probiotic-rich foods (such as fermented foods like yogurt, kimchi, and sauerkraut), and foods that reduce inflammation. Conversely, minimize inflammatory foods, typically processed and high in unhealthy fats and added sugars.
If lifestyle changes alone don’t alleviate gut-related sugar cravings, consulting a doctor is recommended. Similar to seeking professional advice for nutrient deficiencies, gut health issues may require medical intervention. A doctor might recommend tests to identify any overgrowth of harmful gut bacteria and guide strategies to restore a balanced gut microbiome.
Hunger Hormones: Ghrelin’s Influence
Hormones play a critical role in regulating appetite and cravings. Ghrelin, often referred to as the “hunger hormone,” is another factor that can contribute to sugar cravings. Dr. Ungerleider notes, “Research has shown that ghrelin levels increase in response to sugar intake and may contribute to the development of sugar cravings.” Studies suggest a link between sugar consumption and ghrelin levels, indicating that sugar intake might stimulate ghrelin production, potentially perpetuating a cycle of craving and consumption.
However, Dr. Ungerleider also clarifies that ghrelin is not the sole determinant of sugar cravings: “While ghrelin may play a role in regulating sugar cravings, it’s not the only factor at play.” Sugar cravings are multifaceted and influenced by a combination of hormonal, neurological, and behavioral factors.

Sugar craving solution: Maintaining a nutritious and balanced diet is crucial for managing hunger hormones and stabilizing blood sugar levels. Dr. Ungerleider advises a diet that includes a combination of complex carbohydrates, protein, and healthy fats. Fiber-rich foods like whole grains, fruits, and vegetables slow down sugar absorption into the bloodstream, preventing rapid blood sugar spikes and subsequent crashes that can trigger cravings. Protein-rich foods such as lean meats, beans, and legumes promote satiety and further stabilize blood sugar by slowing digestion. Healthy fats from sources like nuts, seeds, and avocados also contribute to blood sugar stability by slowing glucose absorption.
Low Serotonin Levels: Emotional Eating and Sugar
The link between mood and food cravings is well-established. Serotonin, a neurotransmitter vital for mood regulation, can significantly influence sugar cravings, particularly in response to emotional states. If you find yourself reaching for sugary foods during stressful or down days, low serotonin levels might be a contributing factor.
Dr. Ungerleider explains, “Low levels of the neurotransmitter serotonin have been linked to sugar cravings, as well as a variety of other symptoms such as mood disorders, anxiety, and sleep disturbances.” Serotonin plays a key role in regulating appetite, food intake, mood, and overall well-being. When serotonin levels are low, the body may crave sugar as a quick way to boost mood, albeit temporarily.

Sugar craving solution: Managing stress and anxiety through healthy, sustainable strategies can effectively curb emotional sugar cravings. Dr. Ungerleider suggests, “One strategy is regular exercise, which has been shown to improve mood and reduce stress levels. Meditation and deep breathing exercises can also be effective in reducing stress and promoting relaxation.” Engaging in physical activity and mindfulness practices can naturally boost serotonin levels and improve mood, reducing reliance on sugar for emotional comfort. Seeking support from friends, family, or mental health professionals can also provide valuable coping mechanisms for managing anxiety and stress, decreasing the likelihood of turning to unhealthy behaviors like overeating sugary foods.
Lack of Sleep: Sleep Deprivation and Cravings
Sleep plays a far more crucial role in overall health than many realize, impacting everything from cognitive function to appetite regulation. Sleep deprivation can significantly disrupt hormonal balance, leading to increased cravings, particularly for sugary foods.
Dr. Crupain emphasizes the link between sleep and cravings: “A lack of sleep is linked to overeating, especially the overconsumption of junk food.” Insufficient sleep disrupts hormones like leptin and ghrelin, which regulate satiety and hunger, respectively. Sleep deprivation often leads to decreased leptin (reducing feelings of fullness) and increased ghrelin (increasing hunger), creating a physiological drive to overeat, especially calorie-dense, sugary foods for a quick energy boost. Aiming for approximately eight hours of quality sleep per night is crucial to minimize sleep-related cravings.

Sugar craving solution: Establishing a consistent and relaxing bedtime routine is key to improving sleep quality and reducing cravings. Dr. Crupain recommends several pointers for better sleep: engage in regular exercise (but avoid intense workouts 2-3 hours before bed), limit daytime naps to under 20 minutes (especially later in the day), maintain a consistent sleep-wake schedule, and avoid phone use an hour before bedtime. If sleep problems persist, consulting a doctor is advisable to rule out conditions like insomnia and explore potential solutions, including sleep specialists or medical interventions.
Lack of Nutrients: Nutritional Deficiencies and Intense Cravings
In some cases, intense and persistent sugar cravings can signal underlying nutritional deficiencies or more complex health issues. While less common, it’s important to consider nutritional imbalances when cravings are unusually strong and difficult to manage.
Unexplained and intense sugar cravings, especially when accompanied by symptoms like dizziness without sugar intake, warrant professional evaluation. These symptoms could indicate blood sugar imbalances such as hypoglycemia. Furthermore, deficiencies in certain minerals involved in insulin regulation can also manifest as sugar cravings. For example, magnesium deficiency can impair energy production at the cellular level, leading the body to crave sugar for a quick energy source.

Sugar craving solution: Consulting a doctor or a registered dietitian nutritionist is crucial when suspecting nutritional deficiencies or underlying health issues contributing to sugar cravings. A healthcare professional can conduct assessments to identify any deficiencies, determine appropriate supplementation or dietary adjustments, and rule out or manage any underlying medical conditions. Professional guidance ensures that nutritional imbalances are addressed effectively and safely, preventing potential complications and addressing the root cause of intense sugar cravings.
What To Do When You’re Having a Sugar Craving
When a sugar craving strikes, remember that you have strategies to manage it without feeling deprived. These immediate tactics can help curb the urge and make healthier choices.
-
