“Why am I always so hungry all the time?” This question is frequently asked to me by my patients who are starting a new diet, and while some people try to simply ignore it, properly managing the hunger is a lot more effective in the long run.

Let’s look at reasons why you might be so hungry, and how you can deal with it properly.

Hunger vs food cravings

Hunger and cravings are distinct but interconnected sensations related to our desire for food.

Hunger:

• Hunger is a physiological response triggered by the body’s need for sustenance and energy.
• It is a natural signal that indicates a requirement for nourishment to maintain bodily functions.
• Hunger is often accompanied by physical sensations such as growling stomach, lightheadedness, or emptiness.
• It can be satisfied by consuming a balanced meal that provides essential nutrients and calories.

Cravings:

• Cravings are psychological desires for specific types of food, often driven by factors like emotions, habits, or environmental cues.
• They are often unrelated to the body’s actual nutritional needs.
• Cravings tend to be specific, intense, and focused on certain flavors, textures, or food items.
• They can arise even when the body is not in a state of hunger and may persist even after eating.

Key Differences:

• Nature: Hunger is a physiological response related to the body’s need for sustenance, while cravings are psychological desires for specific foods.
• Source: Hunger is primarily driven by the body’s need for nutrients and energy, whereas cravings are influenced by psychological factors, such as emotions or environmental cues.
• Specificity: Hunger is a general feeling of needing food, whereas cravings are usually specific and centered around particular foods or flavors.
• Duration: Hunger is a recurring sensation that returns periodically when the body requires nourishment, while cravings can arise at any time, independent of physiological need.
• Satisfaction: Hunger can typically be satisfied by consuming a well-balanced meal, whereas satisfying cravings may not fully alleviate the desire and can sometimes lead to overconsumption.

In summary, hunger is a physiological response to the body’s need for food and nutrients, while cravings are psychological desires for specific foods driven by various factors.

Common reasons

Not enough water

The relationship between hunger and thirst is often more intertwined than we realize. Research suggests that the sensations of hunger and thirst share common pathways in the brain, leading to occasional confusion between the two signals.

Inadequate water intake can sometimes contribute to persistent feelings of hunger, leading individuals to consume excess calories unnecessarily.

• Hunger vs. Thirst: Hunger and thirst are complex physiological processes regulated by different mechanisms in the body. However, the brain regions responsible for interpreting and responding to these signals can sometimes misinterpret thirst as hunger, leading to feelings of appetite even when the body needs hydration. This misinterpretation can occur due to the shared neural circuits that process hunger and thirst, causing individuals to reach for food instead of water.
• Dehydration and Increased Appetite: Dehydration, even at mild levels, can trigger various physiological responses that impact our appetite. When the body lacks adequate water, it tries to conserve fluids, leading to a decrease in saliva production. This reduction in saliva can affect the perception of taste, making food seem less satisfying. Consequently, individuals may consume more food in an attempt to satisfy their taste buds and achieve a sense of satiety, ultimately contributing to overeating.
• Hormonal Influence: Dehydration can also disrupt the hormonal balance in our bodies, further influencing our appetite. One key hormone affected by dehydration is called vasopressin, which regulates water balance and thirst. Studies have shown that elevated levels of vasopressin can stimulate the release of another hormone called ghrelin, known as the “hunger hormone.” Increased ghrelin levels can intensify feelings of hunger and lead to a greater desire for food, even when the body primarily needs hydration.
• Decreased Metabolism: Insufficient water intake can affect the body’s metabolism, potentially leading to increased feelings of hunger. Dehydration can reduce the efficiency of cellular processes, including the breakdown of stored fat for energy. As a result, the body may send hunger signals, encouraging individuals to consume more food in an attempt to compensate for the lack of energy. This can contribute to a persistent sense of hunger despite consuming an adequate number of calories.
• Sweet Drinks: Water, coffee, and tea are good options for hydration, as they provide fluid without adding unnecessary calories. However, it is important to avoid sweet drinks, including those with artificial sweeteners, as they may stimulate an increase in overall hunger and contribute to weight gain.

Not enough protein and fat

The composition of our meals plays a significant role in determining our feelings of fullness and satisfaction. Consuming adequate amounts of protein and fat triggers the release of hormones that help regulate appetite and promote a sense of satiety.

However, insufficient protein and fat intake can leave us feeling hungry more frequently, leading to increased food consumption and potential weight gain.

• Protein and Appetite Regulation: Protein-rich foods have been shown to stimulate the release of glucagon-like peptide-1 (GLP-1), a hormone that plays a crucial role in appetite control. GLP-1 acts on the brain, signaling a decrease in appetite and promoting a feeling of fullness. When protein intake is insufficient, the release of GLP-1 may be compromised, leading to reduced satiety signals and increased feelings of hunger. Incorporating adequate protein into meals can help promote sustained fullness and reduce the frequency of unnecessary snacking or overeating.
• The Role of Fats in Satiety: Dietary fats also play a significant role in appetite regulation through the release of cholecystokinin (CCK). CCK acts on the digestive system to slow down gastric emptying, allowing for a slower release of nutrients into the bloodstream and promoting feelings of fullness. Inadequate fat intake can compromise the release of CCK, diminishing its ability to suppress appetite effectively. Including healthy fats in meals, such as those found in avocados, nuts, and seeds, can contribute to prolonged satiety and reduce the desire to eat excessively.
• Delayed Effect of Hormones: It is important to note that the hormones released in response to protein and fat consumption do not act instantaneously. It takes time for GLP-1 and CCK to exert their full effects on appetite regulation. Consequently, individuals may not feel immediate fullness after consuming protein- or fat-rich meals. Patience is key, as it can take up to 20 minutes for these hormones to signal the brain that the body is satiated. Eating slowly, chewing thoroughly, and savoring each bite allows ample time for these hormones to take effect, reducing the tendency to overeat.
• Nutritional Imbalance and Increased Hunger: A diet lacking in sufficient protein and healthy fats can lead to an imbalance in macronutrient intake, which may contribute to persistent hunger. Carbohydrates, while providing energy, are often digested more rapidly than proteins and fats, leading to quicker spikes and drops in blood sugar levels. This rapid fluctuation can result in increased feelings of hunger shortly after consuming a high-carbohydrate meal, as the body seeks additional sustenance to stabilize blood sugar. By prioritizing protein and fat intake alongside carbohydrates, individuals can achieve a more balanced and satiating meal composition.

Not enough soluble fiber

Dietary fiber plays a crucial role in our overall health and satiety. Among its various benefits, soluble fiber aids in appetite regulation by promoting feelings of fullness and satisfaction.

When the intake of soluble fiber is inadequate, individuals may experience increased hunger and a higher likelihood of overeating.

• Soluble Fiber and Satiety: Soluble fiber possesses unique properties that contribute to feelings of fullness and satisfaction. When consumed, soluble fiber absorbs water and forms a gel-like substance in the digestive system. This gel slows down the emptying of the stomach and delays the absorption of nutrients, leading to a prolonged feeling of satiety. Inadequate intake of soluble fiber can compromise this mechanism, reducing the effectiveness of stretch receptors in the stomach and potentially leading to persistent hunger.
• Stretch Receptors and Fullness: Stretch receptors located in the stomach send signals to the brain, indicating that the stomach is expanding and creating a sense of fullness. Soluble fiber plays a key role in activating these stretch receptors by providing bulk and volume to the contents of the stomach. When the intake of soluble fiber is insufficient, the stomach may not stretch adequately, diminishing the feedback signals of fullness and leaving individuals feeling hungry more frequently.
• Fiber and Water Intake: Adequate hydration is essential for the proper functioning of soluble fiber. When soluble fiber absorbs water, it expands and increases in volume, effectively promoting feelings of fullness. However, without sufficient water intake, the fiber may not bulk properly, leading to a lack of satiety. It is crucial to drink enough water when consuming soluble fiber-rich foods, such as fruits, vegetables, beans, and lentils, to ensure optimal fiber functionality and avoid potential constipation.
• Delayed Gastric Emptying: In addition to its impact on stretch receptors, soluble fiber slows down gastric emptying, resulting in a longer-lasting feeling of fullness. Insufficient soluble fiber intake can disrupt this process, leading to quicker gastric emptying and reduced satiety. Without the prolonged presence of food in the digestive system, individuals may experience increased hunger shortly after consuming a meal, contributing to more frequent snacking or overeating.

Eating too quickly or distracted

The speed at which we consume our meals and the level of attention we give to the eating process can significantly impact our feelings of hunger and satiety. Eating too quickly and engaging in distracted eating can interfere with the body’s natural mechanisms for signaling fullness, leading to increased hunger and a greater likelihood of overeating.

• Hormonal Response and Eating Pace: After a meal, our body releases hormones that promote feelings of fullness and satisfaction. However, it takes time for these hormones to be generated, released, and properly stimulate the brain. Eating too quickly shortens the timeframe for this hormonal response, potentially leading to a delay in recognizing fullness and an increased likelihood of feeling hungry soon after a meal. Slowing down the pace of eating allows the body’s satiety signals to catch up, enabling us to consume an appropriate amount of food without experiencing ongoing hunger.
• Mind-Body Connection and Satiety Signals: The act of eating is not solely a physical process; it also involves a connection between the mind and the body. By engaging in mindful eating, we heighten our awareness of the eating experience and the signals our body sends us. When we eat distractedly, such as while working or watching television, we fail to pay attention to our body’s fullness cues. Consequently, we may consume more food than necessary, as we are disconnected from the body’s natural mechanisms for regulating hunger and satiety.
• Chewing, Bites, and Portion Control: Slowing down the eating process involves mindful practices such as chewing thoroughly, taking smaller bites, and using smaller plates or bowls. Chewing each bite adequately, aiming for around 15 chews, not only aids in digestion but also allows for better recognition of fullness signals. Taking smaller bites and using smaller plates or bowls can create the illusion of larger portions, promoting a sense of satisfaction while consuming less food. These strategies help extend the duration of the meal and give the body ample time to respond to hormonal signals of fullness.
• Dedicated Time for Eating: Setting aside dedicated time for eating, free from distractions, is essential for mindful and satisfying meals. Multitasking or eating on the go can lead to a lack of focus on the eating process and hinder the mind-body connection. When we eat while working or engaging in other activities, we are more likely to override our body’s satiety signals and ignore feelings of fullness. Taking the time to sit down, relax, and fully engage with the eating experience allows us to tune into our body’s needs and respond appropriately.
• Building Healthy Eating Habits: Cultivating healthy eating habits involves adopting mindful practices and prioritizing the eating experience. Slowing down, avoiding distractions, and paying attention to the body’s fullness signals are integral to achieving satiety and preventing persistent hunger. By building a foundation of mindful eating, individuals can develop a more harmonious relationship with food, enhance their satisfaction with meals, and reduce the likelihood of overeating.

Not avoiding triggers

Our environment plays a significant role in shaping our feelings of hunger and satiety. When we are exposed to tempting stimuli like appetizing food or enticing advertisements, it can evoke strong cravings and intensify feelings of hunger.

Studies suggest that avoiding these hunger triggers is more effective than constantly resisting them, as it eliminates the constant mental effort and reduces the likelihood of succumbing to temptation.

• Psychological Influence of Temptation: The power of visual cues and food-related stimuli should not be underestimated. Simply seeing or smelling delicious food can activate our brain’s reward centers, triggering cravings and amplifying feelings of hunger. By subjecting ourselves to constant exposure to these triggers, we are more likely to succumb to temptation and engage in impulsive eating behaviors. Failing to avoid hunger triggers perpetuates the cycle of feeling hungry all the time and makes it more challenging to maintain a balanced and nutritious diet.
• Cognitive Load and Self-Control: Constantly resisting temptation places a significant cognitive load on our minds. When we are surrounded by tempting foods or engaging in activities that trigger cravings, such as late-night snacking or watching food-related content, we drain our mental resources by constantly battling the desire to indulge. This cognitive strain can lead to decision fatigue, reducing our ability to make mindful and healthy food choices. Avoiding hunger triggers alleviates this cognitive burden, allowing us to focus our energy on nourishing our bodies and making intentional eating decisions.
• Creating a Supportive Environment: Modifying our environment to support healthy eating habits is essential for long-term success. By removing or minimizing exposure to hunger triggers, we eliminate the constant source of temptation and reduce the likelihood of impulsive eating. This can be achieved by keeping tempting foods out of sight and out of the house, refraining from keeping unhealthy snacks readily available, and avoiding environments that promote mindless or excessive eating. Instead, creating an environment that encourages nutritious options and supports mindful eating can foster a sense of control over hunger and satiety.
• Mindfulness and Intentional Choices: Avoiding hunger triggers provides an opportunity to cultivate mindfulness in our eating habits. By consciously eliminating or reducing exposure to stimuli that promote excessive hunger, we can better tune in to our body’s genuine needs and make intentional choices about when, what, and how much to eat. Mindful eating involves savoring and fully experiencing the food we consume, paying attention to hunger and fullness cues, and making conscious decisions about our nutritional intake. Creating a supportive environment enables us to practice mindfulness and enhance our ability to regulate hunger and satiety effectively.
• Long-Term Benefits: Avoiding hunger triggers not only alleviates persistent hunger but also sets the stage for healthier eating patterns and long-term well-being. By proactively managing our environment, we reduce the constant struggle with temptation, allowing us to establish sustainable habits that support overall health and satiety. By avoiding hunger triggers, we empower ourselves to make choices aligned with our goals and values, ultimately leading to improved satisfaction, better appetite control, and a more balanced relationship with food.

Failing to use tools

Weight loss tools and interventions can serve as valuable aids in managing hunger and supporting overall weight management efforts. When implemented correctly and under professional guidance, tools such as nutritional supplements, vitamin injection therapies, gastric balloons, and medications can help address nutritional deficiencies, stimulate hormones, or induce a sense of fullness.

• Nutritional Deficiencies and Supplementation: Certain nutritional deficiencies can trigger cravings and persistent hunger. In such cases, targeted supplementation with vitamins, minerals, or other nutrients can help address the underlying deficiencies, leading to reduced hunger and improved satiety. Neglecting to use appropriate supplements when recommended may prolong feelings of hunger and hinder progress towards a healthier weight.
• Medications and Hormonal Regulation: Certain medications can be prescribed to stimulate the release of hormones that regulate hunger and promote a sense of fullness. These medications work by targeting specific receptors in the body to modify appetite signals. When used under medical supervision, these medications can be effective tools for appetite control and weight management. Failing to explore the potential benefits of such medications, when appropriate and prescribed by a healthcare professional, may result in continued struggles with hunger and hinder progress toward achieving a healthy weight.
• Customized Approaches and Professional Guidance: It is crucial to emphasize that the utilization of weight loss tools should be approached with professional guidance and tailored to individual needs. Working closely with healthcare professionals, including registered dietitians, nutritionists, and medical practitioners, can ensure that the right tools are employed in a safe and effective manner. These experts can assess nutritional deficiencies, evaluate medical considerations, and recommend appropriate interventions to address persistent hunger. Failing to seek professional advice and customized approaches may limit the potential benefits of weight loss tools and hinder appetite management efforts.

Medical reasons

Constant hunger can also be caused by certain medical or physiological issues. It’s important to address these issues as well.

• Not getting enough sleep: Lack of sleep can lead to increased hunger and cravings for unhealthy foods.
• Certain medications: Some medications, such as antidepressants, can cause changes in appetite and increase hunger.
• Hormonal imbalances: Hormonal imbalances, such as those that occur during pregnancy or menopause, can also affect hunger levels.
• Stress and emotions: Stress and emotions can also play a role in hunger and appetite. When we’re feeling stressed or emotional, we may turn to food as a way to cope, which can lead to increased hunger.
• Medical conditions: Certain medical conditions, such as hyperthyroidism or diabetes, can affect hunger levels. If you’re experiencing sudden changes in hunger or appetite, it’s important to speak to a healthcare provider.
