One condition, gastroparesis , causes food to stay in the stomach for too long, which can affect normal hunger signals and make it difficult to eat enough. What you eat can have a large effect on your hunger and appetite levels. Foods that contain plenty of protein, fat, fibre, and complex carbohydrates tend to be more filling.
This is because they take longer to digest, keeping contents in your stomach for longer and leading to a slower release of nutrients into the blood stream. Highly processed foods, particularly those that contain lots of simple sugars, can make you feel very hungry because they lead to rapid swings in blood sugar levels. Typically, blood sugar rises quickly after eating processed foods, then drops quickly shortly after, unlike the slow sustained release of glucose from complex carbohydrates.
In addition, lifestyle factors such as exercise and stress can affect hunger and appetite. If you exercise frequently, you will likely become hungrier, as your body needs more calories and nutrients to function. However, occasional exercise might suppress appetite in some individuals. For example, being stressed, bored, depressed, or experiencing various strong emotions can change your appetite level.
In some people, heightened emotional states can lead to an increased appetite, whereas others might find it very difficult to eat anything when they are experiencing strong emotions. Medications can also affect appetite levels. In some cases, this occurs as a side effect, other times, your physician might prescribe a medication specifically to reduce or increase your appetite. Hunger and appetite are complex systems. Another study found that people who distracted themselves with a computer game during lunch were less full than those who did not play the game.
To avoid distracted eating, you can try practicing mindfulness, minimizing screen time, and silencing your electronic devices. Distracted eating may be a reason why you are always hungry, as it makes it difficult for you to recognize feelings of fullness. Individuals who exercise frequently burn a lot of calories. This is especially true if you regularly participate in high-intensity exercise or engage in physical activity for long durations, such as in marathon training.
Research has shown that those who exercise vigorously on a regular basis tend to have a faster metabolism, which means that they burn more calories at rest than those who exercise moderately or live sedentary lifestyles 34 , More recently, however, a systematic review of studies found no consistent evidence to support increased energy intake during exercise. Additional randomized studies are needed The results were similar for men Although several studies have shown exercise to be beneficial for suppressing appetite, there is some evidence that vigorous, long-term exercisers tend to have greater appetites than those who do not exercise 39 , 40 , 41 , You can prevent excessive hunger from exercise simply by eating more to fuel your workouts.
It is most helpful to increase your intake of filling foods that are high in fiber, protein, and healthy fats. Another solution is to cut back on the time you spend exercising or reduce the intensity of your workouts. Individuals who regularly exercise at a high intensity or for long durations tend to have greater appetites and faster metabolisms.
Thus, they may experience frequent hunger. Alcohol is well known for its appetite-stimulating effects Studies have shown that alcohol may inhibit hormones that reduce appetite, such as leptin, especially when it is consumed before or with meals.
For this reason, you may feel hungry often if you drink too much alcohol 43 , 44 , In one study, 12 men who drank 1.
They were also more likely to consume high amounts of high fat and salty foods Alcohol may not only make you hungrier, but it also impairs the part of your brain that controls judgment and self-control. This may lead you to eat more, regardless of how hungry you are Drinking too much alcohol may cause you to feel hungry frequently due to its role in decreasing the production of hormones that promote fullness.
If you consume a lot of liquid foods, such as smoothies , meal replacement shakes, and soups, you may be hungrier more often than you would be if you ate more solid foods. One major reason for this is that liquids pass through your stomach more quickly than solid foods do 49 , Furthermore, some studies suggest that liquid foods do not have as great of an impact on the suppression of hunger-promoting hormones, compared with solid foods 49 , Eating liquid foods also tends to take less time than eating solid foods.
In one study, people who consumed a liquid snack reported less fullness and more feelings of hunger than those who consumed a solid snack. They also consumed more calories throughout the day than the solid-snack group To prevent frequent hunger, it may help to focus on incorporating more solid, whole foods into your diet.
Liquid foods do not have the same effects on keeping you full and satisfied as solid foods do. For this reason, you may feel hungry frequently if liquids are a major part of your diet. This is mostly due to its effects on increasing levels of cortisol , a hormone that has been shown to promote hunger and food cravings. For this reason, you might find that you are always hungry if you experience frequent stress 53 , 54 , 55 , In one study, 59 women who were exposed to stress consumed more calories throughout the day and ate significantly sweeter foods than women who were not stressed Another study compared the eating habits of young girls.

While our society may have evolved to provide us with endless opportunities to eat, our bodies are primarily concerned with keeping the well-oiled machine going.
This means that we start to feel hungry once our stomach is empty. After a meal, our gastrointestinal tracts slowly empty by pushing food through the stomach and the small and large intestine. Specialized contractions called the migrating motor complex MMC sweep up undigested food, which is a process that takes around minutes. The final phase of the MMC is regulated by a hormone called motilin. Motilin-controlled contractions cause the rumbling in our stomachs and coincide with hunger pangs in humans.
Another hormone implicated in hunger control is ghrelin. In mice, ghrelin activates neurons called agouti-related peptide AgRP -expression neurons in the hypothalamus region of the brain, which tell us that we are hungry.
These neurons are the control center for hunger.
