Some of the most common reasons for your inability to stop eating are as follows:

Hunger is a powerful urge that tries to attract your attention and keep your body from starving.

Regular meals that fill the stomach and intestines should help, but what if you're constantly hungry for more food, no matter how much you eat?

Hunger is complicated and can have many different origins, said Dr. Monique Tello, a clinical teacher at Harvard Medical School, practicing physician and director of research and academic affairs for the healthy living program at Massachusetts General Hospital.

"One is hormonal," Tello, author of "Healthy Habits for Your Heart," explained to TODAY. "People's hormones — in particular ghrelin, a gut hormone — can have a stimulating effect on the sensation of hunger and appetite."

"Other signals are psychological in nature, and these are frequently the source of people's hunger."

Medical reasons:

First and foremost, any medical difficulties must be ruled out. Anyone who is constantly hungry and is unable to gain or lose weight should consult a physician, according to Tello.

Polyphagia, or continual or excessive hunger, can be caused by a variety of factors.

Hyperthyroidism: A person's physique and metabolism are "all fired up" when the thyroid is overactive, according to Tello. Patients may feel restless, shaking, and their heart may be pounding in addition to being hungry.

Type 1 diabetes is characterized by the loss of the ability to produce insulin, resulting in the inability of the body to digest sugar. "They frequently say to me, 'I'm eating and eating,' 'I'm losing weight,' and 'I'm feeling bad,'" Tello explained. Hunger is a sign of type 2 diabetes, which occurs when the body becomes resistant to insulin.

Damage to the hypothalamus: The hypothalamus is a region of the brain that regulates appetite and satiety. If it’s injured due of a tumor or head trauma, it might produce excessive hunger and hypothalamic obesity.

According to Beth Kitchin, an assistant professor of nutrition at the University of Alabama in Birmingham, drugs like prednisone, a corticosteroid steroid often used as an anti-inflammatory or immunosuppressant prescription, can also stimulate hunger. Some hormone therapy for women going through menopause may also be effective.

She routinely asks folks who remark they’re constantly hungry whether they have begun taking any new medicines or changed their dosing.

Psychological reasons:

The problem could be in your brain if there isn't an underlying medical issue.

Given how the human digestive system functions, Kitchin believes it's fair to be hungry every three to five hours. However, both experts agreed that persistent food promotion on television and a steady stream of "food porn" on social media can encourage people to eat frequently and in large quantities.

There are also deeply rooted cultural factors, such as the concept of eating three meals plus snacks every day, according to Tello. She despises the "myth of breakfast," or the belief that individuals must eat as soon as they awake.

"The larger the stomach becomes, the more people eat." The stomach is a distensible organ that may stretch to accept vast amounts of food. If it's empty, it means you're hungry. If you have a large stomach from eating so much so often, the moment your stomach is empty, it is alerting you to eat, and you will eat more."

The condition of a person's mind might also play an influence. Stress has been linked to increased levels of ghrelin, while sleep deprivation has been linked to higher levels of the hunger hormone.

Boredom, anxiety, and melancholy can all cause people to reach for the fridge when they aren't hungry.

"I tell my patients that the more they eat, the more they desire to eat," Tello explained.

Lifestyle reasons:

The most straightforward answer to the question "Why am I always hungry?" is that you're either eating too little or exerting too much, or both.

When patients go too far with their New Year's resolutions, Kitchin frequently sees it at the start of the year.

"I can see why people are hungry when they say, 'I'm so hungry,' because I look at their food diaries." "Sometimes they just don't eat enough," she explained.

Solutions:

Make sure you're not hungry any more than you need to be: Limit your time spent watching TV and using social media. Tello advises that you try to watch your favorite shows without being exposed to commercials. She orders her groceries online to avoid being assaulted by food marketing at the supermarket.

Be truthful: Consider the following questions: "Is it true that I'm hungry? Or am I simply bored?" If it's the latter, stay away from any food temptations. Rather than self-medicating with food, get therapy for anxiety or despair.

Consider intermittent fasting: According to experts, it can help you reconnect with actual, biological hunger, make it easier to detect when you're full, provide daily structure, and stop the habit of snacking.

Going without meals for a period of time can help the stomach shrink, allowing people to eat less and experience less hunger, according to Tello.

"I know patients who only eat one meal a day and are perfectly well." "I have an aunt who never eats breakfast, doesn't become hungry until lunchtime, and she's in great shape," Kitchin continued.

Adjust the quality of your diet to feel fuller: Avoid white bread, baked products, and cereals that include processed carbohydrates and sugars. Tello suggested eating a satiating diet rich in fiber, protein, and healthy fats. Try dipping carrots in peanut butter, eating a hard-boiled egg, or eating an apple. Such decisions will keep you happier for longer.

Cucumbers, tomatoes, strawberries, grapes, and other foods that naturally contain a lot of water are more satiating than other options, even though they have fewer calories, according to Dr. Michael Greger, author of "How Not to Diet: The Groundbreaking Science of Healthy, Permanent Weight Loss."

These "higher-volume" foods take longer to consume, indicating to the brain that you're full.

Keep an eye on your alcohol consumption: Alcohol reduces inhibitions and self-control, which can lead to overeating.
