People might experience food cravings seemingly out of nowhere, or they may be related to seeing, smelling, or hearing about a specific food. For instance, seeing an advertisement for chocolate might trigger a craving for it.

The brain regions responsible for memory, pleasure, and reward play a role in food cravings. An imbalance of hormones, such as leptin and serotonin, could also lead to food cravings.

Cravings also involve the appetite centers of the brain, even though they tend to be separate from hunger.

Various factors can affect a person’s food cravings. In people who menstruate, hormonal fluctuations across the menstrual cycle can create food cravings.

People can experience especially strong cravings during pregnancy due to hormonal changes. A person may also experience pica, which is a craving for nonfood items, such as chalk, dirt, coins, or ice chips.

Emotions can also contribute to food cravings, such as in cases of comfort eating. It is also possible that some food cravings may be related to specific foods because the body needs particular nutrients.

There are two types of food cravings: selective and nonselective.

Selective cravings are cravings for specific foods, such as a person’s favorite chocolate bar, a particular burger from their favorite restaurant, or a bag of potato chips of a certain flavor.

Nonselective hunger is the desire to eat anything. It may be the result of real hunger and hunger pangs, but it can also be a sign of thirst. Drinking water may help with intense nonselective cravings.

How to reduce cravings
There are a variety of ways to reduce unwanted food cravings. People can try the following techniques:

Reduce stress levels
Stress and emotional eating can influence a variety of health issues. Feeling stressed may promote emotional eating and cravings for comfort foods.

For example, a 2015 Source found that chronic stress was related to more food cravings and that this led to a higher body mass index (BMI) in participants.

Stress may also cause weight gain even without food cravings. Stress results in higher levels of cortisol, a stress hormone, which may promote abdominal fat.

Get enough sleep
Source found that not getting enough sleep could alter the body’s hormonal balance. This imbalance may contribute to overeating and weight gain.

Eat enough protein
A healthful diet should contain plenty of lean sources of protein, as they may help reduce cravings.

For example, the results of a 2020 review of animal studies suggest that eating protein can suppress appetite and reduce ghrelin, a hormone related to appetite.

Chew gum
Chewing gum keeps the mouth busy and may help reduce both sweet and salty cravings. Source found a small but significant difference in sweet and salty snack consumption between people who chewed gum and those who did not.

Those who chewed gum rated themselves less hungry, had fewer cravings for snacks, and felt fuller than those who did not chew gum.

Change the scenery
Some food cravings may be due to long-term habits, which can be difficult to replace. For instance, if someone gets fast food on their way home from work every day, this journey may cause cravings.

In situations such as these, people can try to form new habits. Doing this might be as straightforward as trying a new route home from work or stopping at the park for a quick walk instead of stopping to pick up fast food.

For cravings at home, it may help to take a walk around the block, take a shower, or even call a friend. These activities may help distract a person from their craving for long enough for it to subside.

Avoid hunger
Strong feelings of hunger may lead a person to crave more calorie-dense foods, such as processed or fried foods. Eating when hunger begins can help curb these cravings.

Maintaining a regular eating pattern, such as eating several small meals throughout the day, may help some people avoid hunger-induced cravings.
