Understanding Food Cravings: What Causes Them And How To Curb Them?

Have you ever experienced an overwhelming attraction to a certain food? It may be a bag of chips, a pizza slice, or a container of ice cream. Even though you should avoid eating it, you just can’t help yourself. This is a common food need that many of us experience.

The complicated phenomena of food cravings involves a variety of physiological, psychological, and environmental elements. This essay will examine the science underlying food cravings and offer advice on overcoming them.

What are food cravings?

Food cravings are strong appetites for particular foods. Many things, including as hunger, tension, boredom, and even specific odours or visual signals, can cause them.

Cravings are not the same as regular hunger. Unlike urges, which are more psychological in origin, hunger is a physical need for food. You can experience a rumble in your stomach or a lack of energy when you’re hungry. Even though you’re not physically hungry, you could have a strong desire for a certain cuisine if you have cravings.

Why do we get food cravings?

We get food cravings for a variety of causes. Among the most frequent causes are:

  • Nutritional deficiencies: You might crave foods high in particular nutrients if your body is deficient in certain substances. For instance, you can prefer red meat if you’re iron deficient.
  • Hormonal fluctuations: Cravings for particular foods might be brought on by hormonal changes, such as those that take place during menstruation, pregnancy, or menopause.
  • Emotional factors: Cravings for food can be triggered by stress, boredom, worry, and depression.
  • Habit: If you’re accustomed to eating a certain food at a specific time of day or in a specific environment, you can get cravings for that item when you find yourself in those circumstances again.
  • Conditioning: You might seek particular meals in the future if you’ve already been exposed to them and have favourable associations with them.

The science behind food cravings

The complicated phenomena of food cravings involves a variety of physiological, psychological, and environmental elements. Let’s examine some of the science driving cravings in more detail.


Neurotransmitters are brain molecules that assist in controlling emotions and behaviour. When we have a yearning for food, it’s frequently because particular neurotransmitters, like dopamine, have been activated. Dopamine is a neurotransmitter that makes you feel happy and is released in reaction to enjoyable experiences like enjoying a tasty meal. Dopamine is released when we eat foods we like, which makes us feel good and rewarded. We may start to seek specific foods when we’re depressed or worried because our brains eventually come to associate such foods with pleasure.

Gut-brain axis

The gut-brain axis is a sophisticated system that links the brain with the digestive system. Many neurotransmitters that are present in the brain are also produced by the millions of neurons that make up the gut. Our gut transmits messages to the brain during meals that may have an impact on our emotions, actions, and appetites. A high-carbohydrate meal, for instance, may cause your gut to create more serotonin, a neurotransmitter linked to emotions of happiness and wellbeing. Future cravings for more carbohydrates may result from this.


Conditioning is a psychological phenomena in which we come to link particular stimuli with particular actions or results. For instance, if you consistently eat chocolate cake when you’re depressed, you can start to associate it with happiness and comfort. This may cause you to crave chocolate cake whenever you’re depressed.

How to overcome food cravings?

Let’s look at some methods for conquering food cravings now that we have a better understanding of the science underlying them.

  • Identify your triggers: This may refer to particular things like persons, circumstances, feelings, or even cuisines. You can start creating methods for avoiding or controlling your triggers once you’ve recognised them.
  • Eat a balanced diet: Eating a nutritious, well-balanced diet can assist to lessen cravings. Make sure your diet is rich in fibre, healthy fats, and proteins. This may assist in keeping you satisfied and full, which may lessen the probability of cravings.
  • Stay hydrated: Keep yourself hydrated because thirst and hunger are frequently confused with dehydration. To stay hydrated, make sure you’re drinking lots of water throughout the day.
  • Practice mindfulness: Mindfulness is the skill of paying attention to your thoughts, feelings, and sensations in the present moment without passing judgement. You can become more aware of your urges and learn to resist them by engaging in mindfulness practises.
  • Find healthy substitutes: If you’re wanting a certain dish, make an effort to locate a healthy alternative. For instance, instead of reaching for a candy bar when you’re desiring something sweet, try eating a piece of fruit.
  • Get enough sleep: Sleep deprivation can boost appetites, particularly for foods heavy in carbohydrates and fat. To lessen cravings, make sure you get enough sleep each night.
  • Reduce stress: Cravings for food are frequently caused by stress. Look for stress-reduction techniques that are beneficial, like yoga, meditation, or deep breathing.

Connection Between Food Cravings and Hormones

Our hunger and cravings are significantly regulated by hormones. Particularly, the hormones ghrelin and leptin are two of the most important hormones involved in regulating appetite and satiety.

The “hunger hormone” ghrelin is frequently referred to as because it promotes food intake and boosts appetite. It is created in the stomach and tells the brain to release hunger-inducing chemicals. Before meals, ghrelin levels tend to increase, and afterward, they tend to decline.

By reducing hunger and increasing energy expenditure, leptin, on the other hand, is referred to as the “satiety hormone” and aids in the regulation of energy balance. Fat cells create leptin, which tells the brain to suppress hunger and speed up metabolism. Leptin resistance, in which the body no longer reacts to the hormone’s signals and causes increased hunger and overeating, can occur in some people.

Food cravings may result from hormonal changes, particularly during menstruation or menopause. For instance, changes in oestrogen and progesterone levels during the menstrual cycle can result in cravings for salty or sweet meals. Similar to this, lower oestrogen levels during menopause might cause cravings for high-fat and high-sugar foods.

Eating a balanced diet with regular meals and snacks, staying hydrated, and engaging in regular exercise are all effective strategies for controlling cravings brought on by hormonal shifts. Hormone replacement treatment or all-natural supplements like black cohosh or evening primrose oil may also provide comfort for some ladies.


Although food cravings are a natural part of life, they can be difficult to suppress. You can lessen the frequency and intensity of your cravings by comprehending the science underlying them and putting some of the methods we’ve discussed into practise. Just keep in mind that it’s crucial to pay attention to your body’s demands, provide it with the nutrition it requires, and manage your desires in a healthy way.
