Understanding Food Cravings Based on Scientific Research

Cravings affect everyone, according to a study by Mercia Levin Pelchat of the Monell Chemical Senses Center, which indicated that nearly all young women and 70% of young males had experienced this sensation.

Clean eating isn’t for everyone, but for those who can resist the temptation, the results can be impressive. Others, including Team Shape, find it very impossible to resist these desires. So we set out to learn more about why these cravings occur and what we can do in order to alleviate this sense of emptiness and hunger.

What Do We Long For?

Before we go into why we crave certain foods, let’s take a look at some of the more prevalent ones.

  • Chocolate
  • Bread
  • Food Prepared in the Deep-Fryer
  • Sugar
  • Pizza

These are just a few of the things that many individuals crave even when they don’t feel hungry.

The body’s reaction to a lack of food is hunger. Contrastingly, compulsions have a higher cognitive component. It doesn’t matter if you’re hungry or not when they happen.

In the past, cravings were believed to be the body’s way of alerting us to a lack of nutrition. Because of this, it was common for people to think that they required a sugary treat when they were feeling low on energy. This isn’t the major reason we feel the need to binge on specific meals, but it’s not entirely incorrect either. Then sorry but this isn’t an acceptable excuse!

Let us know what you’re craving in the comments section!

What Is It About Chocolate and Women?

Let us first dispel a common misconception about why we crave certain foods.

It’s a common misconception that men and women have innately distinct food preferences. WRONG!

Only 15% of males crave chocolate, but 40% of women do, according to the Diabetes Association. Almost half of the women who said they craved chocolate said they did so more frequently when they were menstruating, which is maybe not surprising.

A study published in the “Appetite” magazine by Dr.Julia Holmes of the University of Albany concluded that there was no clear association between menstruation and desires for chocolate. As a result, the theory that premenstrual cravings are caused by a lack of particular nutrients has been disproved.

As far as I can tell, the underlying reason why women are drawn to chocolate is a combination of cultural and psychological factors. For many women in the United States, chocolate is marketed as a “guilty pleasure.” This marketing strategy has had a lasting impact on women across the country. As a result of the message, men equate chocolate cravings with womanly behavior and hence avoid it.

Women are more likely to binge when they’re feeling down, according to another preconceived gender bias. When we’re angry or upset, our cortisol levels rise, which, as when we’re stressed, makes us more hungry and, as a result, makes us want to binge eat. Stop, there are ways to avoid this roller coaster of emotions.

Why Do We Want Something?

Ancestors, how dare you!

Our ancestors are partly to blame for our desires. Apes used to subsist on sugar-rich fruit millions of years ago. Ripe fruit (which has a higher sugar content) was preferred by animals because it provided more energy. As glucose and fructose are formed from sugar, it aids in fat storage. Fructose breaks down in the body and sets in motion processes that cause fat storage to grow.

Survival in the past relied heavily on preserving fat reserves in order to avoid hunger.

Professor Richard Johnson, author of “The Sugar Fix,” says that a mutation happened during periods of hunger that allowed apes and other comparable mammals to store more fat after consuming sugars. This was a means of surviving.

For this reason, we have a hard-wired desire for sweets in our genes from our ancestors who ate high-sugar fruits.

Brain Facts: Why Do We Want What We Want?

According to the most recent findings from the Monell Chemical Senses Center, the desire sensation is linked to three different parts of the brain. All three parts of the brain’s limbic system. Cravings appear to stimulate all three of these receptors.

The hippocampus is a part of the brain.

The Hippocampus is in charge of managing the brain’s internal storage system. It is in charge of assuring us that a food is something we are familiar with and enjoy.

The Insula

It is the Insula’s reaction to physical stimuli that triggers an emotional response. To put it another way, this tells us that what we are about to eat is “happy food”.

That which is immediately preceding

Adrenaline and other opioids are released in response to the meal we recently consumed. This means that when we eat sweet or fatty meals, our bodies reward us by making us feel happy.

Research on the Monell Chemical Senses

During the one-and-a-half days leading up to their fMRI imaging session, ten healthy volunteers were only allowed to consume a nutritional supplement beverage, according to a study published in December 2004. It is possible to measure and map brain activity using the fMRI (functional magnetic resonance imaging) method.

During the fMRI sessions, the bland diet was employed to elicit cravings. In addition to the supplement, a control group was free to consume whatever they wished. They were then asked to pick a few foods they liked the most in both groups. During the fMRI scans, the names of popular cuisines and a vanilla supplement were displayed on a screen to elicit desires in the participants.

A group of people were shown a video of food and asked to imagine what it would taste like and how it would feel. Subjects were polled at the conclusion of the scan to see if they had experienced any cravings. People who just took vanilla supplement showed food cravings when envisioning the meals they liked, but not when seeing the beverage and three areas of their brain highlighted during fMRI.

As a reward center, what is its role?

The Limbic System is home to the Reward Center’s fundamental structures. In this region, the hypothalamus, amygdala and hippocampus, as well as their respective septal nuclei, are all included. For additional information on this complicated system, click here to learn more about the reward center’s components.

By recognizing a goal, the reward system creates a yearning feeling. Dopamine is released when the center is activated. In order to satisfy our cravings, we assume we will obtain pleasure through the release of dopamine in our bodies. To satisfy the yearning and abandon your healthy lifestyle, this urge suppresses the prefrontal cortex (the part of the brain that governs impulse control and long-term goal planning).

Because stress hormones cause you to feel uncomfortable, your brain tells your body that the only way for you to feel better is if you eat. As dopamine has rewarded us with a pleasant sensation, we are likely to repeat similar actions.

This is critical in terms of both evolution and ensuring one’s own survival. When food is limited and you start to get hungry, you get a good feeling when you find some food. The feeling of well-being becomes linked to the actions that brought you to the meal in the first place. You’ll want to do it again and again. Is there anything else I can do for you?

Additional Factors That Make Us Desire a Relationship


Cortisol is a hormone that our bodies create when we’re under a lot of stress or are feeling anxious. Cortisol increases blood sugar levels, which the body’s cells use for energy. It also aids in the metabolism of fat, protein, and carbohydrate. The hormones leptin and insulin are also inhibited, which leads to an increase in hunger.

The Schema for Memories

When it comes to food cravings, our memories have a lot to do with it. When you have a hunger, your body has a memory of the meal that would satisfy it. To satisfy the hunger, the food must be reminiscent of this experience. It’s almost as if our brains are telling us that the only things that will make us happy are pizza and chocolate pudding.

Cravings can turn into routines, and we may unwittingly seek for processed meals on autopilot.

Which Foods Do We Not Want To Eat?

It’s likely that you’ve now learned that you don’t seek unhealthy food due to a deficiency in a macro or vitamin, but rather because you associate that meal with euphoria. It brings you back to a time when you were full of joy and contentment.

Although our ancestry plays a role, we are ultimately responsible for the fact that we still crave things like chocolate and pizza today because of the abundance of food we have access to, and our bodies have been trained to associate indulging with a pleasant feeling, making it a habit and almost tricking our bodies into believing this is necessary for our survival like in the past.

A psychological question is: Can we teach our bodies to prefer healthy foods on their own? The answer to this question is YES.
