Dieting is often associated with feelings of anger and irritability, commonly referred to as being hangry. This phenomenon can be attributed to various factors, including self-control depletion, hormonal changes, and physiological effects such as low blood sugar and reduced energy levels. People on diets may experience strong cravings and feel deprived of their favorite foods, leading to irritability and mood swings. Additionally, dietary changes, such as reducing sugar, processed foods, and alcohol intake, can result in withdrawal-like symptoms, including anger and aggression. Understanding the reasons behind diet-induced anger can help individuals better manage their emotions and make informed decisions about their dietary choices and overall well-being.

What You'll Learn

Self-control and aggression
Dieting can be challenging, and it's not uncommon for people to experience irritability and aggression while trying to control their food intake. This phenomenon has been explored by researchers David Gal and Wendy Liu, who found that exerting self-control can make individuals more prone to acting aggressively towards others. This effect is not limited to dieting but can also be observed in other forms of self-control.
Their research suggests that self-control is a finite resource. When individuals consistently make healthy choices, such as opting for carrots over cupcakes, they deplete their self-control reserves. As a result, they become less capable of managing their anger or aggression when it arises, leading to "dieting-induced anger." This anger can manifest in various ways, from punching holes in walls to lashing out at loved ones.
One way to understand this phenomenon is through the lens of inhibitory control. Inhibitory control refers to the ability to resist prepotent impulses and desires. Individuals with poor inhibitory control tend to have lower success rates with dieting. They are more likely to give in to their food cravings and may struggle with weight loss. On the other hand, those with strong inhibitory control are better equipped to resist unhealthy food desires and tend to have better long-term weight loss outcomes.
Additionally, dieting can be challenging due to the emotional connection many people have with food. Food is often used as a coping mechanism, and when individuals restrict their intake or cut out certain food groups, it can trigger withdrawal-like symptoms. This can lead to feelings of irritability and aggression as the body adjusts to the new diet.
To manage dieting-induced anger, some individuals have found it helpful to incorporate enjoyable foods into their diet in moderation or find healthier alternatives to their favorite treats. Practicing mindfulness and meditation techniques can also help individuals become more aware of their emotions and make conscious choices rather than reacting blindly. Additionally, easing into a new diet gradually, rather than making drastic changes all at once, can give the body and mind time to adjust and reduce the intensity of anger responses.

Hormones released from fat breakdown
Dieting can lead to aggression and irritability, and this may be caused by several factors, including the exertion of self-control, low blood sugar, or hormonal changes due to fat breakdown.
It is important to note that hormones are stored in fat, and when this fat is broken down, these hormones are released. For instance, leptin is a hormone produced by fat cells that reduces appetite and controls body fat storage. People with obesity tend to have higher levels of leptin but are less sensitive to its effects, resulting in a reduced feeling of fullness after meals. Insulin, another hormone, regulates carbohydrates and fat metabolism, influencing glucose uptake by tissues. Obesity is also associated with increased oestrogen production, which can elevate the risk of breast cancer in older women. Furthermore, fat distribution impacts health risks, with abdominal fat being a higher risk factor for diseases like heart disease, stroke, and arthritis than fat stored in other areas. Oestrogens and androgens influence body fat distribution, with changes in sex hormone levels affecting fat storage patterns over time.
The breakdown of fat can potentially release hormones that impact mood and anger. For example, abnormal thyroid hormone levels are linked to anxiety, irritability, and mood swings. Cortisol, the body's primary stress hormone, can also influence anger and aggression. Additionally, testosterone deficiencies or excesses can contribute to irritability and aggression, with low testosterone associated with higher cortisol levels.
While hormonal imbalances can contribute to anger and irritability during dieting, it is important to consult a healthcare professional for personalized advice and support. They can provide guidance on managing weight loss, hormonal changes, and any associated emotional challenges.

Withdrawal symptoms
Dieting can lead to a range of unpleasant withdrawal symptoms, including anger, irritability, and mood swings. These symptoms can be challenging to manage and may negatively impact an individual's well-being and social life. While the exact causes of these symptoms are complex and vary from person to person, several factors contribute to the development of withdrawal symptoms during dieting.
One factor is the reduction in calorie intake, which can lead to physical and psychological changes. The body reacts to the relative lack of calories, resulting in decreased energy levels and changes in hormone levels. This can manifest as headaches, fatigue, and irritability. Additionally, the brain, being dependent on glucose for energy, may experience altered functioning, further contributing to mood changes.
Another factor is the restriction of certain foods or food groups. Giving up favourite foods or indulgences can be difficult and lead to feelings of deprivation and cravings. The thought of being deprived of desired foods can make individuals snappy and irritable. This is especially true when dieting limits social activities, such as enjoying cocktails and appetizers with colleagues or indulging in birthday cake at a party.
Furthermore, the act of dieting requires self-control, and research has linked the exertion of self-control to increased aggression and irritability. The constant effort to make healthy choices and resist temptations can deplete one's self-control resources, making it more challenging to manage emotions effectively. This may result in unexpected anger or aggression directed at oneself or others.
Additionally, hormonal changes may play a role in withdrawal symptoms. Some hormones are stored in fat, and when that fat is broken down during weight loss, these hormones are released, potentially influencing mood and emotional regulation. This can lead to transient anger or mood swings until the body adjusts to the new hormone levels.
Lastly, the process of dieting and weight loss can be emotionally challenging. Individuals may experience a range of emotions, including frustration, disappointment, and sadness, as they navigate their new dietary patterns. It is essential to acknowledge and address these emotions healthily to prevent them from intensifying or leading to disordered eating patterns.
Understanding the potential causes of withdrawal symptoms during dieting is the first step toward effectively managing them. It is crucial to remember that dieting does not have to be an all-or-nothing endeavour. Allowing oneself to indulge in cravings occasionally or making lower-calorie versions of favourite treats can help ease the intensity of withdrawal symptoms. Additionally, practising mindfulness and meditation techniques can help improve one's ability to manage emotions and cravings healthily.

Blood sugar and energy levels
Dieting can cause changes in your blood sugar levels and energy levels, which can contribute to feelings of anger and irritability. When you skip meals or reduce your calorie intake, your blood sugar levels can drop. This can lead to symptoms such as headaches, fatigue, and irritability. Maintaining stable blood sugar levels is crucial for optimal body functioning. Low blood sugar can make you feel "hangry," a combination of hungry and angry. This state can impair your ability to control your emotions and increase your susceptibility to anger.
Additionally, dieting can result in decreased energy levels. Food is our primary source of energy, and when we restrict our calorie intake, our bodies may not receive the necessary fuel to function properly. This can lead to feelings of fatigue and exhaustion, which can contribute to irritability and a shorter temper. It is important to ensure that you are still consuming enough calories and nutrients to maintain adequate energy levels.
The impact of dieting on blood sugar and energy levels can vary depending on the type of diet and individual factors. Some diets may be more restrictive than others, leading to more significant fluctuations in blood sugar and energy levels. It is crucial to consult a healthcare professional or a nutritionist before starting any diet to ensure that it is well-balanced and meets your individual needs. They can provide guidance on how to manage your blood sugar and energy levels while dieting.
To mitigate the effects of dieting on your blood sugar and energy levels, there are several strategies you can implement. Firstly, avoid skipping meals. Ensure that you are consuming regular, balanced meals to maintain stable blood sugar levels. Include complex carbohydrates, lean proteins, healthy fats, and plenty of fruits and vegetables in your diet. These provide a steady release of energy and help prevent drastic drops in blood sugar.
Secondly, be mindful of your calorie intake. While creating a calorie deficit is often necessary for weight loss, ensure that you are not restricting your intake too severely. Aim for a moderate calorie deficit that still provides your body with the energy it needs to function optimally. You can use calorie calculators and consult with a nutritionist to determine an appropriate calorie range for your goals and body.
Lastly, listen to your body and be flexible. If you find that your diet is consistently leaving you feeling irritable, tired, or hungry, make adjustments. Consider increasing your calorie intake slightly or adding more enjoyable foods to your diet. Remember that dieting does not have to be about deprivation; finding a balance that works for your physical and mental well-being is essential. By prioritizing blood sugar stability and adequate energy levels, you can help reduce the chances of dieting making you angry.

Social life limitations
Dieting can impact an individual's social life in several ways. Firstly, dieting often involves limiting food intake, which can lead to hunger pangs, headaches, and low energy levels. These physical symptoms can make it challenging to engage in social activities that require physical stamina or prolonged periods of socializing. Individuals on a diet may find themselves fatigued more quickly and may not have the energy to participate in social events or maintain their usual social routines.
Secondly, dieting can induce irritability and mood changes. The restriction of certain foods or reduction in overall calorie intake can affect the levels of "happy chemicals" in the brain, leading to feelings of anger, stress, and irritation. This can make individuals more prone to lashing out at others or experiencing social anxiety in situations where they would usually feel comfortable. Social gatherings often involve food and drinks, and individuals on a diet may feel self-conscious or pressured to explain their dietary choices, potentially leading to uncomfortable conversations or feelings of isolation.
Additionally, dieting can become all-consuming and obsessive for some people. The constant focus on food, calorie counting, and meal planning can leave little room for social engagement or enjoyment of social activities. Individuals may find themselves constantly worrying about what they can or cannot eat, making it difficult to relax and fully engage in social situations. This preoccupation with dieting can strain relationships and lead to social isolation if individuals feel they cannot participate in social activities that involve food or drinks.
Furthermore, dieting and weight loss can attract unwanted attention and comments from others, particularly in social settings. Individuals who have lost a noticeable amount of weight may become the target of excessive scrutiny, praise, or criticism regarding their bodies. This can lead to feelings of self-consciousness and discomfort in social situations, causing individuals to avoid social gatherings or engage in protective behaviours, such as wearing baggy clothes to avoid attention.
Lastly, dieting often involves making significant changes to one's eating habits and food choices. This can lead to feelings of deprivation and a sense of missing out on enjoyable social experiences. Social gatherings are often centred around food and drinks, and individuals on a strict diet may feel limited in their options or worried about deviating from their diet. This can result in a sense of social isolation and a feeling of being an "island," separate from their usual social circle. However, it is important to note that dieting does not have to be a barrier to social engagement. Individuals can make conscious choices, such as opting for low-calorie drinks or practising portion control, to enjoy social events without compromising their dietary goals.
