How Keto Affects Your Mood Over Time

The ketogenic (keto) diet is a low-carb, high-fat, moderate-protein diet that has been linked to several health benefits, including weight loss, increased energy, and improved mental health. However, the diet can be restrictive and difficult to adjust to, potentially causing side effects such as keto flu, constipation, and social isolation, which may negatively impact mood. While the keto diet may improve mood and mental well-being, the effects are not immediate and can take several weeks or months to manifest.

The keto diet may help reduce stress and improve mood

The keto diet is a low-carb, high-fat, moderate-protein diet that was originally used to help manage seizures in people with epilepsy. However, it is now widely used as a weight-loss tool. The diet can affect the brain and nervous system, and there is some evidence that it may help to improve mental health and reduce stress.

A recent study by researchers at Northumbria University in Newcastle-upon-Tyne, England, found that the keto diet may be linked to better mental and emotional health in the general population. The study compared the self-reported mental health outcomes of individuals on a ketogenic diet with those on other diets, and found that those on the keto diet reported:

• Superior mood states (calmness, contentedness, alertness)
• Reduced anxiety and depression
• Fewer feelings of stress and loneliness

These psychological benefits appeared regardless of ketone levels, suggesting that sustained dietary habits might contribute to mental well-being regardless of metabolic changes.

The keto diet may increase gamma-aminobutyric acid (GABA) levels, promoting calmness and relaxation. The diet may also influence neurotransmitters like dopamine and serotonin, which regulate mood, and the gut microbiome, which affects behaviour and stress response.

Dietary approaches to improving mental health

Before attempting the keto diet, it is important to consult healthcare providers, especially for those with complex health conditions or considering major dietary changes. A balanced, whole-food, plant-forward diet is recommended, such as the Mediterranean or DASH diets, which have more documented mental health benefits and fewer associated risks.

The keto diet may cause the keto flu, which can lead to irritability, insomnia, fatigue, headaches, and mood swings

The keto diet can cause the keto flu, which can lead to irritability, insomnia, fatigue, headaches, and mood swings. This is due to the body's transition from burning glucose to burning fat for energy. The keto flu is characterised by a range of symptoms, including:

• Brain fog
• Dehydration
• Electrolyte abnormalities
• Headaches
• Insomnia
• Irritability
• Fatigue
• Mood swings

These symptoms are usually temporary and can be managed by increasing fluid and electrolyte intake. Staying well-hydrated and consuming more salt and potassium can help alleviate the symptoms of keto flu.

The keto flu typically occurs during the initial phase of the keto diet, known as the induction phase. This is when the body is adjusting to using fat as its primary energy source instead of carbohydrates. The depletion of carbohydrates and the resulting decrease in insulin levels cause a diuretic effect, leading to dehydration and electrolyte imbalances.

It is important to note that the keto flu is not a contagious illness but rather a collection of symptoms associated with the body's transition to ketosis. The duration of the keto flu can vary, but it typically lasts for a few days to a few weeks.

While the keto flu can be an unpleasant experience, it is generally not a cause for concern. However, if the symptoms persist or become severe, it is recommended to consult a healthcare professional.

The keto diet may increase energy levels

Furthermore, the keto diet has been found to increase focus and energy in the long term. While individuals starting a low-carb diet may initially experience "keto flu" symptoms such as brain fog, tiredness, and fatigue, these side effects typically subside within a few days to a few weeks. Long-term keto dieters often report increased focus and energy levels due to their bodies adapting to burning fat for fuel instead of carbohydrates.

The keto diet may also help reduce appetite and hunger cravings, leading to sustained energy levels throughout the day. The diet's impact on hunger hormones and increased protein intake may contribute to this effect. Additionally, the ketones produced during ketosis can affect the brain, helping to reduce appetite.

Moreover, the keto diet has been found to improve various health conditions, including epilepsy, Alzheimer's disease, type 2 diabetes, and heart disease. By managing these conditions, individuals may experience increased energy levels as a result of improved overall health.

It is important to note that the transition to a keto diet can vary in difficulty, and some individuals may experience more challenges than others. The keto flu, characterised by symptoms such as stomach aches, nausea, irritability, and confusion, can occur during the transition period. However, this is usually temporary, and most people start to notice improvements in their energy levels within a few days to a few weeks.

Factors to consider

While the keto diet may increase energy levels for some individuals, it is important to consider potential challenges and side effects. The keto diet can be restrictive and challenging to follow, and it may not be suitable for everyone. Additionally, it is crucial to consult with a healthcare professional before starting the keto diet, especially for individuals with certain medical conditions or those taking medications.

The keto diet may cause tummy troubles, such as constipation and diarrhoea

The keto diet is a very high-fat, very low-carb, and moderate protein

The keto diet may cause social isolation

The keto diet is a low-carb, high-fat, moderate-protein diet that was originally used by people with epilepsy to help manage seizures. It is now widely used as a weight-loss tool. The diet is restrictive, eliminating most fruits, many vegetables, and grains. This restriction may lead to feelings of social isolation, especially if many of your social gatherings revolve around food.

Social isolation due to dietary restrictions

The keto diet is highly restrictive, eliminating most fruits, many vegetables, and grains. This restriction may lead to feelings of social isolation, especially if many of your social gatherings revolve around food. For example, if you are cooking at home more often to stick to your keto diet, you may experience some depressive episodes if you are more socially isolated as a result.

Social isolation due to preoccupation with food

The keto diet can also lead to a preoccupation and obsession with food, which can further contribute to social isolation. The restrictive nature of the diet can make it difficult to find keto-friendly options when dining out or attending social events, and the constant focus on food choices may detract from the social aspect of these gatherings.

Strategies to reduce social isolation

If you are feeling socially isolated due to the keto diet, there are several strategies you can try:

• Plan ahead: When attending social events or dining out, research the menu in advance to identify keto-friendly options.
• Bring a dish to share: If you are going to a gathering, bring a keto-friendly dish and drink to ensure you have something to eat.
• Focus on conversations: Shift the focus from food to meaningful conversations. Engage in discussions and enjoy the company of others.
• Look for keto options: Scout the table for potential keto-friendly options, and ask the server if you are unsure.
• Bring keto snacks: If the event menu is unknown, bring your own keto snacks to ensure you have something to eat.

While the keto diet can be an effective tool for weight loss and management of certain health conditions, it is important to be aware of the potential for social isolation due to the restrictive nature of the diet. By planning ahead, focusing on conversations, and making some adjustments, you can reduce feelings of social isolation and still enjoy social gatherings while following the keto diet.
