Keto's First Few Days: Energy, Cravings, And Adaptation

The keto diet is a very low-carb, high-fat, and moderate-protein diet. In the first few days of keto, you may experience a range of symptoms as your body adapts to this new way of eating. This period is often referred to as the keto flu or carb flu and can include symptoms such as fatigue, mental and physical fogginess, decreased strength and endurance, digestive issues, increased cravings, and insomnia. However, not everyone experiences these side effects, and there are strategies to alleviate them. Staying hydrated, consuming more low-carb vegetables, and gradually reducing carbs are some ways to ease the transition. Understanding what to expect in the first few days of keto can help you prepare and make informed decisions about your health and diet.

Flu-like symptoms, including headaches, fatigue, nausea, and irritability

The keto flu is characterised by a combination of carb restriction and ketosis, where the body switches from burning glucose to burning ketones for energy. This transition period can be challenging, with many people experiencing mental and physical fogginess, decreased strength and endurance, and digestive issues.

To alleviate the symptoms of the keto flu, it is recommended to:

• Drink plenty of water to stay hydrated and reduce the risk of dehydration.
• Consume electrolytes to replace lost electrolytes and maintain a healthy balance.
• Get enough sleep and avoid strenuous activities to give your body rest.
• Eat enough fat, the primary fuel source on the keto diet, to reduce cravings and keep you feeling satisfied.
• Cut out carbs slowly over time to make the transition smoother and decrease keto flu symptoms.
• Consume more low-carb vegetables, which are high in iron, manganese, and potassium, to keep your mind clear and energy levels consistent.

It is important to note that the keto diet may not be suitable for everyone, and it is always recommended to consult with a healthcare professional before starting any new diet.

Digestive issues, such as constipation and diarrhoea

If your stools remain runny after you are in ketosis, you may not be consuming enough fibre to give your bowel movements bulk. You can experience occasional constipation for the same reason.

To remedy these issues, you can try the following:

• Consume more low-carb, high-fibre vegetables. The minerals and soluble fibre in these vegetables will provide your stool with bulk while simultaneously remineralising your body.
• Stay hydrated. Drink plenty of water and minerals to bring balance back to your digestive tract.
• Practise stress-relieving methods. Stress can cause both diarrhoea and constipation. The keto diet will increase your stress levels at first, so make sure you are getting enough sleep and practising stress relief methods like meditation, yoga, and outdoor walks.

Increased thirst and frequent urination

The keto diet is a very low-carbohydrate, high-fat, and moderate-protein diet. When you start the keto diet, you will experience a transition period where your body switches from burning glucose to burning ketones for energy. This transition period is called the "keto flu" and can cause a variety of flu-like symptoms, including increased thirst and a need to urinate more frequently.

During the first few days of the keto diet, your body will rapidly burn through the glycogen stored in your muscles and liver. Glycogen is bound to water in the body, typically at a ratio of 3 grams of water for each gram of glycogen. As you burn through these stored carbs, your body will release the water that was bound to them, and you will need to urinate more often. At the same time, the rapid loss of water can make you feel much thirstier than usual.

To stay healthy and mitigate the effects of the keto flu, it is important to drink plenty of water and stay hydrated. Consuming electrolytes, such as salted food or potassium-rich, keto-friendly foods like leafy greens and avocados, can also help reduce symptoms. Additionally, it is recommended to avoid strenuous exercise during this transition period and opt for lighter activities such as walking, yoga, or leisurely biking.

The keto flu symptoms, including increased thirst and frequent urination, typically last for a few days to several weeks. However, the exact duration varies from person to person, and some individuals may experience more severe symptoms than others. It is important to listen to your body and make adjustments as needed during this transition period.

Cravings for carbohydrates and sugar

The first few days of the keto diet can be challenging, especially when it comes to managing cravings for carbohydrates and sugar. This is because your body is undergoing a significant shift in its primary fuel source, switching from glucose to ketones. The reduction in carbohydrate intake forces your body to burn ketones from fat breakdown for energy instead of glucose, its usual source.

During the initial days of the keto diet, it is common to experience intense cravings for carbohydrates and sugar. This may manifest as a desire for cookies, bread, pasta, bagels, or sweets. The cravings can be overwhelming and may lead to feelings of frustration or irritability. It is important to remember that these cravings are a normal part of the transition process as your body adjusts to a new way of eating.

To manage these cravings, it is recommended to ensure you are consuming enough fat, the primary fuel source on the keto diet. Research suggests that low-carb diets can help reduce cravings for sweets and high-carb foods over time. Additionally, gradually reducing carbohydrate intake, rather than eliminating them all at once, may help ease the transition and decrease the intensity of cravings.

Finding keto-friendly alternatives to satisfy your cravings can also be a helpful strategy. For example, if you crave something sweet, opt for keto-approved desserts or snacks that fit within your macros. Staying well-hydrated and getting adequate sleep can also help reduce cravings and improve your overall well-being during this challenging transition period.

Remember that the intensity of cravings for carbohydrates and sugar typically decreases as your body adapts to burning fat for fuel. The first few days may be the most challenging, but with time, willpower, and strategic adjustments, you can successfully navigate this period and set yourself up for long-term success on the keto diet.

Lack of energy and decreased physical performance

The keto diet can cause a lack of energy and decreased physical performance, especially in the first few days. This is due to the body's transition from using glucose (carbohydrates) to ketones (fats) as its primary source of fuel. This transition period is often referred to as the "keto adaptation" phase and typically lasts a few days but can take longer for some people.

During this time, you may experience what is known as the "keto flu," which includes symptoms such as fatigue, headaches, muscle aches, nausea, brain fog, and irritability. Your body is working hard to figure out how to function without its usual source of energy, carbohydrates. This can result in a decrease in physical performance, especially in high-intensity activities.

To combat this lack of energy, there are several strategies you can try:

• Increase salt intake: Salt helps to lower the negative side effects of getting your body fat-adapted. Try salting your food generously or adding a teaspoon of salt to a glass of water in the morning. Alternatively, opt for bone broth, which is high in sodium.
• Restrict carbohydrates: To enter ketosis, you need to deplete your body's glucose stores by restricting carbohydrates. For most people, this means limiting net carbs to less than 20 grams per day. Use a keto calculator or app to track your macros and ensure you're staying within the recommended range.
• Eat more calories: Undereating is common on the keto diet due to appetite suppression. Ensure you're eating enough calories by allowing your appetite to guide your food intake. Experiment with eating more calories to boost your energy levels.
• Eat more fat: As fat is the primary source of energy on the keto diet, ensure you're consuming enough healthy fats, such as nuts, seeds, oily fish, and healthy fats like avocado and olive oil.
• Eat regular meals: Eating at regular intervals helps the body burn fat and use it for energy. It's important to eat at least three meals a day, spread evenly throughout the day. If needed, add low-carb, high-fat snacks between meals.
• Stay hydrated: The keto diet can lead to dehydration due to the elimination of carbohydrates, which hold water and electrolytes in the body. Drink plenty of water and consider adding electrolyte supplements to your routine.
• Avoid "dirty keto": Opt for whole, unprocessed foods like high-quality proteins, low-carb vegetables, fruits, and healthy fats. Avoid processed "keto-friendly" snacks, which can be high in artificial additives and lack the nutrients your body needs.
• Supplements: Consider taking supplements such as MCT oil, BHB exogenous ketones, electrolyte supplements, and vitamin B complex to support your energy levels.
• Adjust your workout routine: If you're following a rigorous workout plan, you may need to introduce carbs back into your diet or adjust the intensity or duration of your workouts temporarily.

Remember that the keto diet is a significant change for your body, and it's normal to experience some ups and downs during the transition period. These strategies can help you manage the lack of energy and decreased physical performance that may occur in the first few days of keto.
