Carb-Free Keto: What's The Impact?

The keto diet is a high-fat, low-carb, and moderate-protein diet. It can be effective for weight loss and certain health conditions. On a keto diet, you cut back on carbohydrates so that your body enters a metabolic state called ketosis, where it burns fat for fuel. While it can be an effective way to lose weight and control blood sugar, it also has some potential downsides, including nutrient deficiency, liver and kidney problems, constipation, and fuzzy thinking. It's not a diet to be undertaken lightly and anyone considering it should consult a doctor and a dietitian first.

You may experience the keto flu

The keto flu is a common side effect of starting a keto diet. It happens as a result of changes to your body's balance of fluid and minerals when you begin eating very few carbs. The good news is that these symptoms are temporary and you can take steps to mitigate them.

Symptoms of the Keto Flu

• Difficulty focusing ("brain fog")
• Less energy for intense exercise
• Weakness
• Fatigue
• Dizziness
• Headaches

How to Mitigate the Keto Flu

• Drink plenty of water to stay hydrated.
• Consume extra salt, either by salting your food more than usual or by drinking a cup of salty broth.
• Be patient and allow your body time to adjust to its new way of getting energy.

Your breath may smell fruity

When you're on a keto diet, your body enters a state called ketosis, where it starts burning fat for fuel instead of carbohydrates. This process produces ketones, which are released through your breath as acetone. As a result, your breath may take on a fruity or sweet odour, almost like a decaying apple. This is sometimes referred to as "keto breath" or "fruity breath".

While this fruity breath may be off-putting, it's a sign that your body is in ketosis and burning fat effectively. However, it's important to maintain proper oral hygiene and stay hydrated to prevent bad breath caused by dry mouth.

In addition to fruity breath, there are other signs that can indicate you're in ketosis. These include increased thirst and frequent urination, initial fatigue followed by increased energy, and decreased appetite.

It's worth noting that the fruity breath odour is usually more noticeable to others than to yourself. If you're concerned about the smell, you can try increasing your water intake, practising good oral hygiene, and using breath mints or mouthwash. However, be mindful that mouthwash may contain sugar or artificial sweeteners, which can interfere with ketosis.

Remember, while the fruity breath may be an indication that your body is in ketosis, it's not the only indicator. Other factors, such as increased energy levels and reduced appetite, are also signs that your body is adapting well to the keto diet.

You may feel brain fog

The keto diet is a low-carb, high-fat, moderate-protein diet that can cause a variety of side effects, including brain fog. This is a result of your body trying to maintain normal blood sugar levels, and it can lead to difficulty focusing and a lack of energy.

The keto diet is a high-fat, moderate-protein, and very low-carbohydrate diet. Carbohydrates are the body's primary energy source, but on a strict keto diet, only 5% to 10% of energy comes from carbs. This reduction in carbs puts the body into a metabolic state called ketosis, where the liver starts breaking down stored fat into molecules called ketone bodies to be used for energy.

When you deprive your body of carbohydrates, it can lead to a state of "keto flu," which includes symptoms such as weakness, fatigue, dizziness, and headaches. Brain fog is one of the cognitive effects of the keto flu, causing difficulty focusing and a lack of mental clarity.

How to Mitigate Brain Fog

The good news is that these symptoms are temporary and can be minimized by replenishing fluids and salt. Drinking plenty of water and staying hydrated is essential, as dehydration can worsen brain fog. Additionally, consuming salty broth or increasing salt intake can help balance the body's fluid and mineral levels.

It's important to note that the transition period to ketosis can take a few days to a few weeks, and the side effects should subside as your body adapts to using fat instead of sugar for energy.

Long-Term Considerations

While the keto diet can be effective for weight loss and certain health conditions, it is highly restrictive and may not be sustainable for everyone. It's important to consult a healthcare professional before starting the keto diet, especially if you have any existing medical conditions or take medications.

Additionally, the long-term health consequences of the keto diet are not yet fully understood, and there are concerns about potential nutrient deficiencies, liver problems, kidney issues, and constipation.

Your belly may bloat

A no-carb or low-carb diet can cause your belly to bloat due to constipation and trapped gas.

Constipation

Low-carb diets are often low in fibre, which can lead to constipation. Fibre-rich foods such as whole grains, fruits, and vegetables are restricted on a no-carb diet, which can lead to digestive issues. However, this usually clears up within a few weeks as your body adjusts. You can also add some fibre to your diet by consuming watery fruits like watermelon.

Trapped Gas

A low-carb diet can also cause gas to get trapped in your digestive tract, leading to a bloated stomach and discomfort. Staying well-hydrated and ensuring adequate electrolyte intake may help reduce the severity and duration of these symptoms.

You may feel moody

Your state of mind can be negatively affected when you sharply cut down on healthy carbs that send sugar to the brain. You might feel grouchy and irritable.

A study found that people who followed low-carb diets over time had less serotonin in their brains than those who were on low-fat diets. Healthy serotonin levels help guard against anxiety and depression.

Therefore, if you are feeling moody, it may be a result of your body trying to adjust to the sudden decrease in serotonin levels. This is a normal part of the process, and it is important to be patient and give your body time to adapt.

Additionally, the keto diet is often accompanied by the "keto flu," which can include symptoms such as weakness, fatigue, dizziness, and headaches. These flu-like symptoms can further contribute to feeling moody or irritable.

To help manage mood changes, it is essential to ensure proper hydration and adequate electrolyte intake. It is also beneficial to consult a healthcare professional before starting any new diet, especially one as restrictive as the keto diet.

It is worth noting that the mood changes may be temporary as your body adjusts to the new diet. However, if the moodiness persists or becomes concerning, it may be advisable to re-evaluate your dietary choices and consider alternative approaches that better suit your individual needs.
