Salt On Keto: Friend Or Foe?

Salt is often vilified in the health and wellness space, but is it really that bad for you? The answer is more nuanced than a simple yes or no. While it's true that excessive salt intake can lead to negative health outcomes, it's important to understand that salt is also an essential mineral that our bodies need to function properly. When following a keto diet, it is particularly important to ensure adequate salt intake, as the diet's low-carb nature can lead to a reduction in insulin, which in turn triggers the kidneys to excrete more sodium. This can result in dehydration, headaches, and fatigue if not properly managed. So, while salt may be okay for those on a keto diet, it's crucial to monitor your intake and ensure it aligns with your individual needs and health status.

Salt is important for keto dieters to avoid dehydration and fatigue

The keto diet is a low-carb, high-fat diet. When you eat low-carb, you produce far less insulin. Low, stable insulin tells your kidneys to start excreting sodium, along with extra water that was being used for carb stores. That's why bloating goes down so dramatically in the first couple of weeks on a low-carb diet. But if you aren't replenishing all the sodium your kidneys pump out, you can end up dehydrated, with headaches and fatigue.

So if you're on a keto diet, it's important to season your food generously with salt. You might also want to start your morning by drinking a big glass of water with 1 teaspoon of potassium salt and 1/2-1 teaspoon of sea salt. This will make your kidneys happy and ease cortisol production, which can help you keep your energy levels stable throughout the day.

The maximum level of sodium currently recommended by experts is 2,300 milligrams, but one study concluded that the right level of sodium for most people is between 2,500 and 6,000 milligrams per day. If you're eating a diet high in quality, whole foods, you're automatically consuming less sodium than most people who eat a standard American diet. If you're using high-quality sea salt on already flavorful food, it's unlikely that you'll overdo it.

It's also important to note that the kind of salt you eat matters. Most high-quality sea salt or mined pink Himalayan salt naturally contains about 80 trace minerals, including potassium, calcium, magnesium, iodine, iron, and zinc, among others. Quality salt is hand-mined without explosives and tested for contamination so you don't have to worry about heavy metals or pollutants.

The keto diet can increase the loss of electrolytes

When you start a ketogenic diet, you will begin to lose water, and with it, a lot of salt and other electrolytes that need to be replaced. This loss of electrolytes can lead to symptoms such as cramps, excessive thirst or hunger, headaches, fatigue, brain fog, muscle cramps, and constipation, commonly known as "keto flu".

To prevent or alleviate these symptoms, it is important to increase your sodium intake, especially during the initial days of adapting to a ketogenic diet. This can be done by salting your food to taste and consuming bone broth or bouillon. Aim for around 2 teaspoons of salt per day, which equates to about 5 grams of sodium.

In addition to sodium, other important electrolytes to track and replenish on a keto diet include potassium, magnesium, and calcium. Potassium-rich foods such as avocados, fish, beef, eggplant, and leafy greens can help maintain healthy blood pressure. Magnesium supports enzymatic reactions and plays a role in DNA replication and repair. Calcium is crucial for building bone and regulating muscle contraction and nerve impulses.

By ensuring adequate intake of these electrolytes, either through diet or supplementation, you can maintain their optimal balance in your body, allowing you to thrive and function at your best.

Sodium is an essential mineral for nerve and muscle function

Salt is often vilified in the health and wellness space, but sodium is an essential mineral for nerve and muscle function.

Sodium is a chemical element with the symbol "Na" on the periodic table. It is a crucial electrolyte that helps regulate nerve function and muscle contractions. It is also essential for maintaining the body's fluid balance and proper pH levels in the blood.

Sodium, in partnership with potassium, acts like a chemical battery that powers nerve impulses and muscle contractions. When one nerve cell needs to communicate with another, it opens channels that allow sodium to rush in. This triggers the nerve cell to fire, creating a chain reaction that carries the signal from nerve cell to nerve cell until it reaches the brain or a muscle.

Sodium also plays a vital role in regulating the body's fluid balance. It binds to water to maintain the liquid portion of the blood, helping it pass through blood vessels without increasing their size. This regulation of fluid balance is crucial for preventing dehydration and maintaining healthy blood pressure.

While sodium is essential, it is important to note that consuming too much can lead to health issues such as high blood pressure and an increased risk of heart disease. The current US dietary guidelines recommend no more than 2,300 milligrams of sodium per day for adults. However, those on the keto diet may need to consume closer to 5,000 milligrams to avoid the "keto flu" symptoms like headaches, fatigue, and constipation.

The type of salt you consume also matters. Unprocessed salts like Himalayan Sea Salt or Celtic Sea Salt are recommended over highly processed table salt, which often contains anti-caking agents.

Insulin resistance can be triggered by a low-salt diet

Salt is an essential mineral required by the body to function properly. It helps regulate nerves, muscles, and blood pressure. While following a keto diet, it is common to lose a lot of water, along with salt and other electrolytes that need to be replaced. The keto diet is infamous for its high-fat requirement, but most people tend to consume too much protein and fats, preventing their bodies from ever reaching ketosis. Another common mistake is not consuming enough salt. Not consuming enough salt can lead to "keto flu" symptoms like headaches, fatigue, and constipation.

The effects of a low-salt diet on insulin resistance are not entirely clear, and existing studies present inconsistent findings. Some studies have shown that low salt intake can increase insulin resistance by reducing body water content and increasing epinephrine, renin, and angiotensin levels, which inhibit insulin action. On the other hand, other studies suggest that low salt intake can decrease insulin resistance by lowering blood leptin levels, reducing abdominal fat cells, and regulating the expression of glucose transporter type-4 (GLUT4) and insulin receptors in fat cells.

It is important to note that the impact of salt intake on insulin resistance may vary depending on individual factors such as genetic variations, pre-existing conditions, and total energy consumption. Therefore, additional randomized controlled trials with adequate study periods and reasonable levels of low salt intake are needed to fully understand the relationship between low salt intake and insulin resistance.

The right level of sodium for most people is between 2,500 and 6,000 milligrams per day

Salt is an essential mineral that our bodies need to function properly. Sodium, the main component of salt, acts like an electrical current in our nerves and muscles, telling them to contract and communicate when needed. It also binds to water to keep the liquid portion of our blood intact, allowing it to pass through our blood vessels without increasing their size.

When following a keto diet, it is especially important to ensure adequate salt intake. This is because a keto diet naturally leads to lower insulin levels, which signal the kidneys to excrete sodium along with extra water. As a result, not consuming enough salt on a keto diet can lead to dehydration, headaches, and fatigue. To avoid these issues, it is recommended to salt your food to taste and even increase your salt intake, especially if you are experiencing any symptoms of salt deficiency.

It is worth noting that the quality of salt matters. High-quality sea salt or mined pink Himalayan salt naturally contains various trace minerals, including potassium, calcium, magnesium, iodine, iron, and zinc. On the other hand, refined table salt is highly processed and does not offer the same nutritional benefits.
