Keto And Urination: What's The Connection?

The keto diet is a popular, effective way to lose weight and improve health. It involves a metabolic change where the body shifts from burning carbohydrates to burning fat as its primary fuel source. This can lead to several side effects, one of which is frequent urination, especially during the initial phase of starting the diet. This is due to a combination of factors, including the depletion of glycogen (stored carbohydrates) and the diuretic effect of ketones, which are produced when the body breaks down fats for energy. Additionally, a decrease in sodium intake, which often accompanies a reduction in carbohydrate-rich processed foods, can also contribute to increased urination. While it may be annoying and concerning, this side effect is usually temporary and subsides as the body adapts to its new fuel source and normalises bathroom habits.

Glycogen flush-out

When you start a ketogenic diet, you will experience a "keto flush". This is when your body water decreases, glycogen stores shrink, and salt is expelled from the body, creating a dehydrating effect.

Glycogen is the body's stored carbohydrate and is found in the muscles and liver. It is used during exercise, with more intense exercise resulting in more glycogen being used. For every gram of stored glycogen in the body, approximately three to four grams of water are stored. When you restrict your carbohydrate intake, as with a ketogenic diet, your body turns to these stored carbohydrates for fuel, and the water is expelled as a result.

The keto flush is temporary, preventable, and reversible. To prevent it, you can supplement electrolytes such as sodium and potassium, and do strength training to retain muscle glycogen and water. The body will also adapt to the diet over time, and glycogen stores may return to normal.

To reverse the keto flush, simply consume more carbohydrates and exit ketosis. This will lead to glycogen supercompensation, where glycogen stores are filled beyond their normal levels, and you will gain a couple of kilograms of water weight.

Electrolyte imbalance

When you start a ketogenic diet, your body goes through a big metabolic change, and this can lead to a number of side effects, including an electrolyte imbalance. This is because the ketogenic diet restricts carbohydrates, which lowers insulin levels. Insulin helps your cells absorb glucose, but it also makes the kidneys hold on to sodium. With lower insulin, your kidneys start to excrete more sodium and potassium, which can lead to an electrolyte imbalance. This can cause symptoms such as:

• Sleeping difficulties
• Heart palpitations
• Increased awareness of heartbeat
• Muscle cramping or twitching at night or after exercise
• Fatigue
• Headaches
• Spasms
• Dry mouth
• Dry eyes
• General feelings of lousiness

These symptoms are often referred to as the "keto flu".

To avoid or remedy an electrolyte imbalance, you can:

• Increase your salt intake
• Drink plenty of water
• Eat potassium-rich foods
• Eat magnesium-rich foods
• Take electrolyte supplements

Dehydration

Additionally, the ketogenic diet can affect your electrolyte balance, especially sodium levels. When you drastically reduce carbs, your body excretes more sodium along with the water that was linked to the glycogen stores. This can also contribute to dehydration.

To prevent dehydration while on a ketogenic diet, it is important to drink plenty of water and replenish your electrolytes. Aim for at least 2 litres of water per day and include foods packed with potassium, magnesium, and sodium such as leafy greens, avocados, and a pinch of salt. You may also consider taking an electrolyte supplement, especially after a tough workout.

Staying hydrated and maintaining proper electrolyte balance are key to avoiding dehydration and the negative side effects that can come with it, such as the keto flu, dry mouth, increased heart rate, and increased sweat production.

It is also important to note that the ketogenic diet should be avoided by people with certain medical conditions, such as liver failure or fat metabolism disorders. Always consult with a doctor or healthcare professional before starting any new diet, especially if you have a medical condition.

Keto flu

The "keto flu" is a group of symptoms that may appear two to seven days after starting a ketogenic diet. The symptoms can range from mild to severe and vary from person to person. While some people may transition to a ketogenic diet without any side effects, others may experience a collection of flu-like symptoms, including:

• Headaches
• Fatigue
• Low energy
• Diarrhea
• Dry mouth
• Sugar cravings
• Brain fog
• Stomach or intestinal pain
• Muscle soreness
• Irritability
• Trouble sleeping
• Poor focus and concentration
• Dizziness
• Cramping

The keto flu is caused by the body adapting to a new diet consisting of very few carbohydrates. Normally, the body runs on glucose (sugar) as its main fuel source. But when you start a low-carbohydrate diet, your metabolism begins to switch over to burning fat for fuel. This switch to burning fat for energy is called ketosis.

The keto flu can be managed in several ways:

• Staying hydrated: Drinking plenty of water can help reduce symptoms such as headaches and fatigue.
• Replacing electrolytes: Adding electrolytes like salts, potassium, and magnesium to your diet can help stop cramps and nausea.
• Getting plenty of rest: Taking an Epsom salt bath or drinking herbal tea can help soothe and relax your muscles and improve sleep.
• Avoiding strenuous exercise: Light activities like walking, yoga, or leisurely biking may improve symptoms.
• Increasing fat intake: Eating enough fat, the primary fuel source on the ketogenic diet, will help reduce cravings and keep you feeling satisfied.
• Gradually reducing carbs: Some people may need to cut back on carbs slowly over time rather than all at once.

Increased energy

The keto diet is known to cause a significant increase in energy levels. This is because ketones are a superb fuel source for your mitochondria, the powerhouses of your cells. Your brain, in particular, thrives on ketones.

Many people who switch to keto report better mental clarity and more even, sustained energy throughout the day. This is because ketones are an extremely potent fuel source for your brain. They have even been tested in a medical setting to treat brain diseases and conditions such as concussion and memory loss.

Eliminating carbs can also help control and stabilize blood sugar levels, which may further increase focus and improve brain function.

However, it is important to note that in the initial stages of the keto diet, you may experience the "keto flu", which includes symptoms such as brain fog, tiredness, and fatigue. This is because your body is going through a big metabolic change and is forced to adapt to a different system. But these side effects are temporary and usually go away within the first week or two of starting the diet.

To reduce fatigue during the switch to keto, you may want to take electrolyte supplements, especially sodium, potassium, and magnesium.
