Ketosis And High Blood Pressure: Is There A Link?

The ketogenic diet is a high-fat, low-carbohydrate diet that can help people lose weight and improve their health. When you follow this type of diet, your body enters a state of ketosis, which means that it starts to burn fat for energy instead of carbohydrates. This process can lead to weight loss and improved health.

For people with hypertension, the keto diet can be beneficial as it can help to lower blood pressure. This is because when you are in a state of ketosis, your body releases less insulin, which can help to reduce inflammation and improve blood pressure. In addition, the keto diet can also help to reduce the risk of heart disease and other chronic conditions.

However, if your blood pressure increases after starting the diet, a couple of things may be happening. Firstly, adapting to keto and/or dieting is increasing your stress levels, which leads to higher blood pressure. Secondly, you may have certain genes that cause higher sodium intake to increase blood pressure.

It is important to note that keto isn't right for everyone. Those who are pregnant or may become pregnant should not eat a keto diet. If you already have low blood pressure, ketosis could lower your blood pressure dangerously. Additionally, there is medical evidence that prolonged ketosis (longer than a few months) can have negative health effects, such as heart disease.

Ketosis can lower blood pressure

Ketosis is a metabolic state in which the body uses ketone bodies (a type of fuel produced by the liver from fat) instead of sugar or glucose from carbohydrates. To achieve ketosis, an extremely strict and difficult-to-maintain ketogenic (keto) diet is required. This typically involves a diet of 75% fat, 5% carbohydrates, and 15% protein.

Weight Loss and Blood Pressure

Ketosis can be an effective method of weight loss, especially for obese people and those with diabetes. When an obese person loses weight, other metabolic markers such as inflammation, cholesterol levels, and blood pressure tend to improve too.

Studies on Keto and Blood Pressure

Several studies suggest that keto may help treat or prevent hypertension. For example, in a study comparing keto with three other diets, overweight premenopausal women had greater reductions in systolic and diastolic blood pressure on a keto diet than on the Zone, LEARN, or Ornish diets.

Another study compared a keto diet with a low-fat diet plus Orlistat (a drug for weight loss and high blood pressure). Results showed that blood pressure fell in the keto group but rose in the low-fat group.

Risks and Considerations

While keto may help lower blood pressure for some people, it is not a guarantee for everyone. A "dirty keto" diet, for example, may be short on potassium from vegetables, leading to high sodium levels from salty processed meat. Too much sodium without enough potassium will raise blood pressure.

Additionally, too little sodium can also raise blood pressure as low-carb diets increase urinary sodium loss. When there is not enough sodium in the body, it releases aldosterone, a hormone that raises blood pressure.

It is always recommended to consult a healthcare professional before starting any new diet, especially one as strict as keto, to ensure it is safe and appropriate for your individual needs.

Ketosis can help fight hypertension

Hypertension, or high blood pressure, is a common condition affecting around a third of all Americans. It is a well-documented risk factor for heart attack and stroke and can also increase the risk of dementia.

The ketogenic diet is a high-fat, low-carbohydrate diet that can help people lose weight and improve their health. When you follow this type of diet, your body enters a state of ketosis, which means that it starts to burn fat for energy instead of carbohydrates. This process can lead to weight loss and improved health.

Ketosis can help to lower blood pressure in several ways:

• Weight loss: Ketosis can help you lose weight more quickly than other diets, and weight loss is often associated with improved blood pressure.
• Appetite suppression: The ketogenic diet is associated with reduced appetite, which can lead to weight loss and improved blood pressure.
• Increased energy expenditure: Ketosis can increase your energy levels, which can contribute to weight loss and improved blood pressure.
• Lowered insulin levels: Ketosis can lead to lower insulin levels, which causes more fat to be burned and can help improve blood pressure.
• Reduced inflammation: Lower insulin levels can also help to reduce inflammation, which is a risk factor for hypertension.

Several studies have shown that the ketogenic diet may be effective in lowering blood pressure:

• One study compared the ketogenic diet to three other diets: the Zone diet (30% carbs), the LEARN diet (60% carbs), and the Ornish Diet (10% fat calories). The ketogenic diet group saw the greatest improvement in systolic blood pressure, with a reduction that was twice as much as that of the other diets.
• Another study compared the ketogenic diet to a low-fat diet plus Orlistat, a drug used for weight loss and high blood pressure. The ketogenic diet group experienced a reduction in blood pressure, while the low-fat and Orlistat group saw an increase.
• A small study of people with metabolic syndrome who followed a ketogenic diet for 12 weeks experienced significant reductions in blood pressure, along with weight loss and other health improvements.
• In a very-low-carb diet study, 11% of participants had to discontinue blood pressure medications due to reductions in blood pressure.

Precautions and considerations

While the ketogenic diet can be an effective tool for lowering blood pressure, there are some considerations to keep in mind:

• Sodium and potassium intake: Too much sodium or too little potassium can raise blood pressure. If you are following a ketogenic diet, ensure you are getting enough potassium from low-carb vegetables, avocados, and supplements, and limit your salt intake.
• Stress levels: If adapting to the ketogenic diet is increasing your stress levels, it could lead to higher blood pressure.
• Genetic factors: Certain genetic factors, such as genes that cause higher sodium intake to increase blood pressure, may affect how the ketogenic diet impacts your blood pressure.
• Individual differences: The ketogenic diet may not be suitable for everyone. It is important to consult your doctor before starting any new diet, especially if you have high blood pressure or other health conditions.

Ketosis can cause low blood pressure

Ketosis is a metabolic state in which the body uses ketone bodies—produced from the breakdown of fats in the liver—as its main source of energy, instead of glucose. Low-carbohydrate, ketogenic diets are a popular way to achieve ketosis, with the aim of weight loss and other potential health benefits.

While ketosis is often associated with increased blood pressure, there is evidence to suggest that it can also cause low blood pressure in certain individuals. This effect is particularly relevant for people who are taking blood pressure medication and have high blood pressure before starting a low-carb diet.

Ketogenic diets can lead to a rapid reduction in blood pressure, especially in those with high blood pressure. This effect is likely due to a combination of weight loss, reduced insulin secretion, and improved insulin sensitivity. Additionally, during the transition to ketosis, people stop retaining water and salt, leading to increased urination and loss of sodium, which can further lower blood pressure.

Who Is at Risk of Low Blood Pressure Due to Ketosis?

Those who are taking blood pressure medication and begin a low-carb diet are at risk of experiencing low blood pressure. This is because the diet may work "too well," leading to a sudden drop in blood pressure that makes the previous dosage of medication too high.

People with normal or slightly low blood pressure before starting a ketogenic diet may also experience a further drop in blood pressure, leading to symptoms such as light-headedness, dizziness, or nausea.

Managing Low Blood Pressure During Ketosis

If you experience symptoms of low blood pressure, it is important to check your blood pressure and consult your doctor to discuss adjusting your medication. Additionally, increasing your intake of electrolytes, such as sodium and potassium, can help raise blood pressure. This can be done by consuming salted bone broth, adding salt to water, or taking supplements.

It is worth noting that the risk of low blood pressure due to ketosis is generally higher for those on blood pressure medication, and the effect usually occurs within days to a few weeks of starting the diet.

Ketosis and weight loss

Ketosis is a metabolic state that occurs when your body burns fat for energy instead of glucose. The keto diet is high in fat, moderate in protein, and low in carbohydrates. The standard keto diet consists of 70% to 80% fats, 10% to 20% proteins, and 5% to 10% carbohydrates.

Ketosis has been shown to be an effective weight-loss strategy. It can help you feel less hungry, which may lead to eating less food. It can help you lose belly fat while maintaining lean mass. Research has shown that ketosis may have several health benefits, including weight loss. The process can help you feel less hungry, which may lead to eating less food. It can help you lose belly fat (visceral fat) while maintaining lean mass.

The keto diet has been shown to produce beneficial metabolic changes in the short term. Along with weight loss, health parameters associated with carrying excess weight have improved, such as insulin resistance, high blood pressure, and elevated cholesterol and triglycerides.

The premise of the ketogenic diet for weight loss is that if you deprive the body of glucose—the main source of energy for all cells in the body, which is obtained by eating carbohydrate-rich foods—an alternative fuel called ketones is produced from stored fat. The brain demands the most glucose in a steady supply because it cannot store glucose. During fasting, or when very few carbohydrates are eaten, the body first pulls stored glucose from the liver and temporarily breaks down muscle to release glucose. If this continues for 3-4 days and stored glucose is fully depleted, blood levels of a hormone called insulin decrease, and the body begins to use fat as its primary fuel. The liver produces ketone bodies from fat, which can be used in the absence of glucose.

When ketone bodies accumulate in the blood, this is called ketosis. Healthy individuals naturally experience mild ketosis during periods of fasting (e.g., sleeping overnight) and very strenuous exercise.

Who should avoid it?

The keto diet can be difficult to follow and may produce side effects including "keto" breath, constipation, and "keto flu," which includes symptoms such as upset stomach, headache, and fatigue.

Some negative side effects of a long-term ketogenic diet have been suggested, including an increased risk of kidney stones and osteoporosis, and increased blood levels of uric acid (a risk factor for gout). Possible nutrient deficiencies may arise if a variety of recommended foods on the ketogenic diet are not included.

• Strong emphasis on fats at each meal and snack to meet the high-fat requirement. Cocoa butter, lard, poultry fat, and most plant fats (olive, palm, coconut oil) are allowed, as well as foods high in fat, such as avocado, coconut meat, certain nuts (macadamia, walnuts, almonds, pecans), and seeds (sunflower, pumpkin, sesame, hemp, flax).
• Some dairy foods may be allowed. Butter and hard cheeses may be consumed because of their lower lactose content.
• Protein stays moderate. Grass-fed beef (not grain-fed), free-range poultry, pork, bacon, wild-caught fish, organ meats, eggs, tofu, certain nuts and seeds are recommended.
• Most non-starchy vegetables are included: Leafy greens (kale, Swiss chard, collards, spinach, bok choy, lettuces), cauliflower, broccoli, Brussels sprouts, asparagus, bell peppers, onions, garlic, mushrooms, cucumber, celery, summer squashes.
• Certain fruits in small portions like berries. Despite containing carbohydrates, they are lower in “net carbs” than other fruits.
• Other: Dark chocolate (90% or higher cocoa solids), cocoa powder, unsweetened coffee and tea, unsweetened vinegars and mustards, herbs, and spices.

Ketosis and high blood pressure medication

Ketosis is a metabolic state in which the body uses fat as its primary energy source instead of carbohydrates. It can be induced by following a low-carbohydrate, high-fat ketogenic diet. This dietary approach has gained popularity in recent years due to its potential benefits for weight loss and certain health conditions. One question that often arises is whether ketosis can cause or affect high blood pressure, which is a common health concern.

Ketosis and Blood Pressure

Research suggests that ketosis can have a positive impact on blood pressure. When an obese or overweight individual loses weight through ketosis, their blood pressure tends to improve. This is because obesity is a significant risk factor for hypertension (high blood pressure). By reducing body fat, ketosis can help lower blood pressure and improve overall cardiovascular health.

Several studies have found that a ketogenic diet may be effective in treating or preventing hypertension. For example, one study compared the ketogenic diet to three other popular diets: the Zone diet (30% carbs), the LEARN diet (60% carbs), and the Ornish Diet (10% fat calories). The results showed that participants on the ketogenic diet experienced greater reductions in systolic and diastolic blood pressure compared to those on the other diets.

Another study compared the ketogenic diet to a low-fat diet plus Orlistat, a drug used for weight loss and high blood pressure. Interestingly, blood pressure decreased in the ketogenic diet group but increased in the low-fat diet plus Orlistat group. These findings suggest that ketosis may be a viable approach for managing blood pressure in individuals with obesity or overweight.

However, it is important to note that ketosis may not improve all cases of high blood pressure. The impact of ketosis on blood pressure can vary depending on individual factors, such as genetic predisposition, lifestyle, and dietary choices.

Ketosis and Blood Pressure Medication

For individuals taking blood pressure medication, adopting a ketogenic diet may lead to some unique considerations. Since ketosis can lower blood pressure, there is a risk of the diet causing blood pressure to drop too low if not properly managed. This is especially relevant for individuals taking blood pressure-lowering medications.

When starting a ketogenic diet, it is crucial to monitor blood pressure closely, especially during the initial weeks. If symptoms of low blood pressure occur, such as feeling weak, tired, or dizzy, it is important to check your blood pressure and consult with a doctor. Adjustments to medication dosage or diet may be necessary to maintain optimal blood pressure levels.

Additionally, sodium and potassium intake play a crucial role in blood pressure regulation during ketosis. A ketogenic diet that is high in processed meats and low in vegetables can lead to excessive sodium intake and insufficient potassium, which can raise blood pressure. On the other hand, extremely low sodium intake can also increase blood pressure. Therefore, maintaining a balanced intake of these electrolytes is essential for managing blood pressure while in ketosis.

In summary, ketosis can be a powerful tool for managing blood pressure, especially in individuals with obesity or overweight. However, for those taking blood pressure medication, it is important to work closely with a healthcare professional to adjust medication dosages and monitor blood pressure levels during the transition to ketosis.
