Find out “Is Keto Bad for Your Heart Or Not?” The ketogenic diet, commonly known as the keto diet, has gained significant popularity in recent years for its potential weight loss benefits and improved metabolic function.
However, concerns have been raised about the impact of the keto diet on heart health. In this article, we will explore whether the keto diet is bad for your heart and provide strategies to minimize cardiovascular risks while following this eating approach.
How Does the Keto Diet Work?
Starting the keto diet requires followers to restrict their intake of carbohydrates, which the body usually uses for fuel. Instead, it begins burning its own stored fat, converting it into ketones to use as energy.
Known as ketosis, this process helps people to lose weight, manage their blood sugar, and stabilize their energy levels.
As a rough guide, it’s recommended to get 70–80% of your daily calories from fat, 10–20% from protein, and 5–10% from carbs to remain in ketosis.
Benefits of the keto diet
Choosing a high-fat, low-carb diet has several possible advantages for your health. Some of the potential health benefits of keto are that it:
- Helps with weight loss
- May reduce appetite
- Lowers blood sugar levels for a reduced risk of diabetes
- Lowers triglycerides, a type of fat in the blood
- Higher levels of high-density lipoproteins (HDLs), or “good” cholesterol
- Increases energy levels
- Protects brain function
- Reduces the risk of cancer
Risks of the keto diet
Along with potentially damaging your heart health, there are some other risks to consider if you’re thinking about trying the keto diet. For example, it isn’t safe for those with health conditions that involve the thyroid, liver, pancreas, or gallbladder.
Below are some of the other things to think about before switching to this low-carb diet:
- Seen as restrictive by some
- Can be difficult to maintain for long periods
- Its long-term impacts remain unclear
- Can lead to nutrient deficiencies
- Has been linked to hair loss
- May cause an irregular menstrual cycle
- Could result in digestive issues
Impact of the Keto Diet on Heart Health
The Role of Ketosis
Ketosis itself is not inherently bad for the heart. In fact, some studies suggest that ketones may have potential benefits for heart health, such as reducing inflammation and oxidative stress. However, it’s important to consider the overall composition of the diet and its impact on cardiovascular risk factors.
Effect on Cholesterol Levels
One concern often associated with the keto diet is its potential to raise cholesterol levels, specifically LDL (low-density lipoprotein) cholesterol. LDL cholesterol is often referred to as “bad” cholesterol because high levels can increase the risk of heart disease. While the keto diet may initially lead to an increase in LDL cholesterol, it typically also raises HDL (high-density lipoprotein) cholesterol, which is considered “good” cholesterol. It’s crucial to maintain a balance and focus on the quality of fats consumed.
Influence on Blood Pressure
The keto diet has been shown to have mixed effects on blood pressure. Some individuals may experience a reduction in blood pressure, which can be beneficial for heart health. However, others may see an increase or no significant change. It is important for individuals with existing high blood pressure or other cardiovascular conditions to monitor their blood pressure closely and consult with a healthcare professional.
Strategies to Minimize Cardiovascular Risks on Keto
While the keto diet may pose some potential risks to heart health, there are strategies you can follow to minimize these risks and promote cardiovascular well-being:
1. Choose Healthy Sources of Fats
Opt for high-quality, heart-healthy fats such as avocados, nuts, seeds, olive oil, and fatty fish. These fats are rich in monounsaturated and polyunsaturated fats, which have been shown to have positive effects on heart health.
2. Incorporate Nutrient-Rich Foods
Focus on incorporating nutrient-dense foods into your keto diet, including vegetables, fruits in moderation, lean proteins, and whole grains (if tolerated). These foods provide essential vitamins, minerals and fiber, which are important for overall heart health.
3. Monitor Electrolyte Balance
When following the keto diet, there is an increased risk of electrolyte imbalances, particularly due to the diuretic effect of ketosis. It is essential to ensure an adequate intake of electrolytes, such as sodium, potassium, and magnesium, to maintain proper heart function. Consider incorporating electrolyte-rich foods or using electrolyte supplements under the guidance of a healthcare professional.
4. Stay Hydrated
Proper hydration is crucial for cardiovascular health. Drinking an adequate amount of water throughout the day helps maintain blood volume and supports optimal heart function. Additionally, staying hydrated can help prevent potential side effects of the keto diet, such as constipation and kidney stones.
5. Engage in Regular Physical Activity
Physical activity plays a significant role in maintaining heart health. Regular exercise helps improve cardiovascular fitness, lowers blood pressure, reduces inflammation, and promotes overall well-being. Incorporate a combination of aerobic exercises, strength training, and flexibility exercises into your routine.
6. Consult a Healthcare Professional
Before embarking on any diet or lifestyle change, it is important to consult with a healthcare professional, especially if you have pre-existing cardiovascular conditions or other health concerns. They can provide personalized guidance, monitor your progress, and ensure that the keto diet is suitable for your individual needs.
A Word From a Nutritionist
The keto diet has several positive short-term effects on your health, including helping with weight loss, controlling your blood sugar levels, and even boosting good HDL cholesterol levels. However, following a keto diet also comes with other risk factors for your heart health.
If you’re hoping to lose weight or boost your overall well-being, but are worried about any long-term heart problems you may develop, then try to eat foods that are low in saturated fats yet high in healthy omega-3 fatty acids.
Alternatively, you could try a higher-carb option like a vegan or the Mediterranean diet. These diets don’t rely on fats for most of your nutrition, so you’re less likely to consume large amounts of unhealthy saturated fats.
As with any new diet, consult your doctor before switching to keto. They can advise you on whether this diet is suitable, as it should be avoided by those who have conditions involving the pancreas, liver, thyroid, or gallbladder.
Doctors will also monitor your cholesterol levels and other risk factors to ensure that you don’t develop serious heart problems.
Conclusion
The keto diet, when followed properly and with consideration for cardiovascular health, may not be inherently bad for your heart. It is crucial to focus on the quality of fats consumed, incorporate nutrient-rich foods, monitor electrolyte balance, stay hydrated, engage in regular physical activity, and seek guidance from a healthcare professional. By following these strategies, you can minimize potential cardiovascular risks and support overall heart health while on the keto diet.
