Many wonder if a diet high in fat is good for the heart. The keto diet has 75% fats, 20% protein, and 5% carbs1. It’s natural to wonder how it affects our heart.
The keto diet can raise HDL “good” cholesterol levels1 and lower blood sugar2. But how does this affect our heart health?
The link between the keto diet and heart health is complex. Some studies show it may lower triglycerides2 and control blood sugar1. But others worry about its effects on heart disease and cholesterol.
With up to 70% of the heart’s fuel coming from fat2, the keto diet’s impact is significant.
Key Takeaways
- The keto diet consists of 75% fats, 20% protein, and 5% carbohydrates1.
- The keto diet may lower blood sugar levels2 and improve HDL “good” cholesterol levels1.
- Up to 70% of fuel for the heart is derived from fat2.
- The keto diet can lower triglycerides2 and improve blood sugar control1.
- Clinical guidelines from the American Heart Association recommend a balanced diet for heart patients2.
- Patients on the keto diet may experience side effects such as nausea, vomiting, and fatigue2.
Understanding the Keto Diet and Its Principles
The keto diet is all about eating lots of fat and very few carbs. It helps your body use fat for energy instead of carbs3. You eat 70% fat, 20% protein, and just 10% carbs3.
By eating only 20 to 50 grams of carbs a day, your body starts using ketones for energy3. Ketones are made from fat in your liver.
Eating less carbs can make you lose weight and control blood sugar better4. It also makes your body more sensitive to insulin, which is good3. Plus, it can lower heart disease risk by improving body fat and cholesterol levels3. For more info, check out keto diet ideas.
Healthy fats like nuts, seeds, and avocados are key in a keto diet4. Also, eat low-carb veggies like leafy greens4. Drinking plenty of water and watching how your body reacts is important too3. With the right plan, the keto diet can help you lose weight and feel better5.
The Relationship Between Diet and Heart Health
A healthy diet is key for good heart health. The keto diet can have both good and bad effects on the heart. It’s important to know how different diets affect cardiovascular disease risk6.
A study showed that a “keto-like” diet might double the risk of heart problems. This includes chest pain, blocked arteries, heart attacks, and strokes6.
Eating a diet high in fat and low in carbs can raise LDL cholesterol. This increases the risk of heart disease7. The study looked at data from over 500,000 people in the UK Biobank8.
About 1 in 5 Americans follow a low-carb or keto diet6. It’s important to think about the keto diet’s effects on the heart and cardiovascular disease risk.
| Dietary Pattern | Cardiovascular Disease Risk |
|---|---|
| Low-carbohydrate, high-fat (LCHF) diet | Increased risk of cardiovascular events |
| Standard diet | Lower risk of cardiovascular events |
The keto diet may double the risk of heart problems. This includes chest pain, blocked arteries, heart attacks, and strokes8. It’s important to consider the keto diet’s benefits and risks for the heart and cardiovascular disease risk7.
The Science Behind Keto and Heart Health
The keto diet can have both good and bad effects on heart health. It changes how we get our cholesterol and triglycerides. These are key factors in heart disease9.
On a keto diet, we eat a lot more fat. This is 75% of our calories, compared to 20-35% in regular diets9. This can raise the “bad” cholesterol, LDL10.
But, the keto diet might also increase “good” cholesterol, HDL10. It’s also important to know how it affects triglycerides. High triglycerides can harm the heart8.
Research shows the keto diet can improve weight and metabolic issues, including triglycerides10.
Not everyone should try the keto diet, though. It’s not good for those with high cholesterol or heart disease8. The American Heart Association says there’s not enough proof it’s good for the heart10.
So, talk to a doctor before starting a keto diet. This is very important if you’re worried about your cholesterol or triglycerides108.
In short, the keto diet’s impact on heart health is complex. It might help with weight and metabolic issues. But, we need to think about the risks, like cholesterol and triglyceride levels9108.
Nutrients to Focus on in a Keto Diet
A good keto diet has lots of healthy fats, important vitamins and minerals, and enough fiber. This helps keep your heart healthy11. It’s key to know why these nutrients matter and how to add them to your meals. The keto diet might lack fiber, which helps control blood sugar and keeps you full.
Some important nutrients to pay attention to are:
- Healthy fats: Good for your heart and found in avocados, nuts, and olive oil.
- Essential vitamins and minerals: Needed for your body’s functions and in foods like leafy greens, meats, and fish.
- Fiber: Good for your digestion and in veggies, fruits, and whole grains, but less on a keto diet12.
By focusing on these nutrients and having a balanced keto diet, you can keep your health up. This might even lower heart disease risk11. Always talk to a doctor before starting a new diet to make sure it’s right for you.
Potential Benefits of Keto for Heart Health
The keto diet may help your heart in many ways. It can lead to weight loss, lower inflammation, and keep blood sugar stable13. Losing weight can lower your risk of heart disease and make you healthier13. It also fights inflammation, a big risk for heart disease14. Plus, it helps keep blood sugar levels steady, which is good for your health and heart15.
Some key benefits of the keto diet for heart health include:
- Weight loss, which can help reduce the risk of heart disease13
- Reducing inflammation, which can help reduce the risk of heart disease14
- Stabilizing blood sugar levels, which is important for overall health and can help reduce the risk of heart disease15
The keto diet could be a great way to boost heart health. It helps with weight loss, lowers inflammation, and keeps blood sugar stable13. But, always talk to a doctor before starting any new diet, even if you’re healthy14. With the right help, the keto diet can be safe and effective for better health and lower heart disease risk15.
Risks of Keto for Heart Health
The keto diet may pose risks for heart health. These include concerns over saturated fats and cholesterol levels. It’s also important to watch for nutrient deficiencies16. A diet high in saturated fats could increase heart disease risk. Knowing these risks is key when on a keto diet.
Some risks include a higher chance of neural tube defects in babies for pregnant women. Even with folic acid, there’s a risk16. Higher-protein keto diets might also speed up kidney failure in those with kidney disease16. It’s important to be cautious and take steps to avoid these risks. For more info, visit keto diet ideas and talk to a doctor.
It’s also key to watch cholesterol levels on a keto diet. The “good” cholesterol (HDL) might go up with more fat17. But, keto diets can also raise LDL cholesterol (the “bad” kind) for many16. Keeping cholesterol levels balanced is vital.
In summary, the keto diet might have heart health benefits but also risks. It’s important to know these risks and take steps to avoid them. By understanding the risks and taking precautions, you can make smart choices about your diet and health.

A heart-healthy keto diet should have many foods. These foods give important nutrients and keep carbs low. Healthy oils like olive oil are full of oleic acid. This acid helps lower heart disease risks19.
Nuts and seeds, like almonds and chia seeds, are also good. They are full of healthy fats and fit well in a keto diet20.
Leafy greens, like spinach and kale, are packed with vitamins and minerals. They can be part of a keto meal plan19. Avocados are another great fat source. They can be used in salads or smoothies.
A keto diet is full of healthy fats. These fats are key for heart health. It also includes many veggies and fruits that are full of nutrients.

Adding these foods to a keto meal plan helps support health and heart health. This is while following a keto diet21.
Foods to Avoid on a Heart-Healthy Keto
Following a keto diet means you need to stay away from certain foods. These foods can harm your heart health. You should avoid processed meats, sugary snacks and drinks, and foods high in sodium22. These can raise your risk of heart disease and other health issues.
Some foods to limit or avoid include:
- Processed meats like hot dogs and sausages, which are high in sodium and preservatives23
- Sugary snacks like candy and baked goods, which can cause a spike in blood sugar and insulin levels22
- High-sodium foods like soy sauce and processed soups, which can increase blood pressure and cardiovascular risk23
Also, watch your carb intake on a keto diet. It’s usually 20 to 50 grams per day22. Foods like white bread, pasta, and sugary drinks can quickly raise your carb levels. Instead, eat whole, nutrient-rich foods like veggies, nuts, and healthy oils. These support your health and heart health.
