The carnivore diet, which consists mostly of animal-based products and few or no plant foods, has become increasingly popular. While some people report benefits such as improved overall health, reduced BMI, and high satisfaction with the diet, there are concerns about its impact on cholesterol levels and cardiovascular health. The diet is high in saturated fats, which can increase low-density lipoprotein (LDL), or bad cholesterol, leading to a buildup in blood vessels and an increased risk of heart disease. However, the overall impact on cholesterol may depend on various factors, and some studies suggest that the diet may contribute to a healthier cholesterol profile over time.
| Characteristics | Values |
|---|---|
| LDL cholesterol increase | Many sources claim that the carnivore diet increases LDL cholesterol, which is associated with an increased risk of cardiovascular issues like heart disease, heart attacks, and strokes. |
| HDL cholesterol increase | Some sources state that the carnivore diet may increase HDL ("good") cholesterol, which could offset the potential risks of higher LDL levels. |
| Weight loss | The carnivore diet is high in protein and may promote weight loss, which is often associated with lower cholesterol levels. |
| Individual variation | Individual responses to the diet vary, and some people may experience a decrease in LDL cholesterol. |
| Lack of research | There is limited research on the carnivore diet's effects on cholesterol, and more studies are needed to draw definitive conclusions. |
| Cardiovascular risks | The carnivore diet is high in saturated fats and may increase cardiovascular risks, but some studies suggest it may have benefits like improved heart health markers and reduced BMI. |
| Gastrointestinal issues | Some people may experience gastrointestinal side effects like diarrhea and constipation. |
| Yellow lumps on skin | In rare cases, extremely high cholesterol levels caused by the carnivore diet may lead to the development of yellow lumps on the palms of the hands or eyelids, known as xanthelasmas. |

The carnivore diet increases LDL cholesterol
The carnivore diet, which consists mostly of animal-based products and excludes plant foods, has been associated with an increase in LDL cholesterol. LDL cholesterol, otherwise known as "bad" cholesterol, can contribute to heart disease and other negative health effects when it builds up in the blood vessels. This build-up can restrict blood flow to the heart and other organs, increasing the risk of a heart attack or stroke.
A case study of a man in his 40s who ate a carnivore diet for eight months reported cholesterol levels of 1,000, which is much higher than the healthy level of under 200. He developed yellow lumps on his hands, which were deposits of excess cholesterol that had built up under his skin. His diet consisted of very high amounts of fat and protein, including 6 to 9 pounds of cheese a day, butter, and fatty meats.
Research has shown that the carnivore diet can lead to higher LDL cholesterol levels, which is concerning for heart health. A 2021 study of 2,029 people following a carnivore diet for 14 months found higher LDL cholesterol levels in participants, despite their reports of minimal negative effects. While some people may experience an increase in cholesterol levels on the carnivore diet, they may also see improvements in other health markers, such as reduced inflammation, weight loss, and better blood sugar control, which could offset potential risks.
However, it is important to note that individual responses to diets vary, and there is a lack of research specifically on the carnivore diet and its effects on health. Some studies suggest that the carnivore diet may contribute to a healthier cholesterol profile over time. Additionally, the high protein content of the carnivore diet can lead to weight loss, which is often associated with decreased cholesterol levels.
The American College of Cardiology (ACC) does not recommend the carnivore diet, instead emphasizing balanced dietary patterns for cardiovascular health. To reduce cholesterol levels, the Centers for Disease Control and Prevention (CDC) recommends limiting foods with saturated fats, such as cheese, fatty meats, and full-fat dairy.

This can lead to a higher risk of heart disease
The carnivore diet, which mostly comprises animal-based products and excludes most or all plant foods, has gained popularity in recent years. However, it may increase levels of low-density lipoprotein (LDL), or “bad” cholesterol. This is because foods deriving from animals, including red meat, butter, and cheese, are high in saturated fats, which have been shown to increase LDL cholesterol.
LDL cholesterol can build up in the blood vessels, narrowing them and restricting blood flow to the heart and other organs. This raises a person’s risk of a heart attack or stroke, which can lead to a higher risk of heart disease. While some studies suggest the carnivore diet has benefits, there is a lack of research on how it affects health.
A 2021 study conducted a social media survey and gathered self-reported data from 2,029 people following a carnivore diet for 14 months. Despite researchers' concerns about nutrient deficiencies and cardiovascular risks, 95% of participants reported experiencing health improvements and high satisfaction with the diet. While the researchers observed higher LDL cholesterol levels in the participants, other heart health markers were positive. Their high-density lipoprotein (HDL), or “good” cholesterol levels, were optimal.
However, it's important to note that cholesterol isn't inherently bad, and the body needs cholesterol for essential functions. The key is the balance between LDL and HDL cholesterol. While some people may experience an increase in cholesterol levels on the carnivore diet, they may also see improvements in other markers of health such as reduced inflammation, weight loss, and better blood sugar control, which could offset potential risks.
Additionally, individual responses to diets can vary greatly, and more research is needed to understand the impact of the carnivore diet on cholesterol levels fully. Regular physical activity is also a powerful tool for maintaining heart health and managing cholesterol levels, as it helps increase HDL while lowering LDL.

However, it also increases HDL cholesterol
The carnivore diet, which mostly comprises animal-based products and excludes most or all plant foods, has gained popularity in recent years. However, it has been linked to an increase in LDL cholesterol, which is known as "bad" cholesterol. This is because animal-derived foods, such as red meat, butter, and cheese, are high in saturated fats, which have been shown to increase LDL cholesterol levels. High LDL cholesterol can build up in the blood vessels, narrowing them and restricting blood flow to the heart and other organs, thereby increasing the risk of a heart attack or stroke.
However, it is important to note that cholesterol is not inherently bad, and the body needs cholesterol for essential functions. The key is to maintain a healthy balance between LDL and HDL cholesterol. Interestingly, some studies and anecdotal evidence suggest that the carnivore diet may contribute to a healthier cholesterol profile over time. This may be due to the elimination of carbohydrates, particularly refined sugars and grains, which can trigger inflammation and insulin resistance, major drivers of high cholesterol levels.
In support of this, a 2021 survey of 2,029 people following a carnivore diet for 14 months reported minimal negative effects. While researchers observed higher LDL cholesterol levels in the participants, their HDL cholesterol levels, also known as "good" cholesterol, were optimal. Additionally, participants reported a reduction in body mass index (BMI) and improvements in other health markers, such as reduced inflammation, weight loss, and better blood sugar control. These positive effects may help offset the potential risks associated with elevated LDL cholesterol levels.
Furthermore, the carnivore diet's high protein content can lead to weight loss, which is often associated with a decrease in overall cholesterol levels. Regular physical activity can also help maintain heart health and manage cholesterol levels by increasing HDL cholesterol while lowering LDL cholesterol. Despite these potential benefits, individual responses to the diet vary, and more research is needed to understand the carnivore diet's effects on cholesterol fully.

There is a lack of research on the diet
The carnivore diet has gained popularity in recent years. It mostly comprises animal-based products and excludes most or all plant foods. While some people have reported benefits to the diet, including optimal levels of HDL ("good" cholesterol), a reduced BMI, improved overall health, and high satisfaction with the diet, there is a lack of research on the diet and how it affects health.
Some studies suggest that the carnivore diet has benefits. A 2021 study conducted a social media survey and gathered self-reported data from 2,029 people following a carnivore diet for 14 months. Of the participants, 95% reported experiencing health improvements and high satisfaction with the diet. While the researchers observed higher LDL cholesterol levels in the participants, other heart health markers were positive. Their high-density lipoprotein (HDL), or "good" cholesterol levels, were optimal. Participants also reported a reduction in body mass index (BMI), while those with diabetes reported reductions in glycated hemoglobin (HbA1c) and diabetes medication use.
However, the data came from self-reported perceptions of people's health, and the researchers themselves had concerns about nutrient deficiencies and cardiovascular risks. The ACC does not recommend the carnivore diet, emphasizing instead balanced dietary patterns for cardiovascular health and longevity.
The carnivore diet may increase levels of LDL cholesterol, known as "bad" cholesterol. This is largely due to the high intake of saturated fats found in meat, which can stimulate the liver to produce more cholesterol. Foods deriving from animals, including red meat, butter, and cheese, are high in saturated fats. Saturated fats have been shown to increase LDL cholesterol, which can build up in the blood vessels, narrowing them. This narrowing can restrict blood flow to the heart and other organs, raising a person's risk of a heart attack or stroke.
However, it's important to remember that cholesterol isn't inherently bad, and the body needs cholesterol for essential functions. The key is the balance between LDL and HDL cholesterol. While some people may experience an increase in cholesterol levels, they may also see improvements in other markers of health such as reduced inflammation, weight loss, and better blood sugar control, which could offset potential risks. Some studies and anecdotal evidence suggest that over time, the carnivore diet may contribute to a healthier cholesterol profile.

Individual responses vary
Individual responses to the carnivore diet vary. While some people may experience an increase in cholesterol levels, they may also see improvements in other markers of health, such as reduced inflammation, weight loss, and better blood sugar control, which could offset potential risks.
For example, a case study reported a man in his 40s who ate "very extreme amounts of fat and protein" as part of the carnivore diet and developed yellow lumps on the palms of his hands—deposits of excess cholesterol under his skin. His total blood cholesterol was over 1,000, one of the highest results the doctor had ever seen.
On the other hand, some people have reported benefits from the carnivore diet, including optimal levels of HDL ("good" cholesterol), a reduced BMI, improved overall health, and high satisfaction with the diet.
It's worth noting that the current body of research on the carnivore diet and cholesterol is limited, and more studies are needed to draw definitive conclusions. The impact of the carnivore diet on cholesterol levels may depend on various factors, including the specific types and cuts of meat consumed, the inclusion of fatty fish, and individual variations in genetics and lifestyle factors.
Additionally, the carnivore diet's elimination of carbohydrates, particularly refined sugars and grains, may play a role in reducing cholesterol levels for some individuals. These foods can trigger inflammation and insulin resistance, which are major drivers of high cholesterol levels. By removing them from the diet, some people may see a decrease in LDL cholesterol and an increase in HDL cholesterol, leading to a better overall balance.
Furthermore, the high protein content of the carnivore diet can promote weight loss, which is often associated with a decrease in cholesterol levels. However, it's important to remember that weight loss is not guaranteed with the carnivore diet, and individual responses can vary greatly.
While the carnivore diet may work for some people, it's always recommended to consult a medical professional before starting any new diet, especially one that may significantly impact cholesterol levels and cardiovascular health.
