Keto for Lower Cholesterol: Is It Possible?
By Tom Seest
At BestKetoNews, we save you time and resources by curating relevant information and news about the keto / ketogenic diet.
The keto diet is a low-carbohydrate diet that may lower cholesterol levels. It is beneficial to include foods that contain monounsaturated fats, including olive oil and nuts. It may also be beneficial to include omega-3 fatty acids, which help lower triglycerides and increase HDL cholesterol. These fats are commonly found in fatty fish, walnuts, and flax seeds.

Low-carb, low-cholesterol diets may lower cholesterol by reducing your daily intake of carbohydrates. A low-carb diet consists of low-carb vegetables and fruits. Many healthy veggies contain less than 10 grams of carbs per serving. These include broccoli, spinach, and kale. Other low-carb veggies include tomatoes, asparagus, and cauliflower. Pumpkin has only six grams per serving.
Cutting out carbohydrates may help you lose weight, but it’s not always a good idea if you’re trying to lower your cholesterol. In one study, people on a low-carb diet lost the same amount of weight as those who followed a high-carb diet. However, the low-carb group’s levels of low-density lipoprotein (LDL), a type of cholesterol that is linked to clogged arteries, increased.
While low-carb diets may reduce LDL cholesterol, they may increase HDL cholesterol. Low-carb diets aren’t for everyone. Eating high-fiber foods and taking niacin supplements are other natural ways to lower cholesterol.
A low-carb diet is a good option if you have a history of heart disease or a genetic mutation that causes high LDL cholesterol. This diet may lower LDL cholesterol and may even reduce triglycerides. In addition to lowering LDL, a low-carb diet can reduce the risk of heart disease by lowering your total cholesterol.
However, the high-fat content of the diet may boost LDL cholesterol. Some patients who are on the diet may experience an initial spike in bad cholesterol, but it will settle down after a few weeks. Researchers from China recently presented their findings at the American College of Cardiology annual meeting in New Orleans.
A low-carb diet containing fruits and vegetables can reduce cholesterol levels in the body. It is also a good idea to eat more unprocessed foods such as nuts and seeds. These foods are rich in fiber and monounsaturated fats. One study suggests that consuming two servings of nuts and seeds per day could lower LDL cholesterol by 7%.
A recent meta-analysis found that carbohydrate restriction reduced LDL cholesterol levels and improved heart health. However, the findings are controversial. The study also found that low carbohydrate diets were associated with increased mortality among patients with myocardial infarction. The study, by Seidelmann and colleagues, included observational studies that included over 20,000 patients.
This study also revealed that carbohydrate-restricted diets increased LDL peak particle size, decreased LDL-P, and reduced the overall LDL-P particle size. However, the changes in the size of LDL particles were not correlated with changes in LDL-P or mean LDL particle size.
In another study, researchers examined data from 548 people on a carbohydrate-restricted diet. They found that the effect of carbohydrate restriction on LDL cholesterol was inversely related to both BMI and TG/HDL-C ratio. This implies that leaner people with lower TG/HDL-C ratios increased LDL-C more during the carbohydrate-restricted diet than their overweight or obese counterparts. These individuals were dubbed Lean Mass Hyper-Responders.
During carbohydrate restriction, peripheral tissues have a greater demand for fat-based fuel. This fuel is derived from non-esterified fatty acids secreted by adipocytes. The liver then repackages the circulating NEFAs into triglycerides. The TGs are then secreted aboard VLDL, where increased lipoprotein-lipase (LPL)-mediated turnover generates increased LDL-C. These changes in LDL cholesterol are related to changes in body weight and energy expenditure.
Carbohydrate restriction is an alternative dietary strategy for dyslipidemia patients. While the dietary guidelines recommend not lowering total cholesterol, carbohydrate restriction may be an effective dietary strategy for those suffering from dyslipidemia. The dietary restriction may reduce HbA1c levels, improve HDL levels, and decrease total cholesterol.
There are several studies that suggest that a ketogenic diet may help lower HDL cholesterol levels. The ketogenic diet is high in fat and low in carbohydrates. It is also known to lower total cholesterol levels. There is a connection between diets high in saturated fat and heart disease, although the research on this connection is limited.
The most important cholesterol marker is LDL particle number. The amount of cholesterol in each LDL particle is measured by blood tests. High LDL particles are associated with higher risks of heart problems and stroke. In addition, a ketogenic diet can improve insulin resistance. This diet also reduces levels of triglycerides.
HDL helps prevent type 2 diabetes by clearing LDL particles from the bloodstream. LDL particles are responsible for transporting energy and nutrients to cells, but they move slowly and tend to get stuck in the bloodstream. Once there, LDL becomes more vulnerable to attack by free radicals, making it easier to sneak into artery walls.
While HDL cholesterol levels decreased after six months on the ketogenic diet, the ratio of LDL cholesterol to apoB did not change significantly. Children with low levels of HDL cholesterol were more likely to be on the diet. Moreover, the levels of apoA-I, the major protein of HDL, did not change significantly between baseline and after six months. Thus, it was found that the ketogenic diet did not significantly decrease the amount of HDL particles in the blood.
This study was approved by the Joint Committee on Clinical Investigation at Johns Hopkins University. All the participants and their parents signed informed consent before participating in the study. This diet was successful in lowering HDL cholesterol and increasing total cholesterol. Moreover, it reduced the levels of triglycerides, glucose, and urea. These changes did not appear statistically significant.
Studies have shown that high-fat and ketogenic diets can lower LDL cholesterol levels. But they also show that the keto diet may increase levels of saturated fat, which increases LDL.
One of the most predictable changes that occur with the ketogenic diet is a dramatic reduction in triglyceride levels. People with metabolic syndrome will usually see their levels drop by half. For those with higher triglyceride levels, the reduction is even greater.
The ketogenic diet forces the body to switch to burning fat for energy rather than carbohydrates. As a result, the amount of insulin secretion and glycogen reserves decrease. This forces the body to adjust to the low availability of glucose. By switching to burning fat, the body produces ketone bodies that replace glucose.
However, this diet may not be right for everyone. It may cause an initial spike in bad cholesterol that will eventually level off after several weeks. One study from China showed that patients who went on a ketogenic diet were at an increased risk of developing atrial fibrillation.
The researchers used a cross-over study design consisting of two four-week diet periods followed by a fifteen-week washout period. The study included men and women with normal weight and a low blood-cholesterol (LDL) level. The participants were randomly assigned to either the ketogenic diet or the control diet. Their weight and physical activity levels were maintained during the study. The study’s primary outcome was LDL cholesterol, although secondary outcomes were also measured.
The diet also decreased total cholesterol and LDL cholesterol significantly. In addition, HDL cholesterol levels increased. Although it is unclear whether the ketogenic diet causes hyperlipidemia, it is worth considering. However, further studies are needed to determine whether the ketogenic diet has any cardiovascular risks.
Results of the study show that the KD does reduce the level of triglycerides. Its effectiveness is similar among the four types of KD. The mechanism of action may be different among them. It is, therefore, important to seek out a diet that will meet your specific health needs.
Researchers have conducted various studies to study the effects of the ketogenic diet on triglycerides in obese subjects. However, the long-term effects are not yet known. In short, the ketogenic diet can reduce triglyceride levels in patients with high cholesterol levels.
