Keto Diet: A Solution To Fatty Liver?

Fatty liver disease is a condition where fat accumulates in the liver, causing inflammation and dysfunction. It can be caused by excessive alcohol use or other factors unrelated to alcohol. The two types of fatty liver disease are alcoholic fatty liver disease and nonalcoholic fatty liver disease (NAFLD).

The keto diet is a very low-carbohydrate diet that can be beneficial for people with NAFLD because it can decrease insulin levels, help reverse the disease process, and suppress appetite, promote weight loss, and improve heart health markers.

Research has shown that the keto diet can reduce liver fat and protect the liver from further injury. It can also lead to dramatic loss of liver fat and may potentially reverse the disease.

However, there are some potential risks associated with following the keto diet for those with fatty liver disease, such as the keto flu, which is a temporary side effect that can make it difficult for an individual to continue the diet. Additionally, those with a diagnosis of diabetes may need to consult with their doctor regarding medication adjustment, as the keto diet can lower blood sugar levels.

Ketosis reduces insulin levels and insulin resistance

Ketosis is a metabolic state where the body uses fat instead of carbohydrates for energy. Ketosis is achieved when less than 50 g of carbohydrates per day are introduced, with either restricted or unrestricted fat and calorie intake. Ketosis reduces insulin levels and insulin resistance by decreasing intestinal absorption of monosaccharide, which leads to lower blood glucose levels and reduces the fluctuation of blood glucose. Ketosis also increases the rate of fatty acid breakdown, or their oxidation rate, reducing oxidative stress and helping to reduce inflammation and irritation in the liver.

Ketosis reduces lipogenesis

Ketosis is achieved when less than 50g of carbohydrates are consumed per day. This results in a decrease in insulin levels, which in turn reduces lipogenesis and increases the rate at which fatty acids are broken down (or their oxidation rate).

Ketone bodies are produced in response to carbohydrate restriction and have been proven to induce satiety, leading to a reduction in food intake and weight loss.

Ketone bodies have also been linked to the inhibition of inflammasomes, in particular NLRP3, a key signalling platform that activates pro-inflammatory cytokines, such as IL-1β and IL-18, which are strongly associated with obesity and the pathogenesis of insulin resistance and type 2 diabetes.

In addition, ketone bodies have been proven to induce satiety, leading to a reduction in food intake and weight loss.

Ketosis reduces oxidative stress and inflammation in the liver

The ketogenic diet is a high-fat, low-carb, moderate-protein diet that produces metabolic changes similar to those seen in a state of starvation. This diet has been shown to be effective in treating refractory epilepsy in infants and children, as well as in weight loss and diabetes management in adults.

The ketogenic diet works by altering energy metabolism. After three to four days of fasting or following a very low-carbohydrate diet, the body becomes deprived of dietary sugar and starch, and reacts by reducing insulin secretion and switching to primarily burning fat for fuel. This process, known as ketogenesis, leads to the formation of ketone bodies (acetoacetate, acetone, and beta-hydroxybutyrate) in the liver. These ketone bodies can cross the blood-brain barrier and provide an alternate energy source for the brain.

The ketogenic diet has been found to reduce insulin levels, increase fat oxidation rates, and reduce lipogenesis. Insulin is known to promote the conversion of excess glucose to fat, so by reducing insulin levels, the ketogenic diet can help prevent fat storage in the liver. Additionally, the ketogenic diet can lead to a gut microbiota shift that induces folate production, which can help ameliorate lipid metabolism and limit oxidative stress and inflammation in the liver.

The ketogenic diet has also been shown to increase the level of mitochondrial uncoupling proteins (UCPs), which are involved in several functions that protect mitochondria from oxidative injury and dysfunction. Furthermore, ketosis can activate several key factors involved in liver-protective activities, including SIRT3, PGC-1α, and NRF2, which enhance antioxidant defense and reduce oxidative stress.

Overall, the ketogenic diet has been found to alleviate oxidative stress and restore mitochondrial function in the liver, making it a promising therapeutic option for nonalcoholic fatty liver disease (NAFLD).

Ketosis suppresses appetite and promotes weight loss

The ketogenic diet is a popular choice for people looking to lose weight. Ketosis is a metabolic state that occurs when your body burns fat for energy instead of glucose. During ketosis, the body becomes very efficient at burning fat and using it for energy.

Ketosis suppresses appetite

Ketosis appears to suppress appetite. Individuals adhering to a ketogenic diet are less hungry and have a reduced desire to eat. This is due to the release of cholecystokinin, which reduces orexigenic signals.

Ketosis promotes weight loss

Ketosis can lead to weight loss in several ways. Firstly, ketosis can help you feel less hungry, which may lead to eating less food. Secondly, ketosis can help you lose belly fat while maintaining lean mass. Thirdly, ketosis increases the rate at which fatty acids are broken down, reducing oxidative stress and inflammation in the liver. Finally, ketosis can be induced by a low-carbohydrate diet, which can help reduce insulin levels and lipogenesis.

Ketosis improves heart health markers

Ketosis is a metabolic state in which the body uses ketone bodies, produced from fats, as its main source of energy instead of glucose. Ketosis can be achieved by following a ketogenic diet, which is a very low-carbohydrate diet.

Ketosis has been shown to have a positive effect on cardiovascular health markers. A study by Virta Health found that 22 out of 26 markers of cardiovascular disease risk improved in their patients, many quite significantly. However, there was an exception: LDL cholesterol went up a little bit on average.

Another study found that the ketogenic diet had a beneficial effect on blood pressure and other cardiovascular risk factors through weight loss.

The ketogenic diet has also been shown to have a beneficial effect on the blood lipid profile, even compared to other diets. It also shows strong anti-inflammatory and cardioprotective potential, which is due to the anti-inflammatory properties of the state of ketosis, the elimination of simple sugars, the restriction of total carbohydrates and the supply of omega-3 fatty acids.
