Eating saturated fats can increase LDL cholesterol levels (Low-Density Lipoprotein) or often called bad cholesterol. Saturated fat is a type of fat that generally comes from animals, such as poultry, red meat, and dairy products that are rich in fat. Saturated fat if consumed in excess can increase the risk of health problems, such as increased inflammation, the formation of plaques in blood vessels, and insulin resistance. Excessive saturated fat is closely related to the risk of heart disease, stroke, and type 2 diabetes. This occurs because of an increase in levels of bad cholesterol (HDL) in the blood.
However, this does not apply to followers of the ketogenic diet. Consumption of fatty foods is believed not to cause health problems. Even the more fatty food consumed, will result in a more significant decrease in body weight.
The essence of the ketogenic diet is to change the body’s metabolism which originally relied on glucose as a source of energy replaced with ketones. Glucose comes from changing carbohydrates while ketones come from the conversion of fat. This is offset by physical activity and is not merely a limitation of calories that enter the body.
In the book The Cholesterol Myth: MI Gurr and Uffe Ravnskov refute the Lipid Heart Disease theory from Keys, which states that serum cholesterol from high saturated fat causes atherosclerosis, increased blood cholesterol and heart disease.
Cholesterol Facts and Myths
|Eggs contain a number of cholesterol which causes heart disease Eggs to increase good cholesterol (High-Density Lipoprotein) and are not related to the risk of heart disease.||Eggs are rich in protein, biotin, essential fats, vitamins, minerals and other nutrients for the brain and the whole body.|
|Total cholesterol and LDL are indicators of heart disease attacks.||The indicator of a heart attack is far more complicated. Total cholesterol also includes HDL and LDL. Divided into good LDL subtypes (large LDL particles) and oxidized (small LDL particles). Too low cholesterol is also associated with an increased risk of death such as cancer and suicide due to depression.
According to Gurr MI and Uffe Ravnskov humans can still tolerate cholesterol if triglyceride levels are maintained below 100 mg/dl. So they argue that saturated fat increases cholesterol levels. As long as the levels are maintained, it is legitimate to consume high-fat foods.
