For most people, the ketogenic diet will optimize your blood pressure and cholesterol levels. When it comes to cholesterol, you will most likely experience an increase in healthy cholesterol HDL that will help prevent heart disease. In other words, if your cholesterol levels go up while you are on the keto diet, this is usually a good thing. To learn more about what happens to your cholesterol levels on keto and how to interpret your cholesterol numbers, check out this article. On the other hand, if you have familial hypercholesterolemia, then increasing your fat intake will most likely cause your cholesterol levels to rise in an unhealthy way. In this case, you will usually do better with a lower fat diet. Regarding blood pressure, keto seems to decrease it more than any other diet that has been studied. A low-carbohydrate diet incorporating fats from olive oil along with vegetables and fish characteristic of the Mediterranean Diet may be the best diet for lowering blood pressure.

A Michigan Medicine dietician explains how the popular low-carb regimen can get results — as well as related risks everyone should know. Touted by celebrities as a quick way to lose substantial weight, the ketogenic diet might seem counterintuitive to good heart health. Fruits, root vegetables, grain products and legumes all are prohibited. The intake is designed to trigger the metabolic state of ketosis, a process that occurs when the body burns off fat as an alternate source of energy. A keto diet can also lower elevated blood sugar linked to artery-damaging inflammation. Proteins comprise 20 percent — and carbohydrates make up just 5 percent. Cutting out low-quality carbs found in soft drinks and white bread, for instance, is a good idea for anyone, Ryskamp says. Sugar and starches raise the risk for obesity, diabetes and heart disease. Healthful, too, is a steady intake of green vegetables such as broccoli, celery, kale and spinach — all of which are permitted on the keto diet.
Back to Food and diet. The headline refers to the increasingly popular ketogenic diet. This diet involves eating a combination of high-fat and low-carbohydrate foods. As the body usually uses carbs for energy, the diet is designed to “force” the body to burn off fat instead as an alternative energy source. This can help promote weight loss. But it’s not accurate to describe the high-fat diet used in the study as a “keto diet”, as it consisted mainly of lard and rodent feed or chow and was higher calorie than the normal-fat diet used in comparison. The researchers said the rats used in the study Dahl salt-sensitive, or DSS, rats were bred specifically to show an increase in blood pressure in response to diet, and that the 4-week response to a high-fat diet “appears to be unique to DSS rats”. When it comes to a healthy diet, weight loss is not the only concern.
I think that diet is important, and I have a personal interest in many of these approaches to nutrition, but what I share with patients is mostly my informed opinion based on as much science as possible. The main issue is that ketosis is arguably a backup mechanism for fuel and energy for the body, he says. Higher HDL cholesterol levels and lowering blood sugar are also associated with lower risk of heart disease.
