Brissette agrees with this line of thinking. As you can see, there are many potential benefits and side effects of the ketogenic diet. This may be related to the fact that protein alone is less effective for muscle building than protein and carbohydrates together after exercise. Yet the folks on keto did lose more leg muscle. Falls are the top cause of death from injury in older populations, according to the Institute of Medicine Division of Health Promotion and Disease Prevention.
Kidney stones are a well-noted potential side effect of the ketogenic diet. Research published in the Journal of Child Neurology observed that among children following the keto diet as a treatment for epilepsy , 13 out of subjects developed kidney stones. Children supplementing with potassium citrate in the study noticed a decreased likelihood of kidney stones. Speak with your healthcare practitioner about supplementing if kidney stones are a concern.
And the ketogenic diet can be dangerous for people with kidney disease, as people with kidney disease need to follow an individualized diet as prescribed by their doctor. Carbohydrates help control blood sugar levels, which are of particular importance for people with diabetes. A study published in May in the journal Diabetic Medicine shows that while a keto diet may help control HbA1c levels a two- to three-month average of blood sugar levels , the diet may also cause episodes of hypoglycemia , which is a dangerous drop in blood sugar.
The same goes for people with type 2 diabetes. For example, a study published in September in the journal Nutrients highlights the importance of whole grains for helping to control weight as well as episodes of high blood sugar. Whole grains are off-limits on the ketogenic diet. Axe says that, when done right, the keto diet includes lots of vegetables and lean sources of animal protein.
Doctors say that high-fat diets like this one may raise cholesterol levels, and some studies suggest that they increase the risk of diabetes. Just this week, a 25,person study presented at the European Society of Cardiology Congress in Munich suggested that people on the lowest-carb diets had the highest risk of dying from cancer, cardiovascular conditions, and all other causes.
Another study , published this month in the Lancet , also found that people who followed diets that were low in carbs and high in animal proteins typical of the keto diet had a higher risk of early death compared to those who consumed carbs in moderation.
The opposite was true, however, for low-carb dieters who opted for plant-based proteins over meat and dairy. To get our top stories delivered to your inbox, sign up for the Healthy Living newsletter.

As well as contributing to weight loss , ketosis may have several health benefits , such as reduced seizures in children with epilepsy 2.
Glucose blood sugar is the preferred fuel source for many cells in the body. Ketosis is most often associated with ketogenic and very low carb diets. It also happens during pregnancy, infancy, fasting and starvation 3 , 4 , 5 , 6.
For ketosis to start, you generally need to eat fewer than 50 grams of carbs per day and sometimes as little as 20 grams per day.
However, the exact carb intake that will cause ketosis varies between individuals. When eating a very low carb diet, levels of the hormone insulin go down and fatty acids are released from body fat stores in large amounts. These molecules can provide energy for the body. Unlike fatty acids, ketones can cross the blood-brain barrier and provide energy for the brain in the absence of glucose. Ketosis is a metabolic state where ketones become an important source of energy for the body and brain.
This happens when carb intake and insulin levels are low. However, a large portion of your brain can also use ketones for energy, such as during starvation or when your diet is low in carbs 7. In addition, your body can use protein or other molecules to produce the glucose the brain still requires during ketosis.
This process is called gluconeogenesis. The glucose it still needs can be produced from protein or other sources. While ketosis is part of normal metabolism, ketoacidosis is a dangerous metabolic condition that can be fatal if left untreated. In ketoacidosis, the bloodstream is flooded with extremely high levels of glucose blood sugar and ketones. Atkins popularized his very-low-carbohydrate diet for weight loss that began with a very strict two-week ketogenic phase.
Over the years, other fad diets incorporated a similar approach for weight loss. In essence, it is a diet that causes the body to release ketones into the bloodstream. In the absence of circulating blood sugar from food, we start breaking down stored fat into molecules called ketone bodies the process is called ketosis. Once you reach ketosis, most cells will use ketone bodies to generate energy until we start eating carbohydrates again. The shift, from using circulating glucose to breaking down stored fat as a source of energy, usually happens over two to four days of eating fewer than 20 to 50 grams of carbohydrates per day.
Keep in mind that this is a highly individualized process, and some people need a more restricted diet to start producing enough ketones. Because it lacks carbohydrates, a ketogenic diet is rich in proteins and fats.
