One of the most common question I get when people find out I am on a ketogenic diet is if I am not scared of all the risks with a ketogenic diet. I hear several times per week about how dangerous a low carbohydrate diet is and that there are so many ketogenic diet risks. I always try to explain to them that of course there are risks and dangers with a ketogenic diet but there are risks and dangers with all diets. In order to better beeing able to explain to my friends what the actual science is around the ketogenic diet risks and if there is any actual proof I researched a little on the subject.
The main ketogenic diet risk that people bring up is that it is so easy to get a heart attack or other heart problems with a ketogenic diet. The research report that this is based on is a report from a research done at a Hospital where they treated children. The children that were eating according to a ketogenic diet were doing so since they were having seizures. The ketogenic diet is known for helping children who are having seizures. At the hospital they noticed that one of the child was having heart problems so they started a check on all the children eating according to a ketogenic diet. They found that 15 percentage of the children had some kind of heart problem. The problem with this study is that they did not know if these children had the heart problems already before they started with their ketogenic diet or if it was caused by the ketogenic diet.
Another common problem mentioned is that people will have headaches, liver problems, dizziness, nausea or other similar problems. This mainly comes from two separate studies about the ketogenic diet risks. One of the studies was performed in Korea and the other is from Epilepsy.com. Both do only show risks during a short term usage of a low carb diet and does not really show the effects during a longer time using a ketogenic diet.
There are also several positive research studies about the ketogenic diet and how it can help with the treatment of cancer. These studies are however quite few and very little research has been done in the area.
