ketone diet is safe

Although the ketone diet is safe for people with no health problems, it is possible that you feel some side effects while your body is still adapting to the new diet. This is relatively common and goes on in a few days (https://fitcrasher.com).

Common side effects include: feeling weak and tired (including mental), increased hunger attacks, difficulty sleeping, bowel problems, and reduced athletic performance. This can teach your metabolism to gradually adapt to using fat as a primary energy source before you dive headfirst into DC.

To alleviate these side effects, it pays to start with a normal low carb diet before attempting the ketogenic diet https://fitcrasher.com (one that allows you to consume carbohydrates in the range of 50-150g per day).
