Absolutely, a keto diet can be unsafe if not done properly but if done properly, it is not unsafe.

The correct ratio of protein, carbohydrates and fats must be followed.

One completed study concluded that a keto diet is safe and effective, particularly for obese folks.

NIH study:

The present study shows the beneficial effects of a long-term ketogenic diet. It significantly reduced the body weight and body mass index of the patients. Furthermore, it decreased the level of triglycerides, LDL cholesterol and blood glucose, and increased the level of HDL cholesterol. Administering a ketogenic diet for a relatively longer period of time did not produce any significant side effects in the patients. Therefore, the present study confirms that it is safe to use a ketogenic diet for a longer period of time than previously demonstrated.

More studies in the very early stages:

"The basic premise for using the ketogenic diet is that this therapy may provide neuroprotective effects in a very broad manner," explained Rho .

Results are early and often anecdotal but are impressive in their sheer range of applications. Migraines, thought to be caused in part by an energy deficiency disorder, responded favorably to ketone supplements in a preliminary study.
