The Keto diet is safe for healthy adults. If you have an acute or chronic illness, you should consult your doctor on whether or not the ketogenic diet is suitable for you.
Is the Keto diet suitable as a permanent diet?
We do not recommend the ketogenic diet as a permanent or long term diet, since the risk of nutrient deficiency due to a unilateral food selection should not be underestimated.
If you decide to follow the Keto diet for more than a few weeks, we suggest to have your blood values checked regularly by a doctor.
