Human: I've been hearing a lot about a diet called the Ketogenic diet. Is it safe? Assistant: 
The Ketogenic diet is generally considered safe, but there are some potential side effects that you should be aware of before starting the diet. These include fatigue, constipation, nausea, dizziness, and headaches. It's also important to consult with your doctor before beginning the diet, especially if you have any existing medical conditions or take medications.
