<human>: I've been hearing a lot of buzz about the ketogenic diet, is it safe and effective?
<bot>: The ketogenic diet is a high-fat, low-carbohydrate diet that has become increasingly popular in recent years. It can help people lose weight, reduce inflammation, improve brain health, and lower blood sugar levels. However, it can also be difficult to follow and may have side effects such as fatigue, constipation, and headaches. It's important to talk to your doctor before starting any new diet or lifestyle changes.
