Keto diet

I started a keto diet this week. Today is day 5 of me being on it. I've had salads for some days but on those days I felt like I was constantly hungry. On one of the days I had eggs with chorizo, avocado, and cheese and I was full almost all day. Can anyone give me advice. I get really hungry when I eat the salads and i snack on things but they only satisfy my hunger for maybe half hour or so.
