If you want to start protein diets and if you are not sure you can take a look that alternatives: Ketogenic diet, paleo diet, low carb diet, atkins diet... But before you start you should know all these diet types and then you can start your diet..
Actually ketogenic diet is same like paleo, even i was knowing ketogenic and paleo are same diet type and lists.. But keto is a little different type for nutrition. I found an article about "which diet better for you" paleo or keto: http://ketogenicdietmenuplan.com/ketogenic-vs-paleo/
