low carb/keto website resources

I too am looking for low carb/keto resources. I find this very difficult to do; however, about three years ago. I lost a lot of weight by this radical method of eating. I did not feel as terrible as I do right this minute, with just cutting calories. My energy is a real problem. So I would like some online resources as well.
