New to Keto/low carb/High fat. And of course this app.

I'm GF, so eat clean mostly, but really want to focus on this way of life.  It's been a bit confusing f for me trying to understand d macros. I've looked for this information and done calculations but they all come up so very differently. Do you all customize your own or use what carb manager suggests?

Looking forward to lots of guidance and peer support and those whom I can also help along the way.
