What is the highest source of raw protein for us carnivores?

I will at some point transition to a more raw diet. I want to drop over 100 lbs, am a diabetic and as of yesterday started, um RE-started, an exercise regime.

Along with this, I will be doing a parasite cleanse 3 weeks from now. It's 3 weeks from now as I am starting a new job and that's after my first paycheck.

Would it be better to do the parasite cleanse before going more raw or does it matter?

And I am concerned about protein in my body as I drop weight and work out.

Thanks!
