I'm not sure why you're getting downvoted. Because you eat solely meat?
I'm on keto, but I use DIY Soylent and vegan protein sources for it. Not because I don't like meat (I LOVE bacon), but because I'm lazy.
Keto is wonderful because it keeps your blood sugar level low, which helps burn fat and prevents your body from storing excess energy as fat. Don't overdue the red meat though; there is a body of evidence that shows that red meat can cause cancer through the digestive track.
Also, much love for /r/keto. It's a wonderful community. Keto on!
