The Paleo Diet recommends 55% of calories per day. That's about 1.5lbs of lean ground beef. Are you all really eating that much meat a day? That must be crazy expensive. It also has ~130% of your RDA of sat fat and ~150% of your RDA of cholesterol. I guess it looks a lot better for Sirloin. What about chicken and turkey? I'm not accustomed to cooking and eating so much meat.
You don't have to eat a specific amount of meat, just make sure to get enough protien. 80-100g is a good start, possibly more if you are athletic. The paleo diet book isn't that great for nutritional info, you'd be better off reading some marksdailyapple blog posts or searching around paleohacks.
I've been known to eat a 1lb steak for dinner, but I probably average about .75lb-1lb per day. Like Cliff said, don't worry about eating a specific amount of meat (I also wouldn't put much stock into the RDAs for fat). Play around with different amounts & see what works best for you, as far as how you feel and what you can afford (and there's a lot of good info out there about making this work on a budget; it doesn't have to be expensive). Good luck! :)
I do CrossFit 3x per week and a day of heavy lifting. I am 175 and generally aim for around 120-150 grams per day and that has seems to work pretty well as far as gaining muscle and strength goes. If I didn’t do all that, I would go for 80-120 grams per day. That’s just me :)
