I have a "big ass salad" rule...must eat BAS first, then see. I fast through breakfast and lunch and noticed I got off on the wrong foot if I reached for nuts or cheese first at dinner time. But meat is more self limiting IME, and sometimes, like last night, the brisket comes out the oven and I just dig in and quit when I'm full. I figure if you're craving meat there's a good reason...so I wouldn't get too hung up on some arbitrary portion size. Letting natural hunger do its job is one of the perks of Primal living, tho there are still danger areas to watch for.
