I am pretty much 98/2 when it comes to compliance, not because I'm OCD but because this is where I feel right physically. The 2% is for social situations where the ingredients are out of my control, not for intentional "cheats".
Low carb (you could have another whole poll about the definition of "low" and "very" when it comes to carbs)
Absolutely no grains
No added sweeteners, real or fake
No processed foods (I don't eat bacon, Primal heresy, I know)
Minimal/infrequent tubers, no white potatoes
Moderate fruit mostly berries, occasional banana
Only butter (some people don't think that counts as "dairy", others do)
No nasty oils
Lotsa meat, mostly ruminants, all grass fed and finished, nose to tail
Lotsa seafood and sea veggies, wild caught and organic
Lotsa veggies, salads, organic and often homegrown
A few nuts, mostly macs but limit quantity due to calories
100% cocoa chocolate now and then
A *very* occasional glass of red wine
I have done the n=1 with "safe starches" and dairy and they don't do anything but put pounds on me.
