I'll have a small helping of chicken perhaps once a week and less frequently fish. I very seldom eat beef or pork, though. I get what little protein I need primarily from a protein shake, but I don't overdo it on protein. 50gms/day for my body size is adequate.
My diet consists primarily of raw veggies and nuts, with a decent helping of sweets to satisfy my cravings. I avoid processed foods like the plague. I do go off the wagon eating out about once a week -- but usually salads.
It's a crazy diet, I know. But unlike most people, I eat to live, not live to eat.:-)
I actually started this diet regimen seven years ago due to low to no kidney function. It has helped dramatically. In fact, I credit it with getting me off of dialysis, with no kidney transplant, that lasted three years. It also keeps me healthy, along with a good exercise regimen (like you all).
As I say...everyone is different. Protein seems to be my main requirement...too many carbs in nuts so I cut back to pumpkin seeds only...I am playing around with my diet again. I do know as we age we need LESS calories. :*))
