The closest I have ever gotten has been dropping the vast majority of my red meat and pork consumption and upping the fish. A patient had inquired about the diet
Eat Right for Your Type
and I do not comment to my patients on things I have not been willing to try myself or products I do not personally own.
So basically my blood type is a big fish consumer. Red meat accelerates the aging process according to the diet and so I did a modified fast/detox program that we take groups of patients through occasionally. After that I began to eat fish for the first time ever in 30 years. It took a little bit to get used to but now, outside of hamburgers, I couldn't tell you the last red meat I have eaten. Outside of sausage I haven't had any pork steaks in awhile either. For the few months I was eating a pure fish/chicken/veggie healthy diet I felt good and some inflammatory processes I recognize in my body were absent.
Now I eat way too much other crap and need to actually take myself back through that program and get back into better shape.
