The SOS free WFPB diet is the same diet advocated and prescribed by what I call "the disease reversal MDs" Neal Barnard, Joel Fuhrman, John McDougall, Dean Ornish, and dozens of other well known practitioners.
Brady adds some quality meat and fish, and I don't see anything wrong with that if one can keep the level under control. The article says 20% which is higher than I go, but there is no reliable science I know of that tells us optimal levels of animal product to add to the standard SOS free WFPB diet. That could be because there is little "mainstream" science centered on SOS free WFPB diets to begin with.
(I should add here that I see everything wrong with factory farming of animals. It's not just disgusting and horrific, it is, literally, killing us and the planet.)
And is it 20% meat and fish in terms of bulk or calories? The book probably gets into that, the article doesn't. If it's bulk than the calories from meat and fish go higher than 20% and IMO that gets back into the area where heart disease and diabetes begin to become problematic.
And it should be noted there are now hundreds of thousands of people who have recovered from diseases using the standard SOS free WFPB diet with no added animal product.
How does one know if they have "recovered"? Well first and foremost, symptoms disappear. Standard medical tests showing the condition go back to normal. Correct weight is easily and rapidly achieved and then maintained. And best of all you feel better than you have in a long time.
Brady is very youthful looking for his years, and his athletic performance speaks for itself. I have no doubt his diet plays a strong role in both.
The line in the article "critics point out that it’s unnecessarily complex, unsustainable in the long term, and not supported by strong science" is wrong on every point, the diet is simple and easy, very sustainable if one is using how they feel as the gauge (as opposed to how bad they want that chili dog:), and supported by a mountain of (real) science.
I am encouraged to see the basics of SOS free WFPB diet promoted by a celebrity athlete and in the mainstream. We need more of that.
