I'm eating a lot fewer veggies and fruits, far more meat and eggs, and I feel much more energetic, very noticeable. I'm inching my way, potentially, into the carnivore diet. I'm also immersing myself in some of the contrarian books on the topic.

For a takedown of veggie "superfoods", you might find the book Toxic Superfoods interesting. Quick summary - oxalates (and other compounds in plants) can cause serious health issues over time, and acute health issues for some people. This is especially a problem with some of the plant products regarded as superfoods, especially spinach, almonds, and chia seeds. Those are some of the worst in oxalates, and I've eliminated them completely from my diet.
