In my eyes, Peat is most about affecting Hormones (measurable) and Body Temp and Pulse (measurable), NOT about what you must eat. There are differences which initially don't make sense to people schooled on Paleo/Primal.
But there is ALSO a MASSIVE similarity/overlap between Paleo/Primal and Peat's stuff. I think people should spend time in understanding the differences, and testing them if they need it. That's all. The beauty of the approach is that it gives you measurable elements, not just weight/body fat % and how you feel.
The 20% difference may just be the most essential part for people who have certain issues.
From reading Peat's article about Lactate, I can now drink Milk for the first time in 3 years. All it took was to slowly introduce a small amount each day (1/2 a cup with 2 meals), and slowly taper it up, and hey presto, my supposed Lactose intolerance that I was "diagnosed" with no longer exists after 2-3 weeks!
Obviously no one diet works for everyone. There are definitely things people can learn from Peat's writing and research, which may make a massive difference to your life.
Tweak and track!
Don't be scared of fructose and milk; eat to increase body temps and pulse (if low); eat late at night with "sugar" (frustose) to offset stress hormones while you sleep; use excess salt; if waking at 4am, eat/drink sugar and salt; check your hormones, try to move them into a more optimal range with diet and lifestyle; understand exercise can affect you negatively in the long term if you overdo it
It's hardly saying drink the blood of a young child.
I also couldn't understand why hitting the gym would make me feel great, but that I was then often injured and really, chronically tired. Peat's stuff has allowed me to understand why - it's related to hormones, and understanding exercise as a stressor.
I see Peat as Primal / Paleo with a 20% difference, but people don't seem to want to learn and test whether that difference will improve their situations.
If you don't need it, cool. Enjoy Paleo/Primal, but allow other people to write about it and test it.
But remember it's there if you don't feel optimal at some stage in the future. For a long time I ignored poor digestion, freezing hands and feet, constant sore throats, poor sleep, waking at 4am, and I ignored them because I was "eating like a caveman" and losing weight while getting more ripped at the gym.
