These aren't 'small and quirky', but certainly unexpected. (I'm not sure we can attribute all of the changes we see posted here to the Paleo Diet. Perhaps other explanations---overall improved lifestyle/behavior that comes along with Paleo eating? However: I don't care, I'm not going back to eating SAD, ever):
-I used to get terrible hand/wrist numbness from using the mouse/key board while working. Since going paleo (March 2010), hand wrist/numbness = gone, no pain, no numbness...just incredible. No change in work load, work environment, etc. If anything, the work load has increased.
-Huge change: Seasonal fall allergies (and allergic reactions in general) way down. We had a particularly wet Spring, Summer and Fall where I live so I was expecting an absolutely horrendous Fall allergy season (I've had Falls where I was barely functional/held upright by large doses of medications and dealt with sinus and ear infection after sinus and ear infection)...this fall, nothing, clear as a bell on minimal (and reducing) amounts of medications...the allergy problem is something that I've been dealing with since I was 2 or 3 yeears old (I'm now 43).
-My wife, who's allergies are worse than mine and is only 'partially' Paleo (still hanging onto that morning bowl of 'Super Colon Blow'---not sure anyone remembers the old SNL skit?), reports the same thing: allergies (that have caused not just suffering for her, but life threatened visits to the ER) way down.
-Oh ya: I also dropped 38 lbs and added a bunch of muscle without having to kill myself to do it.
43 is the new 23 by living Paleo
