You might be less isolated than you think. I just came back from vacation. I went hiking with some friends. Three out of five of us just happened to be on some version of this diet. One lady was about 10 years older than me (I'm 47, also) and she knew all about paleo and the science and said she didn't eat sugar or flour mostly because other things taste better. She ate grains, but she also had coconut oil and olive oil and other paleo things in her backpack. The other man also wasn't eating any flour or sugar, but he did eat grains. His wife, who wasn't with us, got him started through something called FA, one of those anonymous 12-step things. We had a great time talking about all the health changes we've experienced. Turns out that while my friends were hiking in New Mexico they went into a bakery and the owner said HE was on the diet, too! He was thinking about changing his bakery into a healthier restaurant because of all the amazing health changes he'd experienced. I think this way of eating is spreading like wildfire and that if you look around, you may find others. But for now, you might have to just get your fix with us internet people. That's how I deal with it since I don't know any real life people in my own home town on this diet and my partner is cranky and upset about this diet (even though minus the farty oat bran and margarine, it's basically EXACTLY what his stupid cholesterol diet book wants him to eat. It sucks sometimes to live with a man who'd rather win an argument than actually stop and think for a minute.)
