I started the Paleo diet about two years ago because the low-fat vegetarian thing that I’d been for twenty years just wasn’t working. Within three weeks, I’d lost three dress sizes (not so many pounds, but who’s counting), and my muscle tone had visibly improved. But the most amazing change was in my personality and health. It was as if someone had lifted a dark veil from my head. I sleep less but better, wake up happy, and look forward to my daily challenges. My hair loss and skin problems have vanished. My teeth are stronger, and my gums don’t bleed. My thyroid (which I claimed was enlarged, but doctors disagreed) has gone back to its normal size. I could go on and on.
