Earlier this week I posted a blog entry noting that I'd been dragging. Had that heavy, body-feels-like-dead-weight and head-is-filled-with-molasses (cliches, anyone?) feeling. I'd pretty much written the condition off to a change in the weather, with heavy heat and humidity finally coming in, combined with an increase in my exercise intensity.

My best friend Trisha called today and said she'd been thinking about it and wondered if my new plant-based diet had anything to do with my recent tiredness.

"You know, I hadn't made that connection," I said. "I guess that could be it."
