I run circles around the meat eaters in my life. My latest change was replacing maple syrup with date sugar. I also started drinking matcha often. The change to a Whole Foods sugar made all the difference in the stability of my energy levels. Matcha also makes the caffeine buzz a lot more steady, manageable, and even calm. Changing out processed foods for Whole Foods might outweigh the carb/fat/protein differences. There’s still a lot to biology and nutrition we don’t know, in my first hand experience.
