Blogspot blogger says. I gave up Diet Coke this Fall because I told my cross country team that I didn't want them drinking any soda during the season (we call it "pop" in Michigan, but I guess we're actually the odd ones in that regard) and that I would give up drinking Diet Coke so that I was giving up something too. It turned out to be easier than I thought and I do feel much better but I don't know if it contributed in any way to my weight loss or not. I just figured that all those chemicals on a daily basis couldn't be a good thing. I've replaced the daily Diet Coke with Naked brand "Green Machine" or Odwalla "Superfood" smoothies (in spite of seeing Soylent Green in the '70's) or those little V8 V-Fusion juice blends. I feel quite virtuous about this too. I feel like I'm doing my body a favor. So that IS one thing I neglected to mention last time. I doubt I could measure speed gain in my next race from quitting Diet Coke but it sure can't hurt. Plus it made my daughter happy.
