I had planned a "carb day" a few weeks ago because we had expensive tickets to a wine festival. As the time drew closer, I got really nervous. I ended up eating a perfectly legal dinner, having some wine but sticking with dry red, and the only thing I did have that was out of what I usually eat was 2 Stella Artois at the hotel bar after. I didn't even come out of ketosis. And I felt better than any pasta dinner and crappy dessert.
