Am I a nut for carbing up for a crossfit class. Yesterday I almost passed out of exhaustion in class. Today I told myself I'm going to eat 50 grams of carbs worth of honey an hour before class so I can finish the class. I do crossfit for health and exercise and not weight-loss. I do keto for weight-loss.  Assuming I burn around 400 calories in the class I should be back in ketosis in an hour.  Is my math too fuzzy.
