carb foods. On the set, a bucket was set up where the actors  would spit out the food so they wouldnt take in the carbs. David  Cross, who didnt use the bucket, noted the irony that although the  characters saw through the hype of the fad diet, the actors playing  those characters had not. However, actors often use spit buckets for  scenes in which they must eat a lot of food to avoid making  themselves sick doing multiple takes.
