Ken said that he is going to reduce the number of calories that he eats during the day. Ken's trainer asked him to start off small and reduce the number of calories by no more than 7%. Ken decided to consume 2.200 calories (recent) per day instead of his normal 2,500 calories per day (original) until his next visit with the trainer.
