Bodybuilders eat a Spartan diet when they train for competition. Low fat, low carbs, and overall low calories become critical to get both body fat and water weight way down. Without such dietary discipline, a bodybuilder wouldn't be as lean as he/she needs to be to win. The day after taking a prize, however, going back to normal eating is fine. Many even choose to splurge on sweets since their next competition could be months or more away.
