Here is a little information to help explain bodybuilding "cheat days" and "cheat meals", and how bodybuilders view the subject a little differently.
Bodybuilders look at "cheat meals" in different ways. To some, this term simply means eating a little more than your regular portion of the same healthy foods you eat all the time. For example, if you normally eat 1 cup of cottage cheese along with 8 oz. of chicken, you may want to add a 1/2 cup of cottage cheese and a little more chicken.
To others, "cheat meals" mean something altogether different. They see this as one cheat day per week (or every two weeks) that they completely blow the bodybuilding diet and eat whatever they like, whether it be McDonald's, pizza, etc. Many enjoy an occasional night out with the spouse or significant other to dine and enjoy foods they don't normally indulge in.
The most important thing to remember here is not to overdo it. If you want to dine out once a week or on occasion, it certainly won't hurt anything. Just make sure that the rest of the time you stay on a good bodybuilding diet, packed with proteins and low in fat.
Also, some people actually get into the sport of bodybuilding as a way to lose a good amount of weight and change their bodies. If this describes you and you have been subject to severe eating problems in the past, you may not want to do anything that will cause you to fall off the wagon. Bodybuilding cheat meals for you may be best kept to healthy foods, just a little more of them one day per week.
