We've all heard the old adage "cheaters never prosper." But when it comes to following a healthy diet to lose weight or maintain your current weight, do cheaters prosper? Some diets allow for certain "cheat" meals or entire "cheat" days, so this concept is not new. There are smart ways to occasionally indulge without throwing your diet completely off track. But be careful not to be too restrictive on certain days and binge on other days as this creates unhealthy eating habits that can spiral out of control.

First of all, the idea of cheating implies that certain foods are off-limits or should be demonized. What's important to remember is that a healthy diet is comprised of many different foods. Really, there are no "good" or "bad" foods, and nothing should be off-limits. Certainly there are specific foods that we want to choose less or more often, but labeling foods as "bad" or labeling foods that, if consumed, make us feel like we're cheating, can lead us into dangerous territory of negative talk around food. This can spiral into disordered eating. An eating plan based on shame and guilt is both unhealthy and hard to maintain. But more than that, a restrictive diet is mentally draining and takes the pleasure out of eating.

With that being said, there are certainly ways we can indulge in those rich, once-in-a-while foods without going overboard on calories. When it comes to weight control, it all boils down to calories in versus calories out, meaning you must balance the calories you take in from food with the calories you expend during physical activity and basal metabolism in order to maintain your current weight. If you are looking to lose weight, you need to create a calorie deficit by taking in fewer calories than your body uses in a day. As long as you don't go over on your calorie level (based on whether you're looking to lose or maintain weight), you can allow for certain treats here and there.

The key to occasionally indulging is to be sure to allow for it in your daily calorie budget. Keeping a food journal is one of the most successful strategies dieters can employ. Research has repeatedly shown that people who log their food intake and exercise lose twice as much weight as those who don't keep food journals.

One way to approach this is to think of your daily calorie needs as a bank account. You "withdraw" your calories throughout the day as you choose your meals as snacks--much like you'd withdraw money from you bank account for whatever purchases you choose to make. At the end of the day, if you still have calories in your budget, you can choose to spend those calories on whatever you'd like. In the same vein, some people prefer to bank extra calories each day of the week in order to splurge on a specific meal or an entire day later on in the week. As long as your diet isn't so restrictive throughout the week that you feel deprived and overindulge on your cheat meal or cheat day, banking extra calories throughout the day or week for your choice of a treat food should be safe.

Just remember--moderation is always important. You should never consume fewer than 1,200 calories per day or you run the risk of causing a number of metabolic abnormalities.
