Can You 'Cheat' on Your Diet and Still Lose Weight?

How Cheat Meals and Cheat Days Affect Your Weight Loss

"Cheating" is the act of deceiving others or being dishonest. The word conjures up images of copying someone else's answers during an exam, fudging your taxes, or counting cards.  Needless to say, these are not positive activities.  But does the same negative connotation apply to a cheat meal (or day) for a person on a diet?  Can "cheating" on one's diet be beneficial—even fun—or is it just setting the stage for dieting disaster? 
 
As a registered dietitian, I am often asked about cheat meals and cheat days.  Usually the dieter seems to be asking the question out of desperation. He or she often mentions feeling obsessed and exhausted of counting calories. "I want to have a cheat day once a week where I can eat whatever I want without worrying about my calories," they often say.  "But will this cheat day hurt my weight loss?" In other cases, people eat so "clean" (i.e. perfect) on their diets that they simply can't keep up with it day in and day out. They feel that they "need" a cheat meal or day to look forward to and keep them accountable to their strict diet all the other days.
 
I think everyone would agree that even though it has been documented to help people lose weight, daily calorie counting is a big pain in the butt.  You have to read labels, measure portions and keep track of so many details. Food selection is constantly on your mind.  Focusing so much on calories makes it easy to get into the trap of trying to eat a strict diet of "good" foods, then falling off the wagon and overeating the "bad" foods you tried to avoid.  Your vocabulary and thoughts are consumed with extremes: good foods vs. bad foods, cheating vs. being good, restricting vs. overindulging. It is easy to see why you'd want to "cheat" on a system like this. But is cheating on your diet really the answer?
 
Scientifically speaking, "cheating" has not been studied enough for me to give you a clear-cut answer on whether or not it works in the short-term or the long-term.  However, the science of caloric intake, as well as the psychological implications of cutting and counting calories, has been extensively researched.  So let's explore what we do know and apply it to the idea of cheat days.

"Calories in vs. calories out" is the golden rule for effective weight loss. To lose weight, a person must eat fewer calories than he or she burns.  Let's assume you are cutting a total of 3,500 over the course of a week to lose 1 pound.  In this example, your daily calorie intake is about 1,200-1,500 calories. (Calculate your daily calorie needs for weight loss here.) Say you choose to eat right in the middle of your recommended range: 1,350 calories per day. How would an innocent "cheat" day affect your progress?
  • Scenario #1:  On your cheat day, you indulge in a few extra sweets or treats and take in 2,500 calories total.  This brings your daily average to 1,514, which is still within your weight-loss calorie range.  Therefore, you should still lose weight for the week.
     
  • Scenario #2:  On your cheat day you eat anything and everything you've been craving: a fast food value meal, potato chips, a milkshake and some buttery popcorn. You take in 4,000 calories.  This brings your daily average to 1,729, which is over your weight-loss calorie range.  Therefore, you will probably maintain your current weight for the week.
 
This simple example illustrates how a cheat day can easily derail your weight loss efforts.  If you eat with reckless abandon and no real plan (or calorie counting), as in scenario #2, you'll stall your weight loss. But scenario #1 shows how the occasional higher calorie day can still fit into a weight-loss plan when it's properly planned and somewhat controlled.  Planning for that little indulgence on occasion is easier than you may think and uses the weight loss technique that I call "calorie banking."

  • I have always said that its better to eat smaller amounts of the 'bad' foods then to totally restircit yourself and binge out making yourself feel sick and horrible for overeating the 'naughty' foods. If i feel the need for chocolate I get a small bar and enjoy it! - 2/6/2013 11:17:41 PM
  • Great article.... I admit, I don't usually love food and when I was young, they used to give me shots to try to make me eat. I just didn't want to. Now, I usually eat the same thing every day and it makes my calorie counting easier.

    I think I am more lazy than anything else. Starting in high school, if someone put a pizza in front of me, I would eat a large pie in one sitting. My laziness was really my Achilles Heel. Now, I have my "cheat" meal since my family likes pizza once a week and I plan for it in my other meals. I also try to drink a big zero cal/caffeine free drink first so that I don't get too far out of control. One day, I'll plan it better and get a salad made in advance to keep me in check. - 2/6/2013 8:13:49 AM
  • cheating helps. just watch the people on biggest loser, they pull out big numbers after an indulgence. probably their body stops thinking it is starving - 2/6/2013 12:52:19 AM
  • Daily calorie counting is LESS a pain in the butt if 1) you eat mostly whole foods, rather than packaged (fruits, veggies, etc.), 2) you use the Nutrition Tracker (being Pescatarian, I enter my own food or meals ONCE & it's much easier) & 3) prepare SP recipes, which have all the nutrients calculated for you. - 2/6/2013 12:06:51 AM
  • Your friend, Patrick's response was powerful. It took the feeling of deprivation out of the conversation and instilled empowerment.

    I had a "Cheat Day" that was unplanned and it spiraled out of control (also unplanned), it left me broken.

    I equate the experience to driving...if I plan on getting somewhere safety I need my hands on the wheel. Just because I can drive with my knees, doesn't mean I should. - 2/5/2013 10:12:00 PM
  • I will never call it a 'cheat' day. I will call them Special Days. That allows me to have ONE day or ONE meal without the guilt. I am also not crazy about the scale right now. If I was in the mode to lose 2 lbs. every week, yep, a 'cheat' day might make me not make it. But I'm on the slow and steady lose it and NEVER find it again. and for ME to do that, I need to have a Special day every once in a while! - 2/5/2013 8:09:54 PM
  • I think that life for us all would be so much simpler if we got rid of all these negative connotations like "cheat" or 'naughty" or even just "bad".

    For example, I did something really bad the other day, and bought myself a coupe of bags of crisps.
    Now using the word "bad" could scar me.
    However, I ate some of each of the bags of crisps, that day, and thoroughly enjoyed them - having not had any crisps for about a year.
    (Sorry - crisps = chips.)
    I then had a handful of crisps the following evening.
    And now, several days later, I still have the 2 bags with at least a third of their contents.
    I had something that I really fancied, that was not in my diet plan for the day. I didn't beat myself up about it, just let myself really enjoy the novelty. And I have the remainder there - had some the second day, and I'm not needing any more just yet.

    So I didn't and I don't feel naughty. I don't feel that I've cheated - the only person I can cheat is me, and I gave myself permission to enjoy. I didn't let myself feel negative about eating "bad" stuff. I even bought myself some dips just to make sure that i enjoyed my time out. I can't say that I will eat any dips like that again for a hugely long time - the tray went into the bin later that night, with at least half the contents still in it. But I enjoyed my wee binge, and I remembered why I don't do it any more, because the dips are so full of all the stuff I have rarely eaten in years - like chemicals.
    Yes, my evening will have had an effect in my journey. But it is a positive effect, because (a) i enjoyed myself, for a small increase in stuff, and (b) I was reminded why I don't eat some of these things any more.

    Negative ideas lead to more negativity. That is something we in SparkPeople do not need.
    So pleasde - let's cut the negative comments and concentrate on the positive. - 2/5/2013 7:41:11 PM
  • Another generalist article, it gives one scenario for "cheat days" there are others and they do work , not for every body, not for people who have a hard time with food choice but Ive used a "cheat day system for along time and no I do\nt eat 4000 calories but i do eat pizza or roast chicken or what ever I feel like usually higher fat content. Its about Leptin levels. I also watch my calories for the week not each day and rotate hi and low carb days and have a hard training day the day after where my food intake is usually lower and supplemented... if those kind of things appeal there are grat ways to lose and maintain low %BF - 2/5/2013 5:31:29 PM
  • Never mind the downhill spiral it can set you on for several days after. We didn't get fat by being able to stop....... - 2/5/2013 3:08:14 PM

    This whole article was not what I would consider when talking to my team about cheat meals or cheat days. This article revolves around a cheat being based on how many calories are in it and does not take into account what you are actually eating. A cheat is when you eat something that goes against your goals. That could be a 50 calorie cookie just as much as a 800 calorie fast food meal out. In both cases, you will end up with empty calories that won't help your goals and both are a cheat even though the cookie wont effect your calorie count much for the day.

    It seems the better option would be to have a number of cheat meals in your calendar. I plan 42 meals in the week (3 meals, 3 snacks per day) and 2 to 3 are cheat meals. That may or may not mean they are bad for me. But they mean I won't include them in the NUTRITION plan for the week. Everything I need to make my goals is in my plan. Those 2 or 3 are wild cards. They might still be healthy or might not. Maybe it is a church dinner, or the movies, or meal with a client.... whatever. But I know they are wild cards because I am not making the meal... so I plan for it. - 2/5/2013 2:22:59 PM
  • I think the key here is what is a cheat day. If it is a 3000 calorie splurge every week, it would probably quickly derail my efforts. Everybody needs to decide what that term means to them and assess how it will affect them. I try not to think of my current journey as being on a diet but as a life style change. I have gone through most of our favorite meals and lightened them up as much as possible. If we are having a heavier meal, I try to lighten up breakfast and lunch that day. Or I may lighten up the day before and the day after. I find for myself, I need to track or I can quickly get off track. I have found some great recipes in SparkRecipes that I have make, but by incorporating some of the old favorites (lightened up if possible) into my meal plans it helps to me to feel as if I am not depriving myself. I know my key is the planning and tracking, as long as I do that I am fine. - 2/5/2013 1:12:17 PM

    Very good article, but I have some doubts about the concept of "banking" calories for future use.

    There is a theory that says that, to an extent, we spend pretty much as many calories as we consume. That means that on days when we consume fewer calories, we are more likely to be less active. On days when we consume more calories, we tend to be more active.

    We all have seen the extra energy being burned off by children, right after they eat something that contains sugar. We wouldn't burn off a 3000 calorie meal that way, but if we talk about the range below 1500 calories per day, the theory seems plausible.

    I am not sure that calorie intake versus expenditure works on a 7-day cycle rather than day-by-day. So, I prefer not to "bank" on banking calories to allow for a binge. - 2/5/2013 1:00:38 PM
  • I think this is a great article--a great perspective on cheat days!

    I've recently been having days where I cheat on tracking--I eat as I would any other day, but I don't worry about tracking it all. This works for me, and the joy in it is that I get a day off from thinking so hard about what I'm eating. - 2/5/2013 12:06:39 PM
  • Love this one! I needed this today as I've had that negative mindset for the last few weeks. Time to get it into perspective and move forward. - 2/5/2013 11:04:04 AM
