Up until about a month ago I have never used a diet cheat day when my goal was to lose weight. I had read mixed reviews and opinions concerning whether or not they were actually effective for weight loss. More often than not, when I did read a positive take on diet cheat days it was based around muscle building and not weight loss. This gave me even more reason to believe that cheating on your diet was a BAD thing. My opinion has changed.
mmm, pizza – my favorite cheat day diet food! We’ll talk more about this in just a minute.
Dieting CAN be hard work. Also, there are so many different approaches out there that it can be just as hard work to pick one. There is one universal approach though. The one thing that most diets are based around is creating a calorie deficit. After all, eating less calories than you consume is a PROVEN and undeniable way to lose weight.
In the past I have lost weight following Eat Stop Eat with great results. I could eat virtually whatever I wanted without counting calories and lose weight. Sounds good, I know. More recently though, I’ve been testing out a “new” method for losing weight. Yes, if you’ve read my last couple of blog posts you’ll know that the “new” method of losing weight that I have been following is good old-fashioned low calorie diet … I am even counting my calories.
How Diet Cheat Days Are Good For Fat Loss
To be fair, I’m not going to say that counting calories is BETTER than following Eat Stop Eat. In fact, I have still been using the ESE along with my calorie counting.
The main idea behind ESE is that you are creating a calorie deficit over the course of the week … not each day. Some days you will eat above maintenance, others you will eat well below. At the end of the week though, you will have eaten under your caloric requirement if you didn’t pig out on feeding days.
So what does this have to do with cheating on your diet every week? Instead of eating a little looser than normal throughout the week and then relying on my two fasting days to make up for some extra calories, I have been counting calories throughout the week.
The problem here is that the body adapts to living off of fewer calories. Dieting and following a low calorie plan actually makes your body less efficient at burning fat from week to week. Why?
- Your levels of Leptin decrease (lessens fat burning)
- T3 & T4 thyroid hormones decrease (slows metabolism)
- Ghrelin increases (increases hunger)
- Cortisol increases (believed to cause belly fat)
- Metabolic rate decreases
Yes, dieting is terrible. BUT, there is an solution. High fat and high glycemic carb cheat days fix everything … seriously.
You don’t have to eat “cheat foods” if you don’t want to. You can consume extra fat and high glycemic carb foods however you choose. It is important that you get enough though. For me, I’ll stick to my fav’s … nachos & pizza.
Do You HAVE To Cheat On Your Diet?
The truth is, no. Although your body does continually get worse and worse at burning fat after being on a diet, you do not HAVE to cheat on your diet to lose weight. You can stick with eating low calories and suffering through every week without let up … it is possible and many have done so and continue to do so. Your body will not completely shut down fat burning. It will come off eventually.
My question though, is why would you do so? I get it, trust me. You feel guilty after the day has ended. One or two days afterwards you start to second guess yourself, wondering if you made a HUGE mistake.
Depending upon your body’s response time though, guess what. Two or three days later you weigh LESS than before your cheat day. This is real. This actually happens. Over the course of the last 5 weeks I’ve seen this to be true EVERY SINGLE time.
Guidelines To Ensure Your Cheat Day’s Maximum Effectiveness
There are a few things that I have been doing that make my cheat day an almost guaranteed success.
Guideline #1: Don’t over drink. This is horrible news as well, I agree. Unfortunately all of the good hormonal effects that a cheat day brings on … alcohol cancels out. If you are going to over drink … skip the cheat day or you WILL gain weight.
The general consensus is that “over drinking” (as far as diet cheat days go) is more than one drink. Basically, if you can feel it at all, you’ve had too much. Me personally, I don’t drink any alcohol at all … and I am a big fan of beer. When it comes to shedding fat though, you’ve got to decide what you want more. Once you get to maintenance, beer in moderation is fine.
Guideline #2: Fast directly after your cheat day. This is actually probably less important than guideline #1 but I really like this one. The BEST day for a fast, or even a low calorie day in general, is directly after a high calorie day.
Not only is a 24 hour fast easier after having eaten all of your favorite foods and after having satisfied any cravings … it’s more effective.
Also, it helps even out the calories for the week. Say you are eating strict diet of 1,500 calories per day. Your body is feeling the pangs and you decide to reset your body’s fat burning ability and metabolism with a much deserved diet cheat day on Saturday. That bumps your projected calories up considerably.
But, if you cut out two meals and eat a good “diet dinner” on Sunday you have only added 500 calories extra to your whole week. In the end, these extra 500 calories are NOT going to stunt weight loss either.
- Monday – 1,500 calories
- Tuesday – 1,500 calories
- Wednesday – 1,500 calories
- Thursday – 1,500 calories
- Friday – 1,500 calories
- Saturday – 3,000 calories
- Sunday – 500 calories
In addition to the calories being getting leveled out for the week, you get all of the benefits of the fast. If you haven’t seen this video about the similarities in fasting and exercise check it out real quick.
Guideline #3: Don’t go to extremes! For many the thought of a CHEAT DAY means one thing … go all out. That is not the case.
While it is okay, and in fact good, to eat anything you want, don’t STUFF your face. Eat until you are full. Do not eat until you are full and then move onto your next meal because it’s something different and you want to get as much food down as you possibly can.

Very good post on an interseting subject. Nice that you made an entire post out of my question on FB, talk about quick service
Have you taken a look at Joel Marions fatloss 24/7? A major part of that program is cycling in fast days directly efter cheat days. Keep up the good work!
Thanks Jonathan! No, I haven’t checked out the book yet. So it’s a pretty similar approach to this then, huh? Cool!
Oh one more question: Do you do any type of workout to after the day after the cheat day or is the fasting enough?
On my schedule, I don’t do a workout. I usually fast on Sunday and that just so happens to be my rest day as well.
can you have cheat meals after skipping breakfast like everyday
i fast 2 times a week for 24 hours and 5 days i do only skip breakfast and eat first meal at 2pm
so can i take cheat meals every day first thing?
I wouldn’t. The main goal of a cheat day is to replenish your body after a somewhat prolonged period of strict eating. Everyday would be too much.
I can’t trust myself with a cheat day. I have used the eat stop eat program combined with calorie counting and got great results. As soon as I cheat with some thing I just want more of it. Some cheat days happen but I don’t schedule them on purpose. I do find that a fast after them gets me back to where I was.
It can be tricky, that’s for sure. Whenever I’m shooting for a goal I am pretty determined. The cheat day STILL makes me feel guilty and second guess myself … even though I know it’s a good thing. After a cheat day I’m looking forward to getting back on track. Yes, fasting days really help get you going again.
Kevin,
Great summary of another option for stripping fat. Was just wondering what sort of body fat percentage have you achieved using this method?
Niko
Hey Niko, so far I’m only down to 9% with this method but I’m still cutting. I’ll be posting some progress in a few weeks or so.
Hi Kevin
this sounds like an interesting diet strategy and I think a cheat day gives one something to look forward to.
Absolutely! I know I look forward to my diet cheat day every week. Funny thing is that I usually look forward to it being over with as well. After eating “good” for any length of time you can notice your body doesn’t really like “bad” food as much. I like it, just not my body
can your cheat day be any day of the week! I am stuck not loosing. Took me like three months to loose ten pounds. I want to loose another 20lbs but I just stop loosing weight and I am eating healthy. My diet consists of protein shakes, vegetables, chicken, fish and eggs. no carbs.
Sharon,
Your food choices sound great so, yeah … you can cheat any day of the week. My only advice would be to not cheat more than once every 7 days. I have known some guys who get away with as many cheat days as once every 5 days but I recommend every 7.
