Cheat days

Cheat day? Probably a bad idea. A "cheat" meal once a week, has helped me control cravings and keep on track the other 20 meals of the week. Still you need to keep it reasonable...ie...blowing out on 5 plates worth of food at Golden Corral will probably not be in your best interest.

Personally, no. I prefer to "treat" myself every day, as long as it fits within my calories. The only two days where I am a bit more lenient with my calories is my birthday and Christmas -and even then, those days do not become free-for-alls.

I'm not a fan of cheat days, I just eat what I want as long as it fits into my calories for the day.

I dislike the word "cheat" at all in this context. It implies that you're doing something wrong or against the rules. I treat myself with a little something every day and I build it into my calorie allotment. I'm not in this to meet some specific goal on a specific date, this is the rest of my life. Parties, meals out, etc. happen and I just log them and move on.

As others here have pointed out, I wouldn't suggest it. A single cheat meal (within reasonable limits) may be beneficial, but an entire day doesn't seem too wise, especially since you seem doubtful regarding your self control.
If you're losing weight healthfully and slowly you shouldn't need to cut out everything you love or feel deprived, so if you're having urges to sit down with pint after pint of ice cream and order every carry out food item you can think of then I would suggest reevaluating your diet plan instead of succumbing to these urges.
For me personally at least, I began a very unhealthy restrictive/binge cycle which was very moderate and worked at first with my goals, but soon spiraled out of control and took a lot of effort and motivation to get back on track. Cheat days can easily get out of hand if you're not careful and leave you feeling ridden with guilt, hopeless, tired, and horribly bloated for several days. It's very easy for cheat days to cause disordered eating for most people, me being one of them.
But that all being said, different things work for different people, so do what you feel is best for you. Listen to your body, not your tongue - do you really need all those calories or do you just want/miss them?

If you feel you don't have the willpower to survive an entire cheat day and go back to your routine the next day - don't do it. Try a meal (really relish this meal), once a week and then go from there. I realized maintaining a healthy diet is all about your mental stamina. Once you realize how effortless it is to eat healthy, without thinking about cheating, you can try an entire cheat day! An entire day won't affect you if you follow your routine afterwards!

my wife and i usually have a cheat meal after we have accomplished a couple of weeks of dieting and exercise. We usually still log and try to keep it within our allotted calorie intake. We were out of town and we had a couple of cheat meals and i gained 9 lbs! No more cheat meals for me. I was 205 went up to 214. My next cheat meal will be when i am under 195 or for my wife's birthday (in a month), which ever is first.
my sister in law has a cheat day once a week and she has been able to lose weight and keep up with us. it all depends on your body and how bad the cheat meal/day is.
