According to an MSNBC article:
Well, I, for one, don’t always have room for desert. In fact, I pretty much never do. After stuffing my belly with hot food to the bursting point, the thought of any kind of food, desserts included, turns my stomach.
I do enjoy dessert foods, but the only time I eat them is between meals. Am I a freak? Do you guys always have room for one more bowl of ice cream?
I could be completely stuffed and still have room for ice cream or cake.
Nope. I don’t always have room for dessert.
Yes. Especially if it’s ice cream. You just open up the old hollow leg and chomp away.
I hardly ever have room for desert. Much to my regret, at times.
I have a habit of checking the Dessert Menu List, and if there is something realing good, I will not finish my dinner, I may eat only half of it and take home, to have room for Dessert.
At the buffet, instead of going back for dessert, I go back for …
another piece of fried chicken. Yum.
But no, I don’t always have room for dessert. As a matter of fact, I rarely eat sweets.
Is it fair to say “it varies”? I don’t always have a dessert. I order what main meal I want and try to leave room for a reasonable dessert, but I finish the meal and then decide. As a rule, the dessert is heavy: ice cream, pie a la mode, or some pastry confection, occasionally sherbet or sorbet.
At home I make sure I have room for dessert by eating it first. Sometimes that’s the meal! 
I very rarely have room (or desire) for dessert. I’d rather fill up on dinner! I just prefer salt to sugar.
I do indeed always have room for dessert. Even when I honestly feel full, completely stuffed, when it comes to non-sweet food. It’s like it’s a completely different stomach or something…
Sadly, at this age, I do not always have room for dessert. At a certain point, you cannot belong to the clean plate club. At least I can’t.
Like, Intaglio, I order and eat according to whether or not I’m interested in dessert.
Not to hijack, but intaglio, do you work for the Treasury, or what? What a cool name!
Depends on how I feel after the main course. Also depends on the dessert menu, and how much $ I have in my wallet.
Interestingly enough, when I was actively overweight (not trying to do anything about it, in other words), I did always have room for dessert. Now that I’m physically fit and have lost a significant amount of weight, I’ve apparently retrained myself, and I rarely have room for dessert if I haven’t consciously eaten less than I wanted of the main course.
Very rarely, if I want dessert, I have to have it by itself. Plus, I’ve noticed that the more ancient I get? The fewer sweet things appeal to me.
I’ve even started being turned off by GASP my usual favorite “death by chocolate” type ice cream!!!
I leave room for dessert, and even after I have it there’s still room for more. I’ve really trained myself (since losing about 60 lbs.) to eat until I’m satisfied instead of eating until I can’t comfortably have another helping of something that was particularly good or have that ice cream bar or slice of pie. Mm, pie.
This was a subject discussed widely when I attended culinary school. Seems that taste buds will burn out after a few bites of the same food (you can still eat it, of course, but it’s not as interesting as those first few bites). That’s why having a meal of several courses can be far more satisfying than one HUGE plate of just one thing. And this, of course, explains this particular phenomenon of being able to eat dessert while full otherwise.
Now, that being said, it really depends on what kind of meal I’ve had on whether or not I’ll have dessert. Often enough, I usually go for it, especially if I’m at a new restaurant. I always have to check out the other guy’s desserts.
I seem to have lost my sweet tooth somewhere along the way. I usually am more interested in the meal than dessert although some folks I know seem to endure the meal so they can get to the dessert.
Actually, I hate most desert type foods, so I never “save” room, and I never have room when they bring the desert.
Chocolate brownies are the exception, I can be full and still eat a good chocolate brownie or two.
Even if I’ve had a 19 course meal I will always have room for dessert! Especially if it’s chocolate bread pudding or creme brulee. As Melandry has already stated, I honestly do think there is a separate chamber/stomach where all the dessert goes!
