o sure it's just fine if you have the calories to spare..
let's not forget tho people that dieting means eating in caloric defacit. Look at it this way, if you find your base maintenance cals to be 2000 and you've eaten 1900 cals that day, and have done no exercise to put yourself into a great caloric defacit that day (meaning you really didn't do much towards your cutting goals that day..) then yeah, guess what, the pretzles gonna screw you. You're not going to be under maintenance anymore.
however f your maintenance is 2000 and youre dieting like a madman anddoing cardio and you've already put yourself 500 or so cals in defacit that day or whatever then sure you've got the room to spare to eat the stupid stinking pretzel. Go for it. Give in to yourself. Let the pretzel win. Or you can BE STRONG and just wait till your cheat day.
Come on think about it, 100 cals closer to losing another lb. of fat, or the 5 second taste of a pretel. You gonna give in?
I'm a firm believer that one of the "wonders" of dieting is also about making yourself do things you do not want to do and overcoming urges. It's a lesson in self control, which I believe everyone probbly needs to work on more.
