Uh, two things:
a. It is quite possible to eat at any of those places and lose weight. It's all in choices. Not one of those places is holding a gun to your head and making you purchase fattening things. Even at Kings Island, half way decent healthy choices can be found, though it is way too hard to do so. Why, for instance, can I not buy a banana in the park? An apple? Some grapes? An orange?
b. Not all of us are fat. Some of us used to be, and after a long, dedicated effort, no longer are. Others are not YET fat...still others never will be. Like most generalizations, saying restaurants are trying to make us all fatTER is an unfair generalization, Some people, God bless them, can seemingly eat anything without gaining an ounce. And some of them want badly to gain, and can't.
Terpy, just sayin' (and who was thrilled when, about ten days ago, in the strangest of settings, was referred to as "that little man on that table over there." I was so happy I almost forgot entirely where I was and why!
you also forgot to mention the ones like me who do watch what they eat, can just simply look at a peice of food a gain weight it is all in the metabolism and genetic make-up that depends wether the are skinny and stay skinny or the fat shall stay fat even though they may appear to lose weight at first it comes back ten fold im livin proof tried dieting 3x and resalts as just stated comes back tenfold we can debate about that all day and never meet middle ground so lets drop it and move on shall we
