The Movie Theatre - A Dieters Garden of Eden!

How many of us have been minding our diet and watching what we eat until cinema night? For the rest of the week, we do our best to avoid the pitfalls of bad eating habits and practising good nutrition ones, yet that night we have no problem chugging down a vat of coke, inhaling a trough of popcorn accompanied by a Ben & Jerry's chaser! It's come to the stage that although I'm always looking forward to the forthcoming movie, the thoughts of the punishment I'm going to put my digestive system through fills me with dread.
But why is this so? Why do we have to fill our guts with enough junk to fatten a small piglet and are there any alternatives to this over consumption?
Firstly, the environment of a movie theater doesn't help our cause. The aroma of freshly (or not so freshly) popped popcorn, the fact that everyone around you look like they require a sherpa to help them carry the amount of grub they have and the nice darkened room where nobody can see your shame as you wolf down the lot before the trailers are over just enables this binging behavour!
Then, I wonder, if am I alone in these guilty emotions of over consumption and if other moviegoers  feel the same and if so what do they do to counter act this cinema self sabotage.
On researching (and by that I mean "googling")  healthy cinema snacks, two factors immediately jumped out at me.
1. A lot of movie goers do indeed eat healthy, however, that brings me on to...
2. The amount of contraband smuggled mirrors something out of Scarface and sees a lot of us channelling our inner Howard Marks to overcome our avoidance of high calorie treats!
It seems to me that an alternative healthy option needs to be established to cater for the "wanna-be-healthy" movie goer but I can't see the big omniplexes going for it somehow as the mark up on the "good stuff" is huge (but that's a whole other story!)
I have therefore reached the conclusion that it appears that our consumption choices are boiled down to:
(a) starving yourself (or eating beforehand but that doesn't sound half as dramatic as "starving yourself"!)
(b) continuing down the road to obesity (but what an enjoyable road it is!) or finally,
(c) loading the "ryanair jacket" with lots of fresh fruit and nuts and munch away safe in the knowledge that your digestive system thanks you but constantly looking over your shoulder at every turn in case you're hoisted by the usher for crimes against cinema!

Any other suggestions would be most welcome!
