Movie-theater popcorn is a calorie and fat disaster! Most theaters pop their kernels in exorbitant quantities of coconut oil, which is more than 90 percent saturated fat (that's the type of fat you should be trying to dramatically limit in your diet). Worse yet, portions are absolutely out of control! A medium size can be piled high with up to 20 cups of greasy popcorn, which will cost you 1,200 calories and 60 grams of saturated fat before you even factor in the buttery topping they automatically squirt on top of your tub. That's the caloric equivalent of three large fast-food burgers — and the saturated fat equivalent of a full stick of butter! Ordering popcorn at theaters is a habit you definitely want to break. Instead, get your fix when you're having movie night at home, and enjoy low-cal air-popped or light microwave popcorn for just 30 cals per cup.
