Maybe you don’t want to know. The Center for Science in the Public Interest has just released the shocking truth about the calories and fat grams you’ll find in a menu’s worth of popular restaurant dishes.

An offer at one of the country’s leading burger joints, which has 550 locations in 35 states: a bacon cheeseburger and large fries combo that weighs in at a whopping 2,380 calories. That’s more than many people should eat in an entire day.

At another eatery is a popular chocolate truffle cake that delivers 1,670 calories and more than two days worth of saturated fat. And that’s just for dessert.

Chinese anyone? According to CSPI, a popular double pan-fried noodles combo at one of the nation’s most popular Chinese chains packs 1,820 calories. The salt it contains is even more outrageous—the equivalent of three teaspoons, the equivalent of five days recommended adult intake of sodium.
