Japanese snacks.
They resemble thin long pretzle sticks, and they appear to have been dipped in yogurt. There's regular sized Pocky, and then there's jumbo Pocky.
I don't know if you've seen those ads for the 100 calorie packs of "Oreos," but they are absolute crap. "The food is bad, and the portions are small," my parents would say.
In contrast, Pocky is delicious. There are millions of flavors, including chocolate, vanilla, strawberry and "men's", which supposedly has hormones in it.
I like strawberry the best. The reason why I compare Pocky to Oreo snacks is because you buy this box of Pocky and there is so much of it. And it's one serving, and it's 200 calories. So I have to say, that's why the Japanese are thin.
They even sell this stuff in the US. I've found it in the "internation foods" section of Cub. Check it out.
