What kind of food should I expect on a trek?

Lunch and dinner almost always start with soup because it’s cold in the mountains and you need to hydrate. Meals are relatively light with small portions because digestive systems don’t work as well when you’re at altitude, i.e. when your body is functioning with less oxygen than it’s used to. However, trekking agencies cook plenty of food, so there’s always seconds and thirds if the portions are too small for you.
