At basecamp we eat like we would at home. For breakfast we have eggs, pancakes, hot cereal, coffee, tea, milk. Lunches can be sandwiches, soup, dried fruit, vegetables, nuts. Dinners are usually soup, rice, potatoes or pasta, some sort of meat or lentils, and dessert. Once we begin climbing and have to carry everything up the mountain on our backs, weight becomes crucial, so we usually eat high calorie light weight foods. Breakfasts are hot chocolate, hot cereal, lots of sugar and butter. Some climbers will eat butter cubes straight, like a popsicle. Not me. My favorite breakfast was a cup of freeze dried potatoes with half a cube of butter. Other climbers don’t even drain the grease off their bacon. They eat it. Lunches are usually taken in the form of snacking all day on dried fruit, candy bars, power bars, nuts, canned fish, cheese, dense breads. Dinners are typically soup, freeze dried dinner, hot drinks. The most important thing on a mountain is to stay hydrated. We must drink an incredible amount of liquid. Between 7-9 quarts of water a day. If you become dehydrated you become weak and tired. When you hydrate you stay strong and healthy. I usually drank a lot of my calories with a high carbohydrate/high calorie drink mix. 1000 calories per quart of water. Many climbers lose weight on climbs, not me. I either stay the same or even gain weight. But it takes training to make yourself eat and drink at high altitude, because you tend you lose your appetite the higher you go.
