Recently, nutritional drinks that fulfil the complete nutritional requirements of adults (optimum proportion of carbohydrates, proteins, fats and other nutritients) have been on the rise. Backpackers are probably not the target audience, but their needs should be served pretty well by these shakes.

Popular brands are Soylent (US only) or Joylent (Europe based but shipping worldwide).

Personally, I have tried Joylent and I still drink it from time to time, especially if I need some quick energy after work before going to the gym but don't have the time to cook. It's not a culinary explosion, but I think it wouldn't be a big problem to live off it for two weeks, especially if you add dried fruit for some variety.

It's about 2100 kcal per bag of 600 grams, so for 10 days, assuming you need more than these 2100 kcal due to the permanent exercise, you'd end up with around 10kg. That's quite a load, but significantly less weight would only be possible with a far more fat-centered diet. Apart from the powder itself, you only need water and a plastic shaker. No fire necessary. As long as you have access to fresh water, using the same shaker all the time shouldn't be a problem (if you clean it properly).

Realistically, I wouldn't live off that stuff alone, but for my next longer trip I'm planning to cover about half of the food needs with Joylent.

Brands that I've personally tasted are Jimmy Joy (formerly Joylent) or Huel, YFood and Saturo.

They also come pre-mixed with water, but that's of course way heavier and also more expensive.
