One is "given the same calories, you'll be full longer." The other is "given fewer calories, you'll be full for as long." Surely those aren't orthogonal?

That seems like it'd be the definition of orthogonal; "length of fullness" and "caloric input" are separate variables, and each of those statements entails altering one of those variables independently from the other.

The definitions don't make reference to any particular food. And holding the food constant, presumably "length of fullness" and "caloric input" are strongly correlated, right? So if one of those statements is true, the other is very likely to be true. I would expect "orthogonal" to mean that there is no relationship between their truth values.

What am I missing?
