The first few days of a long hike, my appetite and my wife's are suppressed. We live mainly on trail mix that we consume during the day. And chocolate covered coffee beans in the late afternoon, when we need a stimulant. The appetite starts to come back around day six. Normally I've lost about two kg by then, after allowing for trail dehydration. After two weeks or so, I'm down about 4 kg.
