Make sure not to eat any food the day of the climb
That's the first time I've ever heard anyone recommend that! Based on the recommendations in
this book, as well as members of this forum, I try to consume 2-3k calories on a Whitney dayhike.
And most importantly, to me, chowing down a few kazillion calories in the 24-36 hours prior to the hike in the form of complex carbs that will still be with you on summit day. Pasta is my personal choice. My appetite always goes on strike above 12K', so I really load up beforehand. My last two times up Whitney my trail food was mostly one of Doug's monster pancakes broken up in baggies and GU Chomps. And, of course, Snickers . . .
