Climbing meal planning tools?

Does anyone have good tools (spreadsheets, rules of thumb, etc.?) for meal planning over for extended climbing expeditions? On a big day or weekend trip being a little light or heavy on food isn’t a big deal. But over a long trip it could mean carrying several extra pounds vs being a few days short on food. I’m sure guide services have this pretty dialed in. TNFA has a great section on nutrition but I’m having a tough time extrapolating it onto a ‘macro’ level.

I remember reading a blog from an Alaskan adventure racer that said with careful planning he would budget 3,500 cals in 2 lb (1kg) of food per person per day. I used that as a guideline for planning a Denali trip a few years ago and found we really brought too much food. I’d say that over the course of 1-3 week trips into the mountains, on average one-third are big strenuous days (fueled by Gu, drink mixes, etc.), one third are rest/weather days, and one-third are moderate exertion days like approaching, moving camp, shorter climbing days, etc.
