Depends what sort of weight you are intending to carry to carry that depends on where you are intending to go and for how long

If you take an msr wisperlite, you probably are not planning on any serious ascents, notbothered about your pan(s) weight, not frugal on the fuel. Your bag can be heavier, sleeping bag warmer etc.

Truthfully if you are trying to go lightweight give up the cooker, 50g cooker 100g pan, 200g fuel, the bother of the food you take, if theres water in it weight increaces drastically for energy content, or the extra water you have to toat anyway for freeze dried food, this easily adds weight. Block of cheese, snickers bars salami etc seem a lot lighter, exept for the salt makes you more thirsty.
