Great point, quite often people can be misled by "servings" per container. One should always look for calorie count to determine how long each container would last (i.e. 1 month supply).

I just looked at a Mountain House #10 can. It looks like a "serving" has about 250 calories, on average. I read somewhere on the forum that you can expect to burn around 2000 calories/day in an event. Does this mean that a #10 can could count as only one day's worth of food rations?
Take the caloric count per serving, multiply by the number of servings in the can.
If you have 8 servings in a can at 250 a serving, that's 2,000 calories. In most cases, that's not going to be enough.
How much do you burn on a normal day?
That depends on a multitude of factors. Initial size of the person being an important one.
The numbers below are based on a listed healthy BMI average, and average muscle build/bone density.
An active 6'4", male age 25, at 200# will burn 3,400 calories a day.
An active 5'8", male age 25, at 160# will burn 3,000 calories a day.
(Female numbers assuming non-pregnant non-lactating, they go up significantly if either case is true)
An active 6', female age 25 at 145# will burn 2,600 calories a day.
An active 5'4" female age 25 at 115# will burn 2,300 calories a day.
That last one is something many prepping families often fail to take into account. If the woman gets pregnant, or is nursing/lactating their calculations for caloric intake will be significantly skewed. If it's a long term SHTF scenario, they should either take that into account, or plan to abstain for the duration of the event. If they plan the latter, they had better have that idea sorted before hand rather than add the stress of that particular conversation during the event. In either case, it is fools folly to assume the wife/girlfriend would not get pregnant unless their is an established physical boundary such as having their tubes tied, or other medical condition that would preclude it.
Children are another special case. They are still growing, and as such, their caloric/nutritional intake will be increasing over time. The numbers need to be scaled up as the child gets older assuming a long term event.
Your specific frame build and bone density needs to be accounted for. This is where gender and ethnicity matter as well. All the above listed numbers are assuming an overall average. Your healthy weight and BMI must take into account these factors as well.

If BMD is included, then changing weight does not alter the fracture risk. However, in a meta-analysis about weight that was used to predict fracture,
it was shown that low body mass index increased the risk of fracture even after adjusting for the bone density.
Bone health is
almost universally lacking consideration in the prepping world outside of setting a fracture. With that is a near total lack of understanding for the connection between BMI and fracture risk. Added to that are the gender, ethnicity, and age considerations.
A broken pelvis, femur, or cracked skull could and likely would be a death sentence outside of modern medicine. Your BMI does matter when it comes to bone mass density, as does the consideration for dietary needs for a healthy BMD. That is especially important to women and more so aging women.
To summarize, there is considerably more to it than just 'calories', and a host of variables that must be considered.
, I was looking at geron's soup in a jar. I thought, why can't this be stored in mylar bags. Apparently, someone else on the blog (a different one) ask the same question and we were told it is just find and takes up less space. So my new quest is making my own "mre's". I've ordered my mylar bags and oxygen absorbers and am really looking forward to this. I've found additional recipies for this as well. They did memtion, you should have your food prepped and ready to fill the bags because you don't want the O2's out very long. In fact, if you have 2 ppl working together, it is even better!
