IMHO, one can live on far fewer calories than is commonly assumed. The notion that one needs 2000+ calories a day sitting at a computer is absurd IMO.

I would agree with that. The MRE’s are 3000 calories. The military determined that is the right amount for a day of fighting.
I am estimating that a holed up person in a SHTF situation can get by on 6000-9000 calories per week. Thats two to three MRE’s. But its 23-34 servings of that Mountain House stuff. That’s a lot of food especially if you have to lug it around.
I just don’t think diet type food at 260 calories per serving is suitable for survival food. But, I do like the shelf life.
