You can’t say they’re not healthy eaters, if she went up the mountain with a McDonald’s take away you’d all be complaining she died of a heart attack
Being real...McDonalds wouldn't be my choice most of the time, 'cos it might give me indigestion, but it would fuel you quite well on a hike. I'd skip the French fries, though. And a snack a couple of hours later—maybe peanut butter on dried apple—would be a healthy follow up.
By way of example, while ultra-distance hiking I showed up once at a Hardees/Carls Junior and ordered the biggest hamburger they had. The gal behind the counter said, "Are you
sure? That's REALLY BIG." I said, "Yep, totally." I scarfed it in about 2 minutes and considered ordering another.... But sometimes you can have too much of a good thing to be comfortable "making miles". Heart attacks be blowed, though: I never even thought of that.
Take out a piece of pumpkin pie for later. Back on the trail.
By dinner, I'd want 2 full servings of my whole "Thanksgiving dinner".
I've still only mentioned 2/3 of the calories I ate that day. So, yep, no problem with the McDonalds (the guys could eat, like, 5 of those at a sitting).
Because ED's body had already been primed by an extensive summer hike, it would have been close to this kind of food-crazed mode. And an organism like that needs a LOT of food to function, way more than you'd eat at home. This might well be why she had "cravings." It's possible she misidentified them as "lack of control", when the food was absolutely necessary for what she was doing.
