Probably the best aspect of the Alone tv series is communicating this wisdom. The folks who make it past 50 days are in lipolysis and breaking down fat to survive and they minimize actions and huddle in their sleeping bag as just going out to get dandelions would end their energy reserves and that would send them home.

This week, a guy who took a moose is coasting because he has an ABUNDANCE of meet but a critter, likely a wolverine, took the moose fat. That was a gallon of fat estimated at 35,000 calories or say 13 days worth of energy.

There is no way to get that back and no wild edibles that could replace this other than another moose.

There are no plant sources like that even walnuts or pecans. And that would take lots of work to process. Even if he had acorns, the tannin removal would take a lot of work calories.

This is why you need meat and fat to survive.
