Thanks Pika, that's a very good answer.

I remember this from some survival training. the choice was to live in the woods and fatten up on trout, or make for the coast and find people.

It turned out you'd have to eat about 3-4 POUNDS of trout before you could expect to "fatten up" at all. Best to head straight out.

And that's something those idiots on the Man Vs. Wild ought to know. They consistently spend hours of time and energy trying to get food that has no nutritional value. It's bad advice, all the way round.
