I'm no expert but this sounds a little optimistic...

"The said a person could survive that long in the bush if they were able to conserve or use their energy wisely.
Yeah, they would [survive] but survival means not being dead so basically if you're not using up more calories than you've got then you can keep ticking on. So if somebody sat quietly and meditated and preserved what they've got in terms of energy and warmth they would be okay.
It's when they run around and expend more energy then they could go down quite quickly, so that's the crucial thing, in how you respond to the situation."

Surely you'd still need to make efforts to make shelter, gather water and forage or get food .
Then again , she did survive so she must have done something right .
