Yes, it starvation. Yes, it's not particularly pleasant or healthy. Yes it's temporary. Yes it works if you can stick w/ it.
Do you really think a PSMF is compatible with a heavy endurance training routine? This goes back to the question of whether a ketogenic energy cycle is adequate energy for long-term efforts, but at the very least she'd have a couple of weeks of adjustment before she could properly use the ketone bodies, and her training would suffer just when she needs that least.
