Weight is altitude.
The summit is your goal weight and the trailhead is where you started. Each morning's weigh-in feeds your 7-day average, and your climber moves to match it. One salty dinner doesn't send you back down the mountain.

Set down a stone at every flag.
Your climber carries a pack of stones. At each flag one comes out and is built into a cairn, and the pack gets lighter. Only the pack changes. Your climber's body never does.

A guide for every plateau.
When your average stalls, the Waylighter comes down from the mist. He asks a few plain questions and gives you one next step. He never suggests fasting, skipping meals or supplements.
“Steady days. That is the whole secret.”
