The numbers that improved before the scale did

For the first month the scale barely moved, and I nearly stopped on the strength of that. Other things had already changed; I simply was not measuring them, so they did not count.

What moved first

• Resting heart rate. Down by several beats a minute within about three weeks of walking daily. This is the one I wish I had tracked from day one.
• The stairs. Four flights to my flat. In week one they were an event; by week five they were just stairs. Nothing on the scale reflected that.
• Sleep. Falling asleep faster, and waking up fewer times. Hard to quantify honestly, impossible to miss.
• Blood pressure. Mine was mildly high at the start and came down over a couple of months. That one I checked with a doctor rather than deciding for myself what it meant.

Why this matters for staying with it

Weight is a lagging indicator, and it is noisy on top of being slow. If it is the only thing you measure, then for the first several weeks your evidence is thin and mostly discouraging - which is exactly when people quit.

Two extra numbers, taken once a week, changed how the early period felt. They were moving while the weight was not, and they were moving for the same reasons.

One caveat worth stating plainly: I am describing what happened to me, not giving medical advice. If your blood pressure is high, or something is not moving the way you expect, that is a conversation for a doctor and not for a blog.
