Exercise transformation with training: went from barely able to walk a block to completing a half marathon last Saturday.

This answered a question I did not know how to ask. Taking it to my next appointment.

From the other side of the consultation, briefly. The useful move here is to separate what is established from what is widely repeated. Those two sets overlap less than the confident tone of most write-ups suggests, and the second set is where nearly all the disagreement on this board comes from.

The mechanism and the magnitude are separate questions.

Pushing back on newstart_MO here. This treats a plausible mechanism as a demonstrated one. Plausible is where you start looking, not where you stop.

Adding the numbers, since they settle part of this. Keep the original post as written when you update it, and add the correction underneath. An edited-away mistake is invisible to the next person who makes it.

Moderator note: a post naming a supplier has been edited. Discuss suppliers in the review sections, not here. Report rather than reply if it drifts again.
