Four dose steps in, holding each one the full four weeks, and I am trying to work out whether the interval is a pharmacological requirement or a tolerability convention.
What would genuinely help is knowing what the trials actually did with participants who could not tolerate a step, because that is the situation I am in and the protocol summaries skip it.
Practical detail welcome, however dull — the duller the better.
Short answer first, then the reasoning. The trials generally allowed a step to be held or reduced and then retried, and people who did that mostly arrived at the same place a few weeks later. The end point of the ladder is set by tolerability, not by a schedule, and there is no evidence that reaching the top faster produces a better outcome.

Agreed on the arithmetic, with one condition: holding indefinitely at a dose that is not doing anything is not patience, it is a stall with a nice name. The distinction is whether appetite has changed at all at the current step.

Same position here, arrived at the long way round. Four weeks is the pharmacokinetics, not caution. With a one-week half-life you need four to five half-lives to reach steady state, so at two weeks you are dosing on top of a concentration that has not finished rising. Escalating then stacks exposure and you get the side-effect burden of the higher dose before you have seen the benefit of the current one.
Clinical perspective, offered as context rather than as advice.
Dose escalation anxiety for titration: I was terrified to move from 0.5mg to 1.0mg based on horror stories in this forum. But my actual experience? Slightly more appetite suppression, zero additional side effects.
Remember that the people posting about terrible side effects are a biased sample. Most people titrate up without drama — they just don't post about it because it's uneventful.
