A plateau can feel like the plot stalled. Often it is the body consolidating, adjusting water, or waiting on sleep and stress to catch up.
Before rewriting the plan in a panic, ask what else moved. Energy. Appetite. Consistency. A short week of illness. A long week of travel.
If a plateau lasts and bothers you, bring it to a clinician — especially if medicine, metabolic health, or other conditions are part of your picture. On this site, a plateau is a chapter, not a sentence.
