What it is

Body-weight trend tracks weight change over time rather than one measurement.[1,2,3]

Why it matters

Weight trend can connect energy balance, fluid retention or loss, thyroid context, nutrition, illness, medication effects, and body-composition changes.[1,2,3]

What it affects

  • It is a trajectory variable, so direction and timing matter.[1,2,3]
  • It can be downstream of many upstream systems.[1,2,3]

Interpretation traps

  • Scale, timing, clothing, hydration, and measurement frequency affect the signal.[1,2,3]
  • BioConst does not interpret weight changes or give weight-management advice.[1,2,3]
