Both come from a bioimpedance scale, which estimates them by passing a small current through the body. The estimate shifts with hydration, food and time of day, so a single reading is unreliable. Weigh under the same conditions and read the trend over weeks.
Body mass index is weight divided by height squared. It takes no account of muscle, so it misclassifies many trained athletes as overweight. It is included for completeness and is the least useful number on this screen for anyone who trains.
The energy your body uses at complete rest, estimated from your height, weight, age and sex. It is a formula, not a measurement, and individuals vary substantially around it.
The energy attributed to movement and training, on top of your resting requirement. Devices estimate this from heart rate and motion, and the error is meaningful - treat it as a relative signal between days rather than an exact figure.
Energy taken in minus energy spent. Both sides are estimates, so the balance carries the error of both. A persistent large deficit alongside hard training is worth attention: under-fuelling degrades recovery, sleep and adaptation before it shows up on the scale.
A projection from your recent energy balance, not a measurement. It assumes the estimates on both sides are accurate and that nothing else changes. Treat it as a rough direction, and let the actual scale trend settle the question.
Minutes of moderate or vigorous activity, with vigorous minutes counted double. It follows public-health activity guidance rather than a training metric, so it answers 'am I active enough' rather than 'am I training well'.
