Body composition

Body composition tracking: weight, body fat, lean mass, without the daily anxiety.

One bad scale day means nothing. Wellness Project smooths the noise, shows you the 7- and 28-day trend that actually matters, and lets your specialists see weight in the context of training, sleep, and food, not in a vacuum.

What's inside

Body comp the way it should be tracked

Smart-scale auto-sync

Fitbit, Withings, and Wyze sync through direct connections. Other scales can still flow through Apple Health or Health Connect when their companion apps write weight or body fat there.

Body fat and lean mass

BIA scale outputs import alongside weight. Body fat % and lean mass charted side-by-side with the weight line.

Trend-line vs daily

7-day and 28-day rolling averages overlaid on daily weigh-ins. The trend line is what we coach against, not the morning number.

Goal-aware deltas

In a cut? In a bulk? In maintenance? The dashboard shows your distance from goal and rate of change in lb/week.

Cross-domain context

Weight up 1.2 lb after a high-sodium dinner and 4 hours of sleep is not the same as weight up 1.2 lb on a normal day. Your specialists see both.

Manual entry in plain English

"Log weight 185.4." Done. No need to open the scale app.

In the app

One number is noise. The trend is the signal.

Daily scale weight bounces ±2-3 lb on water, sodium, glycogen, and sleep alone. Most apps show you the daily number and let you panic on it. Wellness Project leads with the 7-day rolling trend; the daily reading is there if you want to see it, but it doesn’t drive the conversation.

For a recomposition (gaining lean mass while losing fat), we plot body fat % and lean mass on the same chart with two y-axes. Lean mass up while body fat trends down is the recomp picture; if it’s not happening, Casey and Rex talk about why.

Smart-scale BIA is imperfect but consistent. Wellness Project doesn’t pretend a 0.5% body-fat change overnight is real; we look at 4-week deltas and call out the meaningful ones.

See Noom alternatives: free, data-grounded weight coaching for the tradeoffs side by side.

Read Macros for body recomposition: how to eat to lose fat and build muscle for the underlying concept and how to use it.

FAQ

FAQ

Does it support DEXA scans?+
Yes. Log a DEXA-derived body fat % or lean mass like any other body metric, and it plots alongside your daily BIA readings.
How often should I weigh in?+
Daily, same time, post-bathroom, pre-coffee, that gives the cleanest signal. We average over 7 days so any single miss is fine.
