Adaptive TDEE

Adaptive TDEE is a Pro+ feature that re-fits your true total daily energy expenditure each week from the last 28 days of your weight trend and meal intake. If the fitted estimate diverges from your current calorie goal by more than ~100 kcal, Coach surfaces a banner on the dashboard proposing a new target — with a one-sentence rationale and a confidence rating.

The standard BMR / Mifflin-St Jeor math gets you close, but real-world TDEE drifts as you cut, bulk, recover from illness, gain or lose muscle, or change activity. Adaptive TDEE closes the loop by reading what actually happened to your weight against what you actually ate.

• Weekly cron, Sundays 10:05 UTC. Coach reads your last 28 days of weight logs + meal logs, fits the underlying TDEE, and proposes a new calorie goal.
• Confidence rating. The fit is tagged high, medium, or low depending on how much data was available + how consistent the trend was. Low-confidence fits are kept in your history but don't surface a banner.
• 200-kcal threshold. The banner only appears when the fitted target differs from your current goal by ≥200 kcal — small drift is normal noise.
• One-tap apply or dismiss. Apply updates your goal and writes an audit row to your TDEE history. Dismiss hides the fit for 7 days; another fit may surface next Sunday if the drift persists.

1. When the dashboard banner appears, read the proposed new target + the rationale. The rationale tells you whether the fit thinks you're eating more than you measured, less, or whether your weight trend has shifted.
2. If it matches your sense of the past month: tap Apply. Your calorie goal updates immediately; protein goal scales proportionally so the macro split stays similar.
3. If you suspect a confounder (sick week, travel, a heavy salt swing, female cycle phase shifting water weight): tap Dismiss. The fit gets shelved for 7 days. Coach won't re-surface the same fit; it might produce a fresh one next Sunday from a longer-window snapshot.
4. See your full fit history at /coach/tdee — every weekly fit + every apply/dismiss decision, with the chart of your calorie goal over time.

• Log weight most days. The trend-line math needs daily points to see signal through normal noise. A scale that auto-logs (Withings, Fitbit Aria, Renpho via Apple Health) is the easiest path.
• Log meals on the day they happen. Back-filling a week of meals three days late skews the fit toward the days you remembered.
• Stay reasonably consistent.The fit tolerates day-to-day variation but can't separate signal from a wedding weekend + a fast day on Monday + a 4-hour hike on Saturday. A typical week is the input Coach assumes.

Adaptive TDEE is on by default for Pro+ users. To stop the weekly cron from running (or to silence just the dashboard banner), open Profile → Goals and flip Adaptive TDEE off. Your history stays intact and you can flip it back on whenever.
