See whether your plan builds lasting speed. Compare actual loss, estimated deficit, and recovery quality. Turn weekly check-ins into smarter fat-loss adjustments without guesswork.
| Example metric | Sample value |
|---|---|
| Sex | Male |
| Age | 32 years |
| Height | 178 cm |
| Starting weight | 92.0 kg |
| Current weight | 86.5 kg |
| Target weight | 80.0 kg |
| Days tracked | 56 |
| Average daily calories | 2200 kcal |
| Estimated TDEE | 2850 kcal |
| Average steps | 9500 per day |
| Strength sessions | 4 per week |
| Cardio minutes | 150 per week |
| Sleep | 7.2 hours |
| Protein intake | 1.9 g/kg |
| Adherence | 88% |
| Waist change | 101 cm to 94 cm |
1) Actual weight loss
Actual loss = Starting weight − Current weight
2) Weekly loss rate
Weekly loss = Actual loss ÷ (Tracked days ÷ 7)
3) Weekly bodyweight change
Weekly change % = Weekly loss ÷ Average bodyweight × 100
4) Estimated daily deficit
Daily deficit = Estimated TDEE − Average daily calories
5) Theoretical fat loss
Theoretical fat loss = Daily deficit × Tracked days ÷ 7700
6) Waist score
Waist score normalizes waist reduction against tracked weeks. Faster useful shrinkage raises the score.
7) Momentum score
Momentum = 30% pace + 15% adherence + 10% steps + 10% strength + 10% sleep + 10% protein + 10% waist + 5% consistency
8) Lean retention score
Lean retention = 45% protein + 35% strength + 20% sleep
9) Plateau risk
Plateau risk increases when adherence, pace, activity, sleep, or deficit quality drop.
10) Four-week projection
The tool blends deficit-based expectation with actual pace, then adjusts for adherence quality.
It summarizes pace, adherence, activity, recovery, and waist change into one score. Higher values suggest your current fat-loss process is moving efficiently and consistently.
Actual loss reflects reality. Theoretical loss reflects the deficit model. Comparing both helps you spot water shifts, tracking errors, or maintenance estimates that need adjustment.
Yes, but interpret scale changes carefully. Waist, adherence, strength work, and trend pace may matter more than body weight alone during recomp periods.
Protein supports fullness and lean-mass retention during dieting. Higher protein usually improves recovery quality and makes aggressive cuts easier to sustain.
No. Extremely rapid loss can raise fatigue and muscle-loss risk. The score rewards a practical pace instead of pushing the fastest possible drop.
One week of gain does not always mean failure. Sodium, stress, digestion, and menstrual cycle shifts can mask fat loss temporarily.
Weekly updates work well for most people. Daily weigh-ins can still help, but weekly review usually gives clearer trend decisions.
No. It is an educational fitness tracker. Use a qualified clinician or dietitian for medical, hormonal, or eating-disorder concerns.
