Do not judge your weight progress based on a single weigh-in or a short period; instead, use weekly averages or trend tracking applications to neutralize natural variations in water retention.

The community is converging toward a solid consensus: daily weight is volatile and does not always reflect actual fat loss. Research broadly confirms this phenomenon: water fluctuations due to salt, hormones, glycogen stores, or physical activity are physiologically normal and independent of caloric balance (observational studies on water mass variations). The use of moving averages, as suggested, is a validated approach to smoothing out this statistical 'noise.' However, members rightly point out that after 4 weeks without a downward trend, the probability of an error in caloric estimation becomes statistically predominant, which aligns with the principles of thermodynamics. It is no exaggeration to say that isolated weigh-ins are misleading, but one must keep in mind that rigorous tracking remains the foundation of a deficit. This advice is therefore a proven field practice, although daily tracking may be psychologically difficult for some.
