Above roughly 1% of body weight a week, the body starts spending muscle. Daily weight is mostly water and noise, so this tracks a rolling 28-day rate and tells you which side of the line you are on.
Log your weight once a week, same day, same conditions. We calculate your rolling rate as a percentage of body weight — and tell you the moment you break through 1% a week, which is where the loss starts coming out of muscle.
Morning, after the bathroom, before eating. Consistency matters more than precision.
Log two weigh-ins at least five days apart and your rolling rate appears here, along with an alert if you cross the cap.
Each bar is one weigh-in interval, expressed as % of body weight lost per week. The green band is the target zone.
Every entry, with the rate it produced.
