What changes the estimate
A smaller weekly pace produces a longer timeline; a larger pace produces a shorter one. The tool does not know whether the selected pace is appropriate for every person or situation.

A timeline is a range, not a promise
The result divides the distance between current and goal weight by the pace you selected. It is useful for planning, but water shifts, adherence, training, sleep, stress, medication, and health context can all change the path.
Review the timeline as your trend changes
Use a trend rather than a single daily measurement. Revisit the estimate when the goal, rate of change, activity, or professional advice changes.
Method used
Uses the difference between current and goal weight with conservative weekly change ranges. It does not guarantee outcomes.
The estimate should be compared with real-world outcomes over time. Body weight trends, training performance, hunger, schedule, sleep, injury status, and consistency can all change what works in practice.
Important safety note
This tool is for general fitness education and planning context. It is not medical advice. If you are pregnant, managing a medical condition, recovering from an injury, changing medication, or unsure whether a calorie or training change is appropriate, speak with a qualified clinician.
