Tool snapshot
Fat mass trend can be more useful than scale weight alone.
Example result
Weight x body fat
This is a sample only. Use your own stats and compare the result with your weekly trend.
Start with your current body stats and activity level, then compare the result with a realistic weekly pace. For most weight-loss goals, the number is not meant to be perfect on day one. It is a starting point that becomes more useful after you compare it with two weeks of weight trend data.
The key result for this page is Weight x body fat. Use it with the live planner to connect the estimate to calories, meals, steps, and a goal date.
Do not cut calories aggressively just because the math says faster is possible. Extreme targets are harder to follow and can reduce training quality, mood, and consistency.
If your 7-day average is not moving after two full weeks, adjust by 100-150 calories or add a small amount of daily walking.
Track calories, protein, steps, waist measurement, and scale trend. One weigh-in is noisy; the trend is the signal.
