To determine how much weight has been lost, typically the starting weight is compared to the current weight. The difference between these two values is the total weight lost. For a more precise and motivating measurement, the weight loss can also be expressed as a percentage using this formula:
Weight loss percentage=Starting weight−Current weightStarting weight×100%\text{Weight loss percentage}=\frac{\text{Starting weight}-\text{Current weight}}{\text{Starting weight}}\times 100%Weight loss percentage=Starting weightStarting weight−Current weight×100%
If the starting and current weights are known, the exact amount of weight lost can be calculated in pounds or kilograms, and the percent loss can be computed for a more standardized measure of progress. If the user provides starting weight and current weight, I can calculate the exact weight loss and percentage. Otherwise, tracking tools or apps can help log daily or weekly weights to monitor progress effectively, such as using weekly averages rather than daily fluctuations to gauge true trends.
