No. A future weight, target date or weekly pace shown on a result page is an estimate, not a promise of what your body will do. Your actual progress depends on your starting point, overall intake, activity, health and how the routine works for you.
An example such as 145 lb by a particular date or 2 lb per week should not become a deadline you try to meet by skipping food. Weight can change unevenly, and a quiz cannot predict every factor that affects it.
Use the result to understand the proposed routine. Follow progress over time and ask for a review if the target feels unrealistic or the plan leaves you regularly hungry or unwell.
