the short answer
When a compliant client is not seeing results, the answer is almost always in the data, not the plan. Before you change anything, check four things from what they have already tracked: the weight trend over weeks rather than days, whether logged intake matches actual, whether you are watching the right metric for the goal, and whether the timeline is realistic. Most "no results" is under-reporting, measurement noise, the wrong number, or an unrealistic clock - not a broken program. Diagnose from the data first, then change one variable and read the trend before you change another.
