Understanding the average in pounds

The 14.9% trial average is applied here to three different starting weights. This figure is based on arithmetic and does not predict results for any one person.

What makes it stall, and what helps

  1. See where you stand in the dose steps. Each trial above found less weight loss at lower doses.
  2. Count how many doses you missed or took late in the past month.
  3. Note down a few days of what you eat and drink. As portions shrink, liquid calories and grazing build up.
  4. Discuss thyroid or blood sugar tests with your prescriber. If progress has stalled for months, also ask about changing medicines.
