Why am I losing weight slower than the clinical trial averages?

Individual weight loss varies significantly from clinical trial averages due to multiple factors. Your starting BMI, age, sex, metabolic rate, medication adherence, and concurrent health conditions all influence results. Clinical trial participants receive intensive dietary counseling, regular monitoring, and have strict inclusion criteria that may not reflect real-world diversity. Some people are 'slow responders' who lose weight gradually but consistently over time. Others may need dose optimization or have underlying conditions affecting metabolism. Hypothyroidism, polycystic ovary syndrome, and certain medications can slow weight loss. Focus on your personal trend rather than comparing to averages - losing 0.5-2 pounds per week consistently is healthy and sustainable.
