GLP-1 & Weight Loss

Patients considering semaglutide often search for before-and-after photos to understand what results they can expect. While individual outcomes vary, clinical data and our experience at Rani Beauty Clinic in Renton, WA, allow us to outline a realistic month-by-month timeline of what most patients experience.

During the first month, patients typically lose two to four pounds as the body adjusts to the lowest starting dose. Appetite reduction is usually noticeable within the first one to two weeks, though nausea and mild GI symptoms are most common during this period. By months two and three, as the dose is gradually increased, weight loss accelerates. Most patients lose an additional four to eight pounds during this window and begin noticing changes in how their clothes fit and how their face looks.

Months four through six represent the peak weight-loss phase for many patients. The medication has reached or is approaching its full therapeutic dose, and the combination of reduced appetite, improved food choices, and increased activity often produces the most dramatic visible changes. Patients typically report losing one to two pounds per week during this period. By the six-month mark, many patients have lost 10 to 15 percent of their starting body weight.

From months six through twelve and beyond, weight loss continues but may slow as the body approaches a new set point. Total weight loss of 15 to 17 percent is consistent with clinical trial averages. At Rani Beauty Clinic, Dr. Landfield monitors body composition, not just scale weight, because patients who exercise and eat adequate protein often build lean muscle while losing fat, which can make scale-based progress appear slower than it actually is. The most important before-and-after comparison is not just weight but overall health markers including blood pressure, blood sugar, cholesterol, and energy levels.
