What does this video actually claim?
Madison Mulkey (@madisonmulkey) shares her three-week progress on semaglutide, showing visible abdominal changes and expressing satisfaction with her weight loss results so far.
The video doesn't make specific medical claims about semaglutide's effectiveness or safety. Instead, it's a personal progress update that shows physical changes after starting the medication. Mulkey uses hashtags linking semaglutide to Weight Watchers, suggesting she's combining the medication with a structured eating program.
This type of before-and-after content is common on social media, but it raises questions about what kind of results people can realistically expect from GLP-1 medications in the first month of treatment.
Is three weeks enough time to see meaningful results?
Yes, but the most dramatic changes shown in videos like this are often temporary and related to reduced bloating rather than fat loss. Semaglutide works by slowing gastric emptying and reducing appetite, which can lead to visible abdominal changes within days.
The STEP 1 trial (Wilding et al., NEJM, 2021) found that participants lost an average of 2.6% of their body weight by week 4 on semaglutide 2.4mg. For someone weighing 180 pounds, that's about 4.7 pounds. However, patients start on a much lower dose (0.25mg) and don't reach the full therapeutic dose until week 16 or later.
Much of the early visual change comes from reduced water retention and less food volume in the digestive system. The SUSTAIN-1 trial (Sorli et al., Diabetes Care, 2017) showed that gastrointestinal effects like reduced bloating occurred within the first two weeks of treatment.
What role does Weight Watchers play here?
Combining semaglutide with a structured eating program like Weight Watchers likely accelerates early results, but it makes it impossible to attribute changes to the medication alone.
Weight Watchers now offers semaglutide through their clinical program, but their points-based system can create additional caloric restriction beyond what the medication provides. This combination approach mirrors the clinical trials, which included lifestyle counseling.
The STEP 1 trial included monthly lifestyle intervention sessions along with semaglutide. Participants who received semaglutide plus lifestyle counseling lost 14.9% of body weight at 68 weeks, compared to 2.4% in the placebo group. However, teasing apart the individual contributions of medication versus behavior change remains difficult.
Should you expect similar results?
Maybe, but individual responses to semaglutide vary significantly, and social media posts tend to show the most dramatic outcomes rather than typical experiences.
The STEP trials showed that about 83.5% of participants lost at least 5% of their body weight, but response rates varied widely. Some people lost over 20% of their starting weight, while others saw minimal changes. Factors like starting BMI, insulin sensitivity, and adherence to lifestyle changes all influence outcomes.
Posts like Mulkey's represent individual experiences, not clinical evidence. The visual changes she shows could reflect anywhere from 2-8 pounds of weight loss, plus reduced bloating and improved posture for photos. That's within the expected range for early semaglutide treatment, but it's not guaranteed for everyone.
More concerning is that these posts rarely mention side effects, which affect up to 74% of people taking semaglutide according to the STEP trials.
