Drug Trials

The trials for semaglutide, known as the Step trials, are extensive and structured like moon missions, with each step focusing on different aspects of the drug's effects. Michael Hobbes explains that these trials involve over 5,000 participants globally and are funded by Novo Nordisk 1. The results are promising, with 80% of participants losing weight, and a third losing more than 20% of their body weight, comparable to bariatric surgery 1. Aubrey Gordon notes the trials' diversity issues, as most participants are white, which is common in diet studies 1.

   

Side Effects

Semaglutide's side effects are nearly universal, with many experiencing gastrointestinal issues like nausea and diarrhea. Michael mentions rare but severe side effects, such as pancreatitis and potential thyroid cancer, though these are based on rodent studies 2. Despite these side effects, dropout rates in trials are low, indicating that participants are willing to endure them for the drug's benefits 2. Aubrey highlights the gap between popular claims and actual research, noting that weight regain is common once the drug is stopped 3.

   

Real-World Use

In real-world applications, semaglutide's effectiveness is less pronounced than in trials, with average weight loss around 7.5% compared to 15% in controlled settings. Michael attributes this to the lack of dietary counseling and support in real-world scenarios, which are present in trials 4. Adherence rates are also lower outside of trials, with significant dropout rates 4. Aubrey points out that weight regain is a significant issue, as people often regain weight once they stop taking the drug, similar to fad diets 3.

   

Shortage Issues

The shortage of semaglutide has led to a rise in compounding pharmacies creating unregulated versions of the drug. Aubrey explains that these versions may not contain the active ingredient, as Novo Nordisk holds the patent until 2032 5. This shortage impacts both those seeking weight loss and diabetes management, as doctors prescribe Ozempic off-label, exacerbating the issue 5. Michael criticizes the lack of regulation, comparing it to buying unverified products online 6.
