Some science behind weight loss: 1. There has never been any safe and effective weight loss drug before Semaglutide. 2. Semaglutide was originally developed to treat Type 2 diabetes, but clinical trials found patients 'incidentally lost weight'—a surprising side effect. 3. Thanks to this drug, Novo Nordisk's market value is nearing $500 billion, making it the largest company in Europe, surpassing LVMH. Eli Lilly's market value has exceeded $600 billion, becoming the top pharmaceutical company globally. 4. If your BMI is less than 27, it’s not recommended to use it—the side effects outweigh the benefits. 5. Semaglutide’s weight loss effect is around 20-30%, similar to weight loss surgery. This info comes from a podcast by a nutrition doctor at Peking Union Medical College Hospital about weight loss.
