Using GLP-1s drug injections for weight loss has become one of the latest ways some big names in the market are shedding extra pounds. Elon Musk recently tweeted about how using Novo Nordisk’s Wegovy helped him lose weight. Fanatics CEO Michael Rubin recently told CNBC’s “Squawk Box” that using a different version of Novo Nordisk’s same drug, Ozempic, which is most commonly associated with diabetes care, made him much less hungry.

“The weekly shot is amazing. … I started this about a year ago, it’s been life changing for me,” Rubin said.

Social media influencer Remi Bader said she was prescribed Ozempic after experiencing issues with insulin and weight gain.

GLP-1s — which stands for glucagon-like peptide-1 — are receptor agonists that work by imitating the effects of the GLP-1 hormone, activating GLP-1 receptors inside of the pancreas and producing more insulin inside the body. The insulin helps lower blood sugar levels, which can be helpful in managing Type 2 diabetes. GLP-1s also have been found to help with weight loss as they make individuals who use them feel fuller for a longer period of time.
