For months, chatter has surrounded Eli Lilly’s three-hormone medication retatrutide, touted for its extraordinary potential to drive weight loss. The just-released Phase 3 findings from the company more than justify that buzz. The manufacturer states that participants receiving 12 mg of retatrutide shed, on average, 70.3 pounds (28.3%) over 80 weeks, and 45.3% of participants achieved at least 30% weight loss—a threshold traditionally associated with bariatric surgery.
Retatrutide stands as the latest entrant in the wave of hormone-based therapies that began with the advent of semaglutides such as Ozempic in 2018 to treat Type 2 diabetes. Marketed as Wegovy, this compound gained approval for weight management in June 2021.
Perhaps it is purely coincidental, but adult obesity reached its peak around roughly the same period.
Apart from helping people manage diabetes and shed substantial fat, these compounds appear to offer a wide range of additional health benefits. They seem to improve outcomes for individuals with cardiovascular, kidney, and liver conditions, arthritis, sleep apnea, and substance-use disorders, while generally reducing inflammation. Newer data hint at a meaningful lowering of overall cancer risk and a reduced likelihood of cancer spread. Recent research also helps ease concerns that fat loss might be accompanied by a loss of muscle mass.
Health and Human Services Secretary Robert F. Kennedy Jr. initially criticized the compounds for treating diabetes and obesity, urging Americans to improve their diets instead. He claimed that drug companies are “counting on selling it to Americans because we’re so stupid and so addicted to drugs.” However, when President Donald Trump endorsed the therapies, the secretary deftly reversed course.
The adoption of these compounds by Americans already appears to be reshaping parts of the economy. Specifically, demand for higher-protein foods has risen, while demand for alcoholic beverages has declined. In a curious turn, the drugs seem to nudge people toward healthier eating habits just as RFK Jr. has urged.
