Weight Loss Drugs Ozempic, Mounjaro Likely To Impact Consumer Purchasing Behaviour: Nithin Kamath
According to a recent post on X by Zerodha co-founder Nithin Kamath, quoting FMCG giant Walmart, these drugs are already impacting purchasing behaviour.

Weight-loss drugs are trending, with Ozempic and the latest launch, Mounjaro—considered a likely equivalent to Ozempic—gaining popularity. But will these new drugs influence consumer buying patterns? The so-called 'miracle' drug, which has become popular among celebrities and the wealthy, has led to a global shortage.
According to a recent post on X by Zerodha co-founder Nithin Kamath, quoting FMCG giant Walmart, these drugs are already impacting purchasing behaviour. "It will have an across-the-board effect on every single industry," Kamath said.
"So far, not many people are taking them; even in the US, only about 6% of the people are taking these drugs," he shared on X. Kamath questioned whether these drugs will lead people to eat less, smoke less, buy less, and live longer. Last but not least, will they also trade less?

On March 20, Bloomberg reported that Eli Lilly is set to launch its first weight-loss drug, Mounjaro—the likely equivalent of the weight-loss drug Ozempic in India.
Kamath highlighted that right now we don't have a good understanding of the second-order effects of these weight loss drugs, but so far, even if half of what's being reported is true, then this will be the closest thing we have seen to a miracle drug.
