As new diabetes and weight-loss drugs help patients curb appetites and shed pounds, food manufacturers are looking for new ways to keep their bottom lines plump.

Millions of Americans have begun taking the pricey new drugs—particularly Mounjaro, Ozempic, Wegovy, and Zepbound—and millions more are expected to go on them in the coming years. As such, food makers are bracing for slimmer sales. In a report earlier this month, Morgan Stanley's tobacco and packaged food analyst Pamela Kaufman said the drugs are expected to affect both the amounts and the types of food people eat, taking a bite out of the food and drink industry's profits.

"In Morgan Stanley Research surveys, people taking weight-loss drugs were found to eat less food in general, while half slashed their consumption of sugary drinks, alcohol, confections and salty snacks, and nearly a quarter stopped drinking alcohol completely," Kaufman said. Restaurants that sell unhealthy foods, particularly chains, may face long-term business risks, the report noted. Around 75 percent of survey respondents taking weight-loss drugs said they had cut back on going to pizza and fast food restaurants.
