Signal 75% of Gen Z and 73% of millennials use health-tracking tools against 32% of boomers

Summary

McKinsey reports that consumers increasingly use devices such as smartwatches, continuous glucose monitors, and fitness trackers to measure sleep quality, glucose levels, nutrient intake, and heart health in real time. Use is strongly tied to age, with 75 percent of Gen Z and 73 percent of millennials saying they use such tools, against 55 percent of Gen X and 32 percent of baby boomers. The figures come from the firm's State of Food and Beverage research. With real-time feedback, people may adjust their behaviour faster, for instance drinking less after seeing a poor sleep score on a wearable following a night out. The report sees this growing access to health data as both a risk and an opportunity for consumer companies.
