Among baby boomers, the share rose to 41 percent from 29 percent in 2022. The most popular dietary patterns included high protein (18 percent), mindful eating (17 percent), calorie counting (12 percent), clean eating (12 percent), and intermittent fasting (12 percent), highlighting the growing health-conscious dietary behavior. Therefore, rising health consciousness is driving the OTC diet products market.
