Serena Williams has one word top of mind when it comes to health – longevity.

The 44-year-old tennis star opened up about her experience with GLP-1 medications in August after partnering with healthcare company Ro. She’s also teamed up with Lingo by Abbott, a continuous glucose monitor (CGM) that tracks blood sugar levels.

After she stopped playing tennis, she became obsessed with healthy eating and living. She’s used Lingo for years, and tracking her health data has empowered her to make more informed food choices and leave the word “diet” behind.

More than 80% of people with prediabetes don’t know they have it, as it often has no symptoms. However, it’s very common. More than 1 in 3 U.S. adults have prediabetes. While it’s possible to reverse prediabetes, it’s typically not possible to reverse diabetes complications, making prevention and proper management essential.

It’s an issue that hits close to home for Williams, who has a family history of diabetes. Lingo’s mission is to help people understand how their body reacts to different dietary choices, which sometimes can reveal early signs worth paying attention to.
