Actress Kristen Bell has a simple trick for stabilizing her blood sugar — and it’s gaining attention. Her “Nobody Wants This” co-star Justine Lupe revealed Bell’s go-to hack on the Emmys 2025 red carpet.
What Happened
During an interview with E! News correspondent Zuri Hall, actress Justine Lupe shared that Kristen Bell is deeply invested in biohacking — a lifestyle trend centered on optimizing health through diet, supplements, and behavior changes. According to Lupe, Bell has mastered ways to manage her glucose levels, especially when indulging in carbs like pasta.
Who Is Kristen Bell?
Kristen Bell, best known for her roles in The Good Place, Veronica Mars, and Disney’s Frozen, is widely admired for balancing her Hollywood career with family life and wellness advocacy. Beyond acting, she has been outspoken about mental health, nutrition, and practical approaches to living a healthier lifestyle.
Kristen Bell’s Biohacking Approach
Bell reportedly “preloads” her body with leafy greens — such as spinach — before eating carbohydrates. This fiber-first strategy slows the absorption of glucose into the bloodstream, reducing spikes and crashes in blood sugar. Nutrition experts say the same effect can also be achieved with apple cider vinegar or fiber supplements like Metamucil.
Registered dietitian Amy Shapiro told the New York Post that there’s solid science behind Bell’s habit. “Preloading the body with fiber can slow glucose absorption, leading to steadier blood sugar levels and fewer cravings,” she explained. Stable blood glucose can also improve focus, mood, and fullness while reducing the risk of type 2 diabetes, insulin resistance, and cardiovascular disease.
Public Reactions and Growing Trends
Bell’s biohacking trick has sparked interest online, especially as “fibermaxxing” — boosting daily fiber intake — becomes a rising wellness trend. Health professionals, including holistic nutritionist Robin DeCicco, recommend adding color to meals with vegetables, fruits, nuts, and seeds to increase fiber naturally. However, experts caution against overloading too quickly, as excess fiber may cause digestive discomfort.
Expert Advice and What Happens Next
While Bell’s fiber-first hack is safe for most people, dietitians emphasize that biohacking should be individualized. Apple cider vinegar, for example, may irritate the stomach in some individuals. Experts suggest starting with whole-food fiber before turning to supplements or vinegar-based solutions.
As Bell’s wellness habits continue to gain attention, nutritionists see this as an opportunity to highlight the importance of balanced eating and blood sugar management.
