I Ate Like a Blue Zone Centenarian for a Week—Here’s What Changed

Monica Gray - June 25, 2025

The Blue Zones—regions where people consistently live past 100—have captivated health enthusiasts worldwide. Places like Okinawa, Sardinia, and Ikaria aren’t just known for their beautiful landscapes, but for their residents’ remarkable longevity and vitality.
Curious about what makes their diets so powerful, I embarked on a weeklong experiment to eat like a Blue Zone centenarian. My goal? To uncover not just what’s on their plates, but how these foods could transform my own health and perspective on eating.

1. Rediscovering Plant-Based Eating

Diving into the Blue Zone way of eating meant embracing meals centered on vegetables, beans, and whole grains. Each dish felt both nourishing and familiar, echoing elements of Mediterranean and vegetarian diets I’d tried before.
Lunches were often hearty bean stews, while dinners included roasted root vegetables and fresh greens. The focus on plant-based foods surprised me with its variety and depth of flavor. Learn more about the Blue Zones and their eating habits.

2. Smaller Portions, Greater Satisfaction

One transformative habit was the Okinawan practice of Hara Hachi Bu—stopping when I felt 80% full. This mindful approach to eating, rooted in Blue Zone wisdom, helped me avoid overeating and appreciate each bite more deeply.
Portion control became second nature, and I noticed increased energy without heaviness. It’s a simple principle, but one that’s strongly linked to longevity. See Mayo Clinic’s take on this powerful tradition.

3. Embracing Beans as a Protein Source

Beans quickly became the star of my meals, taking the place of meat entirely. Lentils, chickpeas, and black beans featured in everything from soups to salads, delivering a satisfying boost of protein and fiber without any heaviness.
This simple swap echoed the diets of Blue Zone centenarians, who often eat beans daily. Not only did I feel fuller for longer, but my digestion improved noticeably. Harvard Health highlights just how supercharged beans really are.

4. Minimal Processed Foods

Following the Blue Zone model, I swapped processed snacks and ready-made meals for fresh, whole ingredients. This shift wasn’t just about nutrition—it changed how my body felt each day.
With fewer additives and preservatives, my energy levels improved, and those mid-afternoon cravings nearly vanished. The difference was striking, supporting what NIH research shows about ultra-processed diets and their link to excess calorie intake.

5. Limited Meat Consumption

Meat shifted from being a mainstay to an occasional treat, much like it is in Blue Zone communities. Most of my meals were vegetarian, with fish appearing just once or twice during the week.
This adjustment was surprisingly easy, thanks to the abundance of flavor from plant-based dishes. I felt lighter and noticed less sluggishness after meals. More on Blue Zone meat intake and how it shapes longevity.

6. Savoring Local, Seasonal Produce

Each meal was built around in-season fruits and vegetables, a hallmark of Blue Zone eating. Visiting local farmers’ markets not only ensured maximum freshness and flavor, but also brought me closer to my community.
This approach added variety to my plate, encouraging me to try produce I’d often overlooked. Meals felt more vibrant, and I found myself genuinely excited to cook. CDC on seasonal eating highlights the benefits of this simple, healthful shift.

7. Enjoying Nuts Daily

Swapping processed snacks for a daily handful of nuts became a delicious new habit. Just like in Loma Linda, California—a renowned Blue Zone—this small change kept me feeling full between meals and supported my heart health.
Almonds, walnuts, and pistachios offered crunch and satisfaction without guilt. Cleveland Clinic: nuts and longevity explores how this simple snack can contribute to a longer, healthier life.

8. Drinking More Water, Less Soda

In true Blue Zone fashion, I replaced sugary sodas with water and herbal teas. This simple swap led to better hydration and a noticeable drop in sugar cravings.

9. Wine in Moderation

Channeling Sardinian and Ikarian traditions, I enjoyed a small glass of red wine with dinner most evenings. This was never about excess, but about savoring the ritual—often paired with conversation or a nourishing meal.

10. Prioritizing Breakfast

Adopting the Blue Zone approach, I made breakfast my biggest meal, followed by a lighter lunch and the smallest dinner. This shift gave my mornings a burst of energy and left me feeling satisfied well into the afternoon.
Whole grains, fruit, and nuts became staples at sunrise. The result was better focus and fewer mid-morning slumps. Johns Hopkins: Blue Zone diets outlines why meal timing matters.

11. Mindful Eating Practices

Inspired by Blue Zone traditions, I made an effort to eat slowly and intentionally—always seated at a table, free from screens. Sometimes meals were shared with music or quiet conversation, other times enjoyed in peaceful silence.
This mindful approach not only enhanced the flavor of my food, but also improved digestion and satisfaction. Each bite felt purposeful, and I ate less overall. Harvard: Mindful Eating explains the far-reaching benefits of this practice.

Shifting to mostly home-cooked meals gave me total control over what went on my plate. Using fresh ingredients, I enjoyed experimenting with family recipes and discovering new Blue Zone-inspired dishes.

13. Incorporating Herbs and Spices

Drawing inspiration from Ikaria and Nicoya, I began to season dishes with fresh herbs and spices instead of relying on salt. This shift added vibrant flavors and a powerful dose of antioxidants to every meal.
Basil, oregano, turmeric, and cilantro transformed even the simplest foods. Cleveland Clinic: Herb health benefits details how these ingredients support wellness and longevity.

14. Less Dairy, Better Digestion

Dairy took a back seat during my Blue Zone week, limited to occasional Greek yogurt or sheep’s cheese. This mirrored the modest approach found in many long-lived communities.
