You can expect a whole lot of perks.
New diets pop up all the time, and each has its own little niche. For example, keto is all about loading up on fats and minimizing carbs, while flexitarian is plant-based and allows little room for meat. The Blue Zone diet, one of the newer kids on the block, focuses on helping you live longer.
The Blue Zones are parts of the world where people live the longest. These areas include Okinawa, Japan; Sardinia, Italy; Nicoya, Costa Rica; Icaria, Greece; and Loma Linda, California, according to Dan Buettner, who pioneered the concept and wrote The Blue Zones Solution: Eating and Living Like the World’s Healthiest People. He broke down the dietary habits of the residents of these cities and found a commonality: They ate a lot of plants and whole foods.
It’s uncertain whether diet is the reason why people in the Blue Zones have longer lifespans, but it likely plays a role, says Scott Keatley, RD, of Keatley Medical Nutrition Therapy.
The diet does come with many health-promoting qualities, Keri Gans, RD, the author of The Small Change Diet, points out. “A diet such as this is predominately plant-based and therefore full of foods rich in antioxidants, such as fruits and veggies,” she says. “Antioxidant-rich foods have anti-inflammatory properties that may help to reduce the risk for many chronic diseases, such as heart disease and cancer. This type of diet also greatly limits foods that may lead to increased inflammation in the body, such as added sugar and saturated fats, which on the other hand are known to increase the risk for chronic disease.”
While the Blue Zone diet leans heavily on longevity, can it also help with weight loss? Here’s everything you need to know, including what you can eat and sample meal plans plus recipes.
The Blue Zone diet has some overall guidelines that you are encouraged to follow:
These habits can increase your odds of losing weight, says Karen Ansel, RDN, the author of Healthy in a Hurry. “It’s plant-based, so it’s filled with foods linked to a healthier body weight like beans, whole grains, fruits, and vegetables. The other nice thing about the diet is its focus on eating until you’re almost full, rather than stuffed, so it naturally helps with portion control,” she adds.
But how much weight you could lose on this diet—if any—really depends on what you were eating before you went on it, says Jessica Cording, RD, the author of The Little Book of Game-Changers. Still, she points out that “a plant-forward diet can be really helpful for weight management.”
All the fiber in this diet is also conducive to weight loss, Keatley says. “The emphasis on high-fiber—read: filling—foods may keep you from consuming too many calories,” he explains.
The creators of the Blue Zone diet have more or less picked features from various Blue Zone groups, one of which is located near the Mediterranean Sea, Keatley says. “They focus on plant-based foods because the population of Loma Linda, California, consumes that and some fish because the Okinawan groups eat that,” he says. “The diet limits wine, but the Greek and Sardinian groups tend to have several glasses of wine per week. So, it takes aspects of the Mediterranean diet, but pushes it to be a little more of a vegan than pescatarian lifestyle.”
The Mediterranean diet is also a “much more encompassing diet plan including all food groups,” Gans says. For example, it includes poultry, eggs, dairy, nuts, seeds, and all legumes while the Blue Zones diet limits some of these foods.
Both the Mediterranean and Blue Zone diets offer loads of perks, so either of them would be a fantastic choice, Ansel says. It’s really a matter of which one works best for you. If you prefer a little more dairy, eggs, and chicken in your life, the Mediterranean diet might be a better fit. “It might also be a good transition diet if you’d ultimately like to follow the Blue Zone plan but aren’t quite ready to go 95 percent plant-based,” she adds.

Following the Blue Zone diet guidelines will help steer you toward the right foods, but the diet specifically calls out certain ones as good options like the following.
You’ll want to limit the following foods.
While the Blue Zone diet is heavy on plant-based foods, it’s technically not vegan given that it allows for some fish, eggs, and animal products. However, you can adjust the Blue Zone diet to be vegan.
Here’s a sample three-day meal plan and some recipes to get you started.
It depends on how you approach it, and Keatley emphasizes that balance is always key. “Just because something is plant-based, vegetarian, or vegan does not mean it is going to be good for you all the time and in unlimited quantities,” he says. “Having a balance of high-energy carbohydrates like whole-grains, beans, and legumes should be balanced with other micronutrients to maintain a healthy weight and lean body mass.”
Reminder: Plant-based does not mean it is going to be good for for you all the time and in unlimited amounts.
Keep in mind that you’ll need to make sure you’re covering all of your nutritional bases if you go fully plant-based. “If you take it to the most extreme level by eliminating all animal foods, you may require a vitamin B12 supplement,” Ansel says.
The bottom line: Overall, the Blue Zone diet is a pretty solid approach. “There isn’t a downside to adding more plant foods to your diet and lowering added sugars and overly processed food,” Gans says.
