Yet it’s an incredibly well-rounded way to lose weight that ditches gimmicks and doesn’t require calorie or macronutrient counting as other diets do. And with the emphasis on healthy fat, it’s satisfying, too. That said, the 2019 U.S. News & World Report Best Diets ranked the Mediterranean diet as No. 1 for Best Diets Overall and it ranks 17 in their list of Best Weight-Loss Diets. (3) The reviewers note that it’s not a slam dunk, and all depends on how you eat. Even healthy diets like the Mediterranean aren’t free-for-all eating plans.
The second reason is arguably more important: Vegies taste better with olive oil, so people are likely to eat more. “My rule of thumb is one tablespoon of extra-virgin olive oil to one cup of veg,” Flynn says, adding that sautéing them or roasting are tasty options, plus these methods maintain much of their nutrient value. “Eating veg like this fills you up and stops you being hungry.” An added bonus, she says, is fibre from the veg also improves bowel regularity.
She went on to research whether a plant-based olive oil diet would improve risk factors for chronic disease, including breast and prostate cancers, relative to a lower fat diet. In one major study of 44 women with breast cancer, participants were assigned either a conventional diet where less than 30 percent of calories came from fat or a plant-based olive oil diet. The women followed the diets for eight weeks of weight loss and then could choose which they wanted to continue on for six months of follow-up. Somewhat surprisingly to Flynn, a strong majority of the women chose her diet, saying that the meals tasted better, were easy to prepare, inexpensive, and could be used both for everyday eating and when entertaining. Moreover, those who have tried to adopt the plant-based olive diet in both research and outpatient settings have mentioned feeling better after just one day following it, which is a powerful motivator for lasting behavior change.

A: You’ll find a detailed menu earlier in this article (also, recipes from Everyday Health!), but generally, you’ll want to make plants and whole grains the stars of your plate. If you look at a Mediterranean diet food pyramid, sweets are up top (indicating they should make up only a small part of your diet), followed by meat and dairy, and then fish. Last are fruit, veggies, and whole grains (suggesting they can be eaten liberally). Also, enjoying food with friends and family is a tenet of the eating approach, so make your meals a social affair!


Consuming three tablespoons of EVOO isn’t enough to start shedding the kilos, Flynn says, explaining that the weight-loss effect kicks in when it’s combined with a healthy Mediterranean-style diet. This is rich in vegetables, fruit, legumes and whole grains, moderate in dairy and low in meat (about three serves of white meat or fish a week for women, and red meat only once or twice a month).
