The ketogenic or “keto” diet is a low-carbohydrate, fat-rich eating plan that has been used for centuries to treat specific medical conditions. In the 19th century, the ketogenic diet was commonly used to help control diabetes. In 1920 it was introduced as an effective treatment for epilepsy in children in whom medication was ineffective. The ketogenic diet has also been tested and used in closely monitored settings for cancer, diabetes, polycystic ovary syndrome, and Alzheimer’s disease.
The Mediterranean diet has received much attention as a healthy way to eat, and with good reason. The Mediterranean diet has been shown to reduce risk of heart disease, metabolic syndrome, diabetes, certain cancers, depression, and in older adults, a decreased risk of frailty, along with better mental and physical function. In January, US News and World Report named it the “best diet overall” for the second year running.

Keep in mind, too, that all oils are a mixture of saturated, monounsaturated, and polyunsaturated acids (though they’re usually called by the name of the fatty acid that is most abundant). Olive oil is about 14% saturated fat, so if you’re pouring olive oil into your skillets and food every day, you’re likely consuming significantly more artery-clogging saturated fat than you realized.
While keto diets minimize sugar and other food sensitivities, they often allow full-fat dairy such as yogurt that, for some people, can stall fat loss. And some packaged keto-friendly foods (yes, there's a whole industry of keto-friendly cookies, candy, and other junk food!) can contain gluten, artificial sweeteners, and other reactive ingredients. These foods and additives cause dysbiosis (an imbalance between good and bad bugs), leaky gut syndrome, and increase insulin resistance, which raises blood sugar levels—stalling weight loss. Read your labels carefully: Food sensitivities can be sneaky and hide in foods that you would never suspect, like mustard.
Research shows that greater adherence to the traditional Mediterranean diet, including plenty of monounsaturated fats and omega-3 foods, is associated with a significant reduction in all-cause mortality, especially heart disease. A striking protective effect of a Mediterranean diet rich in alpha-linolenic acid (ALA) from olive oil has been shown in many studies, with some finding that a Mediterranean-style diet can decrease the risk of cardiac death by 30 percent and sudden cardiac death by 45 percent.

• Other research suggests MCTs help with weight loss by reducing your appetite. As reported by Mental Health Daily:12 "Some scientists speculate that MCT acts on various hormones such as: cholecystokinin, gastric inhibitory peptide, pancreatic polypeptide, peptide YY and neurotensin. The precise mechanism of action of MCTs remains unknown, but it is known to induce satiety and reduced appetite compared to [LCTs]."
To maximize the benefits of olive oil, Palinski-Wade mixes six servings a day with other ingredients scientifically proven to blast belly fat — including lean protein (which helps keep belly-fat hormones low) and dairy (rich in an amino acid that speeds the release of ab fat). On the olive oil diet plan, you’ll also enjoy berries, greens, beans, potatoes, and other plant foods that come packed with belly-fat-fighting antioxidants.
