The Mediterranean diet is easy to find in the grocery store, contains nutrients that are known to enhance longevity and has other health benefits that are backed by peer-reviewed, scientific studies. Broccoli makes the list because it's one of nature's most nutrient-dense foods, with only 30 calories per cup. That means you get a ton of hunger-curbing fiber and polyphenols -- antioxidants that detoxify cell-damaging chemicals in your body -- with each serving.
Remember, coconut oil is predominantly lauric acid, which has many benefits, including antimicrobial. However, it does not convert as efficiently into ketones and therefore does not contribute much of an energy boost. Nor does it suppress hunger or help feed your brain the way C8 and C10 do. MCT oil is typically tasteless and odorless, so it can easily be added to a wide variety of dishes and beverages, from salad dressing to smoothies and vegetable juices.
Similarly, in a study in the New England Journal of Medicine, scientists followed for years the diets and health of 22,043 adults in Greece. (12) Adherence to the traditional Mediterranean diet was assessed by a 10–point scale that incorporated the key facets of the diet, including an abundance of plant food (fruits, vegetables, whole-grain cereals, nuts, and legumes), olive oil as the main source of fat, and low–to–moderate amounts of fish and poultry.
So is the Mediterranean diet still healthy? Absolutely. While this one study may have been flawed, it doesn’t change the fact that fresh fruits, veggies, lean proteins, whole grains, fish and healthy fats like olive oil (along with the occasional glass of wine!) are all foods that are proven to be good for you on their own. Together, they comprise a diet that can be terrific for your health — study or no study.
The ketogenic diet has been shown to produce beneficial metabolic changes in the short-term. Along with weight loss, health parameters associated with carrying excess weight have improved, such as insulin resistance, high blood pressure, and elevated cholesterol and triglycerides. [2,7] There is also growing interest in the use of low-carbohydrate diets, including the ketogenic diet, for type 2 diabetes. Several theories exist as to why the ketogenic diet promotes weight loss, though they have not been consistently shown in research: [2,8,9]
According to the American Heart Association, the Mediterranean diet is higher in fat than the standard American diet, yet lower in saturated fat. It’s usually roughly a ratio of 40 percent complex carbohydrates, 30 percent to 40 percent healthy fats and 20 percent to 30 percent quality protein foods. Because this balance is somewhat ideal in terms of keeping weight gain and hunger under control, it’s a good way for the body to remain in hormonal homeostasis, so someone’s insulin levels are normalized. As a byproduct, it also means someone’s mood is more likely to stay positive and relaxed, energy levels up, and physical activity easier.
The Mediterranean diet wasn’t built as a weight loss plan — in fact, because it wasn’t developed at all, but is a style of eating of a region of people that evolved naturally over centuries, there’s no official way to follow it. But it’s popular because it’s a well-rounded approach to eating that isn’t restrictive. Two of the five Blue Zones — areas where people live longer and have lower rates of disease — are located in Mediterranean cities (Ikaria, Greece and Sardinia, Italy). (2) These places are known for having some of the lowest rates of heart disease and cancer worldwide. (3)
