Keto Diet versus the Mediterranean. Which Better?
Keto proponents claim the diet reduces appetite, melts abdominal fat, and boosts mental sharpness; once a person is over the first few days of “keto flu,” a feeling of malaise, fatigue, and brain fog. Studies have shown at least a short-term improvement in blood sugar in people on keto. Keto Diet versus the Mediterranean. Which Better?
What Is the Mediterranean Diet?
The Mediterranean diet is more of a lifestyle than a diet. Its name refers to the traditional eating pattern of people living in countries bordering the Mediterranean Sea. Although people in countries like Italy and Greece have been eating this way for centuries, the Mediterranean “diet” wasn’t popularized until the 1960s, when a group of researchers noted that people in that area of the world were exceptionally healthy and had a lower risk of many lifestyle diseases compared to Americans.
So what does the Mediterranean diet look like? It includes abundant fruits, vegetables, whole grains, beans, legumes, and healthy fats; a moderate amount of chicken, fish, eggs, and dairy; and limited amounts of red and processed meats, added sugars, and processed foods. Any foods fitting these categories fit into a Mediterranean diet; the health benefits are not exclusive to the specific foods found around the Mediterranean. Enjoying meals with others, having occasional red wine, and being physically active most days are also components of the Mediterranean diet.
What Is the Keto Diet?
The ketogenic (“keto”) diet was developed in the 1920s as a treatment for epilepsy. It’s a high-fat, moderate-protein, low-carbohydrate diet that has since been analyzed for weight loss, diabetes, cancer, Alzheimer’s disease, and more. The keto diet is characterized by a very low carbohydrate intake, with less than 5% of calories from carbs. When carbohydrate intake is extremely low, the body begins to break down fat for energy through ketogenesis, which produces ketosis. The liver turns fat into ketones for energy until you start eating carbs again.
The main foods of a keto diet include meat, fish, cheese, eggs, oils, avocados, butter, cream, nuts, seeds, and low-carb vegetables. Higher-carb vegetables, most dairy, grains, beans, fruit, and processed foods are limited or eliminated since they drive up carb intake and potentially shift the body out of ketosis.
Mediterranean Diet Drawbacks
Because the Mediterranean diet is so liberal, the lack of structure may make it challenging for some people to follow. The current Dietary Guidelines for Americans include a Healthy Mediterranean-style eating Pattern that estimates serving sizes and calorie counts. Another potential downside of the Mediterranean diet is that it may be time-consuming to prepare meals and potentially expensive, although arguably no more costly or time-consuming than the keto diet. Plus, you can incorporate frozen and canned produce and dried herbs and spices if that’s helpful to reduce food waste and prep time.
A ketogenic diet is one in which most calories come from fat (70-75%), a moderate amount from protein (20-25%), and only a small number from carbohydrates (5%).
What Can You Eat on the Keto Diet and the Mediterranean Diet?
Below, we’ve compiled a summary of what you can—and can’t—eat on each diet plan so you can compare them head-to-head.
The diet forces the body to burn fats rather than carbohydrates for energy. Typically, the carbohydrates you eat are turned into glucose in the body, which is used for energy around and in the brain. But, if you don’t eat enough carbohydrates, your body has a backup system of burning fat instead. The liver can use stored fat and the fat you eat for energy. Stored fat is broken into two parts: fatty acids and ketone bodies. Ketone bodies power the brain instead of glucose. This state of having a lot of ketone bodies in your blood is called “Ketosis.” The liver can also make or release its glucose through two processes(gluconeogenesis and glycogenolysis), as glucose is still needed for normal body function.
The Mediterranean Diet Pyramid is a nutrition guide developed by the Oldways Preservation Trust, the Harvard School of Public Health, and the World Health Organization in 1993. It summarizes the Mediterranean Diet pattern of eating and suggests the types and frequency of foods that should be enjoyed daily.
The diet is closely tied to areas of olive oil cultivation in the Mediterranean region. The pyramid, structured in light of current nutrition research and representing a healthy Mediterranean diet, is based on the dietary patterns of Crete, Greece, and southern Italy circa 1960 at a time when the rates of chronic disease were among the lowest in the world. Adult life expectancy was among the highest despite limited medical services. These findings were established in large part by scientist Ancel Keys.
The pyramid is divided into daily, weekly, and monthly frequencies but does not recommend serving sizes.
The Mediterranean diet is based on the traditional foods people used to eat in countries bordering the Mediterranean Sea, including France, Spain, Greece, and Italy.
Researchers noted that these people were exceptionally healthy and had a low risk of many chronic conditions.
Although there are no strict rules or regulations for the diet, it typically encourages fruits, vegetables, whole grains, legumes, nuts, seeds, and heart-healthy fats. Processed foods, added sugar and refined grains should be restricted.
Numerous studies have shown that the Mediterranean diet can promote weight loss and help prevent heart attacks, strokes, type 2 diabetes, and premature death.
For this reason, the Mediterranean diet is often recommended for those looking to improve their health and protect against chronic disease.
