The findings below have been limited to research specific to the ketogenic diet: the studies listed contain about 70-80% fat, 10-20% protein, and 5-10% carbohydrate. Diets otherwise termed “low carbohydrate” may not include these specific ratios, allowing higher amounts of protein or carbohydrate. Therefore only diets that specified the terms “ketogenic” or “keto,” or followed the macronutrient ratios listed above were included in this list below. In addition, though extensive research exists on the use of the ketogenic diet for other medical conditions, only studies that examined ketogenic diets specific to obesity or overweight were included in this list. (This paragraph was added to provide additional clarity on 5.7.18.)
Hallberg suggests caution, however, around very long fasts lasting multiple days. “If you are skipping meals because you are not hungry from doing a proper low-carb, high-fat diet that is just fine.” She is concerned, however, about very long fasts in which people are ignoring hunger signals and for the potential for a dangerous physiological fluid and electrolyte imbalance called refeeding syndrome that can arise after very long extended fasts, lasting many days, when normal eating is resumed.
Because this is an eating pattern – not a structured diet – you're on your own to figure out how many calories you should eat to lose or maintain your weight, what you'll do to stay active and how you'll shape your Mediterranean menu. The Mediterranean diet pyramid should help get you started. The pyramid emphasizes eating fruits, veggies, whole grains, beans, nuts, legumes, olive oil, and flavorful herbs and spices; fish and seafood at least a couple of times a week; and poultry, eggs, cheese and yogurt in moderation, while saving sweets and red meat for special occasions. Top it off with a splash of red wine (if you want), remember to stay physically active and you're set.
One of the ways to do this that is yielding promising results in research is the ketogenic diet. In a 2017 study evaluating the ketogenic diet in the management of diabetes, researchers showed the diet had the potential to decrease blood glucose levels, the rudimental key to minimizing the occurrence and diagnosis of diabetes. This was further supported in a study evaluating the long-term effects of the ketogenic diet in obese patients, offering similar results in its ability to lower blood glucose levels, as well as decreasing total cholesterol and triglyceride levels.
Olive oil does not burn fat. It has no chemical properties that will magically dissolve the calories in that tiramisu you had for dessert. Taking a spoonful of olive oil before a meal, as some fad diets suggest, simply acts as a laxative, which plays to the mistaken belief that the faster food moves through you, the fewer calories your body will absorb. It simply doesn’t work that way. Losing weight means taking in fewer calories than you burn, no matter how many of them come from olive oil.
Dr. Hallberg notes that vigorous exercise can sometimes create a false weight plateau. “If you are exercising to the point of getting sore, you are tearing muscle — which is a good thing, that is how we build muscle, by micro-tears.” But in order to deal with that, the body sets off a small inflammatory response, which causes people to retain fluid. “So after a vigorous workout you can jump up a few pounds overnight. It is not a real plateau, it is a pseudo plateau.”
Your daily habits. Your daily habits will make or break your weight loss efforts. Consistency is the key to keto success. Are you eating clean keto foods or high-fat junk foods with low-quality ingredients? Are you watching out for hidden carbs? Are you exercising? Eating the right foods in the right amounts for your goals and adding more physical activity to your daily life are the most important pieces of a smooth and successful body transformation.
This meta-analysis also provides us with an explanation for why keto and low-carb diets have not always been found to confer better weight loss than low-fat diets. When protein and calories are controlled, changes in weight loss results remain relatively equal. This not only supports the theory that calorie deficits are the key to weight loss, but it also provides evidence against the hypothesis that carbs and insulin are the cause of obesity. [25]
The premise of the ketogenic diet for weight loss is that if you deprive the body of glucose—the main source of energy for all cells in the body, which is obtained by eating carbohydrate foods—an alternative fuel called ketones is produced from stored fat (thus, the term “keto”-genic). The brain demands the most glucose in a steady supply, about 120 grams daily, because it cannot store glucose. During fasting, or when very little carbohydrate is eaten, the body first pulls stored glucose from the liver and temporarily breaks down muscle to release glucose. If this continues for 3-4 days and stored glucose is fully depleted, blood levels of a hormone called insulin decrease, and the body begins to use fat as its primary fuel. The liver produces ketone bodies from fat, which can be used in the absence of glucose. [1]
The go-to protein in the Mediterranean diet is fish. In particular, this diet emphasizes fatty fish like salmon, sardines, and mackerel. These fish are rich in heart- and brain-healthy omega-3 fatty acids. Even those fish that are leaner and have less fat (like cod or tilapia) are still worth it, as they provide a good source of protein. If you currently don't get a lot of fish in your diet, an easy point of entry is to designate one day each week as "fish" night. Cooking fish in parchment paper or foil packets is one no-fuss, no-mess way to put dinner on the table. Or try incorporating it in some of your favorite foods, like tacos, stir-frys, and soups.
Finally, watch your protein intake, it’s very easy to go over on that and excess protein will be converted to sugars in your body (so it’s fine if you work out a lot but if you don’t then just be aware and don’t go overboard). It’s practically impossible to eat too much good fats (avoid trans fats like the plague and try to limit polyunsaturated too as too much of them can promote inflammation in the body and unfortunately they’re in lots of stuff), fats are so satieting though that you’ll nearly always feel way too full before you can eat too much of them (provided the food that they’re in isn’t secretly hiding carbs and protein too, I.e. be careful with the kind of nuts you eat, macadamia only have 5 grams of carbs per 100g but cashews have 20+ so a couple big handfuls of those will nearly knock you out of ketosis like that!)

Τhe number one concern I get when I present or suggest using plenty of olive oil in the recipes I post here, is worrying about the calories and fat. Too much fat and you will gain weight, right? Well, no not exactly. As I have explained, when you have one of the many vegetable based Greek dishes which are made with vegetables and olive oil, the percentage of fat will be somewhat high because the calories from the vegetables is so low, but overall the calories balance out. As Dr. Antonia Trichopoulou, M.D., Ph.D., top Mediterranean diet researcher and one of the developers of the Oldways Mediterranean Pyramid, has said “Certainly olive oil has many calories, but a diet can be followed that can include oil while staying within normal limits calorie wise”.
There’s been no shortage of coconut oil uses and treatments proven by recent research — it provides not only MCTs (especially abundant levels of lauric acid), but also antibacterial properties, antioxidants, anti-inflammatories and more. The difference between MCT oil and coconut oil is that MCT oil is much more concentrated and contains mostly capric acid and caprylic acid. While coconut oil certainly has MCTs in it, concentrated MCT oil is almost entirely MCTs.
The Harvard pyramid is based on the Mediterranean diet. Its structure came from the diets of the inhabitants of Crete and Southern Italy in the 1960’s. The study was presented in 1993 by Walter Willett of the Harvard School of Public Health at the International Conference on the Mediterranean Diet held in Cambridge Massachusetts. Note that oil is one of the basic components, in direct opposition to the current USDA pyramid. This pyramid has enjoyed a decade of increasing acceptance.
The fatty acids termed MCTs and lauric acid act somewhat differently in the body, although in the U.S., coconut oil and MCT oil manufacturers are legally allowed to claim that lauric acid is a type of MCT. Some people claim that lauric acid doesn’t biologically act like other forms of shorter MCTs (or at least as quickly), which is one reason why MCT advocates believe that MCT oil is somewhat superior.

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.
Just like most health issues, many different factors contribute to obesity. The factors most responsible for the obesity epidemic seem to be our genetics and the environment, and how they interact to create our eating behavior. To gain a deeper understanding of how they contribute to obesity, let’s explore the organ responsible for our eating decisions — the brain.
Seems to be working well. Mixes well with cold liquids, which is nice, and doesn't leave oily lips as much as coconut oil does. Do be careful about using too much, or using it with too empty a stomach. I recommend having food in your system if you are going to take this (unless you intentionally need a good cleaning out, then please take a double dose and you are guaranteed results!)

Many versions of ketogenic diets exist, but all ban carb-rich foods. Some of these foods may be obvious: starches from both refined and whole grains like breads, cereals, pasta, rice, and cookies; potatoes, corn, and other starchy vegetables; and fruit juices. Some that may not be so obvious are beans, legumes, and most fruits. Most ketogenic plans allow foods high in saturated fat, such as fatty cuts of meat, processed meats, lard, and butter, as well as sources of unsaturated fats, such as nuts, seeds, avocados, plant oils, and oily fish. Depending on your source of information, ketogenic food lists may vary and even conflict.
A randomized control study in 2017 examined the effects of a ketogenic diet combined with Crossfit training on body composition and performance. Results from this study concluded that subjects following a low-carbohydrate ketogenic diet (LCKD) significantly decreased body weight, body fat percentage and fat mass compared to those in the control group[*].

I'm not usually a fan of prescribed "diets"-I live by more of the anti-diet mantra. Call me jaded, but the word "diet" has a bit of a negative connotation these days, with "fad" and "restrictive" usually preceding it. So, when I had the chance to give Dr. Axe's new Keto360 program a two-week test run, I did some serious digging on the ketogenic diet and whether it's healthy.
Mediterranean diet is a generic term based on the typical eating habits in the countries that border the Mediterranean Sea. Elements include dairy products, fish and poultry being more common than red meat; fruits, vegetables, bread and other cereals, potatoes, beans, nuts and seeds; use of olive oil; wine consumed in low to moderate amounts. These diets have similarities to the American Heart Association's dietary recommendations, except a relatively high percentage of calories in Mediterranean-style diets come from fat.
You may also want to try a cyclical keto diet, or carb cycling. You follow the standard keto diet for 6 days of the week, when you eat less than 50 grams of net carbs a day. But on one day of the week, you increase your carb intake to roughly 150 grams of net carbs. Doing this satisfies any carb cravings you might have, making it easier to sustain keto in the long-run. Learn more about the benefits of carb cycling and weight loss here.

Dr. Fung suggests not doing the same fasting routine, day after day, but to “switch it up”; 16:8 one day, 24 hours IF the next, then a day of regular eating. That is because the body has a strong physiological drive to seek homeostasis — energy balance. “Whenever the body is exposed to a constant stimulus, it will become acclimated to it,” he says.

We now know that ideally MCT oils like coconut oil should actually be consumed every day. Certain saturated fats, especially MCTs and other healthy fats found in things like coconut oil or grass-fed beef, are in fact easier to digest than long-chain triglycerides (LCTs) and might even have more benefits related to heart health, obesity prevention and brain health, too.

A 2010 study in Diabetes, Obesity and Metabolism assigned 259 overweight diabetics to one of three diets: a low-carb Mediterranean diet, a traditional Mediterranean diet or a diet based on recommendations from the American Diabetes Association. All groups were told to exercise 30 to 45 minutes at least three times per week. After a year, all groups lost weight; the traditional group lost an average of about 16 pounds while the ADA group dropped 17 pounds and the low-carb group lost 22 pounds.
As for the type of MCT oil to take, I prefer the more expensive C8 (caprylic acid) oil over those containing both C8 and C10. Avoid cheaper versions containing C6. Even a 1 to 2 percent concentration of C6 can contribute to GI distress. If you want C12 (lauric acid) for its anti-microbial and anti-inflammatory activity, add coconut oil to your diet, which is less expensive and more versatile than MCT oil.
The Mediterranean diet is most famous for its benefit to heart health, decreasing the risk of heart disease by, in part, lowering levels of “bad” LDL cholesterol, and reducing mortality from cardiovascular conditions. It’s also been credited with a lower likelihood of certain cancers, like breast cancer, as well as conditions like Parkinson’s disease and Alzheimer’s disease. (1)
It's important to realize that MCT oil will not produce weight loss miracles all on its own. However, it is an excellent addition to an otherwise healthy diet. Moreover, many consider MCTs "the ultimate ketogenic fat," as it allows you to eat slightly more net carbs while still staying in nutritional ketosis. Without MCTs, you'd have to cut carbs more drastically in order to maintain ketosis.

Looking for that quick burst of energy? MCTs are an especially beneficial supplement for fueling physical exertion, given their high energy density content, rapid rate of absorption and quick metabolic conversion into cellular energy. Additionally, MCTs can be quickly mobilized in the post-exercise recovery phase to rebuild muscles and prevent the breakdown of protein that can occur when the body is putting a maximum demand on the body’s energy reserves.


Until recently it was thought these antioxidant polyphenols acted directly on genes and blood vessels. But it turns out that they also work via our gut microbes that make up our microbiome. This is the community of trillions of diverse bacteria which live in our large intestine. They feed off the different polyphenols and produce other small chemicals (short chain fatty acids) that dampen down inflammation and help our immune system.
This research also demonstrated that the monounsaturated fatty acid oleic acid (olive oil is 78% oleic acid) resulted in a marked increase in LPS attached to chylomicrons in the bloodstream. Chylomicrons, also known as cholesterol remnants, are large, fat-rich lipoprotein particles that research has found contribute to the growth of cholesterol-filled plaques. (8) After a fatty meal, the blood is so full of chylomicrons that it turns milky, like a strawberry shake.
Then there’s what you won’t eat. Palinski-Wade gives your body a break from the worst waist-plumping culprits. That means you’ll skip sweeteners and processed starch, which set off blood-sugar spikes strongly linked to belly-fat storage. Trans fats and red meat are also out, since both can worsen a type of cellular inflammation and make belly-fat hormones go haywire.
