Indeed, the people most likely to live 100 robust years and beyond, the citizens of Okinawa, Japan, don’t even use olive oil. They do eat a lot of fiber–rich, straight–from–the–earth foods, (14) as do other communities with high percentages of centenarians, such as the Seventh Day Adventists of Loma Linda, California; and the people of Nicoya Peninsula, Costa Rica; Icaria, Greece; and Sardinia, Italy.

The Mediterranean diet is a primarily plant-based eating plan that includes daily intake of whole grains, olive oil, fruits, vegetables, beans and other legumes, nuts, herbs, and spices. Other foods like animal proteins are eaten in smaller quantities, with the preferred animal protein being fish and seafood. Although the pyramid shape suggests the proportion of foods to eat (e.g., eat more fruits and vegetables and less dairy foods), it does not specify portion sizes or specific amounts. It is up to the individual to decide exactly how much food to eat at each meal, as this will vary by physical activity and body size. There are additional points that make this eating plan unique:
Another study, published in the New England Journal of Medicine in 2008, assigned 322 moderately obese adults to one of three diets: calorie-restricted low-fat; calorie-restricted Mediterranean; and non-calorie-restricted low-carb. After two years, the Mediterranean group had lost an average of 9 7/10 pounds; the low-fat group, 6 4/10 pounds; and the low-carb group, 10 3/10 pounds. Although weight loss didn't differ greatly between the low-carb and Mediterranean groups, both lost appreciably more than the low-fat group did.
All these benefits occurred despite the fact that MCTs are a saturated fat. There was no difference in daily exercise or consumption of total calories of protein, fat, or carbohydrates. There was no calorie restriction, yet the subjects still lost more weight. It further proves that it’s not all about the calories in food, it’s about the information!
Now olive oil known to be a healthy fat is also one of the reasons many people falsely believe the Mediterranean diet cannot help you lose weight. However, if followed correctly a Mediterranean diet not only can provide several health benefits but it can help you lose weight. Several studies have associated the Mediterranean diet with lower body fat and normal weight in children and adults.
After 12 weeks, the decrease in body weight and body fat was significantly greater in the MCT group than in the LCT group. The decrease in the area of subcutaneous fat in the MCT group was also significantly greater than that in the LCT group, which suggests that the MCT diet might be able to help reduce body weight and fat in individuals who need to lose weight.

A 2016 study in The Lancet Diabetes & Endocrinology journal that analyzed data from Predimed – a five-year trial including 7,447 adults with Type 2 diabetes or at risk for cardiovascular disease who were assigned either a Mediterranean diet supplemented with olive oil, the same diet supplemented with nuts or a control diet – found that people on the Mediterranean versions added the fewest inches to their waistlines. The olive oil folks lost the most weight.
C8 has potent anti-microbial properties (way more potent than lauric acid) to help you maintain a healthy gut, and it is the fastest to metabolize in the brain. (This is Brain Octane Oil.) Your liver does not need to process this rare type of MCT, and it only takes 3 steps for your body to turn it into ATP, the cellular fuel you use.[2] Sugar takes 26 steps. This is why Brain Octane is so good at suppressing cravings and is the most powerful oil to put in Bulletproof Coffee. You would need 4 tablespoons of coconut oil to get just one tablespoon of Brain Octane.

Fortunately, Drs. Kevin Hall and Juen Guo had the same burning question. In 2017, they analyzed the data and published a meta-analysis of controlled feeding studies that compared diets of equal calorie and protein content with variations in carbohydrate and fat content. [24] By filtering out the diet data in this way, the researchers could finally find out whether restricting carbs or limiting calories is more important when it comes to weight loss.
Add in intermittent fasting: Once you are fat-adapted, hunger pangs diminish and it is easy to go for longer periods without eating. Many people naturally stop eating breakfast — they just aren’t hungry when they wake up. The number one rule of low-carb eating is “eat when you are hungry and stop when you are full.” So if you are not hungry try fasting for 16 hours, and then eating just lunch and dinner in an 8-hour window, called a 16:8 fast. Or try eating dinner one night, than fasting until dinner the next night, doing a 24-hours fast.
Olive oil is made by crushing then pressing olives. It has been a staple of the Mediterranean diet for thousands of years. Extra-virgin olive oil comes from the first pressing of ripe olives, and, according to the Ochef website, it has less than 1 percent acid and offers the richest flavor. Virgin olive oil also comes from the first pressing, but can contain as much as 4 percent acid and its taste is slightly less smooth. The labels “light,” and “extra light” you see on bottles of olive oil refer to the color and flavor, not to how many calories or how much fat they contain. All olive oils contain the same number of calories, so choose olive oil based on your taste preferences.
Those who’ve had their gallbladder removed may need ox bile supplementation to support their body in breaking down fats[*] and aid in overall digestion. When taken with a meal, ox bile provides a concentrated source of bile which takes the place of the bile that would have been secreted by your gallbladder. As mentioned before, proper digestion is key to helping aid in weight loss and optimizing overall health and wellness.
These findings fall in line with another meta-analysis on 13 randomized controlled trials that compared low-fat and low-carbohydrate diets. The researchers found that, after six months, subjects who consumed less than 60 grams of carbohydrates per day had an average weight loss that was 8.8 pounds greater than the subjects on low-fat diets. At one year, the difference had fallen to 2.3 lb (which is consistent with what was found in the meta-analysis conducted by the Brazilian researchers).
Of course, the most famous use for MCT oil is Dave Asprey’s Bulletproof® Coffee recipe. This fat-packed coffee uses a mixture of grass-fed butter and MCT oil for a brain and energy boost. I accomplish similar results by adding coconut oil to my healthy coffee recipe, but have tried the MCT version and can vouch for its energy-boosting and brain-focus inducing properties. (Note: There are two Bulletproof® brand MCT oils: XCT Oil (C8+C10)and Brain Octane oil (Pure C8), which do contain palm but are sustainably sourced and use a super-clean steam distillation process of extraction).
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.
Your individual fat adaptation period. Remember your body needs time to become fat-adapted and that time depends on your metabolism. For instance, if you’re coming off a Standard American Diet (SAD) and your adult body has never run on ketones before, your adaptation period might take a little longer. You’ll only experience the true weight loss effects of keto when your body is actually running on ketones.

Over the past 50 years, what we think of as Mediterranean fare has changed. Many of us picture huge, three-hour feasts with multiple courses of pizza, lasagna, racks of lamb, long loaves of white bread, and endless bottles of wine. But the true Mediterranean Diet is based on the region’s traditional fruits, vegetables, beans, nuts, seafood, olive oil, and dairy—with perhaps a glass or two of red wine. That’s how the inhabitants of Crete, Greece, and southern Italy ate circa 1960, when their rates of chronic disease were among the lowest in the world and their life expectancy among the highest, despite having only limited medical services.And the real Mediterranean diet is about more than just eating fresh, wholesome food. Daily physical activity and sharing meals with others are vital elements of the Mediterranean Diet Pyramid. Together, they can have a profound effect on your mood and mental health and help you foster a deep appreciation for the pleasures of eating healthy and delicious foods.
There’s room for interpretation in the Mediterranean diet, whether you prefer to eat lower carb, lower protein or somewhere in between. The diet focuses on consumption of healthy fats while keeping carbohydrates relatively low and improving a person’s intake of high-quality protein foods. If you refer protein over legumes and grains, you have the option to lose weight in a healthy, no-deprivation-kind-of-way with a high amount of seafood and quality dairy products (that simultaneously provide other benefits like omega-3s and often probiotics).
This website is helpful I gained ten pounds just by snacking. I on the Keto diet with 15 carbs a day I stopped all snacking, stopped staying up late because it screws up cortisol / hormones which causes weight gain so I started going to bed at 9:30 on the dot. I typically eat one meal a day a green salad with either, chicken or prawns and simple homemade dressing . Sometimes I do a big glass of a low carb, a chocolate mocha protein drink with a nut milk and ice blended this does the trick. I never eat after 4:00. I have coffee with a little butter and drink lots of water I use Ketostix every other day to see if I’m still in ketosis. I did get foot cramps and increased sea salt intake and it stopped. I love fasting and going to yoga I feel clearer, lighter and just happier. Just keep with a program and you will see light at the end of the tunnel. Some people have great success with zero carbs. I have never tried it but read about it.
It also may help stave off chronic diseases, like heart disease and type 2 diabetes, as well as act protectively against certain cancers. (34) The diet is also a boon to mental health, as it’s associated with reduced odds of depression. (34) There’s even some data to suggest it can be supportive in relieving symptoms of arthritis, according to a paper published in April 2018 in the journal Frontiers in Psychology. (35)
KETO WEIGHT LOSS is designed for ketogenic and low-carb dieters looking to increase fat burning power. When following these diets, the body goes through a transition from burning glucose (sugar) for fuel to burning fat for fuel. During this phase known as “keto adaptation”, you may feel unmotivated, tired and lose focus (sometimes known as the keto flu). KETO WEIGHT LOSS was created to help fight these unwanted side effects, while assisting your body in torching fat.*†
Keep moving — In addition to ketosis, the best thing you can do for your weight-loss journey and your overall health is to get moving! It’s extremely easy to wake up, go to work, sit at a desk all day, come home, and then sit on the couch for the rest of the evening. But when you do this, you aren’t burning calories like you should if you want to lose weight. For best results, take up a combination of resistance training and cardio. Building muscle will give your metabolism a boost since muscle in your body burns more calories than fat, and cardio will further help you burn calories. And even if you don’t want to go to the gym or get outside for a run, try to get in a 30-minute walk 3-4 times per week. A 30-minute walk at a brisk pace can help you burn about 150 calories. Plus, working out will boost your mood and help you stay motivated on your health journey.
It’s also crucial, if you’re eating more fats, to make sure you eat the right kinds. A study published last year in Lancet Public Health of 15,428 adults found that low-carb diets were linked with a higher risk of dying during the study period if people replaced carbs with animal-based fats and protein. But those who replaced carbs with fat and protein from plants—such as avocados, olive oil, nuts, and seeds—had a lower risk of dying.

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.

MCTs, also called “MCFAs” for medium-chain fatty acids, are believed to be largely missing from the diets of people eating “standard Western” diets, most likely because the public has been led to believe that all forms of saturated fats are potentially harmful. However, recent research has shown a lot of evidence about the real truth regarding saturated fats.
