If you've been cooking with vegetable oil or coconut oil, make the switch to extra-virgin olive oil. Olive oil is rich in monounsaturated fatty acids which may improve HDL cholesterol, the "good" type of cholesterol. HDL cholesterol ferries "bad" LDL particles out of arteries, according to a 2017 study in Circulation. Use olive oil in homemade salad dressings and vinaigrettes. Drizzle it on finished dishes like fish or chicken to boost flavor. Swap butter for olive oil in mashed potatoes, pasta, and more.
The Mediterranean Diet is not a diet. It is a lifelong habit. Something you must stick to as a creed. Decades ago, this was the usual way of life of the communities around the Mediterranean Basin. It was the everyday life in countries like Spain, Italy or Greece. Its major points were physical activity, healthy nutrition and calm attitude. And not much money to throw away.
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.
Generally a good source of fiber, vitamin C and antioxidants, fresh fruit is a healthy way to indulge your sweet tooth. If it helps you to eat more, add a little sugar—drizzle slices of pear with honey or sprinkle a little brown sugar on grapefruit. Keep fresh fruit visible at home and keep a piece or two at work so you have a healthful snack when your stomach starts growling. Lots of grocery stores stock exotic fruit—pick a new one to try each week and expand your fruit horizons.
“Limited and not conclusive scientific evidence suggests that eating about 2 tablespoons (23 grams) of olive oil daily may reduce the risk of coronary heart disease due to the monounsaturated fat in olive oil. To achieve this possible benefit, olive oil is to replace a similar amount of saturated fat and not increase the total number of calories you eat in a day.”
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.

Don’t get it wrong — just about all the cheap and abundant oils in coconut oil are good for you, which is why coconut oil is high on the list of Bulletproof foods! The problem is that studies show you can’t get enough of the really useful MCTs from just eating coconut oil or a so-called “MCT oil” that is diluted with lauric acid, a useful, but cheap, and hugely abundant part of coconut oil that is marketed as an MCT oil.
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.
While each person’s keto journey will be unique, the fact remains: going keto is an effective way to shed extra weight and kickstart a life with better health. You’ll look better, feel better, and perform better in everyday life. But as with any diet, there will be times when the weight effortlessly slips off, and other times when the weight stubbornly hangs on. When you hit those weight loss stalls, the best thing to do is stick with it and stay on track. The ketogenic diet works and the health benefits of losing weight could transform your life.
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]
It’s estimated that over 50% of people are deficient in Vitamin D worldwide[*]. Although Vitamin D doesn’t play a major role in whether or not you are in ketosis, it is responsible for regulating immunity, inflammation, hormones and helping with electrolyte absorption[*][*] — all factors important for weight loss and overall health. Additionally, studies support the direct benefits of vitamin D for weight loss[*][*][*]. You can check your Vitamin D levels with a simple blood test and then supplement accordingly. When supplementing, choose Vitamin D3 as it is the form that’s best absorbed by your body[*][*].
Some studies have proposed that women’s weight gain in midlife is more a factor of aging — which impacts both sexes — than of menopausal changes in hormones. Other studies note, however, that declining estrogen (estradiol or E2) at menopause changes women’s energy needs and metabolism, changes their location of body-fat accumulation from the hips to abdomen, and is associated with an increased rate of metabolic syndrome.
Due to the high-quality design and data of the study, it was published in the Journal of American Medicine, one of the most prestigious research journals in the world. The research team stated that “in this study of overweight and obese premenopausal women, those assigned to follow the Atkins diet had more weight loss and more favorable outcomes for metabolic effects at 1 year than women assigned to the Zone, Ornish, or LEARN diets.” 
"I always make an assessment of whether or not the cheat is worth it and 99 percent of the time, it’s not. If I do have a cheat meal, I don't worry about what the scale says afterward. I want to be happy with the decision before I make it, during it, and after I make it. A lot of it is living with your decisions and not beating yourself up over it."
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”.
Good fats in olive oil, nuts, and fish are beneficial for our health, and science is continually proving this to be the case. Recent studies have shown that consuming a Mediterranean diet with extra virgin olive oil leads to lower rates of cardiovascular diseases and cancer. And now there is evidence that the healthy fats in olive oil is linked to weight loss.
Combine that with the fact that your body is excreting more water, and you have a potential recipe for clogged pipes. You can keep things moving by getting some fiber from keto-friendly foods like avocado, nuts, and limited portions of non-starchy vegetables and berries, says David Nico, PhD, author of Diet Diagnosis. Upping your water intake helps, too.
Additionally, they remarked that “concerns about adverse metabolic effects of the Atkins diet were not substantiated within the 12-month study period.”  They acknowledged that more research needs to be done on the long-term effects on cardiovascular and metabolic health especially on men. However, their study supports the idea that a low-carbohydrate diet can help you lower body mass and body fat better than higher-carbohydrate alternatives.
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).
Unsaturated fatty acids, whether monounsaturated or polyunsaturated, can lower your levels of "bad" cholesterol (which decreases your risk of heart disease) if you eat them instead of saturated fatty acids, Hughes says. Saturated fat -- found mostly in animal products and in palm and coconut oils -- is the main dietary cause of high blood cholesterol, according to the American Heart Association.
