As evidence continues to mount affirming that inflammatory substances in the blood promote plaque growth, plaque rupture, and clot formation, all of which likely increase the risk of heart attacks, “we’ve got to start asking ourselves: ‘Is any fat, even so-called good fats, beneficial in terms of preventing heart attacks and strokes?'” says Kimberly Gomer, MS, RD, Director of Nutrition at the Pritikin Longevity Center.
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 Mediterranean diet might help you lose weight. While some people fear that eating a diet like the Mediterranean diet that is relatively rich in fats (think olive oil, olives, avocado and some cheese) will keep them fat, more and more research is suggesting the opposite is true. Of course, it depends on which aspects you adopt and how it compares to your current diet. If, for instance, you build a "calorie deficit" into your plan – eating fewer calories than your daily recommended max or burning off extra by exercising – you should shed some pounds. How quickly and whether you keep them off is up to you.
A study in the Journal of Lipid Research conducted at the University of Kentucky clearly demonstrated in animals that a high-fat diet promoted the absorption from the gut of lipopolysaccharides (LPS), toxic substances that are part of bacterial cell membranes. That’s troubling because high levels of LPS trigger immune cells to increase inflammation. (7)
For Brown University researcher and Associate Professor of Clinical Medicine Dr. Mary Flynn, the development and advocacy of a plant-based, olive oil diet was at one time considered outrageous. In the 1990s when the notion of consuming low-fat and fat-free foods for health was gaining widespread popularity, Flynn, who is also a nutritionist at The Miriam Hospital, was a vocal dissident. She openly expressed her concerns that this eating pattern was largely unsupported by sound science, even though many others in her field opposed her views. “I know that people in the nutrition community thought I was a near heretic,” Flynn says.
I've been on Ketogenic diet now for almost 4 wks. Iv'e lost 6 lbs., my diabetes 2 is in total remission with a morning fasting glucose reading of 92. I'm off my high blood meds they are no longer needed. The eczema inside my ears has totally disappeared! I have no problem with not eating carbs because after the 4th day with almost zero carbs, I no longer crave them. The only last question I have is ................will my high cholestrol get worst?? I'll post another comment after I have my blood work done in one more month.
Polyphenols are antioxidant plant compounds that are linked with better heart health, including less oxidative stress. Oxidative stress is a process that inflames the arteries and heightens the risk of plaque rupture and heart attacks. Plant sterols are another plant chemical that interferes with cholesterol absorption from the gut and helps lower LDL cholesterol.
In 2017, Drs. Kevin Hall and Juen Guo published a meta-analysis of controlled feeding studies that compared diets of equal calorie and protein content with variations in carbohydrate and fat content. By designing the study in this way, the researchers could finally find out whether restricting carbs or limiting calories is more important when it comes to weight loss.
In this new study published in the European Journal of Nutrition, researchers from the Federal University of Viçosa in Brazil, had a group of middle aged, overweight women receive a high fat breakfast that included 25 ml of oil. One group was given olive oil while the other group was given soybean oil. The oils were added to shakes that were consumed every morning. The participants were following a calorie restricted diet prescribed by a dietitian. After 9 weeks on this diet, both groups had lost weight, although the olive oil group had lost more weight but also more body fat. In fact, the olive oil group had 80% more body fat loss than the soybean oil group. The researchers noted that the results indicate that extra virgin olive oil should be included into calorie restricted programs for obesity treatment.
Key Takeaways: Two large-scale meta-analysis indicate that people who consume a low-carb diet (<50 g carb/day) lose a slightly larger amount of weight compared to people eating a low-fat diet over 12-month span. Neither meta-analysis assessed the loss in body fat percentage within each diet and which other dietary of exercise interventions promoted weight-loss when coupled with the ketogenic diet.
A 2018 study published in the journal Molecular Psychiatry found evidence that healthy dietary choices, those in line with eating the Mediterranean diet, can help reduce the risk for depression. (12) Researchers involved in the study investigated the mental-health effects of adherence to a range of diets — including the Mediterranean diet, the Healthy Eating Index (HEI), the Dietary Approaches to Stop Hypertension diet (DASH diet), and the Dietary Inflammatory Index. They found that the risk of depression was reduced the most when people followed a traditional Mediterranean diet and overall ate a variety of anti-inflammatory foods.
"Even though it's called the Mediterranean diet, it's not really a diet," said Atlanta registered dietitian Rahaf Al Bochi, a spokeswoman for the Academy of Nutrition and Dietetics. "It doesn't tell you what to eat and not eat. It's a lifestyle that encourages consuming all food groups but gives more weight to those which have the most health benefits."
With the importance of weight loss in the back of your mind, and an understanding of some of the factors that impact weight loss, we can now look at the amount of weight you can expect to lose on keto. This guide is based on the assumption that someone is following a strict keto diet where 75% of their calories come from fat, 20% comes from protein, and 5% comes from carbohydrates.
The cheaper forms of olive oil (those labelled regular or virgin) didn’t show any benefit – it had to be extra virgin. The difference between the grades of oil lies not just in the lower acidity, freshness and richer taste but in the number of chemicals released called polyphenols. High grade extra virgin oil, especially if cold extracted, has around 30 polyphenols that act as antioxidants, which reduce inflammation and also help reduce the effects of aging particularly on the heart and brain.
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.
Love this stuff-use in my BP coffee every morning, and it is the only thing that has changed my body composition. Since I have been very fit my entire life, very little affects me (good or bad) but since I have gotten older this is the only thing so far that has affected by over body fat distribution. Granted it is slight (only I can tell) but that means I am that much healthier, so I am a happy customer. Plus I contacted the company to request ratios of the oil contained, and I got a prompt reply. Order a 2nd bottle. Added bonus- it truly is tasteless, which means I can add to my kids baking and they don't complain :)
Minerals/Electrolytes: Adopting a ketogenic diet will change the way your body uses (and loses) certain minerals. Not replacing these minerals can lead to symptoms of the “keto flu” such as lightheadedness, headaches, constipation, muscle cramps and fatigue. Refer to this article for tips on how to replace common minerals such as sodium, potassium, magnesium and calcium.
You've probably heard of the Mediterranean diet, but do you actually understand the science behind it? Full of diverse plant-based foods, healthy fats, whole grains, and yes—the occasional glass of red wine—the Mediterranean diet is widely embraced by top medical professionals and experts. This age-old eating habit is deeply rooted in the coastal cuisines of Mediterranean countries such as Greece, Spain, Italy, France, and northern Africa.
Day 8: I'm still struggling to find a morning beverage that I enjoy and that keeps me full, so I try flavorless collagen protein powder with my coffee plus a splash of macadamia nut milk. It still isn't the same as a French press with cream, but it's a win! On the solid-food front, I'm starting to get a little grossed out about all the meat I've eaten in the past week. It's more than I'd normally eat in three times as long. Lamb burgers, turkey lettuce-wrap tacos, chicken salads. My digestion is off (even though I take probiotics every morning), so Dr. Axe recommends his Keto Digest supplements at lunch. They contain fat-digesting enzymes to help break down the extra fat and protein that my body isn't used to consuming, and it helps.
According to the US FDA, having two tablespoons of extra virgin olive oil daily may reduce the risk of heart disease, due to its monounsaturated fat content. Some of the antioxidants present in extra virgin olive oil like oleocanthal and oleuropein are known for their anti-inflammatory action and help in reducing the levels of bad cholesterol which can be a risk factor for heart disease.
For example, the large Greek EPIC study investigated which components of the Mediterranean diet were most beneficial and found that monounsaturated fats like olive oil were not stars. (11) Following 23,349 people for 8.5 years, the scientists demonstrated that only 11% of the benefit from a Mediterranean diet came from a high ratio of monounsaturated to saturated fats, and all of the monounsaturated fats were not olive oil. The biggest health benefits came from high vegetable intake, low meat intake, and moderate alcohol consumption.
More serious: Scientists have documented several cases in which a condition called ketoacidosis occurred as a result of a very low-carb diet. In ketoacidosis, the body produces more ketones than it can use for energy, and they build up in the blood, becoming toxic. If untreated, ketoacidosis can cause heart attacks, kidney failure, or fluid buildup in the brain.
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.
Dr. Westman never brings up exercise as a first step in weight loss. He wants patients to focus on the diet first. “But later on, if things are no longer working well and there is still significant weight to lose, I bring up the E-word, exercise. But I try to get them back to things that are fun for them. Exercise will help you get through a plateau.”
In the United States, the Mediterranean diet’s popularity continues to rise alongside a growing need for healthier eating patterns and lifestyles. The Centers for Disease Control (CDC) confirms heart disease as the leading cause of death in America for men and women, due to obesity, poor diet, lack of physical activity, diabetes, high levels of bad LDL (low-density lipoprotein) cholesterol, and more. In the 1970s, U.S. physiologist Ancel Keys first linked a Mediterranean-style diet and better cardiovascular health through his “Seven Countries Study,” but his theory would not catch on until several decades later. In the 1990s, non-profit Oldways Preservation Trust introduced the Mediterranean Diet pyramid (pictured below), offering Americans a different approach to healthy eating than the USDA food pyramid provided. Through solid research, increased support from experts, and continued education to the public, the Mediterranean diet is regarded today as a powerful weapon against rising rates of heart disease in the U.S.
The biggest health benefit of consuming extra virgin olive oil lies in its powerful antioxidant qualities. Extra virgin olive oil contains polyphenols which act as antioxidants, reducing the oxidative stress throughout your body. Antioxidants also help in promoting and strengthening your immune system making your body more resistant to infections and inflammation.
