Most fundamentally, olive oil, like all oils and fats, are a concentrated source of calories. With over 4,000 calories per pound, olive oil is far more calorie dense than even pure refined sugar, which has 1,725 calories per pound. Because of its extremely high calorie density, adding olive oil to any food or meal will dramatically increase its calorie density.
One of the “hearty healthy” effects of olive oil, argues the olive oil industry, is that it raises levels of HDL good cholesterol. But higher HDL levels do not always mean better arteries. Remember the study on monkeys discussed at the beginning of this article? The higher HDL levels of the monkeys consuming a diet rich in monounsaturated fat did not prevent them from developing plaque–ridden, diseased arteries.

Research supports the health benefits of a Mediterranean-style eating pattern that includes several different foods. It is the combination of these foods that appear protective against disease, as the benefit is not as strong when looking at single foods or nutrients included in the Mediterranean diet. [12] Therefore it is important to not simply add olive oil or nuts to one’s current diet but to adopt the plan in its entirety.
Get a good night sleep: During menopause, many women find their quality of sleep sharply deteriorates, often because of hot flashes and night sweats. Drs. Fung and Hallberg really recommend that women in weight loss plateaus aim to improve their sleep. A good night sleep reduces stress and cortisol, the stress hormone that when raised hangs onto abdominal fat.

I lost most of my weight on a high protein, low carb diet prescribed by my surgeon, but I’ve recently started the Deeper State Keto program which is much higher fat. I’ve cut out the protein bars and shakes and have so much energy. I feel like I could do cartwheels at all times. It’s not like I felt bad before. I wasn’t sleepy, lethargic, or sluggish. Now, I’m alert, bright and energized all the time."


When it comes to eating a healthy diet, olive oil is your best friend. It tastes delicious, it's full of healthy, good-for-your-heart fats, and it might even help fight off dangerous belly bugs. But there’s another way this golden health elixir can make your life better—and you don't even need to eat it. Simply smelling olive oil may help you lose weight, according to a recent study in the American Journal of Nutrition.
Cancer — While we can’t say that being obese or overweight causes cancer, consistent evidence indicates that higher levels of body fat are associated with increased risks for certain types of cancer, including breast cancer, kidney cancer, colorectal cancer, and endometrial cancer. In fact, overweight women are two to four times more likely to develop endometrial cancer (a type of cancer that begins in the uterus).
In Britain and the US, people consume on average around 1 litre of olive oil per person per year, but isn’t much compared to the Greeks, Italians and Spanish who all consume more 13 litres per person. Olive oil, with its high calories and mixed saturated and unsaturated fats, was once assumed by many doctors to be dreadfully unhealthy. But health surveys of European populations kept finding that southern Europeans lived longer and had less heart disease despite higher fat intakes. It turns out olive oil was the likely reason.
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.)
Because of the data, the research team stated that “the low-carbohydrate diet was more effective for weight loss and cardiovascular risk factor reduction than the low-fat diet. Restricting carbohydrates may be an option for persons seeking to lose weight and reduce cardiovascular risk factors.” [18] They also noted that “no serious adverse events were reported during the course of the study.” [18] Thus, the ketogenic diet might be a both a safe and effective weight-loss plan for you.
Is pasta good or bad for you? Pasta is a staple food in many diets. It is quick, inexpensive, and filling. However, some types of pasta may be unhealthful and add too many calories to a person's diet without providing much nutrition. In this article, learn which types of pasta are good for you, as well as how to create a healthful pasta-based meal. Read now
Caution: Palm oil is a controversial source of MCTs, not because it’s bad for your body, but because there are major issues involved in the process of procuring this oil. These include deforestation, loss of wildlife diversity and unethical treatment of workers. That’s why I only recommend RSPO-certified palm oil, which comes from producers who prioritize sustainability practices.
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.

Here's what I learned about the keto diet: You essentially swap a high-carb diet, which most Americans tend to eat, for a diet that's very high in fat (the healthy kinds), moderate in protein, and very low in carbohydrates. The idea is that you change the source from which your body gets its energy (and burns calories) from glucose (from carbohydrates) to ketones (from fat). This shift doesn't happen after one bulletproof coffee, though. It usually takes a few days of eating this way for your body to reach ketosis-where it's looking to fat as its first source of fuel. Once there, though, your body "will be burning fat all the time," says Dr. Axe. "It doesn't matter if you're working out or sleeping, or what you're doing, your body continues to burn fat in ketosis."
Research shows that greater adherence to the traditional Mediterranean diet, including plenty of monounsaturated fats and omega-3 foods, is associated with a significant reduction in all-cause mortality, especially heart disease. A striking protective effect of a Mediterranean diet rich in alpha-linolenic acid (ALA) from olive oil has been shown in many studies, with some finding that a Mediterranean-style diet can decrease the risk of cardiac death by 30 percent and sudden cardiac death by 45 percent.

Butter vs. margarine: Which is most healthful? Many people are unsure whether butter or margarine is better for their health. While butter is a dairy product containing saturated fats, margarine consists of plant-based oils and often contains trans fats. We provide the nutritional breakdowns for both products and explain how to make the most healthful choice. Read now
Olive oil contains biophenols, which suppress the oxidization of LDL (or “bad cholesterol”) which has been shown to play a role in the development of cardiovascular disease. High levels of LDL in the blood amplify oxidative stress which hardens the arterial walls (called atherosclerosis). The biophenols in olives reduce blood pressure, therefore reducing the development of arterial plaque as well.
Eliminating several food groups and the potential for unpleasant symptoms may make compliance difficult. An emphasis on foods high in saturated fat also counters recommendations from the Dietary Guidelines for Americans and the American Heart Association and may have adverse effects on blood LDL cholesterol. However, it is possible to modify the diet to emphasize foods low in saturated fat such as olive oil, avocado, nuts, seeds, and fatty fish.
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.
Day 13: I have a love-hate relationship with this intermittent fasting thing. I think it's "working," and by that I mean I'm losing some weight. (Plus, improved body composition and definition can come with weight loss.) When I ask Dr. Axe if I should attribute my success to keto or IF, he says both. "I would say 80/20 it's more strongly in the favor of keto, but intermittent fasting does help as well," he says. The fat-burning capabilities of keto have more strength behind it when it comes to weight loss, specifically, he adds, but the intermittent fasting can be great for digestion and just feeling good.

Fat is a macronutrient with many benefits, one of which is the absorption of fat-soluble vitamins A, D, E and K. It is also a building block of every cell membrane in the body. It provides energy, slows the absorption of other nutrients (so you feel full longer after a meal) and is required for healthy liver function. Plus, let’s face it, fat makes food taste better.
In 1993 Oldways created the Mediterranean Diet Pyramid – in partnership with the Harvard School of Public Health and the WHO – as a healthier alternative to the USDA’s original food pyramid. Today, the Mediterranean Diet is more popular than ever, with new research every month documenting its benefits, and chefs and home cooks alike embracing Mediterranean ingredients and flavors. Starting at the base of the pyramid, you’ll find:

Maybe you don’t want to choose olive oil over, say, butter or marbled steak for the rest of your life. Not to worry. “You don’t have to give up favorite foods forever,” Palinski-Wade promises. “As you use my plan and lose weight, your body chemistry shifts. You’ll be able to indulge from time to time without adding belly fat.” And if you’re looking to get a smaller waist as quickly as possible, “You won’t find a better jumpstart. This is perfect for the impatient dieter.”
