"I'll typically have two chocolate peanut butter fat bombs. They save me. Lately, there’s been a keto cheesecake in the fridge and I’ll sneak a bite, but won’t have a whole piece. I try not to go too hard on the snacks anymore. I’m noticing that laying off the almond flours, coconut flours, and baked sweets has helped me feel better overall. If I want a crunch I’m reaching for the pork cracklings."
One review, published in April 2016 in The American Journal of Medicine, looked at five research trials on overweight and obese people and found that after one year those who followed a Mediterranean diet lost as much as 11 pounds (lbs) more than low-fat eaters. (6) (They lost between 9 and 22 lbs total and kept it off for a year.) But that same study found similar weight loss in other diets, like low-carb diets and the American Diabetes Association diet. The results suggest, the researchers say, that “there is no ideal diet for achieving sustained weight loss in overweight or obese individuals.”
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.
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.
The results in body fat percentage lost was even more striking. The average body mass percentage decreased by 2.9% in the Atkins diet group. In contrast, it decreased by 1.5% in the Ornish diet group, by 1.3% in the Zone diet group, and 1.0% in the LEARN diet group.  This means that subjects in the Atkins diets decreased their average body fat percentage at least twice of any other group- including those eating the low-fat, high carbohydrate Ornish diet.
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.”
These findings are in line with another meta-analysis on 13 randomized controlled trials lasting at least six months comparing low-fat and low-carbohydrate diets. They noted that at six months, subjects who consumed less than 60 grams of carbohydrates per day had an average greater weight-loss of 8.8 lbs. compared to subjects on low-fat diets.  At one year, the difference had fallen to only 2.3 lbs. 
Now that Flynn’s diet has demonstrated acceptance and encouraging results among several different populations, she feels that its potential is even greater than she had first fathomed. The financial accessibility of a plant-based olive oil diet is one of its most significant features, since it is often assumed that such an eating pattern will inherently be pricier than a more traditional standard American diet. Flynn remarks, “When someone says that olive oil is expensive, I point out that they are comparing olive oil pricing to vegetable oil, which I do not think is a fair comparison.” She goes on to note that since animal products often comprise the lion’s share of one’s food budget, purchasing less meat while adding more olive oil typically results in a decrease in overall food costs. This point is especially important for Flynn’s current work with food pantry clients and her future plans to bring the diet to low-income populations to improve their risk factors for chronic diseases.

The ketogenic diet is a diet based on the consumption of predominately fat, giving less emphasis to the other two macronutrients, particularly carbohydrates. While ratios vary depending on the individual and their goals, consumption typically consists of only five to ten percent carbohydrates, fifteen to thirty percent protein and the remainder of the diet is made up of fat.
Flynn says the key to the success of the olive oil diet is to cook your vegetables in olive oil. There are two main reasons for this. The first is that carotenoids – the powerful antioxidants that give orange, yellow and red veg their colour and are also found in abundance in leafy greens – need fat to be absorbed. She also believes the nutrients in cruciferous veg such as broccoli and cabbage are better absorbed with oil, but that’s still yet to be conclusively proven.
