Collagen is a type of protein that has been shown to suppress appetite[*], provide fullness compared to other proteins like whey, casein, or soy[*], help retain muscle mass[*] and even help to reduce the appearance of cellulite due to it’s ability to improve skin elasticity and thickness[*]. Refer to this article for more information on the benefits of collagen and the best way to supplement it in your diet.
Milk is limited. There are no long-term risks to eating Mediterranean, says Cohen. But you may be put off if you’re big on eating a lot of milk and rely on it to get all the calcium you need. You’ll get to eat cheese and yogurt, but in smaller amounts. "To get enough calcium in the diet without milk, one would need to eat enough yogurt and cheese, or seek nondairy calcium sources," says Cohen. If needed, drink skim milk. Otherwise, nondairy calcium sources include fortified almond milk, sardines, kale, and tofu made with calcium sulfate. (30)
A study of 39 obese adults placed on a ketogenic very low-calorie diet for 8 weeks found a mean loss of 13% of their starting weight and significant reductions in fat mass, insulin levels, blood pressure, and waist and hip circumferences. Their levels of ghrelin did not increase while they were in ketosis, which contributed to a decreased appetite. However during the 2-week period when they came off the diet, ghrelin levels and urges to eat significantly increased. [11]
There’s been no shortage of coconut oil uses and treatments proven by recent research — it provides not only MCTs (especially abundant levels of lauric acid), but also antibacterial properties, antioxidants, anti-inflammatories and more. The difference between MCT oil and coconut oil is that MCT oil is much more concentrated and contains mostly capric acid and caprylic acid. While coconut oil certainly has MCTs in it, concentrated MCT oil is almost entirely MCTs.
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.

Nutiva Organic MCT Oil is concentrated with the medium-chain triglycerides, capric acid and caprylic acid. Medium-chain triglycerides (MCTs) are easily digested and provide energy, support the metabolism and are burned by the body for energy and fuel. In conjunction with a balanced diet and exercise, consuming MCT Oil can support weight management.
Today’s healthy pasta meals have roots that stretch back to ancient times. Thousands of years ago, people ground wheat, mixed it with water to make a wheat paste, dried it, and then boiled it to go with meals. Today’s consumers welcome pasta to their tables for its versatility and convenience, just as nutrition scientists recognize pasta meals for their place in healthy eating patterns, such as the “gold standard” Mediterranean Diet and the traditional Latin American diet.  Read more
For the sake of science and my book I was trying to emulate the diets of Cretan fishermen from the 1960s, who reportedly had a glass of olive oil for breakfast before a hard day of fishing or goat herding. These high intakes of oil had been suggested as a cause of their remarkable longevity, despite the large amounts of saturated fat they consumed as a result.

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.
The Mediterranean diet wasn’t built as a weight loss plan — in fact, because it wasn’t developed at all, but is a style of eating of a region of people that evolved naturally over centuries, there’s no official way to follow it. But it’s popular because it’s a well-rounded approach to eating that isn’t restrictive. Two of the five Blue Zones — areas where people live longer and have lower rates of disease — are located in Mediterranean cities (Ikaria, Greece and Sardinia, Italy). (2) These places are known for having some of the lowest rates of heart disease and cancer worldwide. (3)

To start, olive oil is very high in compounds called phenols, which are potent antioxidants capable of lowering inflammation and fighting free radical damage. Olive oil is mainly made up of monounsaturated fatty acids, the most important of which is called oleic acid. Oleic acid is known to be extremely heart-healthy in numerous ways, especially when compared to many other refined vegetable oils, trans-fats or hydrogenated fats.
MCTs get their name because of the length of their chemical structure. All types of fatty acids are made up of strings of connected carbon and hydrogen. Fats are categorized by how many carbons they have: short-chain fats (like butyric acid) have fewer than six carbons, medium-chain fats have between six to 12 carbons and long-chain fats (like omega-3s) have between 13–21.
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.
While it’s delicate and not necessarily the best oil for cooking, cold-pressed or expeller-pressed oil hasn’t been refined so it holds all of its natural vitamins, essential fatty acids, antioxidants and other nutrients better. While unrefined oil is separated without high heat, hot water, solvents and left unfiltered, on the flip side some oils are heated to a high degree, which reduces their benefits.

Flynn proved the success of a diet that’s high in healthy fats in 2010 with a study of 44 women over 50 who’d become overweight during breast cancer treatment. Each woman trialled two eight-week diets: Flynn’s olive oil-based diet and a low-fat food plan as recommended by the US National Cancer Institute. Both diets were made up of 1500 calories a day.
