There has also been increased interest in the diet’s effects on aging and cognitive function. [9-11] Cell damage through stress and inflammation that can lead to age-related diseases has been linked to a specific part of DNA called telomeres. These structures naturally shorten with age, and their length size can predict life expectancy and the risk of developing age-related diseases. Telomeres with long lengths are considered protective against chronic diseases and earlier death, whereas short lengths increase risk. Antioxidants can help combat cell stress and preserve telomere length, such as by eating foods that contain antioxidants nutrients like fruits, vegetables, nuts, and whole grains. These foods are found in healthy eating patterns like the Mediterranean diet.  This was demonstrated in a large cohort of 4676 healthy middle-aged women from the Nurses’ Health Study where participants who more closely followed the Mediterranean diet were found to have longer telomere length. 
Weight loss in obese or overweight individuals. Research shows that taking MCTs can decrease body weight, body fat, and waist and hip circumference by a small amount. At least 4 weeks of use is likely needed to see any benefit. Men, people of Asian descent, and people with the highest amount of body fat before treatment seem to benefit the most. However, for most people any benefit is only slight and might not be clinically meaningful.
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.
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.
