Dr Mercola states : Traditionally, polyunsaturated oils such as soybean oil have been used for livestock feed because they cause the animals to gain weight. These oils are made up of what is known as long chain fatty acids--the kind of fatty acids that promote weight gain. 4
Coconut oil, on the other hand, is a saturated fat made up primarily of medium chain fatty acids. Also known as medium chain triglycerides (MCTs), medium chain fatty acids are known to increase metabolism and promote weight loss. Coconut oil can also raise basal body temperatures while increasing metabolism. This is good news for people who suffer with low thyroid function. There have been scores of testimonies to this effect.
One happy individual writes:
I am just now jumping on the coconut oil bandwagon (about three weeks now) and I’m really starting to feel GREAT! I have suffered from severe migraines for the past 25 years, the last 15 becoming increasingly severe, coinciding with the addition of soy and the" low-fat mentality" to my diet. Nothing helped! I should be experiencing my pre-menstrual migraine by now and instead I feel like I could climb Mt. Everest! Also I wondered if it decreased the waist to hip ratio because mine has gone from 7.2 all my life to 7 (or something like that). I think I had the sluggish thyroid too, with a low body temperature of between 96 and 96.8. Now it’s starting to climb for the first time in years. Thank you ... Sincerely, V. Potter
Several studies have shown that MCTs promote weight loss. One study showed that rats fed long chain fatty acids (LCTs) stored body fat, while rats fed MCTs reduced body fat and improved insulin sensitivity and glucose tolerance... 5 In March 2003, this same journal published findings that medium-chain triglycerides increase energy expenditure and decrease adiposity in overweight men. The study was conducted with twenty-four healthy, overweight men with body mass indexes between 25 and 31 kg/m. They consumed diets rich in MCT or LCT for 28 days, each in a crossover randomized controlled trial. Those consuming MCTs lost more weight and had more energy than those consuming LCTs (in this case olive oil).
An earlier study in 2002, The Journal of Nutrition came to the same conclusion. They reported that MCTs are more readily oxidized in the liver than LCTs, which leads to more energy and less weight gain. The study concluded that MCTs increase energy expenditure, may result in faster satiety, and facilitate weight control when included in the diet as a replacement for fats containing LCTs.
Scores of people have discovered the benefits of MCTs firsthand. Sharon writes the following to the coconut discussion group:
I have had the same problem with sluggish metabolism and weight gain since having children. Even a no-calorie diet (fast) for 5 days did not work. As soon as I started taking Virgin Coconut Oil the fat began to melt and I have lost 20 pounds. Over the same period of time, my 13- year- old daughter who was very chubby and very worried about it, but could not bring up the self-control to renounce some of her favorite fatty foods, lost about 10 pounds. She now has the perfect figure, to her great joy! Pants she was bulging out of a year ago hang loose on her!
