Coconut Oil: A Healthy Choice

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

How MCTs Promote Weight Loss

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! 

Coconut Oil and Oxidative Stress

One of the reasons the long chain fatty acids in vegetable oils are so damaging to the thyroid is that they oxidize quickly and become rancid. Food manufacturers know about this propensity towards rancidity and, therefore, highly refine their vegetable oils. Considerable research has shown that trans fatty acids, present when vegetable oils are highly refined (hydrogenated or partially hydrogenated), are especially damaging to cell tissue and can have a negative affect on the thyroid as well as health in general. Because the longer chain fatty acids are deposited in cells more often as rancid and oxidizing fat, impairment of the conversion of thyroid hormone T4 to T3 occurs, which is symptomatic of hypothyroidism. To create the enzymes needed to convert fats to energy, T4 must be converted to T3. 

Dr. Ray Peat says: 

When the oils are stored in our tissues, they are much warmer, and more directly exposed to oxygen than they would be in the seeds, and so their tendency to oxidize is very great. These oxidative processes can damage enzymes and other parts of cells, and especially their ability to produce energy. The enzymes which break down proteins are inhibited by unsaturated fats; these enzymes are needed not only for digestion, but also for production of thyroid hormones, clot removal, immunity, and the general adaptability of cells. The risks of abnormal blood clotting, inflammation, immune deficiency, shock, aging, obesity, and cancer are increased. Thyroid [hormones] and progesterone are decreased. 

Since the unsaturated oils block protein digestion in the stomach, we can be malnourished even while "eating well." There are many changes in hormones caused by unsaturated fats. Their best understood effect is their interference with the function of the thyroid gland. Unsaturated oils block thyroid hormone secretion, its movement in the circulatory system, and the response of tissues to the hormone. Coconut oil is unique in its ability to prevent weight-gain or cure obesity, by stimulating metabolism. It is quickly metabolized, and functions in some ways as an antioxidant.

Because coconut oil is saturated and very stable (unrefined coconut oil has a shelf life of about three to five years at room temperature), the body is not burdened with oxidative stress as it is with the vegetable oils. Coconut oil does not require the enzyme stress that vegetable oils do, preventing T4 to T3 hormone conversion, not only because it is a stable oil, but also because it is processed differently in the body and does not need to be broken down by enzyme dependent processes as do long chain fatty acids. 

Also, since the liver is the main place where damage occurs from oxidized and rancid oils that cause cell membrane damage, and since the liver is where much of the conversion of T4 to T3 takes place, eliminating long chain fatty acids from the diet and replacing them with medium chain fatty acids found in coconut oil can, in time, help in rebuilding cell membranes and increasing enzyme production that will assist in promoting the conversion of T4 to T3 hormones. 

More research in this area is necessary. In the meantime, those switching from polyunsaturated oils to coconut oil are reporting many positive results. For example, Donna has experienced encouraging improvements in her thyroid health. She writes:

I've been on coconut oil since September, 2002 and, although, that doesn't seem like long, it has changed my life and the lives of my family and friends. My weight actually went UP when I started on coconut oil but I felt so GREAT! Being hypothyroid, I was on Synthroid and Cytomel and had been for years, but with inconsistent results and feeling worse. Other changes besides the addition of coconut oil were the complete removal of soy (and that is a major challenge in itself!), all trans fatty acids, no refined sugar, and organ cleanses seasonally.

My thyroid meds were discontinued with my doctor's knowledge as I was getting too energetic and having trouble sleeping! [Imagine], from being a "sleepaholic" couch potato that was cold! My weight stayed steady until the last three weeks and it has now started the downward move. My goal was health and just believed the weight would come off when I found the right diet and exercise routine that my life was comfortable with. I've tried removing the coconut oil but my energy drops and I don't feel as good. Donna

Lori writes:

I have been taking VCO [virgin coconut oil] for about two to three months. Before the VCO, my thyroid results were borderline low. After two months of one tablespoon a day[of coconut oil], they are now mid-normal range. They have never been this high. I do NOT take any thyroid. ALSO my cholesterol is still the same as well as my LDL. BUT my HDL [the good cholesterol] rose 10 whole points from 43 to 53! This is a miracle for me. Lori

Coconut oil has helped scores of women who are menopausal. Several women who were post-menopausal suddenly began having their menstrual cycles start again, which is evidence that coconut oil does indeed increases hormone production. 

Another happy lady writes:

I have experienced the same problems as you. Body temperature not going above 97 degrees, cold hands and feet, can't lose weight, fatigued, slow heart rate, can't sleep some nights, dry skin, etc. ... My doctor did the same test and it came back normal. I am also 46 and peri-menopausal. My Naturopath symptomatically diagnosed me with hypothyroidism. She explained the blood tests currently used by allopathic medicine are not sensitive enough. I started on the [ coconut] oil 5 weeks ago.

In the first week I noticed my body temperature had risen and my resting heart rate had gone from 49 to 88 beats per minute. This has since settled to 66. My energy is now really high and I am slowly losing the weight--three pounds in the past five weeks. I also had been taking flaxseed oil and gamma linoleic acid oil but have stopped eating every other oil but what Raymond Peat recommends, which is coconut oil, olive oil and butter (obviously using the last two very sparingly). I take 3 tablespoons of coconut oil daily. I have discussed this with my Naturopath and have given her all the written material on it. She's very open to knowing more about it. Cindy
