Does virgin coconut oil help with fat loss?

As summer approaches, more and more men dream of having a perfect six pack when they hit the beach on holiday. So what’s going to be their secret weapon? Is it a topical fat loss cream? A new diet perhaps? Or… could virgin coconut oil hold the answer?

Virgin Coconut Oil Weight Loss

Virgin Coconut Oil and Fat Loss

An open pilot study (1) was carried out on 20 obese volunteers (7 males and 13 females) to assess whether the use of virgin coconut oil helped reduce body fat. The body mass index (BMI) of participants ranged between 25 and 30. Volunteers consumed 10ml of virgin coconut oil three times a day (before meals). The weight of the participants was measured one week before and one week after the use of the virgin coconut oil. Body fat percentage, fat mass and fat-free mass were also measured. The safety of the product was checked by assessing the effects to the liver and glucose levels. Scientific measures were used to test the effects of virgin coconut oil on obese individuals such as paired t-tests.

The findings of the study showed that males and females significantly reduced their waist circumference size, with females experiencing a larger reduction than males (3.00 ± 6.03 cm in females versus 2.61 ± 2.17 cm in men). This echoed previous research showing the same results in women (2). In spite of this, the researchers went on to say that only the reduction in waist circumference in the males in the study was regarded as being statistically significant.

The virgin coconut oil assisted fat loss possibly due to the presence of a high ratio of medium chain fatty acids contained within it. Medium chain triglycerides allow for relatively efficient absorption and they do not enter the cholesterol cycle to be deposited in fat depots (3). Other than waist circumference though there were no significant changes in other variables.

Our Comments

Virgin coconut oil is rich in lauric acid which has been shown in previous research (4) to improve serum lipid profiles. This study attempted to establish the benefits of virgin coconut oil on weight reduction and other anthropometric markers by providing the subjects with virgin coconut oil while instructing study subjects to continue their normal daily diet and physical activities to minimise the potential that these two key factors could help to cause a possible weight loss. The fact that the subjects were aware that they were consuming the virgin coconut oil is a study flaw as it was not a blind study. Ideally the study would have compared virgin coconut oil to regular coconut oil with another oil to act as a placebo. The difference between male and female subjects outlined earlier in the results was relatively insignificant. The study authors themselves stated that the results for virgin coconut oil proved modest in both groups.

As conceded by the researchers, it would have been useful for the study to be conducted over a longer period of time to observe how long the results continued over a longer period of time. In addition, the relatively small number of participants makes it difficult to draw firm conclusions.

Future research in this area exploring the effects of virgin coconut oil would ideally do so using larger sample sizes, a placebo controlled group and ensuring there is some measure of dietary control to enable the effects of virgin coconut oil to be isolated more thoroughly. At this point, all we can say is that in obese subjects virgin coconut oil may play a role in possibly helping to reduce abdominal obesity. Its effects on athletes are unknown at this point although the use of this oil in cooking can be recommended given the lack of degradation under heat compared to other vegetable oils.

One thought on “Does virgin coconut oil help with fat loss?

  1. I don’t think that coconut oil is some kind of magic fat loss potion, however I do believe that because it is a fat, and fats are extremely satiating, that it can assist in fat loss. Despite the fact that dietary fats are high in calories, the satiation they provide is extremely beneficial for anyone looking to lose weight – if you’ve ever tried to eat a caloric deficit while consuming large amounts of carbs, such as bread, pasta, rice and potatoes, you may have noticed something – you’re always hungry! However, try eating a diet very high in fat and protein and low in carbohydrates and you may discover something interesting… You’re never hungry!

    See, carbohydrates make your insulin levels go all out of whack which in turn affects your leptin and ghrelin levels which control appetite/hunger. If you eat very few carbs, your insulin levels remain stable which allows you to control your appetite.

    If you don’t believe me, try it!
