    Arrow MCT's vs Olive Oil for Fat Loss (Study)

    Thought this was interesting...(and maybe I'm behind on this):

    Weight-loss diet that includes consumption of medium-chain triacylglycerol oil leads to a greater rate of weight and fat mass loss than does olive oil1,2,3
    Marie-Pierre St-Onge and Aubrey Bosarge

    1 From the College of Physicians and Surgeons, Columbia University and New York Obesity Research Center, St Luke's/Roosevelt Hospital, New York, NY (M-PS-O), and the Department of Nutrition Sciences, University of Alabama at Birmingham, Birmingham, AL (M-PS-O and AB)

    Background:Clinical studies have shown that consumption of medium-chain triacylglycerols (MCTs) leads to greater energy expenditure than does consumption of long-chain triacylglycerols. Such studies suggest that MCT consumption may be useful for weight management.

    Objective:We aimed to determine whether consumption of MCT oil improves body weight and fat loss compared with olive oil when consumed as part of a weight-loss program.

    Design:Forty-nine overweight men and women, aged 1950 y, consumed either 1824 g/d of MCT oil or olive oil as part of a weight-loss program for 16 wk. Subjects received weekly group weight-loss counseling. Body weight and waist circumference were measured weekly. Adipose tissue distribution was assessed at baseline and at the endpoint by use of dual-energy X-ray absorptiometry and computed tomography.

    Results:Thirty-one subjects completed the study (body mass index: 29.8 0.4, in kg/m2). MCT oil consumption resulted in lower endpoint body weight than did olive oil (1.67 0.67 kg, unadjusted P = 0.013). There was a trend toward greater loss of fat mass (P = 0.071) and trunk fat mass (P = 0.10) with MCT consumption than with olive oil. Endpoint trunk fat mass, total fat mass, and intraabdominal adipose tissue were all lower with MCT consumption than with olive oil consumption (all unadjusted P values < 0.05).

    Conclusions:Consumption of MCT oil as part of a weight-loss plan improves weight loss compared with olive oil and can thus be successfully included in a weight-loss diet. Small changes in the quality of fat intake can therefore be useful to enhance weight loss.
    And for more info...

    MCT stands for medium chain triglycerides. Most naturally occurring fats are triglycerides - tri meaning that each molecule have three carbon chains. In the medium chain triglycerides each chain has 6 - 12 carbon atoms, and for the medically refined grades of MCT oil each chain has 8 - 10 carbon atoms. MCT oils occur naturally, and the most abundant source is coconut oil. Most MCT oil is refined from coconut oil.

    I saw a post by Dr Crisler that said something about mct's and increasing estrogen.....but it may have been from a soy MCT product? I'll have to search around for that...

    Cocounut oil clearly makes more sense for a male rather then any soy product.

    Yeah I at first just started using it because I got so tired of using nothing but olive oil in my shakes... (shudders).

    I use it only sparingly though really, its full of saturated fat and according to the good doc only about 20% of my fat intake on my cyclic carb diet should be from saturated fat, soo the rest is poly/monounsaturated.

    I use coconut oil frequently in place of any of the other oils i can. use it in pancakes in place of corn oil, use it for pan frying eggs + shrimp + fish, basically whenever I can I do

    Olive oils and others are great for adding in easy, quick calories, 2 scoops of protein and 3 and a half tablespoons of oil (olive, coconut, etc) is like 620 calories right there. Make it and down it, takes 30 seconds to make and 30 seconds to down

    Well i've also been on the routine Dinoiii set out in the thread I started about routines for hargainers and I'm up 1-2lb. I'm guessing its a bit of both but its just a great way to get some extra calories in!

    As part of the weight-loss program, the subjects were counseled to reduce their caloric intakes to 1500 kcal/d for women and 1800 kcal/d for men.


    Looks like both are leveling off. So, what is the effect on persons who consume a higher than average amount of unsaturated fats? Probably little.

    One person in the MCT group who dropped out for food complaints did so because she said the oil made her sick.

    Heh, thanks for posting it I hadn't seen it yet.

    Weight loss might continue if there is some appetite suppression:

    In our previous study, we found that women burn {approx}45 kcal/d more when consuming medium-chain saturated fats than when consuming long-chain saturated fats (12). In addition, studies have found that subjects consume an average of 62.5 kcal/d less when meals contain MCT instead of LCT (19). The addition of an enhanced thermic effect of food and reduced food intake would result in a lower caloric retention of 107.5 kcal/d. This lower caloric retention, if maintained over a 16-wk period, would lead to an additional loss of 1.55 kg body wt with MCT consumption than with LCT. Our finding of a 1.7-kg difference in weight loss thus agrees with our earlier hypothesis (19).
    Maybe subjects simply became more lax as time went on.

    Also the groups were fairly small because of a high dropout rate: (MCT, n = 16; olive oil, n = 15). Only 3 total male subjects.

    Here are more numbers for weights (kg) weeks 12-16 for each group:

    MCT
    12 77.2 0.46
    16 77.2 0.462

    Olive Oil
    12 78.3 0.47
    16 78.9 0.47
    ^^Increase in weight.

    These numbers are more interesting:

    Change in body compartment MCT oil (n = 16) Olive oil (n = 15)
    Total fat mass (%) –1.46 0.452 –0.58 0.46
    Total fat mass (kg) –2.23 0.572,3 –0.69 0.58
    Trunk fat mass (%) –1.23 0.73 –0.49 0.75
    Trunk fat mass (kg) –1.20 0.352 –0.34 0.36
    Intraabdominal adipose tissue (cm2) –8.85 3.92 –1.32 4.194
    Subcutaneous abdominal adipose tissue (cm2) –24.76 9.37 –11.29 10.024

    I wonder what effect the counseling has in all of this

    I'm just very skeptical of these type of studies on how applicable they would be to persons who exercise or are familiar with nutrition basics. 1.7kg fat difference between MCT and Olive Oil after 16 weeks is moderately significant I guess when considering similar research.

    I was thinking after your initial post that the subjects did just become more lax overtime...lost excitement in the plan, or whatever.

    But your right over 16 weeks the results are not significant. Your point in bold is very applicable though...I guess thats why I am always on the lookout for studies involving "well-trained athletes/males".

    Thank you for your input though.
