An article about medium chained fatty-acids:
Effects of medium chain fatty acids (MCFA), myristic acid, and oleic acid on serum lipoproteins in healthy subjects
EH Temme, RP Mensink and G Hornstra
In this study we investigated the effects on lipoproteins of medium chain fatty acids (MCFA) and myristic acid relative to those of oleic acid. Thirty-seven women and 23 men consumed a 3-wk run-in diet enriched in oleic acid followed by a 6-wk test diet rich in MCFA (n = 21), myristic (n = 20), or oleic acid (n = 19). Experimental fats were incorporated into solid foods. Total fat intake was 40 En% fat. The dietary compositions were the same except for 10 En%, which was provided by MCFA, myristic, or oleic acids, respectively. With the myristic acid diet, low density lipoprotein (LDL) cholesterol was 0.37 mmol/L higher compared with the oleic acid diet (P = 0.0064 for difference in changes). The MCFA diet increased LDL cholesterol, though not significantly, with 0.23 mmol/L relative to the oleic acid diet (P = 0.0752). Compared with the oleic acid diet, HDL cholesterol concentrations increased with the myristic acid diet by 0.10 mmol/L (P = 0.0273) but not with the MCFA diet. The MCFA diet slightly elevated triacylglycerol concentrations, but responses did not significantly differ between the diets. The MCFA diet significantly decreased the apoA-I to apoB ratio compared with both other diets (P < 0.02). We conclude that MCFA raise LDL cholesterol concentrations slightly and affect the apoA-I to apoB ratio unfavorably compared with oleic acid. Myristic acid is hypercholesterolemic, although less than predicted earlier, and raises both LDL and HDL cholesterol concentrations compared with oleic acid. 
Another interesting article:
Influence of stearic acid on cholesterol metabolism relative to other long-chain fatty acids
SM Grundy

Stearic acid is a long-chain saturated fatty acid. However, in contrast with other saturated fatty acids, stearic acid apparently does not raise serum cholesterol concentrations. Studies carried out three decades ago provided strong suggestive evidence that this was the case. More recent investigations that specifically compared stearic acid with other fatty acids in human studies have confirmed that stearic acid is not hypercholesterolemic. Stearic acid was shown not to raise low- density-lipoprotein cholesterol relative to oleic acid, which is known to be neutral in its effects on cholesterol concentrations. In contrast, palmitic acid, another long-chain saturated fatty acid, definitely raises cholesterol concentrations. For this reason, fats rich in stearic acid might be used in place of those high in palmitic acid in cholesterol-lowering diets.

Interesting article, but keep in mind, most scientists don’t seem to consider lauric acid a MCT as far as I can tell. Wikipedia does, as do many websites with obvious bias, but pretty much all actual research articles that I found identify LCT as 12-18c.

Medium chain fatty acids (MCFA) are readily oxidized in the liver. Animal and human studies have shown that the fast rate of oxidation of MCFA leads to greater energy expenditure (EE). Most animal studies have also demonstrated that the greater EE with MCFA relative to long-chain fatty acids (LCFA) results in less body weight gain and decreased size of fat depots after several months of consumption. Furthermore, both animal and human trials suggest a greater satiating effect of medium-chain triglycerides (MCT) compared with long-chain triglycerides (LCT). The aim of this review is to evaluate existing data describing the effects of MCT on EE and satiety and determine their potential efficacy as agents in the treatment of human obesity. Animal studies are summarized and human trials more systematically evaluated because the primary focus of this article is to examine the effects of MCT on human energy metabolism and satiety. Hormones including cholescytokinin, peptide YY, gastric inhibitory peptide, neurotensin and pancreatic polypeptide have been proposed to be involved in the mechanism by which MCT may induce satiety; however, the exact mechanisms have not been established. From the literature reviewed, we conclude that MCT increase energy expenditure, may result in faster satiety and facilitate weight control when included in the diet as a replacement for fats containing LCT.
From what I found out VCO seems to be beneficial but that isn't because of the Trigliceride itself but because of the polyphenols and phytosterols it contains....so I'll be looking into getting those elsewhere. All research I can find says that Lauric acid in itself is moderately bad for you, but there are enough anti-oxidants in VCO to offset this negative impact on btl, I soooo wish I could find something that talked about inflammation tho. Although anti-oxidant levels seem to say there should be none, all studies that showed cvd risk, showed vco still upped the risk, although not nearly as much as palm oil (don't believe anything about palm oil being good for you please, I read study after study, there were dozens for every one I found on vco, that said it really ups your risk, of cvd), this seems to point to there being something that raises it, which inflammation is the only thing I could think of. Dunno, I'm currently waaay to busy to do the kind of research I'd normally do.

You are crash dieting. There are so many studies contradicting all of that btw.

^^Yep, I know. Basically what I'm doing is a raw diet Monday-Friday with adequate calories (according to a Dr and a nutritionist that I saw years ago before doing this the first time) and lots of high quality complementary veggie proteins and daily avocado and olives for healthy fat. For some reason the raw diet threads never gets peoples panties in a wad though. Next time I do this for a couple of weeks, I think I'll just call it that and avoid all the attacks. I don't get it, it's okay for a meat eater to go raw and eat this way or even to fast or do the master cleanse but because I'm already a veggie people seem to take it as a personal attack when I do it? Confuzzling
I really don't get why it seems to upset you personally so much though, it's not like I'm telling you what you need to be eating or trying to get anyone else to eat like me. You can eat all the animal products you want and I guarantee you that I'll never make a negative comment about it. Not my biz. ;)
I do know that when I eat this way for a couple of weeks, my metabolism seems revved up, not slowed down, my hair, skin and nails look fabulous and I feel incredible. If I felt ran down and sluggish, I wouldn't do it every few years, regardless of it's effectiveness for weight loss. I do it more as a jump start if I've slipped from my healthy eating and working our regimine and being in school and pulling straight A's this past semester while being a mom and dealing with my crazy bitch mother....well I definitely slipped out of my good habits a bit. ;)
I don't know...I'm still thinking there are other diet changes you can make that will help you lose weight faster than an all fruit/veggie diet. Check out J.D's thread on her daily foods - eating like that will help you lose weight faster
May or may not be faster, but retains lean bodymass (essential to your metabolism, health, and looks..), is better for you, will maintain the fat loss (vs weight loss people!!!!!!) over time, etc. etc. ;)

I'm not upset. It's not my body.

when i was really slim before i moved to the south, i went on a diet where the only things i ate were smoked salmon, kale, avocados, and almonds. and i was a gym rat... i looked amazing.
now i have gone back on a diet that is similar to that one, but i am a little less strict. and sice it is summer , i am no longer a gym rat. i have been biking a lot though... ive been biking an average of like 35 miles a day... this week im going to push it up to 50 a day.
but it works... i have lost my texas layer of fat. now i need to lose my new orleans layer of fat to be back where i was in december.
how far are you from school? have you considered biking too and from school? also, working out 2x a day is good... because for a few hours after you work out your metabolism goes up. so if you work out twice you get the metabolism boost 2x a day.
also when running, try doing interval training. this will jack up your metabolism more than long distance at a slow pace.

Oh crap! I forgot to add this. I found one studies that said that saity is greatest with mct. They stave off hunger even more effectively than lct according to some research, which was a bit of a suprise to the researchers. So, for weight loss and maintenance, they would probably be very helpful.
There was also a couple of studies that showed that stearic acid (in animal product, cocoa and shea butter) is much less damaging to the cardiovascular system (and possibly beneficial at preventing some other diseases) than are other sat-fats. Didn't really take the time to read up on this since I was looking up vco and wanted to get outside to do fireworks with the kiddos, but if anyone else is interested enough to research it, I'd love to hear what you find out.

Oh, I'm hitting the gym hard! No reason to lose muscle instead of fat! I run every morning and then hit the gym in the afternoon for weights. (I do the interval thing too, not on purpose, just cause I'm shooting for a long, hard run like I used to, but I'm not in shape enough, so I go all out for a few minutes then am barely above a jog for a few. lol) Then I push the kiddos around the community here on and off most of the day and then I'm on my stairmaster for a light bedtime workout. When I do this right I tend to not really lose any weight, but I just loose that little layer of fat that drives me crazy!
I WISH I could bike to school, but it's a narrow mountain road, I'd be killed, eek!! It takes an hour by car too, so I dunno how long it would take on my bike. I am going to be on the campus with the gym, though! Yayy!!! Hopefully gym access, plus being away from my crazy mom will ensure I don't get all squishy next semester! :)

I do lose fat when I diet this way. That's why I love it! I can eat whenever I'm hungry if I cut out grains and added fats Mon-Fri and this enables me to get enough cals to feel good and continue working out. While if I just shave a few hundred cals of my regular diet I feel and look like crap and end up skinny/flabby, which I HATE. Seeing thin girls with no muscle tone with meat just hanging off their bones gives me willies. Hell, I'd rather be fat than look like that. ;)
I do appreciate that this may not work for everyone, but it works well for my body. I've done several times through the years and I always come out looking and feeling fabulous! If I ate like most people I see, I'd stay in the hospital constantly from severe kidney inflammation that closes off the upper pole of my left kidney and requires surgery. Sucky suckiness :(
I do lose fat when I diet this way.
And what objective measure are you using to determine that? What's your current BF% and what was it when you started?
If you are not using DEXA (expensive but very accurate), underwater weighing (PITA, but accurate), 3-7 spot caliper testing (as long as the person doing really knows what they are doing, a good method) or an Accumeasure or SlimGuide (cheap, easy to use, and quite accurate) then you have no real objective way to know what % lost was fat, LBM, water, etc. Diets as you mention are often a large % as water, some fat, and muscle.

^^While I don't know with 100% certainty, when I stay approximately the same weight (or at times I've even gained a few lbs) while losing inches all over, it seems to point to building muscle and losing fat. Oh and when I did it before my trainer did do caliper testing periodically, but I don't really know if she really knew what she was doing or not. I know she was basically completely against being a veggie and was very suprised that I seem to thrive eating this way. But as I've said before, I'm not really cutting my calories that significantly if at all, I'm just cleaning up my diet and avoiding dairy/grains Monday through Friday. I find that this strategy enables me to eat enough to avoid hunger while still shaping up super fast....and sorry, but I just can't, can't, can't eat dead animals. I srsly don't have it in me.
Oh, back in college I ate this way for years, with the addition of a yogurt a few times a week and a couple of beers on the weekends of course (it was college after all! lolerz.) Over a few years of working out pretty hard I went from like 105lbs to right over 120....I'm ashamed to even type that number.. lol, but I stayed the same size! It was craaaazy!!

Hey there,
I think that if you feel good while on this diet and you get the results you want, then there is no problem with it. Everyone is different and our bodies react differently to foods. If you have tried it before and liked it, then go for it! Don't feel that you need to justify to others your reasons or why it is right for you!
In the past I have gone completely raw at different times and am slowly getting into it again, hopefully for more then a few months. The natural high/effects on my body are amazing, digestion, my skin, regularity, i sleep better, have more energy, and think more clearly. While i am eating raw I get the bulk of my calories from fruit so in my personal experience if enough calories are consumed and you have the right amount of fat for YOUR body then this is a great way to eat and I wish you all the best in your goals!
