in a nutshell, carbs (specially easily digested carbs, also known as High GI carb) are converted to glucose (blood sugar) in a very rapid manner, the higher the GI the faster this occurs. When the glucose levels increase, the body reacts by secreting insulin. Insuline is a "storage hormone", which means, in plain terms, it's a sort of "shuttle" for nutrients into your cells.
You use this "shuttle" service when you do the whey-carb combination (for example, Post workpout), but yep, you guessed it, if you take carbs and fats, the fat uses the same shuttle.
I came across a funny article, check it out: http://home.howstuffworks.com/fat-cell1.htm
on page 3 they explain the insuline role in this

I think this question should be rephrased to read, the science behind simple carbs and fats. Classifying carbs as evil is wrong. Carbs can very well be eaten with fat. It is the type of carb, the timing, etc. that is the crux of the matter.
A phrase like carbs and fat cannot be eaten together is a blanket statement that cannot be made. From the article itself stated in the above post.....
The conversion of carbohydrates or protein into fat is 10 times less efficient than simply storing fat in a fat cell, but the body can do it. If you have 100 extra calories in fat (about 11 grams) floating in your bloodstream, fat cells can store it using only 2.5 calories of energy. On the other hand, if you have 100 extra calories in glucose (about 25 grams) floating in your bloodstream, it takes 23 calories of energy to convert the glucose into fat and then store it. Given a choice, a fat cell will grab the fat and store it rather than the carbohydrates because fat is so much easier to store.
So, it is not the carbohydrates per sey. Fat storage does not require iinsulin from carbohydrates to be stored, it can in fact do a good job on its own.
Somehow this food partitioning thing got started, there is some mistaken notion that this is the way to eat and lose weight. While this is true, it is not due to food partitioning.
Here is part of a post I made earlier, for laziness not wanting to retype it.....As far as the food partitioning, I already stated my stance on this, and can back it up. If you look at the references cited in these arguments, every study suggesting that macro composition matters is looking at different protein intakes, with higher being better. Duh! People on high-protein always tend to eat less. So do people who reduce carbs or switch to lower gi foods. Early low-fat studies found the same: take out a calorically dense food and people eat less. It is easy to interpret some metabolic advantage but what is actually going on is that dietary changes make people eat less automatically(i.e...not mixing carbs and fats).

I am still unclear of when I can use EFAs and MCT oil. For example if I am to eat a chicken breast and brown rice can I take EFAs with this meal? If not when can I take them.
Post-workout I drink half of and ABB Carb Force drink which is about 50g of carbs plus I take and rALA, Omega 369 and CLA. I also take in 50g of isolate protein. Is it bad to do this?
I am trying to diet down and I have dropped slowly from 220 lbs to 190lbs. Not sure what my bodyfat was to start, I would estimate it around 23-25% and now I am 17%.
Right now my meals are sitting at 40g protein and 45g carbs 5 times a day plus my PWO shake and carbs. Not sure what my fat intake is besides the EFAs which are a total of about 25-30g per day. I am using mostly lean ground beef and chicken for my protein. My carbs are coming from long-grain brown rice and oatmeal.

Let's put it this way.
Slow carbs (low GI carbs) and EFAS: GO (at least in my experience, besides, about everybody here takes flax and oats together)
Fast Carbs + Fat (ANY fat, remember EFAs are still fats, good ones, but fat still): Avoid them if you can
Anything with trans-fats, saturated, hydrogenated... run for cover

MCT medium chain triglycerides. These in fact can be viewed somewhat as digestible like carbs, not their long chain bretheren. MCT oil is metabolized easily, thus a good energy source. Pre workout is a great time ot use it.
EFA's on the other hand can be used throughout the day. The idea at the end of the day, is to fit them in your calorie needs. Even if a food is good for you, like EFA's are wonderful, when all is said and done, if you go over your calories for an extended period of time, guess what, you will gain weight!
Wanting to diet, you simply need to create a caloric deficit. That is take in less calories than maintenance. So, you need to factor EFA's in your diet. Subbing good fats for bad carbs is a wonderful way to go. As you reduce carbs, you can increase fats. As you reduce your carbs, you will need to pick up some calories elsewhere. This is where adding fats and upping your protein will work well. In the end, you can end up with a 50/30/20 p/f/c macro ratio for example. While still having a caloric deficit.
