I lose more weight on 1800 calories of low-carb foods than on 1800 calories of high-carb foods, so "a calorie is a calorie," seems to be an oversimplification for my body.
There's actually a fair amount of sciece behind why the body (and why some bodies in particular) do treat some calories a little differently than others (it's possible that what you eat can change your metabolism, the "calories out" part of the calories in/calories out equation."
I know when I was younger, it didn't seem to make as much difference as it does now (although I never ate low-carb long enough to notice any possible difference).
I'm not saying that low-carb is for everyone, I'm just saying that for many people, at least, what they eat makes a difference.
An issue where it can also make a difference is in hunger control. I find certain foods and food combinations increase hunger, and others seem to control it. It makes a lot more sense to eat 1800 calories of low-carb/high fiber (on which I am not hungry) than 1800 calories of high carb/low-fiber (on which I am painfully and insanely hungry).
At first, when I started studying my food journals, I thought that low-carb was working better than high-carb only because of hunger control (because I was eating off-plan more because of the extra hunger when I ate high carb). Then I found that even when I strictly stuck to the 1800 calorie limit, I still lost more on low-carb (only some of which can be accounted for by the fact that I retain less water on low-carb).
There are good reasons for pairing some foods together, but there's no magic involved. If you don't have blood sugar issues, and don't find high-carb foods hunger-inducing, you may not need to deal with it at all.
Only experimentation will tell you, if you need to do more than count calories.
As for why you would pair fruit with fat or protein, is (in a nutshell) - it would slow the digestion and impact on blood sugar, which means you will be satisfied longer.
I'm insulin resistant, and if I eat fruit for breakfast, I am STARVING within two hours. This wasn't always true, and when I get thinner and less insulin resistant, I may be able to go back to fruit only for breakfast, but at least for now eating fruit as a meal isn't very practical.
Yes, it can be confusing, but my philosophy is to go with the simplest plan that works. Assuming that you eat a balanced diet (and not complete junk), I would suggest only counting calories (or exchanges, or points or whatever way you want to portion-count/control), and if you're satisfied with your results, that's as far as you have to take it.
