Those last 10-15lbs.

Not sure if it's been mentioned, but maybe look into carb cycling. I know bodybuilders often use it to get lean before a show, might help you cut those last few pounds. I also know that when I switched to low carb a few weeks ago, the weight started falling off again, after being plateaued for weeks with about 30lbs left.

Eating back your exercise calories? I plateaued when I got to this point, but stopped looking at scale and after a few weeks, I started losing again. Make sure your eating enough, and have your profile set up correct regarding your activity.
Some people will say eat more to weigh less. This, you may need to consider.

Yeah, I have been considering this. I just find it really hard to get those calories back. Feel like I´m eating enough already.

Another thing. Is it important that I eat the calories back the same day I lose them or does like... saving them for extra special days on weekends for example do the same trick?

This is something I struggle with too - but one thing I know is that each day has its own set of calories, and there's really no rollover. It's SO SO bad for you to limit yourself to something outrageous like 500 calories a day for five days just so you can binge on the weekend.

You're supposed to NET a certain number of calories based on your weight and loss goals, so you can eat back exercise calories if you're still netting the proper amount when all is said and done.

Treat each day as its own separate caloric compartment, and make sure you're netting the proper amount of calories (have a minimum of 1200 net calories per day). If you don't, your metabolism will slow way down and trick your body into thinking that you're in a starvation situation, at which point it will conserve every last bit of energy and fat in can, saving up against what it perceives to be lean times, and when your body is saving up like that, it will make you plateau, and anything you eat will go toward weight GAIN until your body can be convinced that you're NOT actually starving and it doesn't NEED to save up every bit of fat because you're NOT actually dying of starvation.

I would add a cup or two of a dark green vegetable - kale, chard, mustard greens - that way you're getting super nutrition without adding a ton of extra calories and maybe your body will be less inclined to save against hard times.

The reason this is hard for me is because in order to lose more than a pound a week, I'd have to dip below the 1200 calorie net-mark, and it's not safe for me to do that, so I'm stuck losing weight excruciatingly slowly, but it's better than plateauing or gaining weight because my body thinks I'm starving!
