Do I need to eat more? Or am I eating badly?

I looked at your diary and it seems that you're doing okay on your macros. If your weight loss is stalled and you are truly logging *everything* you eat then no, you don't need to eat more. Your maintenance needs have adjusted to your current intake. You might want to exercise more to create a larger deficit... or any deficit at all. Focus on strength training, especially this close to your goal. perhaps drink a little more water. The last few kg will take the longest, but strength training will help improve your look even if the scale doesn't drop as much or as fast as you'd like.

I personally believe you should eat more considering you are working out. If you search MFP for "1200 plateau" you should find plenty of threads with people going through the exact same thing. I went through it myself and slowly upped to 1650 calories. The weight fell off again. Also as the previous user suggested, add some weights to your workouts.

The last few pounds is always the hardest and slowest. You should be aiming for no more than .5 lb / week loss at this point. From your diary it looks like you aren't weighing things. There are lots of "generic' entries. Those are the places where your small deficit can all but disappear. A scale would help immensely.

In terms of your calorie intake it's hard to say, I can see that you are not eating back any of your calories which is normally recommended if you are following the MFP plan as designed but as far as how much you should eat it will depend on your height, weight and age which you did not provide.
