Ok, I'm not trying to lose weight at the moment - I stopped when I hit 148 pounds some three or four months ago.  However, I did lose 48 pounds, and so far (even through the holidays and after attempts at 'bulking'!), I haven't gained - my latest weigh in I was 147 pounds.
My advice: breakfast is important, I breakfast like a king.  You've just woken up, your blood sugars are low, its the time to take in those carbs!  As a bonus, if you opt for a high fibre breakfast, the release is going to be slow - its going to keep you going throughout the morning.
Should you eat even if you are not hungry?  Well ... thats up to you, but personally I do, and its working for me.  Because I now exercise lots, and have a healthy, balanced staple diet, I seem to eat tonnes.  Its probably also because I try to graze rather than gorge - that is, I try to have several moderate sized meals/snacks per day instead of one or two big meals.  Sometimes its a struggle to fit in everything - 5 portions of fruit and veg, fibre, water, good fats, and lots of lean protein (strength training) - it doesn't leave much room for treats!  Yes, I personally eat when I don't feel hungry.  In fact, I don't often feel hungry - not in the sense of hunger pangs - cravings yes, but even when I was losing weight, I didn't let myself feel too much 'hunger'.
