Thanks for the quick replies. I'll take on board to eat more and go back to just losing 1lbs a week. [...]
I am 6ft 0inches and weigh according to gym scales this morning 99.80kg.
I wouldn't worry about losing 2lbs a week, most of the dietary advice suggests that losing 2lbs a week is healthy too.
Likewise, a low-calorie diet is there to lose weight, once you want to maintain weight then you can just steadily increase the number of calories up to say around 2500 for the average man (or perhaps a bit less, closer to 2000 if you're working from home, not out and about much aside from some gym sessions).
I don't see why reducing calories to 1500 for a bit is necessarily a bad thing, have seen stuff by bodybuilders who reduce them down to 1300 even when they want to start cutting fat.
There are some diets that involve far lower calorie intakes - for example, 800 calories even, which they claim can be followed for up to 12 weeks. That would likely cause weight loss at an even greater rate than 2lbs a week.

Though the NHS mentions this is only recommended for obese or severely obese people in particular circumstances + to talk to your GP. As per the other poster, it seems you're at the far end of the overweight range but not quite obese so perhaps not suitable.

I guess the point I'm making though is that cutting to 1500 is fine if you're happy sticking with it as is losing 2lbs a week - that's often mentioned in literature etc.. as a healthy rate to lose weight and 1500 allows for plenty of food, no skipping meals etc.. without having to go hungry.
One thing to do (aside from cutting out the obvious like junk food/snacks and sugary drinks etc..) is perhaps just to cut down a bit on the carbs and eat more veg - you can still end up with a full plate but you've just changed the balance of it a little with a bit less rice/potatoes and more carrots, broccoli, peas etc..
