Re: trying to cut
Don't think your getting in enough protein for breakfast, maybe have a chicken breast with some mushrooms/tomatoes/pepper/onions and make yourself an omelette. Tasty way of getting in some extra veg as well as I think it is lacking overall.
You could possibly add in some extra quality fats like avocado, oily fish, flaxseed etc as you seem to be eating low fat and low carbs, keep your protein elevated as this will keep you more satiated. You could swop the orange and apple out for berries instead, or at least rotate them around day to day.
Make sure your getting in some variation as well, different sources of carbs, fat and protein and definitely make sure your getting in a lot of veg.
I personally don't think going straight into low carb is always the best way to go, the best way for you to start IMO would be to stick to single ingredient nutrient dense foods, that would naturally drop your calories down after stopping having takeaways etc. Then monitor weight and then drop cals be a sensible 8-10% at a time to get the fat loss moving again. The calories you have started at seem pretty low for a 17 st bloke, just remember if you start off at low calories/low carb etc where are you going to go from there? You will make your diet become extremely difficult when it doesn't necessarily have to be.
Just my 2p:)
