Easy convenient foods you could eat: Pork pies, scotch eggs, sausage rolls. If you fancy some cooking you could oven cook some burgers and make some cheese burgers up. I buy lean burgers from the butcher, cook them for 20 mins and throw them into some big wholemeal baps with 2 cheese slices and jalapeno relish. Very quick and tasty! Hard boiled egg mashed with mayonaise (maybe a bit of cress if you fancy it) slung into a wholemeal bap is also another quick and easy meal.

It applies more to a well rounded diet. If your body is using more energy than you give it, you have to lose weight on a basic level.
