I cant lose weight ?

I have been trying to lose weight eating 1200 calories but I cant lose weight eating that amount I have to eat 500-1000 to lose weight but thats so unhealthy so what can I do and I do do excersize so what else can I do with out being unhealthy???

just eat a good diet with lots of veg and maybe walk more places, Oh and cut out high fat foods its the only thing that works with me, like chocolate, icecream and biscuits!

give up sweets and fried food

NOO you HAVE TO EAT 1200 TO 1400 CALORIES PER AY AND SWAP your 2 SNCKS WITH APPLES OR K-BAR AND DO SOME EXERCISE AND ULL LOSE ABOUT 4 TO 7 KILOS IN LIKE 3 WEEKS

eat apples in the morning because they fill you up more then other stuff so then you dont eat as much during the day
