am i eating correctly?

im 17 years old. im about.. 170cm tall. and i weigh 65-67 kilos

i understand this is a healthy-ish weight and i do not think i am fat.

however i would like to know what changes i should make to my diet. so i can still lose weight (i would like to get down to 60 kilos) and have healthier skin and less cellulite.

here is what i normally eat in a day

breakfast:

2 peices of multigrain toast with processed cheese (with butter on the bread)

a cup of water

recess:

1 handful of banana chips (phillipines)

(once a week i change this to a chicken and cheese toasted sandwhich or a packet of salt and vinegar chips)

lunch:

2 handfuls of unsalted peanuts

or maggi chicken noodles

dinner:

1- 1 1/2 cup of cooked frozen vegetables

two to 3 times a week i have a 600ml brownes Mocha before work

i also aim for 600mls of water a day (not including the glass of water in the morning)

what can i eat to be healthier.

i live on my own and only have 20-30 dollars for shopping each week.

i hate fish and i love chicken

i need to know what excercises i should do to target the fat on my legs (top and lower) and the top of my arms.

id also like to know what the ideal weight is for a 17 year old girl who is of my height.

any tips on losing weight and getting healthy would be aweosme. thank you!
