Strangely enough im the same age and roughly the same weight as you, lol. I've always been a
fat kid because I couldnt say no to fatty food, until in June I became 90kg. Now i've learnt to say no to; coke, cheese, chocolate, sugary stuff etc.. I also joined the
gym in June and did
cardio/weights, and lost 5kg in a month, now 85kg!
Sorry to burst your bubble, but theres no "fast" way to lose
fat/weight, and you cant target an area,
fat is lost all over. Its like learning a language, it takes time. With the right
diet, and hard work, it should take a year or two!
My advice is DONT cut down on all food, otherwise your
body will go into "starvation mode" where your metabolism reduces, to save
energy, making it impossible to lose weight, and then in the long run you'll be even fatter. Cut out the fatty sweets (chocolate, various candy) and food (bacon, pizza, fast food), and switch to healthy alternatives eg instead of white bread, eat brown bread. Instead of coffee or hot chocolate, have plain semi skimmed milk. Also eat more greens such as apples and especially banana's. Even if youre tempted, pinch yourself, asking "do I really want this?", or do things that get your mind of things like tempting food.
Make sure you join the
gym and ask your trainer or people here for a nice
cardio/weight loss programme! Good luck with your
weight loss!
