now really to the point u have aboslutely nothing to worry about..just eat healthy... according to a food guide which u can find on the internet easily and excercise 3-4 times a week and in to time you'll notice a difference
since i know that u feel so bulky and insulted about it,but i had this problem also when i was 18(now 20).my weight was 72,but now it is 58.i'm feeling very much better now .so here is the solution
1.don't eat ur lunch(11:00 breakfast,2:00 pm lunch and dinner).
2.drink grean tea a lot when u feel hungry.
3.and do the exercise like running and crunches better u start gym.
4.and play sports.
that's all i did .i played too much cricket and i reduced my weight around 1 5kg.
so that's all i can answer .
best off luck coco
