If you only need to loose 5kg then you dont NEED to loose anything really. And if your that close to your correct weight range it will take more then a few weeks to loose it.
And talk to your mom and let her know you want to loose some weight and ask her if she can help by cooking healthier at dinner. And not having a car is a good thing means you have to walk everywhere, which is great. WALK WALK WALK!!!
