How to tone up love handles and thighs FAST?

I'm leaving to Europe in 6 days, and today while i was shopping i noticed i put on plenty of weight over summer vacation. I usually always had a problem with love handles and i can never get rid of them. I'm a very insecure 15 year old who just wants to look good and feel good. I also have always had HUGE theighs and i'm really insecure about my body. To be honest, it's hard to find a diet for me that works because as a teen i want to consume the junk foods and stuff like that. But i'm lazy to work it off. I am a person that's committed to anything, if i set my mind to it. What's the QUICKEST way i can get my love handles, thighs, and kinda my butt toned up before i leave for my trip to Europe? Please, Please, Please help.
