How to lose weight fast?

Is it possible to lose 15 kgs in 2-3weeks. I thought I had like 5 weeks but I cheecked my calendar and I've only got like 2 and a half weeks until I have this big event coming up and I want to be in my bmi range.

It sounds like a pretty dangerous thing to do- dropping that much weight in 2 weeks can't be healthy at all. I suggest that, should you desire to lose some weight or tone up, set more realistic goals (ie: a kilo every 2 weeks), and put systems in place to achieve them. These include planning out a healthy diet with fruit, veges, meat, and a few treats here and there, as well as a certain amount of exercise.

All the best!

I have noticed that by eating healthy, drinking a lot of water, exercising and taking Isagenix I have lost weight and inches. Its really great! Its really healthy too! This is where I buy the product http://www.reallyhealthychoices.isagenix.com. They have this 9-day program that you can lose between 5-20lbs. So its great and works!
I hope this helps and Good Luck!
