1.5 months is not a long time...be patient
You don't notice any change at all? How are your mood, energy, endurance, strength? No difference at all?
Also, what about your hair, nails, skin etc? Your digestion?
There are many things that start to heal once you go vegan and start raw 'till 4. Maybe you don't lose weight because your body is busy healing other stuff in your body.
And also, how much sleep do you get? That is really important.
Remember, weightloss shouldn't be the goal, but more like a "bonus" of having perfect health after a few years. :)
Your body doesn't agree..
You're very young and VERY active. I'm 22 and not nearly as active as you are yet I also eat 2,500-3000kcal a day. I'm not an expert but I really think you need to eat more. Also, make sure you get some good veggies into your diet if you haven't already been. One last thing to try is having your b12 levels checked in the near future, in case you decide to stick with this lifestyle. You will probably benefit from b12supplements.

Most important thing, eat more!!
